Herriman's Most Dangerous Intersections for Pedestrians and Cyclists

The method: begin with the 15 Herriman signals in UDOT's signalized-intersection model for pedestrians and bicycles. Take each crash in UDOT's crash records from the window above that involved a pedestrian or a bicyclist, and assign it to whichever of those signals is closest, provided it is within 250 feet, which is how the Highway Safety Manual defines an intersection crash. A crash UDOT coded Fatal or Suspected Serious Injury is counted here as serious or fatal.

The tally is 13 pedestrian crashes and 7 bicycle crashes. One pedestrian crash was serious or fatal (7.7%, against 16.7% statewide) and none of the bicycle crashes was. Nine of the 15 signals recorded a crash of either kind, seven of them a pedestrian crash, and six recorded none. Four Herriman signals sit on a city line and are listed by UDOT under two cities: two shared with South Jordan and two with Riverton.

A Model That Sees Riders but Few Walkers

For every signal, UDOT's model estimates how many people walk and how many ride through on an average day. In Herriman it gives a rider figure for all 15 signals, from about 8 to about 31 a day. It gives a walker figure for only three: 11800 South at the northbound lanes of SR-85, the Mountain View Corridor (about 377 a day); Rosecrest Road (14400 South) at the same northbound lanes (about 111); and Herriman Parkway (12600 South) at Herriman Main Street (5100 West) (about 27). The other 12 signals carry no pedestrian estimate.

Those 12 are where Herriman's pedestrian crashes were: 12 of the 13, including the city's only serious or fatal crash. Statewide that is the exception. Of UDOT's 1,263 modeled signals, 224 lack a walker estimate, and they hold 152 of 2,105 pedestrian crashes, about 7%. No other Utah city with at least 20 of these crashes is missing the estimate at more than half its signals. A blank in the model is a gap in the data, not proof that nobody walks there, and Herriman has changed quickly: its population went from 21,785 in the 2010 census to 55,144 in 2020.

Herriman Signals With a Pedestrian Crash

Seven Herriman signals recorded a pedestrian crash, so the list stops at seven. Order: pedestrian crashes, then bicycle crashes, then serious or fatal pedestrian crashes; the one tie still left goes to the signal with more estimated foot traffic. Two signals with bicycle crashes only are covered in the next section.

• Daybreak Parkway (11800 South) & Freedom Park Drive (5600 West) — 3 pedestrian crashes, 1 of them serious or fatal, and no bicycle crashes. The only serious or fatal crash at a Herriman signal in the period. UDOT lists the signal under Herriman and South Jordan, and the model has no walker estimate for it.
• 13400 South & 6000 West — 3 pedestrian crashes, none serious or fatal, and no bicycle crashes. The busier road carries about 31,000 vehicles a day by UDOT's estimate; there is no walker estimate.
• 13400 South & 5600 West — 2 pedestrian crashes and 3 bicycle crashes, none serious or fatal. The most bicycle crashes at any Herriman signal. Listed under Herriman and Riverton, with a bus stop nearby.
• Herriman Parkway (12440 South) & Pioneer Street / Mustang Trail Way (6000 West) — 2 pedestrian crashes, neither serious or fatal, and no bicycle crashes. UDOT's model lists a school nearby.
• 11800 South & Mustang Trail Way (6000 West) — 1 pedestrian crash and 1 bicycle crash, none serious or fatal. Listed under Herriman and South Jordan; the model estimates about 18 riders a day.
• 11800 South & SR-85 northbound (Mountain View Corridor) — 1 pedestrian crash, not serious or fatal, and no bicycle crashes. By far the model's busiest walking signal in Herriman, at about 377 people a day, with a school nearby.
• Herriman Main Street (13100 South) & Rosecrest Road (5600 West) — 1 pedestrian crash, not serious or fatal, and no bicycle crashes. A school is nearby, and the busier road carries about 16,000 vehicles a day.

Three east-west roads hold nearly the whole record. The three modeled signals on 13400 South account for 8 of the city's 20 crashes, 11800 South (including the stretch labeled Daybreak Parkway) for 6, and Herriman Parkway for 5. The remaining crash was at Herriman Main Street and Rosecrest Road. Because no signal logged more than three crashes of either kind, the list above separates signals by one or two crashes and should be read that way.

Herriman's Bicycle Crashes

The 7 bicycle crashes fell at four signals, and none was serious or fatal. 13400 South at 5600 West recorded 3. Herriman Parkway (12600 South) at Herriman Main Street (5100 West) recorded 2, with no pedestrian crashes, and Herriman Parkway (12440 South) at Anthem Park Boulevard (5600 West) and 11800 South at Mustang Trail Way recorded 1 each. The model's highest rider estimate in the city, about 31 a day at 11800 South and the Mountain View Corridor, belongs to a signal with no recorded bicycle crash.

