>True enough, but I think it's still up to the cop's discretion to let you go on your way if you pass the field test. They're usually not the one to administer the breathalyser anyways, they call in a specialized unit in a mobile van. (at least they do here in Phoenix)

Wow, things have changed.

I once swerved to miss a squirrel in DC. (Oh, the jokes that could be made! <g>) The cop only saw the swerve and pulled me over. There was no specialized unit at all. I had to walk a line and blow into the breathalyzer on the spot.

The look of utter disappointment on the eager cop's face when the reading was negative was worth the experience. It was all I could do not to bust out laughing. He looked like he'd just learned the truth about the Easter Bunny. LOL

Perhaps that kind of experience is why they now have specialized units.
