Which entities have the authority to sanction a driver for drinking and driving?

The correct answer highlights the role of both the court system and the MVA in sanctioning a driver for drinking and driving. The court system has the authority to impose legal penalties, which may include fines, license suspension, mandatory alcohol education programs, or even jail time, depending on the severity of the offense and the driver's prior record.

On the other hand, the MVA (Motor Vehicle Administration) is responsible for regulating drivers' licenses and has the power to enforce administrative penalties, such as suspending or revoking a driver's license. This dual authority ensures that both legal and administrative measures are in place to address offenses related to drinking and driving effectively.

Other entities mentioned, like insurance companies, while involved in assessing risks and potentially adjusting premiums after a DUI conviction, do not have the same legal authority to sanction drivers directly. Similarly, although police play a crucial role in enforcing laws and making arrests, they do not impose sanctions; that responsibility lies with the court system. Local government might have some jurisdiction over local laws or regulations, but the primary sanctions for drinking and driving come from the court system and the MVA.
