Dugway, UT (March 15, 2025) – A semi-truck crash in Tooele County on the night of March 12 resulted in the death of one person and left another seriously injured.
Authorities responded to the scene just before 10:00 p.m. after receiving reports of an overturned semi on Interstate 80 near milepost 78. The Utah Department of Public Safety reported that a blue semi-truck hauling a box trailer had tipped over in the median while traveling eastbound.

Law enforcement officials closed portions of the highway to investigate and clear the scene. Traffic delays were reported in the area while emergency crews worked. The crash remains under investigation as authorities assess the contributing factors.

Truck Accidents in Utah
Large truck accidents in Utah present significant dangers due to the size and weight of commercial vehicles. According to state data, semi-truck crashes account for a notable percentage of traffic fatalities and serious injuries annually. Factors such as high winds, road conditions, and driver fatigue often contribute to these collisions.

Understanding the risks of truck accidents helps highlight the importance of safety precautions. Here are some common causes of these accidents:
- High Winds and Weather Conditions: Utah is known for unpredictable weather, with strong winds capable of toppling high-profile vehicles like semi-trucks. Drivers must exercise caution when traveling in such conditions.
- Driver Fatigue: Long hours on the road can lead to exhaustion, which impairs reaction time and judgment. Federal regulations limit driving hours, but fatigue-related crashes still occur frequently.
- Improper Cargo Loading: Uneven or unsecured cargo can shift, affecting a truck’s stability and increasing the risk of rollovers. Proper loading procedures are essential for safe transportation.
- Mechanical Failures: Brake failures, tire blowouts, and steering malfunctions can lead to catastrophic accidents. Regular maintenance is crucial to prevent mechanical-related crashes.
