Which of the following is the correct speed limit for traversing the driving ramp?

The correct speed limit for traversing the driving ramp is 20 mph. This speed limit is established for safety reasons, ensuring that vehicles can navigate the ramp effectively while minimizing the risk of accidents. Driving at this speed allows for a balance between efficient transit and controlled maneuverability, especially in an area that may have pedestrians or other vehicles. The speed is designed to accommodate the necessary response time for drivers to react to any obstacles or changes in the driving conditions, making it a crucial guideline for maintaining safety within the driving ramp areas at O'Hare.
