To obtain driving privileges at O'Hare, what document is required?

To obtain driving privileges at O'Hare, a valid driver's license is required because it serves as the primary identification and proof of a driver's ability to operate a vehicle legally. A valid driver's license ensures that the individual has passed the necessary tests and met the criteria set by the state to safely drive. This document is essential for regulatory purposes and is necessary for the enforcement of traffic rules within the airport's jurisdiction.

While vehicle registration and proof of insurance are crucial for driving in general, they do not qualify an individual to drive at O'Hare without having a valid driver’s license first. A temporary driving permit may allow limited driving privileges, but it typically does not provide the same level of authority as a valid driver's license. Therefore, having a valid driver's license is the key requirement for gaining the necessary driving privileges at O'Hare.
