What other tests can be required of suspected drunk drivers?
If a police officer has reasonable suspicion that a driver has been drinking, he or she can ask the driver to take a breath or chemical test. The breath test can be administered in the field or back at the police station. A device that is blown into will show the Blood Alcohol Content level (BAC) of the driver. A chemical test uses samples of the driver’s blood or urine to determine the BAC.
