43. When traveling down a hill:
Explanation
When a vehicle is traveling on a downward slope, the force of gravity will cause its speed to increase.
44. When loading a trailer, weight should be:
Explanation
Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.
45. Bracing is used to:
Explanation
Blocking and bracing are used to prevent cargo from shifting in transit. Blocking is used in the front, in the back, and on the sides of a piece of cargo to prevent movement. Bracing prevents movement by reaching from the upper portion of a piece of cargo to the floor and sides of the cargo compartment.
46. States verify that a CDL or CLP driver has only one such license by:
Explanation
All U.S. states share information about CDL and CLP licenses in a computerized database. If you apply for a license in one state, a state will check this database to verify that you do not already have one such license in another state.
47. When driving at night, you should do all of the following, except:
Explanation
To ensure that you can see as well as possible, don't wear sunglasses when driving at night. If you wear eyeglasses, make sure they are clean and unscratched. Make sure you are rested and alert before driving at night.
48. Too little weight on a steering axle can result in:
Explanation
The weight of cargo in a vehicle needs to be balanced appropriately so that it does not interfere with the vehicle's safe handling. For example, if cargo is placed too far to the rear of a vehicle, the front axle will be under-weighted and the front wheels may not have enough traction for the driver to steer safely.
49. If an Anti-Lock Braking System (ABS) malfunctions:
Explanation
On a vehicle with ABS, a yellow malfunction lamp on the instrument panel will illuminate to alert you if the braking system is not working.
50. To ensure normal stopping power, drivers of vehicles equipped with a front brake limiting valve should:
Explanation
Some pre-1975 vehicles have a front brake limiting valve, which has "normal" and "slippery" settings. The idea behind these valves was to limit the air pressure available to the front brakes when driving on slippery surfaces, and thereby reduce the danger of a front-wheel skid. Studies have found that this is not actually a concern, so if your vehicle has a front brake limiting valve, leave it in the "normal" position.
