Lehi's Most Dangerous Intersections for Pedestrians and Cyclists

Nothing on this page is a risk score. Each figure is either a crash count or a labeled UDOT estimate. The list of signals comes from UDOT's pedestrian and bicycle safety model, which includes 25 in Lehi. Every crash in UDOT's records that involved someone walking or riding a bike was assigned to the closest of those signals, as long as it was no more than 250 feet away; the Highway Safety Manual treats crashes inside that radius as intersection crashes. A crash UDOT coded as Fatal or Suspected Serious Injury appears here as serious or fatal.

Those rules yield 15 crashes involving pedestrians and 15 involving cyclists, 29 separate crashes in all because one involved both. Four of the pedestrian crashes (26.7%) and two of the bicycle crashes (13.3%) were serious or fatal. Fifteen of the 25 signals recorded at least one crash of either kind, and the remaining ten recorded none.

Main Street Holds Most of the Record

Five of Lehi's modeled signals sit on Main Street, running west from State Street past 850 East, 500 East and Center Street to 1700 West. Together they hold 9 of the city's 15 pedestrian crashes, 6 of its 15 bicycle crashes, and both of its serious or fatal bicycle crashes. The city's top location is at the east end of that stretch: Main Street (SR-73) at State Street (US-89), with 3 pedestrian and 2 bicycle crashes. It is the only Lehi signal where a serious or fatal crash of each kind was recorded.

Pioneer Crossing tells the other half of the story. The highway opened in 2010, and its six modeled signals in Lehi sit where UDOT estimates the busier road carries 24,000 to 42,000 vehicles a day, against 9,000 to 25,000 at the Main Street signals. Yet those six recorded 2 pedestrian crashes, neither serious or fatal, and no bicycle crashes. UDOT's model also estimates far fewer people on foot there: 14 to 39 a day at the Pioneer Crossing signals, compared with 46 to 136 along Main Street. In Lehi the crash count follows the places people walk and ride more closely than it follows vehicle volume.

Every Lehi Signal With a Pedestrian Crash

Exactly ten Lehi signals recorded a pedestrian crash between January 2018 and August 4, 2025, so the list below is all of them, ordered by pedestrian crashes. Where counts tie, the signal with more bicycle crashes goes first, then the one with more serious or fatal pedestrian crashes, then the one UDOT's model credits with more daily foot traffic. Volume and foot-traffic figures are model estimates, not counts.

• Main Street (SR-73) & State Street (US-89) — 3 pedestrian crashes (1 serious or fatal) and 2 bicycle crashes (1 serious or fatal). UDOT's model puts roughly 92 people on foot through this signal each day.
• Main Street (SR-73) & 850 East — 3 pedestrian crashes and 1 bicycle crash, none serious or fatal. By UDOT's estimate the busier road here carries about 25,000 vehicles a day, the most at any Main Street signal.
• Main Street & Center Street — 2 pedestrian crashes and 2 bicycle crashes, one of the bicycle crashes serious or fatal. Its busier road is estimated at about 9,000 vehicles a day, among the lightest volumes on this list.
• 2100 North (SR-85) & 2300 West — 1 pedestrian crash and 2 bicycle crashes, none serious or fatal. At about 132 people a day, it has the highest estimated foot traffic of any signal on this list, and UDOT's model notes a school nearby.
• State Street (US-89) & 300 West — 1 pedestrian crash and 2 bicycle crashes, none serious or fatal. Two bus stops are nearby, and the model estimates about 9 riders a day, more than at any other signal on this list.
• Timpanogos Highway (SR-92 / 11000 North) & Traverse Mountain (Triumph) — 1 pedestrian crash, serious or fatal, and 1 bicycle crash. The busier road carries about 25,500 vehicles a day by UDOT's estimate.
• Main Street & 1700 West — 1 pedestrian crash, serious or fatal, and no bicycle crashes. It is the westernmost of the five Main Street signals, with about 46 people on foot a day by estimate.
• 900 North & 1200 East — 1 pedestrian crash, serious or fatal, and no bicycle crashes. UDOT's model has no walker estimate for this signal, even though a crash here was serious or fatal.
• Pioneer Crossing (SR-145) & 2300 West (9550 West) — 1 pedestrian crash, not serious or fatal, and no bicycle crashes, on a road estimated at about 24,000 vehicles a day.
• Pioneer Crossing (SR-145) & 1100 West / 8730 West — 1 pedestrian crash, not serious or fatal, and no bicycle crashes. Estimated foot traffic is about 14 people a day.

Seven of the ten listed signals have one pedestrian crash apiece over more than seven and a half years, so the lower half of the list is separated by tie-breaks rather than by any real difference in danger. The four serious or fatal pedestrian crashes fell at four separate signals: two on Main Street, one on Timpanogos Highway and one at 900 North and 1200 East.

Where Lehi's Cyclists Were Hit

Lehi's 15 bicycle crashes reached 11 signals, and no signal had more than 2. Main Street again leads, with 6 of the 15 and both of the serious or fatal ones, one at State Street and one at Center Street. Away from Main Street they come one or two at a time: 2100 North and 2300 West, State Street and 300 West, two signals on Timpanogos Highway, and Club House Drive at Ashton Boulevard among them.

Reading UDOT's Exposure Estimates

For each signal, UDOT's model estimates how many people walk and ride through on an average day, how many vehicles travel the two roads, how many schools and bus stops sit nearby, and whether the crossing is lit. Those estimates help explain where people are exposed. The model also produces a predicted crash figure for every signal, but it was not built for the January 2018 to August 2025 period, so this page leaves it out rather than set it against the counts.

