Spanish Fork, UT (May 6, 2026) – A serious overnight crash involving multiple semi-trucks and a passenger vehicle forced a full closure of Hwy 6 through Spanish Fork Canyon early Tuesday morning. The collision resulted in extensive damage and left two drivers hospitalized with injuries.
Emergency units responded to the scene after reports that a semi-truck traveling westbound crossed the center line and struck two eastbound semi-trucks. The impact caused significant damage to all three commercial vehicles involved, as well as to a passenger car that was also part of the crash.
Two drivers were transported to a hospital for treatment. Their conditions have not been publicly detailed beyond hospitalization. Information about the occupants of the passenger car and their condition has not been released.
The crash led to a complete shutdown of Hwy 6 in both directions while crews worked to clear debris, remove damaged vehicles, and assess roadway safety. The closure remained in place for several hours due to the severity of the collision and the number of vehicles involved.
Authorities continue to investigate the cause of the crash, and more details will be released as soon as they become available. We are thinking of those injured as they receive medical care.
What Factors Can Contribute to Multi-Vehicle Semi-Truck Crashes on Mountain Highways?
Crashes involving multiple semi-trucks on canyon highways often occur in areas with limited visibility and narrow lanes. These roadways can be especially challenging due to curves, elevation changes, and varying traffic speeds.
When a large truck crosses the centerline, even briefly, it can trigger a chain reaction involving multiple vehicles traveling in the opposite direction. The size and weight of commercial vehicles increase the severity of impacts.
Driver fatigue, weather conditions, and roadway alignment are commonly reviewed in these incidents. Investigations typically focus on vehicle movement patterns and road conditions leading up to the collision to determine how the sequence of events developed.
