Which of the following is a safe remounting speed for emergency vehicles on the paved surface?

When considering remounting speed for emergency vehicles on paved surfaces, a speed of 20 mph is generally regarded as a safe limit. This speed allows emergency responders to maintain control over the vehicle while ensuring that they can react effectively to any potential obstacles or situations that arise in an emergency context.

Driving at 20 mph strikes a balance between rapid response and safety, providing sufficient time for the driver to make necessary adjustments or decisions. Emergency vehicles often have unique handling characteristics, and driving at this moderate speed helps to prevent loss of control while still allowing for a timely arrival at the scene.

While other speeds may seem reasonable, they can be either too fast, increasing the risk of accidents, or too slow, which may delay emergency response times. Therefore, the choice of 20 mph is informed by a focus on both operational effectiveness and the safety of the vehicle occupants as well as other road users.
