If you were in an auto accident, and you suspect that the at-fault driver may have been under the influence of drugs or alcohol, then you should record the perceptions that made you think that this was the case and inform law enforcement when they arrive on the scene. If the person was slurring his or her words, driving erratically, smelling of alcohol or simply admitted to being intoxicated, then you need to record and share this evidence.
Drunk driving is considered to be a serious offense. It is careless, reckless, and some would say grossly negligent. Your attorney will be able to help you determine the best course of action after an auto accident involving an intoxicated driver.
