St. George's Most Dangerous Roads

Every crash UDOT recorded inside St. George city limits during that period was assigned to a street, using the state's road map together with the road the investigating officer wrote down. Crashes on I-15 and its ramps are counted separately, and so are crashes in private parking lots. Serious or fatal means the report listed a death or a suspected serious injury.

UDOT's records place 13,974 crashes in St. George. I-15 and the interchange ramps account for 1,133, private property for 263, and 84 could not be matched to a street. That leaves 12,494 crashes on the city's other roads, and those are the ones ranked here. 309 of them were serious or fatal, and 42 people died. Someone was reported hurt, counting possible injuries, in 33.7% of those crashes, a little above the 32.1% across the seven counties in this data (Salt Lake, Utah, Davis, Weber, Summit, Cache and Washington).

The Busiest Crash Street and the Deadliest Are Different Roads

Bluff Street (SR-18) is third in St. George by number of crashes, but no other ranked road comes close to its toll: 35 serious or fatal crashes, 7 of them fatal, and 8 people killed, nearly one in five of the city's 42 road deaths. River Road logged 183 more crashes than Bluff Street, along with 25 serious or fatal ones, and no deaths. Volume and harm part ways here: a road can produce a steady stream of fender-benders without the crashes that end lives.

Serious crashes also became more common. In 2018 the city's streets saw 25 serious or fatal crashes; from 2021 through 2024 the yearly count ran between 46 and 50. Total crashes rose far less over the same years, from 1,593 in 2018 to 1,716 in 2024, about 8%. Bluff Street followed the same arc, with 19 of its 35 serious or fatal crashes in 2021 and 2022 alone.

St. George Streets Ranked by Reported Crashes

Each street is ranked by the crashes recorded on it inside city limits from January 2018 through August 4, 2025. Where two of these roads cross, a crash is counted once, on whichever road the officer's report names. The cross streets listed are where each road's own crashes cluster.

• River Road — 1,119 crashes, 25 serious or fatal, no deaths. Side-impact crashes (39.9%) edge out rear-end crashes (35.0%). Its crashes gather at 700 South (88), Riverside Drive (86) and 100 South (84), and 11 of its 25 serious or fatal crashes involved a motorcycle.
• St. George Boulevard (SR-34) — 941 crashes, 11 serious or fatal, 1 death. Nearly half (49.5%) were rear-end collisions, and the crossing at 1000 East alone accounts for 150 of them.
• Bluff Street (SR-18) — 936 crashes, 35 serious or fatal, 8 deaths. Its busiest junctions are 700 South (58), Sunset Boulevard (57) and 100 South (55); a motorcycle was involved in 10 of the serious or fatal crashes.
• Riverside Drive — 620 crashes, 13 serious or fatal, no deaths. Side-impact crashes make up 45.6%, and its junction with River Road accounts for 130 of them.
• Red Hills Parkway — 564 crashes, 18 serious or fatal, 1 death. A quarter (25.0%) fall in UDOT's single-vehicle or not-applicable group, the highest share among these ten, and officers flagged impairment in 42 crashes (7.4%), also the highest share among them. 900 East (70) and 1000 East (62) are its busiest junctions.
• Sunset Boulevard (SR-8) — 557 crashes, 21 serious or fatal, 4 deaths. Dixie Drive (99 crashes, 4 serious or fatal) and Westridge Drive (61 crashes, 4 serious or fatal) are where its worst crashes concentrate.
• Dixie Drive — 525 crashes, 12 serious or fatal, 3 deaths. A driver left the scene in 34 of them (6.5%), the highest hit-and-run share among these ten roads. 600 West (58) and Sunset Boulevard (42) are its busiest junctions.
• Red Cliffs Drive — 522 crashes, 21 serious or fatal, 2 deaths. At 4.0%, it has the highest serious-or-fatal share of the city's fifteen busiest streets, and officers flagged a driver disregarding a signal or sign in 13.2% of its crashes. 92 of its crashes, 5 of them serious or fatal, were at Mall Drive.
• 700 South — 443 crashes, 4 serious or fatal, 1 death. Half (50.1%) were rear-end crashes and distraction was flagged in 72, the highest shares of either among these ten. Its serious-or-fatal share, 0.9%, is the lowest on the list.
• Mall Drive — 408 crashes, 9 serious or fatal, 1 death. Side impacts are 49.3% of its crashes, more than on any other road here; Riverside Drive (58) and Red Cliffs Drive (54) are its busiest junctions.

