American Fork's Most Dangerous Intersections for Pedestrians and Cyclists

Each figure here is either a count from UDOT's crash records or an estimate from UDOT's model, and the two are kept apart. The model supplies the list of signalized intersections, 16 of them in American Fork. Every crash in the records involving a pedestrian or bicyclist was tied to the closest of those signals if it lay within 250 feet, which is where the Highway Safety Manual draws the line for an intersection crash. A crash UDOT coded as Fatal or Suspected Serious Injury is called serious or fatal on this page.

Over those seven-plus years the city's signals logged 22 pedestrian crashes and 7 bicycle crashes, 29 in total. Four pedestrian crashes (18.2%) were serious or fatal; none of the bicycle crashes were. Nine signals had at least one pedestrian crash, six had at least one bicycle crash, and four had no crash of either kind.

Traffic Volume and the Crash Count Line Up

Sort American Fork's signals by the traffic UDOT estimates on the busier road and a clear break appears around 27,000 vehicles a day. Seven signals sit above it: Main Street at 100 East and at 300 West, State Street at 500 East, 900 West and 1100 East, Pacific Drive at US-89, and the junction on the west side where Main Street meets State Street. Those seven hold 18 of the 22 pedestrian crashes. The nine signals below the break, on roads estimated at 20,500 vehicles a day or less, hold the other 4.

Foot traffic points the same way. UDOT's model credits five signals with the most daily walkers: Main Street at 100 East (about 273), State Street at 500 East (213), State Street at 900 West (141), Pacific Drive (128) and State Street at 1100 East (121). Those five recorded 16 of the 22 pedestrian crashes. The exception is the busiest crossing of all, Main Street's junction with State Street, where the busier road is estimated at 38,000 vehicles a day and the model estimates about 83 people walk through daily. It recorded no crash of either kind.

American Fork's Signals With a Pedestrian Crash

Nine American Fork signals had a pedestrian crash from January 2018 through August 4, 2025, and all nine are listed here, ordered by pedestrian crashes. A tie goes to the signal with more bicycle crashes, then to the one with more serious or fatal pedestrian crashes, then to the one with more estimated daily foot traffic. Vehicle volumes and walker counts are UDOT model estimates.

• Main Street (US-89) & 100 East (SR-74) — 4 pedestrian crashes (1 serious or fatal) and 1 bicycle crash. It has the most estimated foot traffic of any American Fork signal, about 273 people a day, and two bus stops nearby.
• State Street (US-89) & 1100 East (North County Boulevard / SR-129) — 4 pedestrian crashes, 1 serious or fatal, and no bicycle crashes. Two bus stops sit nearby, and the busier road carries about 28,000 vehicles a day by UDOT's estimate.
• State Street (US-89) & 900 West — 3 pedestrian crashes and 1 bicycle crash, none serious or fatal. About 141 people walk through daily by estimate, the third-most in the city.
• State Street (US-89) & 500 East (SR-180) — 3 pedestrian crashes, none serious or fatal, and no bicycle crashes. The busier road is estimated at about 31,000 vehicles a day, second only to the Main Street and State Street junction.
• Main Street (US-89) & 300 West — 2 pedestrian crashes, 1 of them serious or fatal, and no bicycle crashes. At about 27,000 vehicles a day on the busier road, it is the lightest of the seven high-volume signals.
• Pacific Drive & US-89 — 2 pedestrian crashes, neither serious or fatal, and no bicycle crashes. UDOT estimates about 128 people on foot and 29,000 vehicles on the busier road each day.
• 300 North & 100 East (SR-74) — 2 pedestrian crashes, neither serious or fatal, and no bicycle crashes. UDOT's model lists two schools nearby.
• 100 North & 100 East (SR-74) — 1 pedestrian crash, serious or fatal, and 2 bicycle crashes, the most bicycle crashes at any American Fork signal. It sits one block north of Main Street on the same street as the city's top location.
• 700 North & 1100 East (North County Boulevard / SR-129) — 1 pedestrian crash, not serious or fatal, and no bicycle crashes. A school is nearby, and the busier road carries about 11,000 vehicles a day by estimate.

Downtown carries more of the severity than the totals suggest. Four listed signals lie within about 3,000 feet of Main Street and 100 East: that crossing itself, Main Street at 300 West, and 100 East at 100 North and at 300 North. They account for 9 of the 22 pedestrian crashes and 3 of the 4 serious or fatal ones. The fourth serious crash was at State Street and 1100 East, on the city's east side.

Bicycle Crashes in American Fork

Seven bicycle crashes over more than seven years is a small number, and none was serious or fatal. They fell at six signals, with 100 North and 100 East the only one to record 2. Unlike the pedestrian crashes, most were away from the heaviest traffic: five of the seven happened at signals below the 27,000-vehicle break, including two on North County Boulevard, at 50 South and at 300 North, and one at 1120 North and 100 East.

