What is true about cargo tanks?

  • They can be loaded or unloaded while attached to the vehicle or removed from the vehicle
  • They remain on the vehicle while they are loaded and unloaded
  • They are loaded and unloaded after being removed from the vehicle
This is a question from page 72 - click here to look up the answer

Quote From Page 100 Of The Illinois CDL Manual:

The glossary at the end of this section gives the meaning of the word "bulk." Cargo tanks are bulk packagings permanently attached to a vehicle. Cargo tanks remain on the vehicle when you load and unload them. Portable tanks are bulk containers not permanently attached to a vehicle. The product is loaded or unloaded while the portable tanks are off the vehicle. Portable tanks are then put on a vehicle for transportation. There are many types of cargo tanks in use. The most common cargo tanks are MC406 for liquids and MC331 for gases.

On hazardous materials shipping papers, all identification numbers must be proceeded by the letters NA or:
  • HM
  • DH
  • UN
  • HZ
This is a question from page 66 - click here to look up the answer

Quote From Page 92 Of The Illinois CDL Manual:

The basic shipping description of a hazardous material on a shipping paper must include the (1) identification number (preceded by the letters UN or NA); (2) DOT proper shipping name; (3) hazardous class or division number of a product (must include subsidiary hazard class when required); and (4) packing group for a product in a roman numeric pattern (may precede with the letters PG).

TruckingTruth's Advice:

It is very rare for shippers to use anything other than the letters "UN" for hazardous materials identification numbers.

Where should emergency response information be kept?
  • In the trailer with the product
  • In a locked fireproof safety box
  • In the same location as the shipping paper
  • In the front glove box

Quote From Page 102 Of The Illinois CDL Manual:

Emergency response information must be kept in the same location as the shipping paper.

TruckingTruth's Advice:

Law enforcement officers will randomly check placarded vehicles to be sure they are carrying emergency response information and that it is kept with the shipping paper, so be diligent about this.

Before calling for help, what are the three basic steps drivers should take if they discover a hazardous material leaking from their vehicle?
  • Drive to the nearest truck stop, pull into a service bay, find the source of the leak
  • Park over a drain, stop the leak, clean the spill
  • Drive to a remote location, contain the spill, locate the leak
  • Park it, secure the area, and stay there
This is a question from page 75 - click here to look up the answer

Quote From Page 103 Of The Illinois CDL Manual:

Never continue driving with hazardous material leaking from your vehicle to find a phone booth, truck stop, help or other reason. Remember that the carrier pays for the cleanup of contaminated parking lots, roadways and drainage ditches. The costs are enormous, so do not leave a lengthy trail of contamination. If hazardous materials are spilling from your vehicle:

  • Park it.
  • Secure the area.
  • Stay there.

What are Placards?
  • Signs put on the outside of a vehicle that identify the hazard class of the cargo
  • Stickers placed on shipping papers that identify the hazard class of the cargo
  • Small stickers placed on the drivers and passengers side window showing the driver has a hazardous materials endorsement
  • Seals placed on rear doors of box trailers or output devices on tankers to prevent hazardous materials from leaking
This is a question from page 64 - click here to look up the answer

Quote From Page 89 Of The Illinois CDL Manual:

Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle that identify the hazard class of the cargo. A placarded vehicle must have at least four identical placards. They are put on the front, rear and both sides of the vehicle. Placards must be readable from all four directions. They are 10 3/4-inches square, square-on-point, in a diamond shape. Cargo tanks and other bulk packaging display the ID number of their contents on placards, or orange panels or white square-on-point displays that are the same size as placards, and placed near the placards.

TruckingTruth's Advice:

Always be sure to ask for an extra placard or two when leaving a shipper in case a placard is blown off the truck during transit.

Before driving vehicles carrying hazardous materials that require placards, you must:
  • Any of these are ways to carry hazardous materials that require placards
  • Hold a CDL with a Hazardous Materials Endorsement
  • Acquire a temporary HAZMAT permit
  • Receive a written Permission Of Endorsement Exemption (POEE) from the shipper
This is a question from page 62 - click here to look up the answer

Quote From Page 86 Of The Illinois CDL Manual:

You must have a CDL with a Hazardous Materials Endorsement before driving vehicles carrying hazardous materials that require placards. You must pass a security background check and a written exam about the regulations and requirements to get this endorsement

TruckingTruth's Advice:

Under no circumstance should you transport a Hazardous Materials placarded vehicle unless you hold a valid CDL with a HAZMAT endorsement.

When checking tire pressure on a hazardous materials vehicle, you must:
  • Use a tire pressure gauge on the trailer tires
  • Use a tire pressure gauge on the steer tires
  • Use a tire pressure gauge on the drive tires
  • Use a tire pressure gauge on all tires
This is a question from page 74 - click here to look up the answer

Quote From Page 102 Of The Illinois CDL Manual:

Make sure your tires are properly inflated. Check placarded vehicles with dual tires at the start of each trip and when ever you park. You must examine each tire at the beginning of each trip and each time the vehicle is parked. The only acceptable way to check tire pressure is to use a tire pressure gauge.

Do not drive with a tire that is leaking or flat except to the nearest safe place to repair it. Remove any overheated tire. Place it a safe distance from your vehicle. Do not drive until you correct the cause of the overheating. Remember to follow the rules about parking and attending placarded vehicles. They apply even when checking, repairing or replacing tires.

TruckingTruth's Advice:

On placarded vehicles, you may not use a tire thumper to determine safe air pressure. A gauge must be used.
