What equipment is required in all vehicles in North Carolina?

Answer: B — valid license plate, working headlights, and a working horn

In North Carolina, every vehicle must be equipped with a valid license plate, working headlights, and a working horn to ensure safety and compliance with the law. The valid license plate is essential for vehicle identification and legality on the road. Working headlights are crucial for visibility during night driving and adverse weather, allowing drivers to see the road and be seen by others. A working horn serves as an important safety feature, enabling drivers to communicate with one another to avoid accidents. While spare tires, insurance documents, turn signals, and windshield wipers are also important features or requirements for vehicle operation, they do not encompass the full scope of mandatory equipment needed in every vehicle as specified in North Carolina law.
