Washington County, UT (July 30, 2026) – At least one person was injured on Wednesday, July 29, in a collision between a semi truck and a passenger vehicle on southbound I-15 near mile marker 33, close to Pintura, a small unincorporated community in Washington County. The left lane was closed following the wreck.
Heavy rain was reported in the area at the time. This stretch of I-15 climbs through hilly terrain south of Toquerville, where wet roads can make driving conditions more difficult. Drivers passing through were reminded to move over for emergency vehicles.
No further details about the extent of the injuries were immediately available. We hope for a full recovery for everyone involved.
Why Are Truck-Vehicle Crashes More Dangerous in the Rain?
Crashes between large trucks and passenger vehicles carry a serious risk because of the size and weight difference between the two. A fully loaded semi can weigh 20 times as much as a typical car, so the smaller vehicle absorbs most of the impact force, even at moderate highway speeds.
Wet roads add another layer of difficulty, especially for semi trucks that need more distance to stop safely. Rain can also reduce tire traction and cause hydroplaning, where a vehicle’s tires lose contact with the road surface, and the driver loses steering control for a brief but critical moment.
Rolling hills and grade changes, common on this stretch of I-15, can make it harder to judge the distance and speed of an oncoming or merging vehicle in wet conditions. Slowing down, increasing following distance, and turning on headlights during heavy rain are simple steps that can reduce the risk of a serious accident in weather like this.
