I-15 Bangerter Highway Interchange (Exit 295): Utah Accident Law, Corridor Data, and Your Rights

Interstate 15 Exit 295 in South Jordan is where one of Utah's highest-volume freeways meets one of Salt Lake County's busiest east-west arterials. Bangerter Highway now carries more than 60,000 vehicles per day through the corridor that converges at this interchange (UDOT, November 21, 2025). On November 21, 2025, UDOT held a ribbon-cutting completing the four-interchange conversion that turned Bangerter into a free-flowing facility from I-15 in Draper to 4100 South in Taylorsville. The geometry at Exit 295 just changed in a way that will reshape crash patterns for years. If you were hurt in an I-15 Bangerter accident, this analysis covers what the data shows, the November 2025 milestone and what it means for crash patterns going forward, the engineering reasons specific scenarios recur, and the Utah legal framework that controls your claim.

The Bangerter Exit 295 interchange by the numbers

Exit 295 connects I-15 to Bangerter Highway (Utah State Route 154), the principal east-west arterial serving South Jordan, West Jordan, Taylorsville, and West Valley City. I-15 Bangerter accident data is published by UDOT through its Crash Data Portal and Numetric public dashboards; federal fatals are tracked in NHTSA FARS; statewide patterns appear in the Utah Highway Safety Office Crash Facts. The Salt Lake City Vision Zero Crash Dashboard provides corridor-specific validation for SLC arterials.

Traffic volume and corridor profile

The Bangerter corridor feeding Exit 295 carries some of the heaviest sustained arterial volume in the Mountain West. UDOT's November 21, 2025 release places daily volume at more than 60,000 vehicles per day, with I-15 ramps absorbing a substantial share during weekday peaks. South Jordan, West Jordan, Taylorsville, West Valley City, Herriman, and Riverton residents use Bangerter as the primary east-west route. Exit 295 is the I-15 terminus, and the most common I-15 Bangerter accident location.

The corridor record relevant to an I-15 Bangerter accident:

• I-15 statewide in 2024: 25 fatalities, Utah's deadliest highway that year (KSL Safety Solutions feature).
• Utah statewide 2024: 281 preliminary traffic fatalities January 1 to December 31, 2024 (UDOT and DPS, January 7, 2025).
• Bangerter Highway daily volume: more than 60,000 vehicles per day in the I-15 to 4100 South corridor (UDOT, November 21, 2025).
• Bangerter crash history: the Upper Great Plains Transportation Institute documented 949 crashes at Bangerter and 5400 South alone between 1994 and 2003 (UGPTI MPC-05-176). UDOT has converted at least 10 Bangerter signalized intersections to grade-separated interchanges or Continuous Flow Intersections since 2012, with four more conversions ribbon-cut in November 2025 (UDOT Bangerter program).
• Bangerter program investment: approximately $805 million in environmental studies plus construction across the multi-year program (UDOT).
• Travel-time savings post-conversion: approximately 8 minutes across the corridor per UDOT post-completion estimate (UDOT, November 21, 2025).
• Recent corridor fatalities in the broader study area: a multi-vehicle DUI crash in December 2025 near 2200 West and 5400 South in Taylorsville (ABC4, FOX 13); a six-vehicle fatal near 4100 South the same month; and a November 2025 motorcycle crash near Bangerter at 600 West in Draper (KSL, KSLTV).

Per-exit crash counts for Exit 295 are part of the broader UDOT dataset and accessible via a Government Records Access Management Act (GRAMA) request to UDOT Traffic and Safety. The Bangerter corridor is one of the 10 locations profiled in our parent data study, "Utah's 10 Most Crash-Prone Intersections (2026 UDOT Data Study)."

State and county context

Utah's fatality rate has run materially above the U.S. national rate every year from 2020 through 2024 per NHTSA FARS (FARS Encyclopedia). Salt Lake County alone accounts for roughly 26 percent of statewide fatalities per the Utah Highway Safety Office 2026 Problem ID. Behavioral factors in Utah fatalities: speed (33 percent), failure to keep proper lane (30 percent), no restraint (30 percent), impairment (21 percent), failure to yield (15 percent). All five appear in the documented I-15 Bangerter accident mix.

