Do not ever take a test. Do not ever offer self incriminate yourself.
I believe in some states that’s an automatic license forfeiture.
This!
Officer: "Have you been drinking?"
Driver: Remain silent.
Officer: "Are you going to answer my question?"
Driver: Remain silent.
Officer: "Are you willing to take field sobriety tests?"
Driver: "No, sir."
Officer: "Please step out of the car."
Driver: "Am I under arrest?"
Officer: Yes or no, if he insists that you step out of the car do so, but don't take the field sobriety tests and don't utter another word. In most states, one is probably better off taking the breathalyzer at the station than declining.
Trust me on this.
