National 420 Campaign -- April 17-20, 2026:
No matter the time or day, driving under the influence of marijuana, or any other drug, is an illegal and life-threatening behavior. Ahead of the marijuana culture’s high holiday, 420, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) urges individuals to plan to drive fully sober or to get a sober ride home. Drivers are responsible for keeping themselves and others on the road safe at all times, and that includes on 420. Huntsville Police remind all drivers: If You Feel Different, You Drive Different. Officers will be stepping up enforcement efforts to deter impaired driving.