November 21, 2025: the Bangerter Highway freeway conversion is complete

The single most important traffic-engineering event affecting Exit 295 in the past decade happened on November 21, 2025. UDOT held a ribbon-cutting marking the completion of the four-interchange conversion that turns Bangerter Highway into a free-flowing facility from I-15 in Draper west to 4100 South in Taylorsville. The four conversions completed in 2025 were at 4700 South, 9800 South, 13400 South, and 2700 West. Construction on this phase began in summer 2023. UDOT estimates the conversion produces an 8-minute travel-time savings across the corridor compared with the pre-conversion signalized configuration (UDOT, November 21, 2025).

UDOT Region Two Director Robert Stewart framed the November 2025 completion this way: "part of a long-term vision to make travel safer and more predictable" (UDOT release, November 21, 2025). The project added a pedestrian bridge at 9800 South, removing a high-friction at-grade pedestrian crossing from the corridor.

What this means for I-15 Exit 295 specifically

The conversion shifts the geometry for every vehicle approaching Exit 295 from the west. Pre-November 2025, a driver heading east on Bangerter to reach I-15 traversed a sequence of signalized intersections at arterial speeds, decelerating and accelerating multiple times before the I-15 on-ramps. Post-conversion, that same driver maintains free-flow speeds the entire distance until the I-15 ramp transition. Three predictable changes in the I-15 Bangerter accident pattern at Exit 295 follow:

• Speed differentials at the I-15 entry transitions will increase. A driver arriving at the I-15 ramps from a now-free-flowing Bangerter is approaching at higher speeds than the previous signalized configuration produced.
• Bangerter-side T-bone collisions at the removed signals fall to zero. Right-angle crashes are by definition signalized-intersection events. Signal removal engineers that crash type out of the corridor.
• Crash severity shifts up. Free-flowing facilities produce fewer crashes overall but higher-severity crashes when they occur, because closing speeds are higher. Highway Safety Manual analysis is consistent on the tradeoff.

None of these predictions is certain. We will know with confidence when UDOT publishes 2026 and 2027 I-15 Bangerter accident data (the 2025 dataset finalizes mid-2026; full year-after data requires the 2026 reporting cycle). This analysis will be updated annually each May. See Annual Update Commitment.

The Bangerter Highway transformation timeline (2012-2027)

UDOT's Bangerter Highway program is the longest-running corridor-safety conversion in Utah history. The agency has methodically removed signalized intersections from the highway and replaced them with Continuous Flow Intersections (CFI), then with full grade-separated interchanges, then ultimately with freeway-style configurations. The pattern is documented at the UDOT Bangerter program page. The table below compiles every documented conversion from the program era forward, with the November 2025 completions and the 2027+ next phase explicitly flagged.

The November 2025 conversions added the 9800 South pedestrian bridge to replace the at-grade crossing. The next phase, anticipated 2027, extends the free-flow facility from 4100 South north to California Avenue. When that phase completes, the entire Bangerter corridor from I-15 in Draper to SR-201 will be free-flowing.

Why the I-15 Bangerter exit produces the crashes it does: the traffic engineering

Crash patterns at any interchange follow the geometry. Six design factors converge at Exit 295. Each has a documented engineering basis in the AASHTO Green Book on Geometric Design of Highways and Streets, the FHWA Highway Safety Manual, and NHTSA crash research.

1. Deceleration physics: stopping distance at freeway speeds

A driver's stopping distance scales with the square of speed. Standard AASHTO Green Book stopping-sight-distance approximations (2.5-second perception-reaction plus deceleration) put stopping distance at roughly 730 feet at 70 mph, roughly 820 feet at 75 mph, and roughly 360 feet at 45 mph (typical ramp speed). Source: FHWA Highway Safety Manual; cross-checked with NACTO references. A driver who fails to perceive a slowing ramp queue on Exit 295 at full freeway speed needs more than two football fields to stop. The Bangerter ramp deceleration lane is shorter than that. Most ramp-deceleration rear-ends in an I-15 Bangerter accident happen inside that physics gap.

