Brazil has the most strict zero tolerance Law for drinking and driving, valid all over national territory. It is different from USA where the law varies but all states have some kind of penalties.
In spite of the fact that Lei Seca (Dry Law) to seems so strict , many car accidents have been happening to young people from 18 to 25 years old.
The popular take on drinking and driving is most of think It is a great law even though they do not take it seriously because have been drinking and driving.
For Lei Seca to be effective, the government should invest in scare educational advertising. Perhaps showing the dead victims of accident would raise awareness for no drinking and driving.
