Why is it important to be in the proper gear before starting down a hill?

Being in the proper gear before starting down a hill is crucial for utilizing engine braking capabilities effectively. When you select a lower gear while descending, the engine can help control the speed of your vehicle by using compression to slow it down. This reduces reliance on the brakes, which can overheat and lose effectiveness if used excessively on a long descent.

Maintaining engine braking means you have better control over your speed and can handle the descent more safely. This also contributes to overall safety, as it allows for a smoother transition through the hill without the sudden increase in speed that can occur if you were in a higher gear.
