Lehi's Most Dangerous Roads

Every crash UDOT recorded inside Lehi city limits during that span was assigned to a street from the state's road map, using the road named in the officer's report where two streets were close together. I-15, its ramps and the SR-92 interchange ramps are counted in a separate section, and crashes on private property are not ranked. A crash is called serious or fatal when the report lists a death or a suspected serious injury.

UDOT's records put 12,499 crashes inside Lehi. Of those, 4,689 occurred on a freeway or ramp, 137 on private property and 189 could not be placed on a street, leaving 7,484 on Lehi's streets. 135 of the street crashes were serious or fatal, 1.8%, below the 2.6% for streets across the seven counties covered here (Salt Lake, Utah, Davis, Weber, Summit, Cache and Washington), and 19 people died. An injury, including possible injuries, was reported in 31.3% of Lehi street crashes, close to the 32.1% for those counties.

Teen Drivers and Ignored Signals

Officers flagged a teen driver in 2,220 of Lehi's street crashes, 29.7%, against 23.8% across the seven counties. The gap holds for the worst crashes too: a teen driver was involved in 35 of the 135 serious or fatal crashes, 25.9%, against 19.1%. A driver disregarding a signal or sign shows up in 8.8% of all street crashes, only a little above the 7.8% regional figure, but in 31 of the serious or fatal ones, 23.0%, close to double the 12.3% for the seven counties.

Side-impact crashes, the type an ignored light or stop sign tends to produce, account for 59 of Lehi's 135 serious or fatal street crashes, 43.7%, against 35.2% regionally. Among the ten streets ranked below, 2100 North has the highest share of crashes with a signal or sign disregarded, 19.4%, and 1200 East and Ashton Boulevard have the highest teen-driver shares, 38.2% and 34.1%.

Lehi's Streets, Most Crashes First

The order follows the number of crashes UDOT placed on each street within city limits from January 2018 through August 4, 2025. Where two listed streets cross, a crash counts once, on the street the report names, so a junction figure covers one street's crashes there, not every crash at the corner.

• Main Street — 1,108 crashes, 20 serious or fatal, no deaths. 43.0% were rear-end collisions. The junction at 850 East had 185 crashes, far more than any other point on the street; 2300 West is next with 80, 2 of them serious or fatal.
• 2100 North (SR-194) — 675 crashes, 8 serious or fatal, 2 deaths. A driver disregarded a signal or sign in 131 of them, 19.4%, the highest share among these ten. 2300 West (161, 3 serious or fatal) is its busiest junction, and its yearly count rose from 67 in 2018 to 124 in 2024.
• Pioneer Crossing (SR-145) — 671 crashes, 11 serious or fatal, 2 deaths. Rear-end collisions are 63.0% of its crashes, and officers flagged speed in 111, 16.5%, the highest speed share on this list. Mill Pond Road (93), 1100 West (88) and 500 West (83, 3 serious or fatal) lead its junctions. None of its crashes involved a pedestrian or cyclist.
• State Street (US-89) — 387 crashes, 5 serious or fatal, 2 deaths. Side impacts are 49.4% of its crashes, the highest share here. Main Street (66) and 300 West (62) are its busiest junctions, and impairment was flagged in 4 crashes, 2 of them serious or fatal.
• Timpanogos Highway (SR-92) — 363 crashes, 11 serious or fatal, 4 deaths in 4 fatal crashes, the most deaths on any street ranked here. Digital Drive (94, 2 serious or fatal) and 1200 West (62) are its busiest junctions, and 51.0% of its crashes were rear-end collisions.
• Redwood Road (10800 West, SR-68) — 345 crashes, 7 serious or fatal, 3 deaths. 193 of them, more than half, happened at 2100 North. Rear-end collisions are 67.2%, the highest share among these ten, and the street's yearly count climbed from 41 in 2018 to 75 in 2024.
• Triumph Boulevard — 323 crashes, 9 serious or fatal, no deaths. It had 8 crashes in 2018 and has logged between 32 and 58 a year since. Timpanogos (54), Ashton Boulevard (32, 1 serious or fatal) and 2150 North (32) are its busiest junctions.
• Ashton Boulevard — 214 crashes, 2 serious or fatal, no deaths. Its junction with Triumph Boulevard accounts for 71 crashes, a third of its total, and side impacts make up 43.5%.
• Digital Drive — 189 crashes, 4 serious or fatal, no deaths. 97 occurred where it meets Timpanogos Highway. A driver left the scene in 17, 9.0%, the highest hit-and-run share in this list, and a commercial vehicle was involved in 20.
• 1200 East — 186 crashes, 2 serious or fatal, no deaths. A teen driver was involved in 71, 38.2%, the highest teen share among these ten. Red Hawk Drive (21) is its busiest junction.

