What is a key principle of maintaining smooth driving?

Maintaining smooth driving is essential for safety, comfort, and the efficient operation of an ambulance, especially in emergency situations. One of the key principles illustrated by the correct choice is the practice of keeping the vehicle rolling to avoid unnecessary stops. This technique contributes to a more fluid driving experience, as it reduces the need for sudden accelerations or braking, which can be jarring for passengers and can compromise the stability of the vehicle.

When the vehicle is kept rolling, it also enhances the responsiveness of the driver in emergency scenarios, allowing for quicker adjustments to avoid obstacles or changes in traffic conditions. This approach helps in maintaining momentum, which is vital for both the swift arrival at the destination and the safe transport of patients, as sudden stops can worsen their conditions.

Smooth driving is ultimately about balance—balancing speed, control, and safety—thereby ensuring that the ambulance can navigate through traffic efficiently while providing the best care possible to patients on board.
