PHOENIX — Several people were treated for injuries after a crash involving two semi-trucks and four cars on the Loop 202 South Mountain Freeway near Buckeye Road. 

The Arizona Department of Public Safety said a commercial driver braked and steered to the left to avoid crashing into congested traffic in the area but failed to stop in time, crashing into five vehicles. 

Firefighters said they treated eight people, adults and children, at the scene. Of those treated, five of them were taken to a nearby hospital, including one young child. 

None of their injuries are life-threatening. 

DPS said the commercial driver sustained minor injuries. Impairment has been ruled out. 

One of the semi-trucks was leaking diesel fuel from one of its saddle tanks. The leak was secured after about 20 gallons of fuel spilled onto the highway, firefighters said. 

The second semi-truck was transporting oxygen and acetylene tanks. Firefighters said those tanks were damaged but not leaking.

The northbound lanes of the freeway were closed at Buckeye Road for about four hours as crews cleaned up the spilled fuel. 

The freeway reopened around 8:30 p.m.
