What should you do before starting down a hill with a vehicle?

Being in the right gear before starting down a hill is crucial for maintaining control of the vehicle. When descending a hill, it is important to use lower gears to help manage your speed without relying solely on the brakes. Lower gears provide engine braking, which significantly reduces the risk of brake overheating and failure. This method helps to keep your vehicle under control, allowing for a smoother and safer descent.

Shifting into neutral, reducing speed to a specific limit, or using the emergency brake do not address the fundamental need for proper gear selection when going downhill. Being in the correct gear works in conjunction with controlled speed, providing an effective means to navigate inclines safely.
