29 . How many daily hours of sleep does an adult need to maintain alertness?
Four to five
Being properly rested is essential to the safe operation of a CMV. To maintain alertness, most people need eight to nine hours of sleep per night.
30 . Which gas would cause concern due to a faulty exhaust system?
A leaking exhaust system can introduce carbon monoxide, which is poisonous, into the cab or sleeper berth.
31 . Which of the following is not a cause of hydraulic brake failure?
Most cases of hydraulic brake failure come from one of two causes. The brakes may fail due to a loss of hydraulic pressure or due to overuse on long hills, causing the brakes to fade.
32 . The radiator cap:
Never remove the radiator cap or any part of the pressurized cooling system until it has cooled. Opening the cap while the system is too hot could release steam and boiling water that could severely burn you. If the radiator cap is cool to the touch, the system is likely cool enough for you to open the cap.
33 . In very hot weather, tires should be checked regularly because:
The lug nuts may loosen.
Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being used in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once the tires cool down.
34 . When you must travel down a grade, when should you switch into a lower gear?
At the bottom of the grade
Before starting down a hill, you should shift into a lower gear. This will help get your vehicle to a speed that you can control without having to use your brakes too much.
35 . A serious traffic violation involves each of the following offenses, except:
Following too closely.
Traffic violations classified as "serious" include excessive speeding, reckless driving, operating a CMV without a valid CDL, following other vehicles too closely, and improper lane usage. Consequences for multiple serious traffic violations can result in license disqualification.