2. The diverge-lane sight distance problem

Exit 295's diverge lane splits from the right-hand travel lane. Sight distance in the diverge is limited by ramp curvature and the screening effect of large vehicles. AASHTO methodology treats this as a "decision sight distance" problem rather than a stopping sight distance problem. NHTSA crash sampling consistently associates decision-sight-distance failures with interchange-diverge rear-end and sideswipe events.

3. Bangerter on-ramp acceleration constraint

Bangerter Highway feeds I-15 north and south through adjacent on-ramps at Exit 295. Drivers entering I-15 from Bangerter must accelerate to within roughly 10 mph of through-lane I-15 traffic before the merge ends. Acceleration distance is constrained by ramp length, grade, and sight line. A driver who cannot complete the acceleration yields from a near-stopped position, producing rear-end collisions from following Bangerter traffic. Right-of-way is governed by Utah Code Section 41-6a-901.

4. Speed-differential rear-end correlation

NHTSA crash data show interchange-entry speed differentials are among the highest-correlation factors for Interstate rear-end collisions (NHTSA Speeding research). A 30 mph closing speed between two vehicles in the same lane carries roughly six times the kinetic energy of a 12 mph closing speed. The gap between freeway-speed and ramp-speed traffic at Exit 295 sits exactly in the highest-risk band.

5. Construction-zone compounded risk

Bangerter's multi-year conversion meant active construction zones along the corridor from 2012 through November 2025. Active construction zones narrow lanes, shift travel paths week-to-week, and increase rear-end exposure. The California Avenue to 4100 South phase anticipated for 2027+ will reopen that risk window during its construction period.

6. Weather and visibility

Salt Lake County winter weather (snow, freezing fog, low-angle winter sun) produces visibility events that compound every other geometric factor in an I-15 Bangerter accident. KSL has reported multi-vehicle weather-event crashes on I-15 producing 30 to 55 simultaneous crashes during a single storm morning. The Point of the Mountain segment immediately south of Exit 295 is the most-cited regional example.

Comparison: I-15 Exit 295 versus other I-15 Salt Lake County exits

I-15 in Salt Lake County is the highest-volume interstate segment in Utah. The table below puts Exit 295 in context against the other major I-15 exits in the county. Crash-type patterns are drawn from UDOT, KSL, and Numetric data plus the UHP jurisdiction record. Honest framing: record-level crash counts per individual exit require a GRAMA request to UDOT Traffic and Safety. The patterns below describe the corridor types, not precise per-exit fatality counts.

Ramp rear-ends and merge collisions dominate every exit in the table. Exit 295 sits in the middle of the corridor, with the unique feature that its Bangerter approach now offers free-flow speeds for the first time in the corridor's history. Exit 290 (Point of the Mountain) and the Beck Street complex (310-313) are the two segments KSL has explicitly named in Utah's deadliest-highway feature; Exit 295 has not appeared on those lists individually, but the broader Bangerter corridor has been the subject of UDOT's largest single corridor-safety investment in Utah history at roughly $805 million.

The 5 most common crash scenarios at Bangerter Exit 295

Five fact patterns recur in I-15 Bangerter accident cases at and around Exit 295. Each carries a specific Utah Code framework. We expand each below with the controlling statute, the mechanics, a hypothetical worked example, and what we tell clients in the first call on that scenario.

Scenario 1: Rear-end during ramp deceleration

The most common I-15 Bangerter accident scenario at Exit 295. A driver decelerates from freeway speed into the exit ramp; a following driver fails to leave safe stopping distance and impacts from behind. The deceleration is mandatory; the rear-end is engineering-predictable. Utah Code Section 41-6a-711 (following too closely) requires that a driver "may not follow another vehicle more closely than is reasonable and prudent." Utah case law applies a strong rebuttable presumption that the trailing driver bears primary liability, rebuttable only by specific evidence of an unforeseeable event (sudden lane change, brake-light failure, object from a third vehicle).

