If a law enforcement officer swears that a driver has refused a legal chemical test, what must the Division of Motor Vehicles do?

Answer: B — Revoke the driver's license for at least 12 months

When a law enforcement officer certifies that a driver has refused a legal chemical test, the appropriate action for the Division of Motor Vehicles (DMV) is to revoke the driver's license for a minimum of 12 months. This measure is in place because refusal to take a chemical test—such as a breathalyzer or blood test—implies that the driver may be attempting to evade detection of driving under the influence (DUI) of alcohol or drugs. The law aims to ensure public safety by enforcing consequences for drivers who refuse these tests, as it increases the challenges in prosecuting cases of impaired driving. The revocation period serves both as a deterrent against refusal and as a means to promote responsible driving behavior among all drivers on the road. This administrative penalty underscores the serious nature of DUI offenses and emphasizes the importance of compliance with legal testing procedures.
