Salt Lake City's Most Dangerous Roads

This page ranks streets, not intersections. Every crash in UDOT's records inside Salt Lake City limits from January 1, 2018 through August 4, 2025 was placed on the street it happened on, using the state's road map and the road named in the officer's report. Interstate crashes and ramp crashes are tallied on their own, as are crashes in private lots. A crash counts as serious or fatal when the report lists someone killed or someone with a suspected serious injury.

The records hold 32,764 crashes inside the city. Of those, 11,469 happened on I-15, I-80, I-215 and their ramps, 398 in private lots, 305 could not be tied to a specific street, and 20,592 occurred on the rest of the city's roads, the set this page ranks. On those roads 541 crashes were serious or fatal and 107 people died. Some injury, including a possible injury, was reported in 42.9% of them, compared with 32.1% across the seven counties in this data (Salt Lake, Utah, Davis, Weber, Summit, Cache and Washington).

Two Roads, a Fifth of the Deaths

Redwood Road (1700 West, SR-68) recorded 1,173 crashes, more than any other street in Salt Lake City, and State Street (US-89) recorded 952. Between them they hold 93 of the city's 541 serious or fatal crashes (17.2%) and 24 of its 107 road deaths (22.4%). Both are state routes; UDOT's traffic estimates reach about 35,000 vehicles a day on Redwood and about 36,000 on State.

They hurt people in different ways. On State Street, 22 of the 45 serious or fatal crashes involved a pedestrian. On Redwood Road, collisions in which one vehicle strikes the side of another made up 43.1% of all crashes, and 10 of the serious or fatal crashes involved a motorcycle. Redwood also had 159 crashes in which a driver left the scene, the most of any street in the city's top fifteen.

The Ten Streets With the Most Crashes

Ranked by crashes recorded on each street inside city limits from January 2018 through August 4, 2025. A crash where two of these streets meet is counted once, on the street the officer's report names. The cross streets shown are the busiest junctions along each road.

• Redwood Road (1700 West, SR-68) — 1,173 crashes, 48 serious or fatal, 14 deaths. Its busiest junctions are 1700 South (93 crashes), 700 North (78) and 200 South (74).
• State Street (US-89) — 952 crashes, 45 serious or fatal, 10 deaths. 2100 South (89) and 1300 South (81) lead its junctions, and 79 of its crashes involved a pedestrian.
• 2100 South — 791 crashes, 16 serious or fatal, 4 deaths. The worst stretch is on the west side, at 700 West (52), 600 West (47) and 400 West (46).
• 700 East (SR-71) — 671 crashes, 16 serious or fatal, 3 deaths. Rear-end crashes were 33.7% of the total, and UDOT's volume estimate of up to 51,000 vehicles a day is the highest of these ten roads. Its busiest junction is 2100 South (62).
• 300 West — 611 crashes, 15 serious or fatal, 4 deaths. 600 South and 500 South tie as its busiest junctions at 54 crashes each, and 45 crashes involved a pedestrian.
• 400 South — 598 crashes, 20 serious or fatal, 5 deaths. 300 West (44) and 700 East (41) are its busiest junctions; 9 of the serious or fatal crashes involved a pedestrian.
• 900 West — 546 crashes, 15 serious or fatal, 3 deaths. A driver left the scene in 14.8% of them, the highest hit-and-run share among these ten, and rear-end crashes (33.3%) outnumbered side-impact crashes (31.5%).
• West Temple (100 West) — 526 crashes, 14 serious or fatal, 3 deaths. Side-impact crashes were 46.6%, the highest share among these ten, and 900 South alone accounts for 82 crashes.
• California Avenue (1330 South) — 512 crashes, 18 serious or fatal, 4 deaths. Its junction with Redwood Road had 61 crashes, and 9 of its 18 serious or fatal crashes were side impacts.
• Foothill Drive (SR-186) — 502 crashes, 11 serious or fatal, 1 death. Rear-end crashes were 45.8%, the highest share among these ten; 1300 South and Stringham Avenue tie at 48 crashes each.

Together the ten hold 6,882 crashes, a third of the 20,592 on the city's non-freeway roads. They hold a larger share of the harm: 218 of the 541 serious or fatal crashes (40.3%) and 51 of the 107 deaths (47.7%). The data places crashes on 644 different streets in Salt Lake City; ten of them account for nearly half of the people killed.

