What document must a driver carry at all times while operating a vehicle?

A driver must always carry a valid driver's license or permit while operating a vehicle. This document serves as proof that the individual has met the legal requirements to drive, including passing the required tests and adhering to age restrictions. Driving without a valid driver's license or permit can result in serious legal repercussions, including fines and potential arrest.

While proof of insurance and vehicle registration are also important documents that should be kept in the vehicle, they are not legally mandated to be carried on the driver at all times. The traffic violation record is not a required document for driving and does not serve as proof of the ability to operate a vehicle legally. Thus, having a valid driver's license or permit is fundamentally crucial for lawful vehicle operation.
