What should be done to properly handle a downhill slope in a large vehicle?

To properly handle a downhill slope in a large vehicle, using engine braking and the appropriate gear is crucial. This approach allows the driver to control their speed effectively without over-relying on the brake system, which can lead to brake overheating and reduced effectiveness.

Engine braking involves downshifting the transmission to utilize the engine’s resistance to slow the vehicle down, which is especially important in large vehicles that carry significant weight. By doing this, you harness the natural deceleration caused by the engine, which helps maintain a safe speed while descending.

In contrast, increasing speed to maintain momentum can be dangerous, as it leads to decreased control and increases the risk of losing traction. Coasting down without using brakes is also risky because it can lead to an uncontrolled descent, especially if the incline is steep. Lastly, applying brakes frequently can cause excessive heat buildup, potentially leading to brake failure.

Utilizing engine braking in conjunction with the correct gear for the slope ensures safe and effective control when navigating downhill, making it the proper method for handling such situations.