Other Estimates in UDOT's Model

Besides walkers and riders, the model attaches vehicle volumes for each road, the number of schools and bus stops close by, and a flag for intersections without lighting. It also predicts a crash figure for each signal, but that prediction came out of a separate UDOT study that gives no time window, so it is not compared with the 2018 to 2025 counts on this page.

Schools appear often: the model lists one near 5 of Herriman's 15 signals, and 3 of those 5 recorded pedestrian crashes. Bus stops are scarce, one each at two signals. None of the 15 is flagged as unlit. One signal is a HAWK pedestrian beacon, at 12100 South and Anthem Park Boulevard, and it recorded no crashes.

Summer Rides and a Busier 2024

Every one of Herriman's bicycle crashes in the complete years 2018 through 2024 happened between June and August: 7 of 7, with 4 in August alone, and all 7 in daylight. Pedestrian crashes were mostly daytime events too. Ten of the 13 happened in daylight and 2 after dark, well below the roughly one-in-three share after dark statewide (718 of 2,105). The one serious or fatal pedestrian crash happened between 6 and 9 a.m.

The pedestrian record also tilts toward recent years. Five of the 13 pedestrian crashes came in 2024, more than in any earlier year, and 2018 had none. With counts this small a single year proves little, but it fits a city whose population more than doubled between the 2010 and 2020 censuses. Friday was the most common day, with 4.

One Serious Crash, Flagged for DUI

The single serious or fatal pedestrian crash at a Herriman signal in this period was flagged for DUI, the only DUI flag among the city's 20 crashes. The other flags are scattered: 3 pedestrian crashes were coded hit and run, 2 were marked for distraction, and teen drivers were noted in 2 pedestrian and 2 bicycle crashes. A flag reflects what the officer recorded at the scene; whether a driver was impaired is decided elsewhere.

Impairment changes one part of the legal picture. Utah ordinarily allows punitive damages only on clear and convincing proof of willful and malicious or knowingly reckless conduct, but that requirement does not apply to a claim arising from a driver's operation of a vehicle while impaired in violation of § 41-6a-502 (Utah Code § 78B-8-201(1)(b)). Whether such a claim is available depends on the evidence of impairment, which is one reason to obtain the police report and any toxicology results early.

City-Street Limits in Herriman

Herriman's main crossings are city streets, so their posted limits come from UGRC's Utah Roads data rather than UDOT's state-route layer. Daybreak Parkway (11800 South), 13400 South and Herriman Parkway are listed at 40 mph at most of their signals, and seven Herriman signals top out at 40. Those seven account for 11 of the 13 pedestrian crashes, including the serious one at Daybreak Parkway and Freedom Park Drive.

The fastest road in the city, the Mountain View Corridor (SR-85), is listed at 55 to 65 mph at its two Herriman signals in UDOT's 2026 data and recorded a single pedestrian crash, at 11800 South. These are current limits that may differ from those in effect at the time of a crash, and with one serious crash Herriman's record cannot say anything about speed and severity; statewide, the serious-or-fatal share does not climb steadily with the posted limit.

What the Count Leaves Out

Twenty crashes over seven and a half years is a small base. Crashes farther than 250 feet from a modeled signal are not counted, so a pedestrian hit at a neighborhood crosswalk, a trail crossing or a school pickup line is outside these numbers. Each crash counts once, at its nearest signal, even when more than one person was hurt. And the record shows where crashes occurred, not who caused them.

After a Crash at a Herriman Signal

What matters most in your case is what the driver did, but the crossing itself is evidence too. Earlier crashes at the same signal can show a hazard was known, and signal timing, crosswalk markings and lighting are recorded by the city or UDOT and can be requested before they change. Where a road's design or a government vehicle is involved, a notice of claim is due well before the ordinary deadline. Our Herriman pedestrian accident and Herriman personal injury pages explain the process, cyclists can start with our guide to Utah bicycle accident claims, and the statewide guides cover how fault is proven, PIP claims and the deadline to sue.

Damages You May Recover

• Costs: medical treatment from the emergency room on, rehabilitation, and income lost while healing or for good.
• Pain and its effects: the injury itself and the parts of daily life it takes away.
• The future: care, procedures and support that will still be needed years from now.

About the Data

Crashes: UDOT's crash records for January 1, 2018 to August 4, 2025, pedestrian- and bicyclist-involved crashes only. Assignment: nearest signal in UDOT's signalized-intersection pedestrian and bicycle safety model, within 250 feet, per the Highway Safety Manual. Serious or fatal: UDOT severity of Fatal or Suspected Serious Injury. Volumes, schools, bus stops, lighting and whether a walker estimate exists: the same UDOT model. Statewide figures: the identical method over all 1,263 modeled signals. Population: U.S. Census Bureau, 2010 and 2020 censuses. Crash months, years and times, lighting and the officers' report flags come from the same UDOT records (months from complete years 2018 through 2024); posted limits come from UGRC's Utah Roads and, for SR-85, UDOT's 2026 state-route speed layer. Every city we have counted this way is listed on our statewide page, Utah’s most dangerous intersections.
