If one drinks and drives, then almost every time something bad will happen or on the side slight chance one get home safely then good job. You don't need to read this then or do you cause highly unlikely that you can get home safe twice. But anyway three things that could happen to you are one hurt you self, two hurt some one else, and three is that you get caught and arrested.
One when you can hurt your yourself because when you drink it slows your judgement down and you cant think straight and then you get in the car and hit a street light. Also drinking impairs your judgement so you probably wont even have your seat belt on. So you go through the front windshield.
Two is instead of hitting a street light you hit a person walking or playing on the sidewalk or even hit another car. Then you will feel guilty for the rest of your life let alone have to pay for the medical or car damages to your car and there car. Hopefully they don't die also.
Three will happen with all the others if you hit something the cops will be called and they will test you for drinking with a drug test. Or if you don't hit anybody don't think that your safe and wont get arrested thought cause drinking impairs your judgement and you don't intend you may speed or swerve. And a paroling cop will pull you over to arrest you.
That is why you should not drink and drive. If you can resit you shouldn't drink at all but if you have to have a designated driver to take you home or if you are at a friends spend the night or call a taxi
