Police are investing a driver of a pickup truck for a possible DUI after a collision with a sedan on State Route 238 Wednesday afternoon, Maricopa Police Department said.

“We are not sure if it is alcohol or drug-related, but there is a DUI investigation currently underway,” MPD Sgt. Steven Judd said.

Ricardo Alvarado, spokesman for the Maricopa Police Department, said the accident occurred around 1:19 p.m. on SR 238 near White Road, west of Ak-Chin Southern Dunes.

Judd said the passenger sedan was heading east on SR 238 when a westbound pickup truck hauling a small trailer crossed over into the eastbound lane.

The truck struck the rear driver-side of the car, causing it to spin.

“(The sedan) did run off the road and went through the barbed wire fences and down into the ravine,” said Maricopa Fire/Medical Department spokesman Brad Pitassi.

The truck continued down the road about 50 yards, and then the trailer disengaged and rolled, Judd said.

The 71-year-old female driver of the sedan was transported to a local hospital with minor injuries. The driver of the pickup truck refused medical attention, Pitassi said.

The collision caused police to temporarily shut down State Route 238. Crews are working to reopen the roadway.
