Answer:
The correct answer is: drive in a lower gear.
Step-by-step explanation:
The correct answer is: drive in a lower gear.
When pulling a trailer down a long steep hill, it is important to use engine braking to control your speed and prevent the brakes from overheating or failing. To do this, you should shift into a lower gear (usually 2nd or 3rd gear) and let the engine slow you down, rather than relying on the brakes alone. This will also help you maintain better control of the vehicle and reduce the risk of a runaway trailer.
Keeping in the right lane is generally a good practice when driving a large vehicle or pulling a trailer, as it allows faster-moving traffic to pass you on the left. However, it is not directly related to the question of how to safely descend a steep hill while towing a trailer.
Therefore, the correct answer is: drive in a lower gear.
