What is required for a vehicle to legally operate on highways in North Carolina?

For a vehicle to legally operate on highways in North Carolina, it must be registered and have a valid registration plate attached. Vehicle registration is a fundamental requirement that ensures the vehicle is recognized by the state, and the registration plate provides a unique identifier for the vehicle on the road. This process also helps in tracking ownership and vehicle history, which is vital for law enforcement and legal purposes.

Having a current inspection sticker is important but is part of ensuring that the vehicle meets safety and emissions standards, rather than a direct requirement for legal operation. Insurance is also necessary to protect against liabilities arising from accidents, but it is not the primary factor for the vehicle's legality in operation. Carrying a driver’s license is crucial for the operator, but not for the vehicle itself. Therefore, the requirement for registration and a valid registration plate is the most essential for a vehicle to be considered legally operable on highways in North Carolina.
