8. Drivers trapped behind a slow-moving vehicle often:

At the end of each day of driving, you may be required to make a written report on the vehicle or vehicles driven. Be sure to make note of any issues that could affect the safety of the vehicle or that could lead to a mechanical breakdown.
10. What do air brakes use to make the brakes work?
Many large CMVs are equipped with air brakes. An air braking system uses compressed air to operate.
11. Dry bulk tanks require special care because:
Driving with a dry bulk tank requires special care, both because dry bulk tanks have high centers of gravity and because their loads often shift in transit. Be especially careful when taking turns and curves while operating such a vehicle.

During the on-road driving skills test, you will be evaluated on your gear usage. Select a gear that does not rev or lug the engine; avoid grinding and clashing gears; and avoid shifting through turns or intersections.
13. How does doubling your speed from 20 mph to 40 mph affect your vehicle's braking distance?
Increasing your vehicle's speed will increase your vehicle's striking power and braking distance. Doubling your vehicle's speed from 20 to 40 mph will multiply its braking distance by four.
14. To ensure normal stopping power, drivers of vehicles equipped with a front brake limiting valve should:
Some older vehicles have front brake limiting valves with "normal" and "slippery" settings. Setting a brake limiting valve to "slippery" reduces the vehicle's stopping power, so a driver should make sure the valve is in its "normal" position. Front wheel braking has proven to be effective in all driving conditions.