How UDOT's Estimates Fit In

UDOT's safety model goes beyond a list of signals. For each one it estimates daily walkers and riders and the traffic on both roads, and it notes nearby schools and bus stops and whether the crossing is lit. Those fields describe exposure, and this page uses them that way. The model's predicted crash figures are another matter: they come from a separate, undated exercise, so they are not compared with the January 2018 to August 2025 counts here.

Two of American Fork's signals exist mainly for people on foot: a HAWK beacon on North County Boulevard at 150 North that UDOT's data labels for the hospital (American Fork Hospital is at 170 North 1100 East), and a pedestrian crossing on 1120 North labeled for the junior high (American Fork Junior High is at 20 West 1120 North). Neither recorded a crash. UDOT's model has no walker estimate for either, which says more about the model than about the crossings. No American Fork signal is flagged as unlit.

American Fork's Crash Times and Light

American Fork's 22 pedestrian crashes are spread across the day rather than bunched in one window: 4 between 6 and 9 a.m., 7 between 9 a.m. and 3 p.m., 6 between 3 and 7 p.m., 4 between 7 p.m. and midnight, and 1 after midnight. Fifteen happened in daylight and 5 after dark. Yet 2 of the 4 serious or fatal crashes were among those 5 after dark, so darkness accounts for half of the city's worst outcomes while accounting for under a quarter of its crashes.

Wet roads figure more here than at most signals. Four of the 22 pedestrian crashes happened on a wet road surface, 18.2%, against 10.6% statewide. By weekday, Friday logged the most (6) and Sunday none.

Teen Drivers in American Fork's Crash Reports

One driver flag stands out in American Fork. Six of its 22 pedestrian crashes involved a teenage driver, 27.3%, the highest share of any Utah city with at least 20 pedestrian crashes counted this way and roughly three times the 8.8% across all modeled signals. None of those six was serious or fatal. The other flags are rare: one hit-and-run, one distracted driver, one driver who disregarded a signal or sign, and two crashes involving an older driver, one of them serious or fatal. No bicycle crash in the city carried a hit-and-run, distraction or DUI flag.

Whoever was driving, the first money for medical care usually comes from personal injury protection. Utah's PIP statute covers a pedestrian injured in Utah in an accident involving the insured vehicle (Utah Code § 31A-22-308(3)(b)), with at least $3,000 per person for medical expenses (§ 31A-22-307(1)(a)). It also pays up to $20 a day, for as many as 365 days, toward household services the injured person can no longer do (§ 31A-22-307(1)(b)(ii)).

State Street at 45 mph, Main Street at 30

Speed limits split American Fork's list into two groups. Three State Street signals, at 1100 East, 900 West and 500 East, have a street posted 45 mph; together they account for 10 of the 22 pedestrian crashes but only 1 of the 4 serious or fatal ones. Five listed signals top out at 30 or 35 mph: Main Street at 100 East and 100 North at 100 East (30), and Main Street at 300 West, Pacific Drive at US-89 and 300 North at 100 East (35). They account for 11 pedestrian crashes and 3 of the 4 serious or fatal ones.

UDOT's sidewalk inventory, which covers state routes only, flags absent or broken sidewalk within about 500 feet of State Street at 1100 East, the second signal on the list, with 4 pedestrian crashes, one of them serious or fatal. The limits given are UDOT's current state-route limits and the city-street limits in UGRC's Utah Roads data, and may not match what was posted at the time of an older crash.

What the Counts Cannot Show

The window closes at 250 feet. A person struck mid-block on State Street, in a driveway, in a store parking lot or at a crosswalk without a signal is not in these figures. No crash is counted at two signals. A count is of crashes, not of the people hurt in them. With single-digit counts at every signal, one crash can reorder the list, and none of this decides who was at fault.

When a Driver Hits You at One of These Signals

Prior crashes at the same signal are evidence of notice: they make it harder to argue that the danger came out of nowhere, especially where the timing, markings or lighting of the crossing is in question. Those records sit with American Fork City or UDOT and can be requested. A claim against a government entity over a crossing's design must also meet the Governmental Immunity Act's notice deadline, which is far shorter than the usual window. Our American Fork pedestrian accident and bicycle accident pages describe how a claim moves forward, and our statewide guides explain how fault is proven, how PIP claims are filed and the filing deadline.

Losses a Claim Covers

• Costs: emergency treatment, follow-up visits and rehab, the paychecks lost during recovery, and a smaller income down the road if the injury limits work.
• Quality of life: physical pain, disrupted sleep and routines, and the loss of walking or riding as something ordinary.
• What lies ahead: treatment that is still needed, from surgery to long-term therapy and help at home.
