8 . The leakage rate for a triple combination vehicle with air brakes should be no more than ____ in one minute during a static leakage test.
When performing a static leakage test on a triple combination vehicle with air brakes, the leakage rate should be no more than 5 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.
9 . When making a left turn where there are two available turn lanes, a driver should begin the turn in the rightmost lane because:
If making a left turn where there is more than one available turn lane, you should always choose to begin your turn in the rightmost lane. Large vehicles often have to swing right to make left turns. Because of this, it is safer for you to have other left-turning traffic to your left instead of to your right. This will allow you to have the best possible view of other turning vehicles and will lower the risk of your vehicle colliding with them.
10 . When starting an engine:
After a vehicle is started, the warning lights and buzzers should go out after a few seconds. If the warning signals do not turn off, there may be something wrong with the vehicle.
11 . 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.
12 . Air tank drains:
Compressed air in an air brake system usually has a certain amount of water and oil in it. This can harm the system if allowed to accumulate. Air tanks have drain valves to aid in removing water and oil from the compressed air.
13 . Looking far ahead of your vehicle while driving is:
Good drivers look down the road at least 12 to 15 seconds ahead of their vehicles. This makes it possible to identify hazards early, when drivers are more likely to have time to respond appropriately.
14 . What should you do if your vehicle gets stuck on railroad tracks?
If your CMV gets stuck on railroad tracks, you should immediately leave the vehicle and get away from the tracks. Check the signposts or signal housing at the crossing for emergency contact information and call 911, or another appropriate emergency number.
