Hotshot GCWR & non-CDL weight checker: CDL or not, and how much you can haul
Enter your truck and trailer GVWRs, their empty weights and the cargo. The hotshot GCWR and non-CDL weight checker shows whether the combination needs a CDL, whether this load is within the ratings, and how much payload is left.

How the checker works
Two separate questions get mixed up in hotshot: does this rig need a CDL, and is this load legal on it? The first depends only on the ratings. The second depends on what's on the scale.
- CDL class (from ratings): Class A when the GVWRs add up to 26,001 lb or more and the trailer is rated over 10,000 lb; Class B when the truck alone is rated 26,001 lb or more; otherwise no CDL
- Actual weight = truck empty + trailer empty + cargo
- Trailer room = trailer GVWR − (trailer empty + cargo)
- Combination room = GCWR (or the sum of GVWRs) − actual weight
- Payload left = the smaller of the two
EXAMPLE A one-ton truck rated 14,000 lb pulls a gooseneck rated 14,000 lb. Combined rating: 28,000 lb with a trailer over 10,000, so a Class A CDL is needed. Empty, the truck weighs 7,900 lb and the trailer 7,200 lb. With 9,500 lb of cargo, actual weight is 24,600 lb. Trailer room: -2,700 lb. The trailer is over its rating, even though the whole rig is under 26,000 lb on the scale. That load needs to be lighter.
The rule behind the CDL answer is in 49 CFR 383.91 CDL Class AGCWR 26,001 lb or more, towing a unit over 10,000 lb GVWR49 CFR 383.91(a)(1): a combination with GCWR of 26,001 lb or more where the towed vehicle's GVWR is over 10,000 lb.49 CFR 383.91Checked Oct 2026.

CDL, no CDL, or over the rating
No CDL, with payload left: a legal non-CDL setup for this load. Keep the ratings in mind when brokers offer heavier freight.
CDL needed: you can't put a non-CDL driver in this rig, no matter how light the load. To run non-CDL, the trailer or truck ratings must change, which usually means different equipment.
Over a rating: don't book it at that weight. Lighten the load, or pass. Overweight on a trailer rating is a safety and liability problem, not just a ticket.
Fast runs on hotshots can push drivers; see how a governed speed changes the week with the speed limiter impact calculator, and check whether a specific offer pays with the load profitability calculator.
Scale it once, then check every load
Shipper and broker systems sometimes ask for codes like a SCAC; see what a SCAC code is in trucking. The what is PTI in trucking guide covers the pre-trip inspection every hotshot driver does. And our small fleet dispatch desk checks every hotshot load against each unit's ratings before it reaches you. This checker is a planning aid; state rules may add limits.
Scale the rig empty once, with full fuel and the driver, and write the numbers on the door jamb card. Every later load check is then simple arithmetic instead of a guess.
Read the ratings off the truck
- Read GVWR from the truck's door sticker
- Read the trailer GVWR from its VIN plate
- Use scale weights for empty truck and trailer, fuel and driver included
- Check the manufacturer's GCWR in the owner's manual
Hotshot weight and CDL questions
01When does a hotshot need a CDL?
A Class A CDL is needed when the combination's gross combination weight rating is 26,001 lb or more and the trailer's GVWR is over 10,000 lb. A truck rated 26,001 lb or more on its own needs at least a Class B. The checker uses the ratings, not the scale weight.
02Can I run non-CDL hotshot with a heavy trailer?
Only if the combined ratings stay at 26,000 lb or below, or the trailer is rated 10,000 lb or less. Many non-CDL hotshot setups pair a one-ton truck with a trailer rated to keep the total under the line, which limits payload.
03Do DOT rules apply to non-CDL hotshots?
Yes, in interstate commerce at 10,001 lb or more. The safety rules, including medical certification, hours of service and inspections, apply even when no CDL is needed.
04What's the difference between GVWR and GCWR?
GVWR is the maximum a single vehicle may weigh loaded. GCWR is the maximum for the truck and trailer together, set by the truck's maker. If no GCWR is listed, the checker adds the two GVWRs.
05Can I lower my trailer's GVWR to stay non-CDL?
Some manufacturers will re-rate a trailer, but it's done by the maker with new paperwork, not by changing a sticker. A lower rating also means less legal payload, so check whether the freight you want still fits.