Damages in a typical ramp-deceleration I-15 Bangerter accident follow predictable patterns: emergency-department evaluation, cervical and lumbar strain (most commonly at C5-C6 and L4-L5), possible disc herniation on MRI, several months of physical therapy, and at higher closing speeds, concussion or mild traumatic brain injury. Documented economic damages typically run $25,000 to $80,000 for moderate cases; pain and suffering multiplies that range. See our "How Much Is a Utah Personal Injury Case Worth?" parent pillar and "Utah Settlement Value Library" for comparables.

Scenario 2: Merge collision between freeway and Bangerter on-ramp

A second recurring I-15 Bangerter accident pattern. A Bangerter driver enters the I-15 on-ramp, accelerates through the merge, and either fails to reach freeway speed or misjudges the gap. Right-of-way is governed by Utah Code Section 41-6a-901, which requires drivers on intersecting roadways to yield to vehicles on the through highway. NHTSA Crash Statistics classifies freeway-merge crashes as a high-frequency, high-cost category. Post-November 2025, drivers approach the I-15 ramps from a free-flowing Bangerter rather than a signalized corridor, which is expected to reduce "merge from a near-stop" events while increasing through-speed differential at the merge itself. Liability turns on dashcam, third-party witnesses, vehicle positioning, and (in commercial-vehicle cases) ECM black-box data. Comparative-fault findings of 70/30 or 80/20 are common.

Scenario 3: Sideswipe in the diverge lane

A driver decides late to take Exit 295 and changes lanes into the diverge without verifying it is clear, colliding with a driver already decelerating. Or a driver in the diverge abandons the exit and returns to the travel lane, sideswiping a following I-15 through-driver. Utah Code Section 41-6a-710 requires that "a person may not turn a vehicle or move right or left upon a roadway... until the movement can be made with reasonable safety." The lane-changing driver carries the burden. Sideswipe at 15 to 25 mph closing speed produces rotational forces severe enough to cause rib fractures, shoulder labral tears, and cervical strain. At higher closing speeds, vertebral compression fractures and rotational shoulder dislocations appear; injury profile typically requires orthopedic referral.

Scenario 4: Commercial truck crash on the ramp

A commercial-vehicle I-15 Bangerter accident is the highest-dollar category at Exit 295. I-15 carries heavy freight; Bangerter interfaces with I-215 and the broader Utah freight network. A Class 8 tractor-trailer that fails to decelerate adequately into the Exit 295 ramp, or that takes the ramp at excessive speed and loses load stability, can produce a multi-vehicle crash with disproportionate damages. FMCSA regulations govern interstate motor carrier operations: hours-of-service (49 CFR Part 395), driver qualification (Part 391), maintenance (Part 396), load securement (Part 393). Utah CMV rules sit at Title 72 of the Utah Code, overseen by the UHP Motor Carrier Section. The full FMCSA evidence trail is laid out in "Utah Commercial Truck Accident Lawyer."

Scenario 5: Hit-and-run on the ramp shoulder

A driver in a low-speed contact on the ramp or merge zone leaves before the other party can identify them. The narrow shoulder at Exit 295 makes it easy to pull onto Bangerter and disappear within seconds. When the at-fault driver cannot be identified or has no insurance, the injured party's own Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverage steps in. Utah's UM/UIM statute is Utah Code Section 31A-22-305. Utah requires insurers to offer UM/UIM; insureds may waive only in writing. UM/UIM is often the only collectible recovery in a hit-and-run I-15 Bangerter accident. Pedestrians struck on or near the ramp shoulder face the same UM/UIM analysis under their household auto policy. We treat that scenario in "Utah Pedestrian Accident Law."

Expert observations from BAM Managing Attorney Kigan Martineau

The following three observations are presented as quote-ready paragraphs for reporters covering Utah traffic safety. Each is a position BAM is prepared to defend on the record and (with Kigan's sign-off before publication) speak to on camera.

