Driving under the influence
George Smith, a London taxi cab driver, became the first person convicted of driving a motor vehicle while intoxicated on the 10th of September 1897. He faced charges under the drunk in charge provision of the 1872 Licensing Act. The court fined him 25 shillings for his offense that day. This event marked the earliest recorded instance of such a conviction in history. Legal definitions have evolved significantly since that single moment over a century ago.
Most US states define the crime broadly to include operating or being physically in control of a vehicle while under the influence. An individual found in the driver's seat holding keys while parked may still face DUI charges even if not moving. California requires actual movement of the vehicle to constitute the offense known as driving. State v. Graves (1977) clarified that operate includes acts engaging machinery that sets motive power in motion. The distinction between these terms determines whether a parked car counts as a crime scene.
A small increase in blood alcohol content raises the relative risk of a motor vehicle crash immediately. Alcohol is involved in 30% of all traffic fatalities within the United States. A 2011 study in the B.C. Medical Journal stated clear evidence exists that cannabis impairs psychomotor skills required for safe driving. Drivers using marijuana tend to drive more slowly and cautiously than those who consumed alcohol. Evidence shows they are also more likely to cause accidents than drug-free drivers despite their slower pace.
The Drug Evaluation and Classification program began in Los Angeles, California during the 1970s to detect impaired drivers. This twelve-step process allows government-certified Drug Recognition Experts to determine which categories of drugs affect a suspect. Breath tests and interviews with arresting officers form the initial steps of this evaluation. Toxicological examinations follow later to gather admissible evidence for trial. Police use Standard Field Sobriety Tests to identify impairment at roadside locations.
Car insurance may be automatically declared invalid for an intoxicated driver following any crash involving them. The drunk driver becomes fully responsible for all resulting damages without coverage. Citations for driving under the influence cause major increases in car insurance premiums across the American system. The German model revokes licenses until fitness to drive has been established again through medical-psychological assessment. Commercial Driver's License holders face one-year suspensions or lifetime revocations depending on arrest history.
Sobriety checkpoints serve as roadblocks where police cars check drivers for signs of intoxication in many countries. Non-profit advocacy organizations like Mothers Against Drunk Driving run their own publicity campaigns against impaired driving. All alcoholic products in Taiwan must attach a Prohibiting Drinking and Driving sign on product labels according to local law. The European Union proposed a two-years probationary period without alcohol during 2025 negotiations for new driving license rules. Bar owners may face civil liability for injuries caused by drivers they served while already impaired.
