9 . When backing with a trailer:

When backing, you should pull forward to reposition your vehicle whenever needed. Drift should be corrected immediately by turning the steering wheel in the direction of the drift.

10 . What should you do if the braking system cannot build up hydraulic pressure?

During an inspection, ensure that the wheel bearing/seals are not leaking.

12 . What is the Gross Vehicle Weight Rating (GVWR)?

A Gross Vehicle Weight Rating (GVWR) is the value specified by the manufacturer as the loaded weight of a single vehicle.

13 . What is reaction distance?

Your vehicle's stopping distance can be calculated by adding together your perception distance, your reaction distance, and your vehicle's braking distance. Reaction distance is the distance traveled between the moment you mentally perceive a hazard and the moment you physically hit the brakes.

14 . If you are braking on dry pavement while traveling at 55 mph, how much distance will brake lag add to your overall stopping distance?

The total stopping distance for vehicles equipped with air brakes is made up of four factors: perception distance, reaction distance, brake lag distance, and braking distance. When braking at a speed of 55 mph while driving on dry pavement, the brake lag can add around 32 feet to the vehicle's total stopping distance.
