Kansas Towing Laws: Do You Need a CDL to Rent a Heavy-Duty Trailer?

Q: Do I need a CDL to rent a car hauler in Kansas? A: For most renters, no. A commercial driver's license is only required when the Gross Combination Weight Rating (GCWR) of your tow vehicle and trailer together is 26,001 lbs or more. Most everyday pickup trucks and SUVs towing a single car hauler with a typical vehicle loaded on it fall well under that threshold, so a standard driver's license is all you need. That said, weight limits and license classifications can have exceptions and local wrinkles, so if you're anywhere close to the line, it's worth a quick call to the Kansas Department of Revenue's Division of Vehicles to confirm your specific setup before you hit the road. Q: What does GCWR mean? A: GCWR stands for Gross Combination Weight Rating. It's the maximum total weight the manufacturer says your tow vehicle can safely handle, including the tow vehicle itself, the trailer, and everything loaded on both — passengers, cargo, fuel, and the vehicle being hauled. You'll find your tow vehicle's GCWR in the owner's manual or on a sticker inside the driver's door. It's a different number from GVWR (Gross Vehicle Weight Rating), which only covers the tow vehicle by itself — GCWR is the one that matters for figuring out licensing requirements, because it accounts for the whole combination. Q: What is the maximum trailer weight you can tow without a CDL? A: There's no single flat number for "trailer weight" in isolation — what matters is the combined GCWR of everything hooked together. As long as your tow vehicle plus trailer plus cargo stays under 26,001 lbs total, you're generally in standard driver's license territory. Here's a simple worked example using our fleet: an average half-ton to three-quarter-ton pickup truck typically carries a GVWR in the neighborhood of 7,000 lbs. Our 22-ft wood deck car hauler has a GVWR of about 9,900 lbs. Add a mid-size sedan weighing roughly 3,500 lbs loaded on the deck, and you land around 20,400 lbs total — comfortably under the 26,001-lb CDL threshold, with several thousand pounds of buffer. That buffer is exactly why most of our renters — people moving a car, hauling a project vehicle, or picking up something from an auction — never need to think twice about CDL requirements. Where things can get closer to the line is with a heavier dually truck towing a fully loaded hauler carrying a large truck or SUV instead of a sedan, or if you're stacking additional cargo weight on top of the vehicle. In those cases, add up the numbers before you leave: tow vehicle weight, trailer weight, and cargo weight, all together against 26,001 lbs. The other thing worth knowing is that CDL requirements are about weight, not trailer length or axle count — a long trailer that's still light stays under the threshold just fine, while a shorter trailer loaded to the gills with something heavy could, in theory, approach it. When in doubt, weigh your loaded rig at a public scale or ask us for the exact GVWR figures for the trailer you're renting, and confirm the current rules with the Kansas Department of Revenue if your combination is anywhere near 26,000 lbs. For the vast majority of car-hauling trips around Salina and central Kansas, though, a regular license and a bit of common sense are all you'll need.
