Abstract
In today's society, leisure activities and parties occupy an important place in our lives. On weekends, people want to go out, to enjoy themselves and to party. However, for some people, party means drinking alcohol. More and more young people consume alcohol without moderation with the aim of getting drunk and enjoying to the maximum. However, when the party is over, it is necessary to come back home and a lot of people drive their cars even if they consumed too much alcohol. An alarming report ensues from this tendency: 15-24 people are victims of road accidents in France. They represent 26 % of the persons killed on the road in 2005 for only 13 % of the population.
