How should a driver manage speed on a long downhill slope while in an automatic transmission vehicle?

Managing speed on a long downhill slope in an automatic transmission vehicle requires a careful balance to maintain control and prevent overheating of the brakes. Using both engine braking and the foot brake is the most effective method for several reasons.

When a driver engages in engine braking, they shift the workload from the brakes to the engine by allowing the vehicle to slow down through gear reduction. This helps to maintain a safer speed without the excessive use of the brakes, which can lead to brake fade if used continuously.

Utilizing the foot brake in conjunction with engine braking allows for further control. The driver can apply the brakes during critical moments when more immediate speed reduction is required, thus providing an additional layer of safety.

While coasting in neutral might seem like a way to reduce speed without using brakes, it actually eliminates the driver’s ability to control speed effectively, making it a dangerous choice. This option also poses issues with steering control and braking response, as the vehicle's engine is no longer engaged with the drive wheels.

Simply using the foot brake alone can lead to rapid brake wear and overheating, particularly on a long descent. Shifting to a lower gear is an option for some drivers; however, in automatic vehicles, this can be achieved through engine braking, allowing for better speed
