IRVING, Texas (AP) — Police say three Dallas-area firefighters have been hurt and a trucker killed when his 18-wheeler hit a stopped ladder truck at a DWI wreck scene.

Irving police Officer Steve Burres says the firetruck rolled and came to rest on its side in the crash early Sunday. The tractor-trailer rig ended up on its side and caught fire during the Highway 183 wreck.

Burres says three firefighters, who were thrown from the firetruck, were transported to a hospital with injuries not believed to be life-threatening. One has a concussion.

The trucker died at the scene. His name wasn't immediately released.

Burres says a man suspected of drunken driving was arrested in the original single-vehicle accident. Another driver who hit a stopped patrol car at the site also faces a DWI count.
