Driving under the influence
Laws by country

The laws relating to DUI vary significantly between countries, particularly the thresholds at which a person is charged with a crime. In many countries, sobriety checkpoints (roadblocks of police cars where drivers are checked), driver's licence suspensions, fines, and prison sentences for DUI offenders are used as part of an effort to deter impaired driving. In addition, many countries have prevention campaigns that use advertising to make people aware of the danger of driving while impaired and the potential fines and criminal charges, discourage impaired driving, and encourage drivers to take taxis or public transport home after using alcohol or other drugs. In some jurisdictions, a bar or restaurant that serves an impaired driver may face civil liability for injuries caused by that driver. In some countries, non-profit advocacy organizations, a well-known example being Mothers Against Drunk Driving (MADD) run their own publicity campaigns against drunk or impaired driving.
