What is the regulation that establishes driver's license requirements?

The regulation that establishes driver's license requirements is primarily governed by the individual state's motor vehicle codes and regulations, which are based on the federal standards set by the National Highway Traffic Safety Administration (NHTSA). Each state has its own Department of Motor Vehicles (DMV) or equivalent agency that outlines specific criteria for obtaining a driver's license, including age, residency, testing, and documentation requirements. These regulations ensure that drivers meet minimum safety standards before operating a vehicle on public roads.
