What is a potential consequence of driving without a valid license?

Driving without a valid license carries significant legal repercussions, which is why the answer highlighting fines, vehicle impoundment, and possible arrest is appropriate. When a driver is caught operating a vehicle without a valid driver's license, law enforcement officers may impose fines as a penalty for this violation. Additionally, the vehicle can be impounded by authorities, leading to further costs and inconvenience for the driver in retrieving their vehicle.

In numerous jurisdictions, including Guam, driving without a license can also lead to arrest, particularly if the individual has previous offenses or if it is categorized as a more serious infraction. This reflects the legal system's approach to promoting public safety and compliance with driving regulations.

The other potential consequences—such as receiving a verbal warning or mandatory enrollment in a defensive driving course—do exist in some contexts but do not generally apply to the more serious nature of driving without a valid license, making them less likely to be the outcome in such a situation. Vehicle auction is not a standard consequence for this infraction, and generally occurs for different reasons. Therefore, the consequences associated with driving without a valid license are appropriately represented by the chosen answer.
