When pulling a trailer down a long steep hill, what is the safest practice?

When pulling a trailer down a long steep hill, the safest practice is to drive in a lower gear and keep in the right lane.

Driving in a lower gear is essential because it helps to maintain control of the vehicle and trailer by using engine braking. This reduces the likelihood of the brakes overheating, which can lead to brake failure. By selecting a lower gear, the engine does more of the work to slow down the vehicle, allowing for a safer descent.

Staying in the right lane is important for safety as well. The right lane is often used for slower-moving vehicles and provides more space for maneuvering. This position allows faster vehicles to pass safely on the left, minimizing the risk of accidents.

By combining both practices, drivers can enhance their control and stability while descending steep hills with a trailer, significantly reducing the risk of losing control or causing an accident.
