Which of the following documents should you carry when driving?

When driving, it's essential to carry both a valid driver's license and an inspection card because these documents demonstrate that you are legally authorized to operate a vehicle and that your vehicle meets safety and emission standards. The driver's license serves as your identification and verifies that you have passed the necessary tests to drive. The inspection card confirms that your vehicle has been checked for compliance with safety regulations, which is crucial for the safety of both the driver and other road users. Having these documents on hand is often a legal requirement, and driving without them can result in penalties or fines.

The other options mentioned do not provide the complete set of information necessary for lawful driving. For instance, carrying just a driver's license does not account for vehicle compliance checks, while only possessing proof of identity or vehicle registration fails to meet the dual requirements of personal and vehicle documentation.
