You see the flashing lights behind you and know that you have to stop. The issue that you have now is that you know you've had a few drinks and you are worried about the Breathalyzer test. You know that you are going to have to decide how to handle the police officer's request that you submit to a test to determine your blood alcohol concentration.
The answer to this isn't one that is easy. You do have the right to refuse to take a test to determine your BAC; however, you can't do that without having to deal with the penalties that come along with it. You will face a suspension of your driver's license if you don't take the test when an officer requests that you do so.
