An early-morning crash on state Route 18 south of Enterprise was reported by a school bus driver heading south when they noticed a set of headlights leave the roadway in their rear-view mirror Wednesday. Shortly after 6:30 a.m., a school bus driver was heading south on SR-18 near mile marker 35 when she noticed a vehicle’s headlights in her rear-view mirror that appeared to leave the roadway and either roll or spin around before crashing. The bus driver, unable to stop at the time, called emergency dispatch to report the incident. Utah Highway Patrol Trooper Austin Ipson told St. George News they arrived to find a dark green minivan several yards from the highway where it came to rest on the shoulder. The driver reported no serious injuries. The driver told authorities he was heading south on the highway toward St. George when he fell asleep and the minivan began veering to the right.
