What is the purpose of requiring registration papers on trucks at all times?

The purpose of requiring registration papers on trucks at all times is to ensure that trucks are properly registered and licensed, and that they are operated in compliance with the law. Registration papers serve as proof of ownership and provide important information about the truck, such as its make, model, year of manufacture, license plate number, and the name and address of the registered owner. By requiring trucks to carry their registration papers at all times, law enforcement officers can easily verify that the truck is properly registered and that the driver is authorized to operate it. This helps to deter and detect theft, fraud, and other illegal activities involving trucks. Additionally, registration papers are required for trucks to pass through toll booths, weigh stations, and other checkpoints where the authorities may need to verify the truck's registration status.