A Different Order for Serious Crashes

Sort by serious or fatal crashes and North Temple Street climbs from 14th to 3rd: 411 crashes, 21 serious or fatal, 6 deaths. That 5.11% share is the highest among the city's fifteen busiest streets. 400 South moves to 4th with 20 and California Avenue to 5th with 18. Foothill Drive drops out of the top ten. Its most common crash is the rear-end collision, and citywide rear-end crashes were 24.6% of all crashes but only 8.3% of the serious or fatal ones.

Crash Types and the People Hurt Worst

Side-impact crashes are the most common type on the city's streets (33.9%), followed by rear-end crashes (24.6%). More than half of the serious or fatal crashes, 283 of 541, fall in the group UDOT reports as single-vehicle or not applicable, which includes a vehicle striking a pedestrian, a cyclist or a fixed object. Pedestrians were involved in 4.8% of crashes but 31.6% of the serious or fatal ones, more than double the 15.1% across the seven counties. Motorcyclists were in 2.3% of crashes and 18.3% of the serious ones.

Officers recorded a driver leaving the scene in 11.2% of the city's crashes, against 8.6% across the seven counties, and a driver disregarding a signal or sign in 11.3% (7.8%). Impairment was flagged in 2.4% of crashes but 9.1% of the serious or fatal ones. Crashes peak in the 5 p.m. hour, and Sunday has the fewest. In 2020 the city recorded 2,251 crashes, about 30% fewer than the 3,196 of 2019, yet 75 were serious or fatal, more than 2019's 65.

The Interstates, Counted on Their Own

I-15, I-80, I-215 and their ramps account for 11,469 crashes inside city limits, 35.0% of the total. I-15 alone had 5,016, with 62 serious or fatal and 18 deaths; I-80 had 3,520, with 51 serious or fatal and 8 deaths; I-215 had 2,265, with 29 serious or fatal and 7 deaths. A smaller share of freeway crashes is serious: 1.24% on I-15 against 2.63% on the city's other roads. Rear-end collisions were 41.1% of I-15's crashes, and officers flagged speed in 38.5%. Highway 201 (SR-201), an expressway, had 788 crashes, 11 of them serious or fatal; it is included in the 20,592 but left out of the street ranking. Crashes below Utah's reporting threshold for property damage are not in the data, and nothing after August 4, 2025 is.

If You Were Hurt on One of These Roads

Your own personal injury protection pays first, at least $3,000 in medical expenses no matter who caused the crash (Utah Code § 31A-22-307). A claim against the other driver for pain and other general damages requires an injury past the threshold in § 31A-22-309, such as a bone fracture, a permanent impairment or more than $3,000 in medical expenses, and that threshold does not apply to an uninsured motorist claim. When a driver leaves the scene and is never identified, Utah treats the vehicle as uninsured (§ 31A-22-305(2)(b)), so your own UM coverage can respond. Your share of fault reduces what you recover, and you recover only if the others' fault exceeds yours (§ 78B-5-818). Most injury suits must be filed within four years (§ 78B-2-307), but a claim against the city or the state, including one that a road was unsafe, needs a written notice of claim within one year (§ 63G-7-402). Our Salt Lake City car accident page explains how these claims proceed, and Salt Lake City’s most dangerous intersections covers the signals where people on foot and on bikes are hit. See also how fault is proven, how to file a PIP claim and the deadline to bring a case.

What a Claim Can Cover

• Costs you can add up: the ambulance, the hospital, follow-up treatment, the paychecks missed while recovering, a reduced ability to earn later, and the repair or replacement of your vehicle.
• Harms without a receipt: physical pain, lost sleep and mobility, and the strain an injury puts on daily life and family.
• Costs still ahead: surgery or therapy a doctor expects you to need, and help at home if the injury is permanent.

Sources and Method

Crashes: UDOT's public crash records (Crash_Locations), all crash types, January 1, 2018 through August 4, 2025, where the public series ends. City limits: the state's municipal boundary map from UGRC, applied to every year. Streets: each crash was matched to the nearest segment of UGRC's Utah Roads map within 35 meters, favoring the road named in the officer's report; in a check of the whole dataset the match agreed with the report's road about nine times in ten. Serious or fatal: reported as fatal or suspected serious injury. Traffic volumes are UDOT estimates for state routes and come from different years. Driver and crash flags record what the investigating officer noted, not findings of fault. Comparisons are to the seven counties covered by this data. Every city we have ranked this way is listed on our statewide page, Utah’s most dangerous roads.