"Bangerter's arterial-to-freeway conversion is one of the most consequential traffic-engineering shifts in Salt Lake County in twenty years. The pre-conversion I-15 Bangerter accident mix was dominated by signalized-intersection T-bones west of I-15 and ramp rear-ends at the I-15 entry. The post-November-2025 corridor should flip that mix: fewer T-bones because signals are gone, but higher closing speeds at the I-15 ramp transitions because Bangerter-side drivers are now arriving from free-flow conditions. We will know how the math actually settles when UDOT publishes 2026 and 2027 data." Kigan Martineau, Managing Attorney, BAM Injury Law (safety-engineering observation) [KIGAN BLOCK QUOTE. Verify with Joseph before publish.]

"The carrier on the other side of an I-15 Bangerter accident begins building their comparative-fault narrative within 72 hours. That is why the recorded-statement request comes so fast. The carrier is trying to capture an admission that can push your share of fault from 10 percent to 30 percent, ultimately arguing you are 50 percent or more responsible under Utah Code Section 78B-5-818, which would bar recovery entirely. The single most important thing a hurt driver does in those first three days is decline that statement and get medically documented." Kigan Martineau, Managing Attorney, BAM Injury Law (claims-process observation) [KIGAN BLOCK QUOTE. Verify with Joseph before publish.]

"The thirty minutes after an I-15 Bangerter accident decide more than people realize. Photograph everything before vehicles are moved. Get the dashcam SD card out before the tow truck. Lock down two witnesses by phone before they drive off. Decline the other driver's insurer when they call. See a doctor within 24 to 72 hours and report every symptom, even minor ones. Treatment gaps and unreported symptoms are the two arguments most often used to reduce settlement value, and they are both preventable in those first three days." Kigan Martineau, Managing Attorney, BAM Injury Law (immediate-action observation) [KIGAN BLOCK QUOTE. Verify with Joseph before publish.]

Salt Lake County jurisdiction: filing your I-15 Bangerter accident claim

Exit 295 sits in Salt Lake County, with the South Jordan / West Jordan municipal boundary just west of the interchange. I-15 Bangerter accident claims are filed in Salt Lake County District Court (Utah Third District) when damages exceed the small-claims cap. Utah Rule of Civil Procedure 26 requires initial disclosures within 14 days of the answer; missing it can produce evidence preclusion and adverse-inference sanctions. Discovery is governed by tiered limits under Rule 26(c) keyed to damages tier.

The Third District courthouse is at 450 South State Street, Salt Lake City, UT 84111. Filing is electronic via the Utah Courts e-filing portal.

The statute of limitations is the controlling deadline for any I-15 Bangerter accident claim. Utah personal injury claims must be filed within 4 years under Section 78B-2-307(3). Wrongful death claims within 2 years under Section 78B-2-304(2). Claims against a Utah municipal or state agency (UDOT for alleged unsafe interchange design) require a separate Notice of Claim within one year under Section 63G-7-401 (Governmental Immunity Act of Utah). Missing any deadline forfeits the corresponding claim entirely.

Utah follows modified comparative negligence with a 50 percent bar under Section 78B-5-818. Recovery is reduced by your fault percentage; at 50 percent or more, recovery is barred entirely. This is stricter than pure comparative-negligence states (Washington, California) and parallel to Idaho (Idaho Code Section 6-801). See "Utah's Modified Comparative Negligence 50 Percent Bar."

What to do if you crashed at I-15 Bangerter Exit 295 (with Salt Lake County specifics)

The first 30 minutes after an I-15 Bangerter accident are when most case-determining evidence is created and lost. The expanded 12-step checklist below is what we walk through with clients on the first call, with Salt Lake County hyperlocal specifics built in.

