What makes hydroplaning most likely to happen:
Explanation: When rainwater mixes with oil, grease, and other substances on the road surface, it creates a slick film that reduces friction between tires and the road. This can cause tires to lose contact with the road surface, leading to hydroplaning. Therefore, hydroplaning is most common during the initial stages of rainfall when the road surface is particularly slippery.
On a steep descent, applying brakes is:
Explanation: While engine braking can assist in slowing down a vehicle on a steep downgrade, the use of brakes is typically necessary to supplement the braking effect of the engine. Brakes provide additional control and can help maintain a safe speed while descending a steep grade. It's important to use brakes judiciously and in conjunction with engine braking to ensure safe descent without overheating the brakes or losing control of the vehicle.

This can lead to insufficient cooling of the engine, resulting in overheating. Therefore, it's essential to ensure that engine belts are properly tensioned to maintain optimal engine function and prevent overheating.
The majority of large cars need ________ shift gears.
