Last time I played golf I played with a lawyer and talked to him about this. His recommendation is to say that you need to talk to your attorney if he has any questions. This requires the police to shut off there video camera so the police will have basically zero evidence on you. I don't know if this is for all states or just Texas. But if you do this you probably will end of having to go to court and spend a couple grand.

If I was drinking but wasn't drunk I would just lie and say I hadn't had anything to drink and take a chance that they wouldn't give me a sobriety test. If they chose to test me I may or may not take it. Then if I got arrested I would refuse the breathalizer and all further testing from that point.
