A Quick Definition and Acronym Review
• GVW - Gross Vehicle Weight. Means the weight of the vehicle including cargo and passengers.
• GVWR - Gross Vehicle Weight Rating. Means the value specified by the manufacturer as the loaded weight of a single motor vehicle.
• GCW - Gross Combination Weight. Means the actual weight of the loaded vehicle and loaded trailer.
• GCWR - Gross Combination Weight Rating. The value specified by the manufacturer as the loaded weight of a combination (truck and trailer) motor vehicle. In the absence of a value specified by the manufacturer, GCWR will be determined by adding the GVWR of the truck and the total weight of the trailer and any load thereon.

Ensure Connection Compatibility
Verify Functionality of Lights
Cross Safety Chains
Maintain Slack but Don’t Let Drag on Ground
Combined Chain Strength ≥ GVW of Trailer
Hitch/Ball Mount/Ball Rated for Trailer GVWR
Hitch Ball and Trailer Coupling Device Compatible Size

But Did You Consider the
Following?
Ensure applicable ratings and limits are not exceeded
• It is against ARCADIS policy to exceed the
GVWR, GCWR or GAWR of the truck and/or trailer
• Remember, trailer tongue load affects the truck GVW
Truck GVWR +Trailer GVWR ≤ Truck GCWR
Trailer GVW ≤ Trailer GVWRTruck GVW ≤ Truck GVWR
Front GAW ≤ Front GAWR
Combined GAW – Front GAW + Tongue Load ≤ Rear GAWR
Rear GAW ≤ Rear GAWR

Need to Figure Out Your Axle Weights, Tongue Weight or Gross Combined Weight?
Go to a public scale and weigh your combination vehicle using the following methods:
Scales are usually located at truck stops
Note: The controls might be >6 ft off the ground because of semi trucks. USE TRACK!

What About State Regulations Regarding Trailers?
• You should consult State laws regarding trailers
• DOT Facts-006e has a summary of state trailer requirements
- Located on the DOT Program Page of APEX
• Regardless of Federal or State law:
It is ARCADIS policy that all trailers ≥ 1500 pounds GVWR are required to have brakes.
Why? Because truck manufacturer’s only design their brake systems to function properly at the truck’s GVWR not the GCWR!
