Smoke from a nearby grassfire is being blamed for dimishing visibility, leading to the crash.
Authorities say four motorists have been hurt in an 18-vehicle pileup during smoky conditions from grass fires in the Texas Panhandle.
Department of Public Safety Trooper Gabriel Medrano said Friday that the crashes near Amarillo happened during low visibility from several grass fires.
Medrano says a vehicle apparently blew a tire, sparking the fires Thursday afternoon along Highway 60.
Medrano says the wind sent the smoke across the highway, causing multiple crashes in the eastbound lanes.
He says nobody suffered life-threatening injuries in the accidents.
Traffic had to be diverted for several hours.
