(1) Blood alcohol level defining “driving while intoxicated.” (2) On-the-spot driver’s license suspension or revocation if blood alcohol content (BAC) is over the level in column 1 or the driver refuses to take a BAC test. (3) Mandatory penalty for violation of the implied consent law, which means that drivers who refuse to take a breath alcohol test when stopped or arrested for drunk driving will have their license revoked or suspended. (4) Prohibits unsealed alcohol containers in motor vehicle passenger compartments for all occupants. Arresting officer not required to witness consumption. (5) Applies only to the driver. (6) With limitations or conditions. (7) Not a per se law, i.e., having the BAC level in column 1 is not automatic grounds for administrative license revocation but is "permissible inference" of drunk driving. (8) Not specifically for drunk driving; Attorney General has established a no plea bargain policy. (9) Officially 0.10 but BAC as low as 0.05 may be considered driving impaired.
