What is “preventive maintenance” of a vehicle?

- Maintenance of unexpected vehicle failures.
Why this is the answer
The correct answer in the official bank: Regular and planned maintenance to ensure the proper function of the vehicle and its systems.
Preventive maintenance aims to stop faults before they happen. It is done regularly and according to a plan, such as the manufacturer's service schedule, so the vehicle and its systems, like brakes, tyres and lights, keep working properly. Occasional, unplanned maintenance left only to the driver's judgement, or fixing failures after they occur, is repair rather than prevention.
