In the context of motor vehicle collisions, a driver under the influence of a drug—even a prescription drug—is treated the same as a driver operating a motor vehicle while under the influence of alcohol. Drugs can significantly alter a driver’s perception and may impair judgment and the speed at which he or she reacts to changing circumstances on the road. Moreover, some drugs can have hallucinogenic effects or blur the driver’s vision while behind the wheel.
If, after speaking with the other driver, you feel that something is just “not right,” share your observations with the police officer who comes to the accident scene. It may very well be that the at-fault driver was under the influence of drugs at the time the accident occurred.
