Yeah, in most states. But, I don't think MO called for the whole taking the blood without a warrant issue. Sure, the license is revoked, but you didn't agree to have part of your body taken away, nor searched.
If you refuse to take the test, the officer takes away your license.
The DMV then convenes an administrative hearing to determine whether the revocation should be made for the duration specified by law.
Moral of the story is its always better not to be arrested for a DUI in the first place since it can be very costly and emotionally draining.
I’ve never had that experience.