In Lehi the estimates explain part of the map and leave part unexplained. The signal with the most estimated foot traffic in the city, Club House Drive (SR-92) at Ashton Boulevard at about 266 people a day, recorded no pedestrian crashes and a single bicycle crash. Main Street at 500 East, second at about 136, also had no pedestrian crash. Main Street at 850 East, estimated at about 118, had 3. None of Lehi's 25 modeled signals is flagged as unlit. With one to three crashes per signal, differences like these may reflect chance as much as a pattern.

Lehi After Dark: Few Crashes, Severe Outcomes

Lehi's pedestrian crashes are few enough that each one shows in the pattern. Ten of the 15 happened in daylight, and only one of those ten was serious or fatal. Three happened after dark, and all three were serious or fatal. Mornings stand out too: 4 of the 15 came between 6 and 9 a.m., and 2 of those 4 were serious or fatal. With counts this small these are observations about individual crashes rather than a trend, but they are what Lehi's records show.

Lehi's bicycle crashes keep a different calendar. Six of the 15 happened on a Saturday, while statewide only about one bicycle crash in eight at a modeled signal falls on that day (13.1%). Over the complete years 2018 through 2024, 9 of 13 came between May and July.

What Lehi's Crash Reports Flag

The driver flags on Lehi's reports are sparse. Three of the 15 pedestrian crashes were hit-and-runs, one of them serious or fatal. One involved an older driver, also serious or fatal; one involved a teenage driver; one was flagged for a driver disregarding a signal or sign. None was flagged for distraction, DUI or speeding. Among the 15 bicycle crashes, the only flag that appears is a teenage driver, once.

Two parts of Utah's uninsured-motorist statute matter most to people hit while walking or riding. A vehicle that causes a crash and leaves without being identified counts as an uninsured motor vehicle (Utah Code § 31A-22-305(2)(b)), and a covered person hit as a pedestrian by an uninsured vehicle may also recover under one other policy in which they are a covered person (§ 31A-22-305(8)(b)). If an unidentified vehicle caused the crash without touching the injured person, the bar is higher: its existence must be shown by clear and convincing evidence that is more than the injured person's own testimony (§ 31A-22-305(6)). A witness, a dash camera or nearby video can decide that question.

Posted Limits on Lehi's Listed Signals

Lehi's listed signals sit on fast roads. UDOT's current speed-limit data lists 50 mph for SR-73 at State Street and at 850 East, the two signals with the most pedestrian crashes, and 50 mph for Pioneer Crossing at 2300 West and at 1100 West. State Street at 300 West and Timpanogos Highway at Traverse Mountain are posted 45, three listed signals top out at 40, and only 900 North at 1200 East, where both streets are 25 mph, is slower. Ten of Lehi's 15 pedestrian crashes, and 2 of its 4 serious or fatal ones, happened at signals with a street posted 45 mph or more; statewide that share is 21.6%.

The posted limit did not decide who was badly hurt. Lehi's four serious or fatal pedestrian crashes happened at signals listed at 50, 45, 40 and 25 mph, and the Pioneer Crossing signals, all listed at 45 or 50, recorded only 2 pedestrian crashes between them. State-route limits are UDOT's current figures and city-street limits come from UGRC's Utah Roads data, so either may differ from what was posted when an older crash happened.

Limits of These Counts

A crash more than 250 feet from every modeled signal is not here, which leaves out people hit at unsignalized crossings, along the long gaps between signals on Pioneer Crossing, in driveways and in parking lots. Each counted crash belongs to one signal only. The totals count crashes rather than injured people, and one crash can hurt several. Nothing here assigns fault: a count shows where a crash was recorded, not who caused it.

After a Crash at a Lehi Signal

A crossing's history can matter to a claim. Earlier collisions at the same spot bear on whether a hazard was known, and the design records behind a crossing, such as signal timing, crosswalk markings and lighting, are kept by Lehi City or UDOT and can be requested. A claim that a government body designed or maintained a crossing badly also carries its own notice deadline under Utah's Governmental Immunity Act, much shorter than the ordinary limit. Our Lehi pedestrian accident and bicycle accident pages explain how these claims proceed, and the statewide guides cover how fault is proven, filing a PIP claim and the deadline to sue.

What Can Be Recovered

• Money losses: ambulance and hospital bills, surgery and therapy, wages missed while healing, and reduced earning power if the injury lasts.
• Human losses: the pain, the sleep it costs, and a walk or ride that no longer feels safe to take.
• Future losses: care still to come, from a later surgery to help at home when recovery stops short.

Sources and Method

Counts come from UDOT's crash records for January 1, 2018 through August 4, 2025, limited to crashes involving a pedestrian or bicyclist and matched to the nearest modeled signal within 250 feet, the Highway Safety Manual's intersection distance. Serious or fatal means a UDOT severity code of Fatal or Suspected Serious Injury. The signal list and the estimates of walkers, riders, vehicles, schools, bus stops and lighting come from UDOT's signalized-intersection pedestrian and bicycle safety model. Statewide percentages apply the same method to all 1,263 signals in that model. The timing, lighting and driver-flag figures come from the same UDOT crash records, with months counted over the complete years 2018 through 2024; posted limits come from UDOT's 2026 state-route speed data and UGRC's Utah Roads. Every city we have counted this way is listed on our statewide page, Utah’s most dangerous intersections.
