Utah roads carry millions of drivers every day, but certain intersections stand out as persistent hotspots for crashes. According to data from the Utah Highway Safety Office, nearly half of all crashes in the state (around 47%) occur at intersections, often due to high traffic volumes, complex designs, left-turn conflicts, distracted driving, and impatient commuters.
While statewide fatalities dropped to 264 in 2025 (the lowest since 2019), intersection-related injuries remain a major concern. This is especially true in the Salt Lake Valley, where urban growth, rush-hour congestion, and commercial traffic converge.
Recent analyses from the Utah Department of Transportation (UDOT) crash data and local traffic studies consistently highlight the same trouble spots. Here are the 5 most dangerous intersections in Utah. These intersections are ranked by the frequency of mentions across 2025 reports for crash volume and severity. Each of these involves major arterial streets that see some of the highest accident totals in the state.
1. State Street & 4500 South (Murray, UT)
This intersection tops or ranks near the top in nearly every UDOT-derived ranking. State Street (US-89) is one of Utah’s busiest north-south arterials, carrying heavy commuter and commercial traffic through a dense retail and residential area. Multiple access points to shopping centers, frequent pedestrian crossings, and high speeds create chaos.
Common crashes include rear-end collisions from sudden stops, side-impact T-bones from left turns, and pedestrian strikes. Drivers often fail to yield or misjudge gaps in the multi-lane setup. This stretch of state street consistently records the highest number of crashes among state highway intersections.
2. Redwood Road & 5400 South (Taylorsville)
Redwood Road (SR-68) is another high-volume corridor with heavy truck and commuter traffic. At 5400 South, the intersection features complex lane configurations, frequent left turns, and nearby industrial/commercial zones that spike activity during peak hours.
Analyses flag it as Salt Lake County’s #1 or #2 crash location due to its high volumes of traffic and frequent visibility issues. On redwood road rear end and angle crashes dominate, often because of individuals rushing through yellow lights or distracted by nearby businesses. Redwood Road overall ranks among the streets with the most intersection accidents statewide.
3. Bangerter Highway & 5400 South (Taylorsville)
Bangerter Highway (SR-154) was built as a bypass to relieve I-15 congestion, but it is signalized intersections have become notorious. The 5400 South crossing sees stop-and-go traffic, short merge lanes, and high speeds between lights—leading to frequent rear-end pileups and side-impact crashes.
This intersection ranks high in 2025 updates because of suburban growth, heavy east-west commuter flows, and turning conflicts. Bangerter Highway as a whole has some of the most accident-prone signalized crossings in the valley, with ongoing construction sometimes adding temporary hazards.
4. Redwood Road & 4100 South (Taylorsville / West Valley City border)
Just north of the 5400 South hotspot, this Redwood Road intersection shares many of the same issues: high daily traffic volumes, complicated turning patterns, and proximity to residential and commercial areas. It frequently appears in pedestrian and driver danger lists because of inattentive left-turning vehicles and inadequate sightlines.
Crashes here often involve angle collisions and sideswipes. Redwood Road’s repeated appearance in top-10 lists underscores why this north-south street is one of Utah’s most dangerous for intersection accidents overall.
5. 1300 East & 2100 (Sugar House, Salt Lake City)
In the heart of the Sugar House neighborhood, this intersection combines heavy urban traffic with significant pedestrian and cyclist activity from nearby businesses, schools, and parks. Confusing angles, multiple lanes, and constant foot traffic make it a hotspot for fender-benders that can quickly escalate.
Drivers speeding through lights or distracted by surroundings frequently cause side-impact and pedestrian-related crashes. It ranks high for severity in local studies and highlights how even “local” streets in busy neighborhoods can become dangerous.
Which Streets Have the Most Car Accidents in Utah?
While the intersections above dominate the headlines, the underlying streets tell the bigger story:
- State Street (US-89) — Appears in multiple top intersections (Murray, Draper, South Salt Lake). Its length through populated corridors and commercial zones drives the highest intersection crash totals.
- Redwood Road (SR-68) — Features repeatedly (4100 South, 5400 South, 6200 South). Heavy truck traffic, suburban density, and long stretches without breaks make it a crash leader.
- Bangerter Highway (SR-154) — Its signalized intersections (especially around 3500–7800 South) generate frequent rear-end and turning crashes due to design and volume.
- Honorable mentions: 2100 South / 3300 South corridors and 700 East in Salt Lake City for pedestrian-heavy urban crashes.
For overall crashes (not just intersections), Interstate 15 remains Utah’s deadliest and busiest road, with complex interchanges like the Spaghetti Bowl (I-15/I-80/I-215) contributing thousands of incidents annually from congestion and high speeds.

These intersections prove that even familiar roads demand extra caution—slow down, eliminate distractions, and watch for turning vehicles and pedestrians. Many crashes stem from driver error (over 90% at intersections nationwide), but road design, signage, and high volumes play roles too.
