“Postcrash toxicology reports indicated that the car driver was negative for alcohol and positive for cannabis, and the [truck] driver was negative for alcohol and other drugs,” a new report from the National Transportation Safety Board states, according to the television station.The investigation also found that Robertson should not have had so many passengers in the vehicle. She had been issued an intermediate driver’s license less than six months before the accident, and under Oklahoma law, a driver with such a license is allowed to carry only one non-household passenger unless a licensed driver at least 21 years of age is also in the vehicle, the television station reports.Medicinal cannabis is legal in Oklahoma but only for those over 18 years of age who have a license for it.The driver of the truck, 51-year-old Valendon Burton, had no drugs or alcohol in his system and has not been charged in connection with the crash.
