Drunk driving is a criminal offense or traffic violation in which a person drives a vehicle under the influence of alcohol or other intoxicating substances. The exact blood alcohol content limit varies by country, but in most countries, it is illegal to drive a vehicle with a Blood alcohol level of 0,5 per mille or higher.
Drunk driving poses a significant danger to road traffic and can lead to serious accidents with injuries or even fatalities. The consequences of drunk driving can vary greatly depending on the country and circumstances, and range from a fine to imprisonment or the revocation of a driver's license. In some countries, people convicted of drunk driving (in Germany, usually from 1,6 per mille, see Alcohol MPU) were convicted, including a Medical-psychological examination (MPU) before they can obtain a driving license again.
