What papers must you have when operating a motor vehicle?

When operating a motor vehicle, it is essential to have your license, registration, and insurance card with you. The driver's license serves as proof that you are authorized to drive and have passed the necessary tests to do so. The registration indicates that the vehicle is legally registered with the state and affirms ownership. The insurance card is essential because it shows that the vehicle is insured, which is a legal requirement in New Jersey and most states; it provides financial protection in case of an accident.

Having all three documents ensures that you are complying with state laws while driving. It also helps avoid legal issues that could arise from lack of proper documentation, such as fines or potential liability in the event of an accident. While other options provided may include some elements related to driving, they do not meet the comprehensive legal requirements needed to operate a vehicle legally and safely on public roads.
