South Salt Lake's Most Dangerous Roads

The figures come from placing every UDOT crash record inside the city's present-day limits onto the street where it occurred, based on the state road map and the road the investigating officer wrote down. Freeway and ramp crashes are tallied separately, and crashes on private property, such as parking lots, are excluded from the street ranking. A crash is called serious or fatal here when someone died or was recorded with a suspected serious injury.

Of the 9,824 crashes, 4,829 were on freeways and ramps, 123 on private property, and 103 could not be matched to a street. The other 4,769 were on surface streets, where 127 crashes were serious or fatal (2.7%) and 25 people were killed. Across the seven counties in this data set, Salt Lake, Utah, Davis, Weber, Summit, Cache and Washington, 2.6% of street crashes were serious or fatal. An injury, including a possible injury, was reported in 35.5% of South Salt Lake street crashes, compared with 32.1%.

Half the Crashes, Few of the Deaths

Freeways and ramps account for 49.2% of every crash recorded in South Salt Lake. Across the seven counties, the freeway share is 21.4%. I-15 alone had 3,507 crashes inside the city and I-80 had 1,168.

The freeway crashes were far less likely to be serious. I-15, I-80 and the ramps produced 39 serious or fatal crashes among 4,829, about 0.8%, and 4 deaths. The streets produced 127 among 4,769, and 25 deaths. On these records, a crash on a South Salt Lake street was more than three times as likely as a freeway crash to end in death or serious injury.

South Salt Lake Streets by Crash Count

Ranking is by the number of crashes UDOT placed on each street inside city limits, January 2018 through August 4, 2025. Cross streets are listed where the street's own crash count is highest.

• State Street (US-89) — 1,101 crashes, 34 serious or fatal, 3 deaths. 245 of them were at 3300 South, 8 of those serious or fatal, and 88 at 2400 South. Pedestrians were involved in 13 of its serious or fatal crashes.
• 3300 South (SR-171) — 871 crashes, 21 serious or fatal, 7 deaths. Its busiest junctions are 300 West (92), 900 West (74) and 500 West (60). Rear-end crashes are 41.9% of the total, and UDOT's traffic estimates reach about 52,000 vehicles a day.
• Main Street — 418 crashes, 12 serious or fatal, 2 deaths. Side impacts are 59.3% of its crashes, and officers recorded a driver disregarding a signal or sign in 97 of them, both the highest shares among these ten. 3300 South (120) is its busiest junction.
• West Temple — 256 crashes, 10 serious or fatal, no deaths. 110 of its crashes, 5 of them serious or fatal, were at 3300 South.

These ten streets hold 3,710 of the city's 4,769 street crashes, 77.8%, along with 105 of the 127 serious or fatal crashes and 19 of the 25 deaths. 3300 South runs through almost all of them: for nine of the ten, it is the cross street where crashes collect most, or it is the street itself.

Seven Deaths on 3300 South

By serious or fatal crashes, State Street leads with 34 and 3300 South follows with 21, then Main Street (12) and West Temple (10). Deaths tell a different story: 3300 South had 7, more than any other South Salt Lake street, and each came in a separate crash. 2700 South, outside the top ten with 62 crashes, has the highest serious-or-fatal share among the city's fifteen busiest streets at 6.5%, with 2 deaths. Highway 201 inside the city had 118 crashes and 1 fatal crash; it counts toward the street total but is not ranked.

Pedestrians, Impairment and Ignored Signals

People on foot bear a heavy share of the harm. Pedestrians were involved in 2.9% of South Salt Lake street crashes but in 38 of the 127 serious or fatal ones, 29.9%, nearly double the 15.1% across the seven counties. Motorcyclists were in 30 of them. UDOT's single-vehicle or not-applicable group, where a car striking a pedestrian or cyclist is recorded, accounts for 54 of the serious or fatal crashes.

Officers flagged a driver disregarding a signal or sign in 10.9% of street crashes, against 7.8% across the seven counties, and in 23 of the serious or fatal ones. Impairment was flagged in 14 serious or fatal crashes, 11.0% of them, against 7.7%. A driver left the scene in 13.0% of crashes, against 8.6%. Ten crashes involved a train and 53 a transit vehicle.

I-15 and I-80 Up Close

I-15 inside South Salt Lake had 3,507 crashes, 31 serious or fatal and 2 deaths. More than half, 54.9%, were rear-end collisions, and officers flagged speed in 1,470. I-80 had 1,168 crashes, 6 serious or fatal and 1 death. The SR-201 interchange ramps add 113. None of these is in the street ranking. Crashes too small to meet Utah's reporting threshold for property damage are not in UDOT's records, and the data ends August 4, 2025.

Your Rights After a South Salt Lake Collision

Personal injury protection on your own policy pays first: at least $3,000 in medical costs, regardless of fault (Utah Code § 31A-22-307). A claim against the other driver for pain and suffering is available once the injury crosses the § 31A-22-309 threshold, for instance a broken bone, a permanent impairment or disfigurement, or more than $3,000 in medical bills; uninsured motorist claims are exempt from that threshold. When the driver who hit you is never identified, Utah law treats the vehicle as uninsured (§ 31A-22-305(2)(b)). Your recovery is reduced by your own share of fault and is available only if the other parties' combined fault exceeds yours (§ 78B-5-818). Most injury suits have a four-year filing deadline (§ 78B-2-307), but a claim against the city or the state over a road's design or condition requires a written notice of claim within one year (§ 63G-7-402).

The statewide guides explain how fault is proven, how to file a PIP claim and the deadline to bring a case.

Recovering Losses After a South Salt Lake Crash

• Out-of-pocket costs: ambulance and hospital charges, doctor visits, medicine, missed paychecks and the damage to your car.
• Personal losses: pain, sleep and stress problems, and the things you can no longer do the way you did before the crash.
• Long-term needs: future procedures, ongoing therapy, a lower earning capacity and help at home if the injury lasts.

Data, Method and Limits

UDOT Crash_Locations, the state's public crash record set, every crash type from January 1, 2018 to August 4, 2025, when the published records stop. South Salt Lake's current boundary from UGRC is applied to all years. Each crash was assigned to the nearest UGRC Utah Roads segment within 35 meters, with the officer's named road preferred; across all counties that matched the named road about 89% of the time. Serious or fatal means a fatal or suspected serious injury code. Driver flags are what officers recorded, not fault findings. County-level comparisons cover the seven counties in this data. Every city we have ranked this way is listed on our statewide page, Utah’s most dangerous roads.
