Two drivers fled the scene of a collision involving a semitruck that closed westbound U.S. 36 for several hours on Saturday [1].
The incident disrupted major traffic arteries in the Denver and Westminster areas of Colorado, requiring a multi-agency response to clear hazardous materials from the roadway.
The crash occurred Saturday morning, July 11, 2026 [2]. According to the Colorado State Patrol, the collision caused a semitruck to leak between 50 and 60 gallons of diesel fuel [3]. The spill necessitated the immediate closure of all westbound lanes of the highway to ensure public safety and allow for cleanup operations [4].
Fire officials said the closure occurred in Westminster due to the fuel spill [5]. The closure lasted for several hours while crews worked to neutralize the hazard and clear the wreckage [6].
“Two drivers fled the scene of a crash that caused a semitruck to leak 50 to 60 gallons of diesel fuel,” the Colorado State Patrol said [3].
Authorities have not yet identified the drivers who left the scene. The Colorado State Patrol said all westbound lanes of U.S. 36 in Denver were closed Saturday morning after the collision caused the spill [4].
Investigation into the cause of the crash continues as officials seek information regarding the vehicles and individuals involved in the hit-and-run. The impact of the spill and subsequent closure created significant delays for commuters traveling through the region on the weekend morning.

This incident highlights the significant logistical impact that hit-and-run accidents involving commercial vehicles can have on regional infrastructure. Because semitrucks carry large volumes of fuel, a relatively small leak of 50 to 60 gallons is sufficient to trigger full highway closures and hazardous material protocols, turning a traffic accident into a major public safety operation.
