What gear should you use when driving down a steep hill?

Using a lower gear when driving down a steep hill is essential for maintaining control and safety. When in a lower gear, the engine can help slow the car down through engine braking rather than relying solely on the brakes. This reduces the likelihood of brake overheating, which can lead to brake failure on long descents. Lower gears provide more torque and better traction, allowing for a safer descent as the vehicle can respond more effectively to any changes in the terrain or the need for braking.

Driving in neutral or high gear can be dangerous. If the vehicle is in neutral, you lose the ability to effectively utilize engine braking, making it difficult to control speed. Driving in high gear or overdrive also reduces engine braking effectiveness and can lead to an increased reliance on brakes, increasing the risk of brake failure. Thus, selecting a lower gear is the safest approach when descending steep hills.
