Quote From Page 49 Of The CDL Manual:
Shipping Papers After an accident or a hazardous material spill or leak, you may be injured and unable to communicate the hazards of the materials you are transporting. Firefighters and police can prevent or reduce the amount of damage or injury at the scene if they know what hazardous materials are being carried.
Your life, and the lives of others, may depend on quickly locating the hazardous materials shipping papers. For that reason, you must tab shipping papers related to hazardous materials, or keep them on top of other shipping papers. You also must keep shipping papers:
- In a pouch on the driver's door, or
- In clear view within reach while driving, or
- On the driver's seat when out of the vehicle
TruckingTruth's Advice:
The Department of Transportation is extremely strict about these guidelines. If you plan on carrying any type of hazardous materials, be certain to follow these rules regarding where shipping papers are to be kept.
Even if you aren't planning on acquiring a hazardous materials endorsement or carrying any hazardous material loads, you are still required to have basic knowledge about hazardous material regulations. Questions like this are likely to show up on your written exam.
- 6 inch spacing - slide tandems back 2 holes
4 inch spacing - slide tandems back 4 holes - 6 inch spacing - slide tandems forward 3 holes
4 inch spacing - slide tandems forward 5 holes - 6 inch spacing - slide tandems back 3 holes
4 inch spacing - slide tandems back 5 holes - 6 inch spacing - slide tandems forward 2 holes
4 inch spacing - slide tandems forward 4 holes
Quote From Page 0 Of The CDL Manual:
TruckingTruth's Advice:
With 6 inch spacing you're moving 400 pounds per hole so you need to move 3 holes to shift a minimum of 1,100 pounds (400 x 3 = 1,200).
With 4 inch spacing you're moving 250 pounds per hole so you need to move 5 holes to shift a minimum of 1,100 pounds (250 x 5 = 1,250).

Quote From Page 102 Of The CDL Manual:
Stop before a railroad crossing if your vehicle:
- Is placarded; or

- With the engine running and the parking brake on, step on and off the brake pedal to deplete air in the system until the emergency brakes activate
- Chock the wheels, turn the engine off, release all brakes, then step on and off the brake pedal to deplete air in the system until the emergency brakes activate
- With your foot on the service brake, engage and release the parking brake until air is depleted enough for the emergency brake valve to pop out
- Chock the wheels, turn the engine off, release all brakes, then disconnect a brake line and allow the air to deplete which will show if the spring brakes activate automatically
Quote From Page 66 Of The CDL Manual:
Check that spring brakes come on automatically: Chock the wheels, release the parking brakes when you have enough air pressure to do it and shut the engine off. Step on and off the brake pedal to reduce the air tank pressure. The "parking brake" knob should pop out when the air pressure falls to the manufacturer's specification, usually in a range between 20 and 40 psi. This causes the spring brakes to come on.
