What are the three documents that must be carried while driving?

The requirement to carry a license, vehicle registration, and proof of insurance while driving is essential for legal and safety reasons. The driver's license serves as proof of the individual's qualification to operate a vehicle and confirms their identity. Vehicle registration demonstrates that the vehicle is legally registered with the appropriate authorities, showing ownership and compliance with state laws. Proof of insurance is crucial as it provides evidence that the vehicle is insured, fulfilling legal obligations and ensuring financial protection in case of accidents or damages.

The other options include documents that, while possibly useful in certain situations, do not fulfill the legal requirements for driving. For example, a vehicle manual is not a legal necessity, nor is a credit card or driving school certificate when it comes to everyday driving. Similarly, an inspection report, while it may be important for vehicle safety checks, is not mandatory to carry while driving, nor is a warranty or driving record pertinent to having legal authorization to operate the vehicle on the road. Thus, the most critical documents are those that confirm your ability to drive and the legal status of your vehicle.
