The Utah Highway Patrol said a box truck was merging out of lanes that were closed for construction when it hit a Subaru sedan. The car lost control and hit a semi truck that was also traveling in the right-hand lane.
The Subaru hit the semi’s gas tank which burst, spilling between 100 to 150 gallons of fuel onto the road.
Crews with the Utah Department of Transportation and other hazmat groups responded to the spill.
UHP said the driver and passenger of the Subaru were transported to the hospital with minor injuries.
All lanes opened to traffic a little before noon Monday.
