If you decide to drink, the last thing you should ever do is drive. It's not safe to get behind the wheel when you're intoxicated. If you do, you could end up causing problems that lead to legal trouble.
DUIs are usually avoidable, but yet people are stopped and arrested every day. The truth is that the authorities are waiting to see people make mistakes on the roads. When they do, they can check their blood alcohol concentration. Even if your BAC is below .08%, you could still end up facing charges.
