So you’re driving along the highway one evening, minding your own business, and suddenly looming up in front of you is a DUI sobriety checkpoint…

No problem!  You just pull a small printed sign out of your glove compartment and hold it up to the unopened car window for the cop to read.  He reads it through the glass with his flashlight, a quizzical look on his face…and then reluctantly waves you through the checkpoint.

Fantasy?  Watch this YouTube video of a DUI sobriety checkpoint in Florida, in which the driver held such a note up to the window for the cop to read.  The note stated (with Florida state statutes cited):  

I REMAIN SILENT

NO SEARCHES

I WANT MY LAWYER

Please put any tickets under windshield washer.

I am not required to sign – 318.4(2).

I am not required to hand you my license – 322.15.

Thus I am not opening my window.

I will comply with clearly stated lawful orders.

It worked, and the driver got through the checkpoint without opening his window — and possibly having the cop claim that his speech was slurred or that he had alcohol on his breath.  But a word of warning: it may not work for you in your state.  Your laws may be different….and cops generally don’t take well to having their authority challenged.
