Young people should be conscious of the risks of driving when they have previously drunk alcohol. There are several cases of people who have had accidents on the road because of this reason.One person is killed every half-hour due to drunk driving, statistics also show that alcohol is a factor in almost half of all traffic fatalities. Many young people enjoy night clubbing and drinking with their friends, but the trouble comes when they have to take the car to get  home. When they're on the road after drinking it is very difficult for them to concentrate and they have less ability to react quickly, so they can be involved in serious problems, like hitting a person who is crossing the street or get damaged themselves. 
Local authorities ought to help stopping this situation. They could do it by providing busses every hour in the night so that people who go out don't feel obliged to return home in their cars. Anyway, people should be responsible of their own life and realize that if there isn't any way to come back to their house but going by car they shouldn't drink. 
In conclusion, if we all cooperate, I think that we will be able to stop this awful situation and the deaths due to this will be reduced.
