Which auxiliary controls are checked in the pre-driver check?

In the pre-driver check for an ambulance, the focus is on ensuring that all essential safety and operational components are functioning correctly before taking the vehicle out. Checking the wipers and headlights is critical because these aids directly relate to the vehicle's visibility and safety on the road, especially in adverse weather conditions or low-light situations. Wipers ensure the windshield is clear, which is vital for the driver's visibility, while headlights illuminate the road, making it easier to see and be seen by others.

While the sound system, air conditioning, GPS, and other electronic gadgets can be beneficial for comfort and navigation, they are not essential for the immediate safety and operational readiness of the vehicle in an emergency response context. Thus, the pre-driver check prioritizes elements that impact driving safety directly, making the inspection of wipers and headlights the correct focus.
