They already do it here in Idaho - it’s supposedly authorized by the individual when they sign for the license.
To what extremes will they go if I don’t cooperate?
implied consent
How long before “implied consent” means they can search your house without a warrant?
Or pull some blood and hair samples to do a tox screen at random?
Getting a driver’s license doesn’t mean signing away your constitutional rights.
Sure. When you sign your license you waive your rights. If when you sign your license you also write ‘under duress’ you can spend a couple million fighting the administrative law courts and the ABA and still lose. The best thing to do if you are caught...Plead Broke.
Here in Texas, too, it’s been the case for decades. I don’t see much difference between a mandatory blood test or breathalyzer, frankly. It’s at the officer’s discretion.
