Like in most other states, certain Hawaii drunk driving penalties to those people who are caught driving a vehicle with a BAC (blood alcohol content) of 0.08 or above. For commercial vehicle drivers, the BAC limit is 0.04; for minors (under 21), it is 0.02. As per the “Implied Consent Law” applicable in Hawaii, you have the right to decline to submit to a chemical test of urine, breath, or blood. You will not be awarded any penalty or fine for this. In most other states, refusal to take these test often result in immediate license suspension for a certain period of time. There are no such provisions in Hawaii.