1. Move to safety if you can. If vehicles are drivable, clear the travel lane. UDOT incident management protocols call for moving disabled vehicles to the shoulder to prevent secondary crashes, which are a recurring problem on I-15. If your vehicle is not drivable, hazard lights on, stay buckled, wait for emergency response, do not exit into the travel lane.
2. Call 911. I-15 is patrolled by the Utah Highway Patrol (Section 3 covers the I-15 Salt Lake County segment) as the primary agency on Interstate highways. Request medical response if injured. A UHP report is essential evidence. The Salt Lake County dispatch number for non-emergency follow-up is the standard county dispatch line.
3. Get to an emergency room within 24 to 72 hours. The two nearest full-service ERs to Exit 295 are Intermountain Medical Center (5121 South Cottonwood Street, Murray, UT 84107, approximately 8 miles north) and Jordan Valley Medical Center (3580 West 9000 South, West Jordan, UT 84088, approximately 6 miles west). Both run Level III trauma capability. The treatment gap is the most common defense argument used to reduce settlement value; the 24-72 hour window matters more than people realize.
4. Photograph the scene before vehicles are moved. Wide shots of ramp geometry, lane positions, skid marks, debris, road defects, and the I-15 / Bangerter signs. Close shots of damage, plates, the other driver's insurance and registration, and injuries. Pre-move photographs are often the single most decisive evidence in a contested-liability case.
5. Get witness contact information. Witnesses leave fast on freeways. Get name, phone, email at minimum. A supporting witness can swing a 50/50 dispute to 80/20.
6. Decline a recorded statement to the other driver's insurance. Their adjuster calls within 24 to 72 hours. You have no legal obligation. Anything you say will be used to reduce your settlement or manufacture a comparative-fault hook. Refer them to your attorney. Your own insurer is different; the policy's cooperation clause requires a statement to your own carrier.
7. Report every symptom to the treating physician. Neck, back, headache, dizziness, tinnitus, sleep disruption, mood changes. Symptoms that go unreported in the medical record become almost impossible to claim later. The medical record is the legal record.
8. Preserve dashcam and business camera footage. Pull the dashcam SD card immediately before the vehicle goes on the tow truck. Nearby business cameras (gas stations near the on-ramps, retail on Bangerter, freight yards) typically retain footage 30 to 90 days before overwrite. A preservation letter in the first two weeks is often the difference between having footage and having none. Your attorney sends the letters.
9. Document lost wages thoroughly. Employer letter with your rate, dates missed, and any modified-duty accommodation. Pay stubs, W-2s. Self-employed: bank statements, invoices, tax returns. Salt Lake County's commuter population means a high percentage of Exit 295 crashes involve missed work for traffic-pattern reasons in addition to the medical reasons.
10. Track all out-of-pocket expenses. Medication co-pays, mileage to medical appointments, durable medical equipment, home modifications, child care during appointments. Each is recoverable as past special damages.
11. If UDOT or a government entity may be responsible, file the Notice of Claim within one year. The Utah Governmental Immunity Act under Utah Code Section 63G-7-401 requires a Notice of Claim within one year of injury. Missing this deadline forfeits any government-defendant claim, full stop. The Notice is filed with the entity itself plus the Utah Attorney General if a state agency is involved. UDOT GRAMA requests for incident records go to UDOT Public Records via the request portal.
12. Contact a Utah personal injury lawyer. An experienced attorney sends preservation letters, obtains the certified UHP report, coordinates medical-record collection, calculates the full damages stack, and handles every insurance communication. The Insurance Research Council Auto Injury Insurance Claims Study consistently finds attorney-represented claimants recover substantially more than unrepresented claimants.

BAM's Murray office and the I-15 Bangerter exit

BAM Injury Law's Salt Lake County office sits at 310 East 4500 South, Suite 550, Murray, UT 84107, about 9 miles north of Exit 295 via I-15. Drive time 12 to 18 minutes outside rush hour. The Murray office handles every I-15 Bangerter accident scenario covered above: ramp-deceleration rear-ends, merge collisions, diverge sideswipes, commercial truck cases under FMCSA evidence rules, and hit-and-run UM/UIM under Utah Code Section 31A-22-305. Our attorneys appear in Utah Third District Court on State Street. Free case evaluations; no fee unless we recover.

Worked example: rear-end on the ramp (hypothetical)

Illustrative only. Not a representation of any specific past BAM case or any guarantee of result.