The ten roads above carry 6,635 crashes, 53.1% of the 12,494 on St. George's non-freeway streets, along with 169 of the 309 serious or fatal crashes and 21 of the 42 deaths. The other 21 deaths are spread across the remaining 523 streets the data places crashes on.

Where Serious Injuries Pile Up

Ranked by serious or fatal crashes instead, the order shifts. Bluff Street leads with 35, River Road follows with 25, and Sunset Boulevard and Red Cliffs Drive tie at 21, ahead of Red Hills Parkway at 18. St. George Boulevard falls from second to eighth: only 11 of its 941 crashes, 1.2%, were serious or fatal, a pattern that fits a road where half the collisions are rear-end impacts in slow traffic.

Who Is on the Road When It Goes Wrong

Side-impact crashes are the most common type on St. George streets (37.5%, against 32.6% across the seven counties), with rear-end crashes close behind (30.5%). Rear-end crashes rarely cause the worst injuries, though: they account for 14 of the 309 serious or fatal crashes. The largest share, 144, sits in the group UDOT reports as single-vehicle or not applicable, which includes vehicles striking a pedestrian, a cyclist or a fixed object. Motorcycles were in 3.1% of crashes but 85 of the serious or fatal ones (27.5%, against 21.7% across the seven counties), and pedestrians were in 1.8% of crashes but 54 of the serious or fatal ones.

The crash reports describe an older population behind the wheel. An older driver was involved in 25.7% of crashes, compared with 14.9% across the seven counties, and a teen driver in 30.5% (23.8%). Officers recorded a driver leaving the scene less often than elsewhere, 5.3% against 8.6%, while impairment was flagged in 2.4% of crashes but 32 of the serious or fatal ones. Crashes peak in the 3 p.m. hour, only 5.1% happen on Sundays (7.7% across the seven counties), and over the complete years 2018 through 2024 October had the most (1,190) and July the fewest (751).

I-15 and the Southern Parkway

I-15 and the city's interchange ramps add 1,133 crashes inside city limits, 8.1% of the total. I-15 itself recorded 1,064, with 19 serious or fatal and 2 deaths; rear-end collisions made up 28.0% and officers flagged speed in 8.6%. The Southern Parkway (SR-7), a limited-access road, had 39 crashes, 3 of them serious or fatal; they are included in the 12,494 but left out of the street ranking. Crashes below Utah's property-damage reporting threshold never reach these records, and nothing after August 4, 2025 is included.

Your Claim After a St. George Crash

Utah's no-fault rules send the first medical bills to the personal injury protection on your own policy, which must cover at least $3,000 no matter who caused the crash (Utah Code § 31A-22-307). To pursue the other driver for pain and other general damages, the injury has to cross the line drawn in § 31A-22-309, which includes a broken bone, permanent disfigurement or impairment, and medical expenses above $3,000. Fault is compared, and you recover only when the other parties' combined fault exceeds your own (§ 78B-5-818). Most injury lawsuits have a four-year deadline (§ 78B-2-307). Bluff Street, Sunset Boulevard and St. George Boulevard are state routes, and any claim that a road's design or upkeep contributed, whether aimed at the city or the state, begins with a written notice of claim filed within one year (§ 63G-7-402). Read more on our St. George car accident and St. George personal injury pages, and see St. George’s most dangerous intersections for the signals where people on foot and on bikes are struck. The statewide guides explain how fault is proven, how to file a PIP claim and the deadline to bring a case.

Losses You Can Claim

• Medical bills and lost income: emergency care, imaging, surgery, therapy, the wages you missed, and any lasting drop in what you can earn, plus the damage to your vehicle.
• Pain and a disrupted life: the physical pain itself, and the work, recreation and routines an injury takes away.
• What the injury will cost later: treatment your doctors expect you to need in the years ahead, and help at home when an injury does not fully heal.

How These Figures Were Built

Crash records: UDOT's public Crash_Locations series for Washington County, all crash types, January 1, 2018 through August 4, 2025, the last date in the public data. City limits: UGRC's municipal boundary map, applied to every year. Streets: each crash was matched to the closest segment of UGRC's Utah Roads map within 35 meters, preferring the road named in the officer's report; across the full dataset the match agreed with the report about nine times in ten. Serious or fatal: coded fatal or suspected serious injury. Month comparisons use only the full years 2018 through 2024. Driver flags show what the officer recorded, not who was at fault. Comparison figures cover the seven counties in this data. Every city we have ranked this way is listed on our statewide page, Utah’s most dangerous roads.
