Why can't a new driver's license be used for the first three days?

[WestonAnn]

A new driver's license can be used in the first three days. There is no such regulation. After successfully passing the fourth subject test of the motor vehicle driver's license, qualified trainees can obtain the motor vehicle driver's license and drive vehicles immediately. There are no relevant laws stipulating that the driver's license cannot be used within three days after issuance. Legal regulations for novice drivers: The first 12 months after a motor vehicle driver initially obtains a driver's license is the probationary period. During the probationary period, when driving a motor vehicle, a uniform-style probation sign should be affixed or hung at the rear of the vehicle. Precautions during the probationary period: During the probationary period, motor vehicle drivers are not allowed to drive buses, passenger vehicles for operation, or vehicles on duty such as police cars, fire trucks, ambulances, engineering rescue vehicles, or vehicles carrying explosive items, flammable and explosive chemicals, highly toxic or radioactive materials, and other hazardous substances; the driven motor vehicle is not allowed to tow a trailer.