A hypothetical I-15 Bangerter accident. Plaintiff (41, South Jordan) decelerates from freeway speed into the Exit 295 ramp at 50 mph. A following F-150 fails to leave safe stopping distance and impacts the rear at 25 mph closing speed. Airbag deploys; plaintiff is transported to Intermountain Medical Center. Diagnoses: cervical strain at C5-C6, lumbar strain at L4-L5 with disc bulge on MRI, concussion graded mild TBI with persistent symptoms over six weeks. Out 4 weeks, modified duty 6. Dispute over deceleration reasonableness produces a 10 percent comparative-fault finding.

Actual numbers in any I-15 Bangerter accident depend on documented severity, available policy limits, plaintiff UM/UIM coverage, liability evidence, and medical-record continuity.

BAM's approach to I-15 Bangerter exit cases

Where I-15 Exit 295 sits in Utah's deadliest-corridor context

Our parent data study ranked Utah's 10 most crash-prone intersections using a weighted Intersection Safety Index. The Bangerter Highway corridor (Taylorsville to West Jordan) ranked #5, with the I-15 Bangerter exit operating inside that broader corridor. Other ranked corridors include Bluff Street and 500 North in St. George (#1), State Street from SLC to Midvale (#2), Redwood Road from California Avenue to 1000 North (#3), I-15 at Point of the Mountain (#4), Mountain View Corridor in Herriman (#6), and US-89 / Beck Street (#7).

The Bangerter corridor is rare in the list because it is the only Utah corridor where UDOT has spent close to a billion dollars converting the geometry away from the configuration that produced the crash burden. The other ranked corridors still operate in the configurations that produce their documented crash patterns. Bangerter is becoming the engineering experiment. The next 24 to 36 months of UDOT data on the I-15 Bangerter accident mix will tell us whether the conversion produced the predicted safety dividend.

Frequently asked questions

Why is the I-15 Bangerter exit so dangerous?

Exit 295 combines three dynamics: a high-volume freeway (I-15 was Utah's deadliest highway in 2024 with 25 fatalities per KSL), a deceleration ramp with a significant speed differential (70 to 75 mph posted to 35 to 45 mph ramp speed in a few hundred feet), and the Bangerter Highway arterial feeding traffic on through adjacent on-ramps. The Bangerter corridor has a long-documented crash history that triggered UDOT to remove 10+ signalized intersections since 2012 and complete a free-flowing conversion in November 2025. The combination produces rear-end, merge, and sideswipe collisions.

Has Bangerter Highway gotten safer with the 2025 interchange conversions?

UDOT completed the four-interchange conversion (4700 South, 9800 South, 13400 South, 2700 West) on November 21, 2025, making Bangerter free-flowing from I-15 to 4100 South. Engineering intuition says yes, fewer crashes overall (signal removal eliminates T-bone right-angle crashes by definition) but possibly higher closing speeds at the I-15 ramps where Bangerter traffic now arrives from free-flow conditions. We will know with statistical confidence in 18 to 24 months when UDOT publishes 2026 and 2027 crash data.

How does UDOT publish crash data for Utah interchanges?

UDOT publishes crash data through two primary channels: the UDOT Crash Data Portal at connect.udot.utah.gov, which provides annual Crash Facts reports and aggregated dashboards, and the Numetric public dashboards at udot.numetric.net, which provide more detailed statewide views. Record-level crash counts at specific intersections or interchanges require a Government Records Access Management Act (GRAMA) request to UDOT Traffic and Safety. Federal cross-validation for fatal crashes is available via the NHTSA Fatality Analysis Reporting System (FARS).

Who has jurisdiction over crashes at Bangerter Exit 295?

Exit 295 is in Salt Lake County. The Utah Highway Patrol (Section 3) is the primary agency on Interstate highways. Personal injury claims are filed in Salt Lake County District Court (Utah Third District) when damages exceed the small-claims cap. The road is operated by UDOT. Claims alleging that interchange design contributed to the injury are governed by the Utah Governmental Immunity Act, requiring a Notice of Claim within one year of injury under Utah Code Section 63G-7-401.

What if I was rear-ended on the Bangerter exit ramp?

Utah law strongly favors the lead driver. Section 41-6a-711 prohibits following too closely; Utah case law applies a strong presumption that the trailing driver is primarily liable. Photograph lane positions before vehicles are moved, get witness contacts, preserve dashcam, see a doctor within 24 to 72 hours, decline a recorded statement to the other driver's insurance, and contact a Utah personal injury attorney before negotiating any I-15 Bangerter accident claim.

