Overview

In addition to driving under the influence of alcohol and driving under the influence of other drugs, a third "DUI" offense consists of driving under the combined influence of alcohol and other drugs. The drugs causing or contributing to the impairment need not be illegal, but can consist of lawfully prescribed or over-the-counter medication. Anti-drunk-driving advertising campaigns have aimed to raise awareness of the legal situation and the dangers of driving while intoxicated. Drunk-driving is responsible for a large number of deaths, injuries, damage and accidents every year. In most international jurisdictions, anyone who is convicted of injuring or killing someone while under the influence of alcohol or drugs can be heavily fined, as in France,[1] in addition to being given a lengthy prison sentence.
