Reddit reviews How to Overcome Virginia DUI / DWI

>you can't refuse a sobriety test which may involve you speaking without being arrested.

AFAIK, in most states as long as it's an otherwise uneventful traffic stop (i.e., not a crash) you can refuse a roadside Preliminary Breath Test (little handheld box) and field sobriety tests (ABCs, walk-and-turn, etc.). All those do is give the police evidence and/or probable cause to arrest you. In Virginia, if you refuse a test at the station (breath - Intoxilyzer - big typewriter-looking thing with tube; blood draw, etc.) without a valid reason (i.e., medical) you will be charged with Unreasonable Refusal, one of several drunk driving charges.

Regarding searches and questions, unless your speech will give something away (i.e., your drunken state), these are lines you should use:

-I don't consent to any searches.
-I assert my Fifth Amendment right to remain silent and to not answer that question.

ALWAYS be polite. Police have many ways they can make life very stupid for you if you piss them off. You can fight the charges later.
