Avoiding a drunk driving charge is the easiest thing in the world. Don't drink and drive. Is it that hard? Get a friend to be the designated driver. Take a cab to where you plan to spend the evening and leave in a cab. Some cities have instituted special fare cabs or even free cab rides to help cut down on the death and suffering that drunken driving causes. If you are stopped by the police, and are found to be intoxicated, they will take you in. If there is some doubt that your were actually impaired or you know that you had only a couple of drinks then there may have been an error made while testing your blood alcohol concentration. They may not have followed proper procedure or the device may not have been calibrated correctly. You may have a different metabolism, or if you are diabetic, you will often give a false positive reading. There are many reasons why they may be in error, and you should not be punished for their mistake.