The ten streets add up to 4,461 crashes, the same number I-15 recorded inside Lehi, plus 79 of the 135 serious or fatal street crashes and 13 of the 19 deaths. Main Street holds 14.8% of the city's street crashes by itself.

Main Street's Count, Timpanogos Highway's Deaths

Main Street leads on serious or fatal crashes as well as total crashes, with 20, yet none of its crashes was fatal. Timpanogos Highway, fifth by crash count, had 4 fatal crashes and the highest serious-or-fatal share among Lehi's fifteen busiest streets, 3.0%. Ranked by serious or fatal crashes, Pioneer Crossing and Timpanogos Highway tie for second with 11, Triumph Boulevard moves from seventh to fourth with 9, and 2100 North drops from second to fifth with 8. Redwood Road's 3 deaths came in a street ranked sixth for crashes.

Stop-and-Go Collisions in a Growing City

Rear-end crashes are the most common type on Lehi's streets, 37.3% against 30.2% across the seven counties, and they dominate the commuter routes: 67.2% of Redwood Road's crashes and 63.0% of Pioneer Crossing's. They rarely cause the worst injuries, accounting for 4 of the 135 serious or fatal crashes. Head-on collisions run the other way, 2.4% of crashes but 14 serious or fatal ones, 10.4%, against 6.9% regionally.

Lehi's street crashes rose from 944 in 2018 to 1,137 in 2024, while the seven-county total fell from 41,657 to 37,964. Serious or fatal crashes went from 9 in 2018 to 27 in 2021 and 28 in 2022, then eased to 14 in 2024. Officers flagged speed in 11.5% of crashes (8.4% regionally) and a distracted driver in 12.7% (9.8%), and snow, ice or slush covered the road in 7.2% (5.9%). Hit-and-runs were less common than elsewhere, 4.0% against 8.6%.

I-15: More Than a Third of Lehi's Crashes

Freeways and ramps account for 4,689 of Lehi's 12,499 crashes, 37.5%. I-15 itself had 4,461, with 65 serious or fatal and 4 deaths, and the SR-92 interchange ramps had 199, 5 of them serious or fatal. Those crashes stay out of the street ranking above. UDOT's records also leave out crashes below Utah's property-damage reporting threshold, and they stop on August 4, 2025.

After a Lehi Crash: Coverage and Deadlines

Your own personal injury protection is the first payer, with at least $3,000 for medical expenses no matter who was at fault (Utah Code § 31A-22-307). A claim against the other driver for pain and other general damages requires an injury over the § 31A-22-309 threshold, such as a fracture, permanent impairment or medical bills above $3,000; uninsured motorist claims are exempt from that threshold. If the driver who hit you is never identified, the law treats the vehicle as uninsured (§ 31A-22-305(2)(b)). When the driver was a minor, Utah generally imputes the minor's liability to the adult who signed the license application, up to the minimum policy limits, unless the required insurance was in force (§ 53-3-211). Your share of fault reduces your award, and you recover only if the other parties' fault is greater than yours (§ 78B-5-818). The general deadline for an injury suit is four years (§ 78B-2-307); a claim that a city or state road contributed requires a written notice of claim within one year (§ 63G-7-402). For more, see our Lehi car accident and Lehi personal injury pages, Lehi’s most dangerous intersections, and the guides to how fault is proven, filing a PIP claim and filing deadlines.

Losses a Lehi Claim Can Cover

• Out-of-pocket costs: ambulance, hospital and therapy bills, medication, lost income, reduced future earnings, and vehicle repair or replacement.
• Human losses: pain, sleep and mood problems after the crash, and time away from the people and pursuits that matter to you.
• Future care: treatment still to come, long-term therapy, and support at home if an injury does not fully heal.

Behind Lehi's Figures

Records: UDOT's public Crash_Locations data for Utah County, all crash types, January 1, 2018 through August 4, 2025, the last date in the published series. City limits come from UGRC's current municipal boundary map and are used for every year. Each crash was matched to the nearest UGRC Utah Roads segment within 35 meters, favoring the road the officer named; across the whole data set that match agreed with the report in 89% of crashes. Serious or fatal covers crashes coded fatal or suspected serious injury. Teen driver, speed, distraction and similar flags are officer entries, not findings of fault. Regional comparisons are to the seven counties in this data. Every city we have ranked this way is listed on our statewide page, Utah’s most dangerous roads.
