The cause of a devastating 2017 collision near Concan, Texas between a pick-up truck and a bus came down to items found in the truck’s cab after the crash: marijuana cigarettes and prescription drugs.
The National Transportation Safety Board (NTSB) has determined that the March 29 accident was caused by the 20-year-old pickup truck driver’s failure to control his vehicle due to his use of marijuana in combination with his misuse of clonazepam, a sedative used to treat seizure and panic disorders.