What if a commercial truck hit me on the Bangerter exit?

FMCSA regulations cover hours-of-service, driver qualification, inspection, and load securement; Utah CMV rules are overseen by the UHP Motor Carrier Section. The evidence trail is much broader than a passenger-vehicle case: driver qualification file, HOS / ELD logs, ECM black-box, post-accident drug and alcohol, dispatch, lease, maintenance. Many records have a 6-month preservation window. Motor carrier policies often run $1 million to $5 million.

How long do I have to file a claim after a Bangerter exit crash?

Utah's general personal injury SOL is 4 years from injury under Section 78B-2-307(3). Wrongful death is 2 years under Section 78B-2-304(2). Claims against UDOT or any Utah government agency require a Notice of Claim within one year under Section 63G-7-401 (Governmental Immunity Act of Utah). Missing the one-year notice forfeits the government-defendant claim permanently.

Should I give a recorded statement after a Utah freeway crash?

Not to the other driver's insurance. Their adjuster calls within 24 to 72 hours; you have no obligation. Anything you say will be used to reduce settlement or manufacture a comparative-fault hook. Refer them to your attorney. Your own insurer is different: the policy's cooperation clause requires a statement to your own carrier.

What is the average settlement for an I-15 freeway crash in Utah?

There is no single "average" because settlement value scales with severity, policy limits, comparative-fault percentage, and liability evidence. Moderate-severity rear-ends with no permanent impairment typically land in a high five-figure to low six-figure range; commercial-vehicle crashes can reach seven figures because motor carrier policies stack. See our Utah Settlement Value Library for comparables.

How long does an I-15 personal injury case take in Salt Lake County?

Most Utah personal injury cases resolve in 9 to 18 months once the injury reaches maximum medical improvement (MMI) and settlement negotiations conclude. Cases that require litigation in Utah Third District Court typically run 18 to 30 months from filing to trial. Commercial truck and contested-liability cases tend to run longer.

Does Utah's no-fault insurance apply to I-15 freeway crashes?

Yes. Utah is a no-fault auto insurance state; Personal Injury Protection (PIP) pays the first portion of medical bills and lost wages regardless of fault. Utah's PIP minimum is $3,000. The no-fault threshold (typically $3,000 in medical bills, plus dismemberment, permanent disability, permanent disfigurement, or death) must be crossed before a tort claim against the at-fault driver can proceed.

What is the difference between a UM and a UIM claim after an I-15 hit-and-run?

Uninsured Motorist (UM) applies when the at-fault driver had no insurance or in a hit-and-run where the driver is not identified. Underinsured Motorist (UIM) applies when the at-fault driver had insurance but policy limits are insufficient. Both governed by Section 31A-22-305. UM/UIM is filed against your own carrier and is adversarial despite that posture.

Should I file a Notice of Claim against UDOT after an I-15 Bangerter crash?

Possibly. Section 63G-7-401 (Governmental Immunity Act of Utah) requires a Notice of Claim within one year of injury if a government entity may have contributed (unsafe design, signal operation, maintenance failure). Utah's statutory immunity is broad; not every dangerous-design claim is viable. Filing the notice preserves the option; not filing forfeits it permanently.

What is comparative fault, and how does it apply to a Bangerter crash?

Utah follows modified comparative negligence with a 50 percent bar under Section 78B-5-818. Recovery is reduced by your fault percentage; at 50 percent or more, recovery is barred. A typical 90/10 rear-end finding leaves the lead driver with a 10 percent reduction. A 70/30 merge finding can leave a through-driver with a 30 percent reduction.

Can I sue both the driver and the trucking company in a Bangerter truck crash?

Yes. In most commercial-vehicle crashes, both the driver and the carrier are proper defendants. The carrier may be vicariously liable (scope of employment) and directly liable (negligent hiring, training, supervision, maintenance). Brokers and shippers can sometimes also be defendants. FMCSA evidence is essential.
