If a driver refuses to take a breath test to determine his or her BAC level, he or she will be offered a urine test and/or blood test. Officers may not require a driver to take a blood or urine test without a warrant, except in certain situations where criminal vehicular operation (vehicular homicide, bodily injury) is involved.
Refusing to take an alcohol concentration test comes with various administrative sanctions and criminal penalties. Your driver’s license may be revoked, and your DWI charges may be enhanced. Still, it may be in your best interest to refuse to take a test.
