In Arizona, what could lead to a vehicle being impounded during a traffic stop?

In Arizona, driving without a valid license is a serious violation that can lead to a vehicle being impounded during a traffic stop. The law requires that all drivers possess a valid driver’s license while operating a vehicle. If a law enforcement officer stops a driver and finds that they lack a valid license, the vehicle may be impounded to prevent further operation of the vehicle by an unlicensed driver. This action is taken to ensure public safety, as unlicensed drivers may not have the necessary knowledge of traffic laws or the skills required to operate a vehicle safely.

The other options, while they may be violations of traffic laws, do not typically result in vehicle impoundment. For instance, a loud exhaust system may incur fines but does not pose the same level of risk to public safety as unlicensed driving. Similarly, using an expired fuel sticker or not wearing a seatbelt may lead to citations but are generally addressed through fines rather than impoundment.
