Yes, you can stop taking part in breath, blood, and urine testing procedures after you have started. That simple answer requires a good deal of explanation, however, particularly because failing to do everything a police officer asks you to do can have serious legal consequences.
Implied Consent and Fifth Amendment Rights
When it comes to testing suspected drunk and drugged drivers, Ohio police act on the principle of implied consent. This means that simply getting into the driver’s seat can subject a person to all kinds of field sobriety tests and laboratory analyses of your breath, blood, and urine samples unless the person clearly states that he or she does not consent to those procedures.
