Maryland CDL Permit Test - Tank

If you must back up, you should exit the cab and check your path for obstacles before beginning the maneuver. Drive as slowly as you can, checking your mirrors on both sides.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.

To remain aware of hazards behind your vehicle when backing, you should frequently check your mirrors on both sides of the vehicle. Have a helper watch your blind spots whenever possible.

When inspecting your vehicle, you should verify that the safety belt is securely mounted, adjusts, latches properly, and is not ripped or frayed.

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

If a cargo of hazardous materials begins to leak, do not move your vehicle any more than safety requires. If you continue to drive, an even larger area will become contaminated. Instead, you should park your vehicle, secure it, stay with the vehicle, and contact the proper emergency personnel. If you do not have access to a phone, you should send someone else to get help.

When examining the engine compartment during a pre-trip inspection, you should check the engine oil level, the radiator coolant level, and the condition of the hoses.
