Managing steering while going down a steep hill is crucial for maintaining control over the vehicle. Using a lower gear when descending allows the engine's braking effect to assist in controlling speed. This technique enhances stability, as it helps to avoid the vehicle gaining excessive speed, which can lead to loss of control. A lower gear increases engine RPM, allowing for better responsiveness when steering.

When in a lower gear, the vehicle also maintains better traction on the roadway, which is especially important on steep grades where conditions can be unpredictable. This method reduces reliance on the brakes, thereby preventing overheating and brake failure that can occur from constant brake application.

While other methods may seem attractive, such as using a higher gear or following the vehicle in front closely, they do not offer the same level of control or safety. Steep descents require careful management of speed and vehicle dynamics, and selecting the appropriate gear is a fundamental part of that equation.
