What does it mean to have a car without hanging?

Having a car without hanging means placing the license plate inside the car instead of mounting it in the designated position on the vehicle body, which is a serious violation of the law. Relevant information about license plates is as follows: 1. Introduction: License plates, commonly known as vehicle plates, refer to the plates mounted on the front and rear of a vehicle, displaying the vehicle's registration number, registration region, or other relevant information. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their primary purpose is to identify the vehicle's region of registration and to enable tracking of the vehicle's owner and registration details through the license plate.
