WISCONSIN CDL TANKER PRACTICE TEST

11. A material’s hazard class reflects:
the methods for handling spills or leaks in the absence of fires.
the emergency response information related to the material.
the risks associated with the material.
the type of packaging required to transport the material.
12. Tank vehicles:
are easier to control than most other vehicles.
require less space for stopping and turning than most other vehicles.
have a high center of gravity.
have a low center of gravity.
13. Tire load is defined as:
the minimum tire pressure.
the weight transmitted to the ground by 1 tire.
the minimum safe weight a tire can carry at a specified pressure.
the maximum safe weight a tire can carry at a specified pressure.
14. Unbaffled liquid tankers have nothing inside to slow down the flow of the liquid. Therefore:
side-to-side surge is very strong.
top-to-bottom surge is very strong.
forward-and-back surge is very strong.
All of the above.
15. Your vehicle has air brakes. To stop, you should:
pull the parking brake control knob out.
release the accelerator, push in the clutch, and shift to Neutral at the same time.
pump the brake pedal 3 times.
push the brake pedal down.
16. Hydroplaning:
only occurs at extremely high speeds.
only happens when tire pressure is higher than normal.
never occurs at speeds below 40 mph.
can occur at speeds as low as 30 mph.
17. Excessive use of the service brakes results in overheating. Too much heat can:
cause the brakes to grab.
cause the brakes to squeak.
cause the brakes apply unevenly.
make the brakes stop working.
18. Letting air out of hot tires:
will cool the tires down.
will have no effect on the tires.
should not be done, because the pressure will be too low when the tires cool off.
will help relieve the extra pressure.
19. Before loading or unloading any flammable liquids, you should:
turn off the engine.
turn on the headlights.
start the engine.
light up a cigarette.
20. Air tank drains:
are used to move air to the brakes.
should not be used in wet weather.
protect the tanks and the rest of the system from too much pressure.
are used to remove water and oil from the air tanks.
