1 . When driving a tank vehicle, valves or manhole covers:
You should never drive a tank vehicle with open valves or manhole covers.
2 . You may leave a vehicle that is carrying explosives unattended:
When transporting hazardous materials, you may leave your vehicle unattended in a safe haven. A safe haven is a location that has been approved for parking unattended vehicles that are loaded with explosives.
3 . Before driving a tank, you should:
Open the drain valves.
When inspecting a tank vehicle, it is most important to check for leaks. Check all pipes, connections, and hoses, especially around joints. Make sure manhole covers have gaskets and that they close correctly.
4 . If you notice hazardous materials leaking while you are driving, you should:
Drive around looking for a person to repair the leak.
If a cargo leak develops while you are carrying hazardous materials, do not continue driving any farther than safety requires. The farther you drive, the larger the contaminated area will become. You should park the vehicle, secure the area, and stay with the vehicle while sending someone else to get help.
5 . The only way to properly check tire pressure is by:
Measuring the height of the tire.
You should examine your tires at the beginning of every trip and after every stop to ensure that they are properly inflated. The only acceptable way to check tire pressure is to use a tire pressure gauge.
6 . When driving at night, you should do all of the following, except:
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.
7 . When coupling a trailer:
When coupling, make sure you couple matching glad hands. They are often color-coded to help drivers avoid mistakes. Typically, blue is used for service lines and red is used for emergency lines.
