What is the best technique to use when driving on a steep hill?

Using lower gears when driving on a steep hill is essential for maintaining control of the vehicle and avoiding a loss of speed. This technique allows the engine to provide more power and torque, which is especially helpful when ascending. Lower gears also enhance engine braking when descending, reducing the reliance on the brakes. This can prevent overheating and excessive wear, as well as increase the driver's control over the vehicle's speed.

Employing higher gears on a steep hill can lead to inadequate engine power, resulting in potential stalling or losing control because the engine may struggle to maintain speed. Turning off the engine not only compromises safety by eliminating power steering and brakes but also does not effectively save fuel when driving uphill. Frequent application of the brakes while driving downhill can lead to brake fade, where the brakes become less effective due to overheating, thereby increasing the risk of losing control. Hence, using lower gears is the best practice for both safety and vehicle performance on steep inclines.
