What is the rule about driving on runways or taxiways?

The correct answer is that no driving is allowed unless specified exceptions are met. This rule is in place to ensure the safety and efficiency of airport operations. Runways and taxiways are critical areas for aircraft movement, and any unauthorized vehicle presence can pose significant safety risks, including potential collisions with aircraft.

Regulations governing these areas are strict, and only designated personnel are allowed access under specific circumstances, such as maintenance or emergency operations. Facilities like O'Hare International Airport implement these measures to maintain clear and secure paths for aircraft, preventing disruptions and enhancing overall safety.
