Good Luck!

What accurately defines the term "tire load"?
  • Total weight of a single vehicle plus its load
  • Weight transmitted to the ground by one axle or one set of axles
  • Light loads are often described as tire loads
  • Maximum safe weight a tire can carry at a specified pressure

Quote From Page 52 Of The Illinois CDL Manual:

You are responsible for not being overloaded. Following are definitions of weights:

  • Gross vehicle weight (GVW): Total weight of a single vehicle plus its load.
  • Gross combination weight (GCW): Total weight of a powered unit plus trailer(s) plus the cargo.
  • Gross combination weight rating (GCWR): Maximum GCW specified by the manufacturer for a specific combination of vehicles plus its load.
  • Axle weight: Weight transmitted to the ground by one axle or one set of axles.
  • Tire load: Maximum safe weight a tire can carry at a specified pressure. This rating is stated on the side of each tire.
  • Suspension systems: Suspension systems have a manufacturer's weight capacity rating.
  • Coupling device capacity: Coupling devices are rated for the maximum weight they can pull and/or carry.

Whether or not you load and secure cargo yourself, you are responsible for all except the following:

Which of the following is true about cargo tiedowns?
  • The combined strength of all cargo tiedowns must be strong enough to lift three times the weight of the piece of cargo tied down
  • On flat bed trailers or trailers without sides, no matter how small the cargo is, it should have at least two tiedowns holding it
  • Cargo should have at least one tiedown for each 25 feet of cargo
  • On flat bed trailers or trailers without sides, cargo that weighs more than 10,000 pounds does not require a tie down
This is a question from page 35 - click here to look up the answer

Quote From Page 53 Of The Illinois CDL Manual:

Cargo Tiedown - On flat bed trailers or trailers without sides, cargo must be secured to keep it from shifting and falling off. In closed vans, tiedowns can also be important to prevent cargo shifting that may affect the handling of the vehicle. Tiedowns must be of the proper type and proper strength. The combined strength of all cargo tiedowns must be strong enough to lift one and one-half times the weight of the piece of cargo tied down. Proper tiedown equipment must be used, including ropes, straps, chains, and tensioning devices (winches, ratchets, clinching components). Tiedowns must be attached to the vehicle correctly (hook, bolt, rails, rings).

Cargo should have at least one tiedown for each 10 feet of cargo. Make sure you have enough tiedowns to meet this need. No matter how small the cargo is, it should have at least two tiedowns holding it.


There are special requirements for securing various heavy pieces of metal. Find out what they are if you are to carry such loads.

What does it mean to block cargo?
  • Securing the front, back, or sides of a piece of cargo to keep it from sliding
  • Only loading one layer of product to avoid a rollover
  • Placing cargo in the center of the trailer for proper load balance
  • Putting a divider between the trailer doors and the product to keep anyone from seeing what product is being hauled
This is a question from page 35 - click here to look up the answer

Quote From Page 53 Of The Illinois CDL Manual:

Blocking is used in the front, back and/or sides of a piece of cargo to keep it from sliding. Blocking is shaped to fit snugly against cargo. It is secured to the cargo deck to prevent cargo movement.

Bracing also is used to prevent movement of cargo. Bracing goes from the upper part of the cargo to the floor and/or walls of the cargo compartment.

How often should you check your cargo to be sure it's properly secured?
  • Every 3 hours or 150 miles
  • Every 2 hours or 100 miles
  • Every 4 hours or 200 miles
  • Every 5 hours or 250 miles
This is a question from page 34 - click here to look up the answer

Quote From Page 52 Of The Illinois CDL Manual:

Check the cargo and securing devices as often as necessary during a trip to keep the load secure. A good habit is to inspect again:

  • After you have driven for 3 hours or 150 miles.
  • After every break you take during driving.

A truck with a higher center of gravity is:
  • More likely to gain traction in a snowstorm
  • Less likely to tip over during a turn
  • More likely to tip over during a turn
  • Less difficult to maneuver when swerving around an obstruction
This is a question from page 34 - click here to look up the answer

Quote From Page 52 Of The Illinois CDL Manual:

Do Not Be Top-Heavy - The height of the vehicle's center of gravity is very important for safe handling. A high center of gravity (cargo piled up high or heavy cargo on top) means you are more likely to tip over. It is most dangerous in curves or if you have to swerve to avoid a hazard. It is very important to distribute the cargo so it is as low as possible. Put the heaviest parts of the cargo under the lightest parts.
