If you are pulled over due to suspicion of drunk driving or pulled over for a traffic stop and then the police officer suspects intoxicated driving, you should remember you have certain rights as a U.S. citizen. Namely,
The driver and any passengers have the right to remain silent (except you must show the police your driver's license, registration, and proof of insurance upon request); and
If you are a passenger, you are free to leave.
If you are arrested or detained, you have additional rights, including Miranda warnings.
You can say you wish to remain silent and ask for a lawyer immediately.
You have the right to make a local phone call.
If you believe your rights were violated in any way, try to write down everything you remember, including the police officer's agency (state police, county police, etc.), badge number, and patrol car number.
