About Breath & Blood Tests

When a driver is pulled over or stopped at a sobriety checkpoint, he or she may be asked to submit to a breath test, or a preliminary alcohol screening device at the scene. It is important to understand the difference between a PAS device and a breathalyzer, for one has grave consequences if you refuse to take it. The PAS is conducted at the scene of the police stop; it is a test that can be conducted on the road and is a portable device. The breathalyzer test is conducted once a person has been arrested and is taken back to the police station. Refusal of breathalyzer can result in serious penalties, including the suspension of your driver's license.

A blood test, or chemical test as it is often called, is another type of test to determine a driver's blood alcohol concentration. This test must be administered by a person certified to give the test and must follow strict protocol during chain of custody and testing. When a person gets their driver's license, they imply consent to a chemical test if lawfully arrested for DUI; therefore a person must submit to a chemical test after being arrested for DUI.
