Drugged Driving Video Series

Driving under the influence of drugs other than alcohol or drugs in combination with alcohol is now nearly as prevalent as driving under the influence of alcohol. The numbers of alcohol related fatalities continue on a slight downward trend while the number involving other drugs has been increasing rapidly.

To assist prosecutors and law enforcement officers the AAA foundation funded a grant that permitted the National Traffic Law Center to create a video series. These videos are intended to help prosecutors who are fairly new to the study of drugged driving to develop a basic understanding of the challenges they will face as they prosecute drivers impaired by drugs other than alcohol.
