Why can't the driver's license and vehicle license be kept in the car at the same time? It is mainly to prevent thieves from using the vehicle and both documents for illegal activities after the vehicle is stolen. The following is a related introduction to the driver's license and vehicle license: Driver's License: Driving a motor vehicle requires certain driving skills. Without these skills, driving a motor vehicle recklessly may lead to traffic accidents. Generally, people cannot drive on the road without a license. Vehicle License: The motor vehicle license is the legal document that permits the vehicle to drive on roads within China. The vehicle license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page contains the endorsed certificate core, while the back displays the vehicle's photo, sealed in plastic. The supplementary page is the endorsed certificate core.
