Texas Towing Regulations
Texas Towing Regulations Explained (Plainly)
Texas trailer law is straightforward once you know where to look. Here’s everything a homeowner or weekend renter actually needs to know, with the statute numbers if you want to dig deeper. All references current as of May 2026.
First, two acronyms you'll see everywhere
- GVWR (Gross Vehicle Weight Rating) — the maximum a single vehicle is built to weigh, including itself and its load. Stamped on a metal sticker, usually on the driver-side door jamb or the trailer tongue.
- GCWR (Gross Combination Weight Rating) — the maximum combined weight of your truck plus your trailer plus all the stuff inside both of them.
These are ratings, not actual weights. You can legally tow a trailer whose actual weight is less than the GVWR even if the sticker says a big number.
Driver's license
You do not need a special license to tow most rental trailers in Texas. A regular Texas Class C driver’s license covers you for any combination where:
- Your truck has a GVWR of 26,000 lbs or less, AND
- Your trailer has a GVWR of 10,000 lbs or less.
A Class A non-commercial license is required if you’re towing a combination over 26,001 lbs GCWR and your trailer’s GVWR is more than 10,000 lbs (Texas Transportation Code §521.081). For our fleet, the only trailers that approach this are the 24′ tilt and 30′ deckover when fully loaded behind a heavy-duty truck — and only if your truck’s GVWR is high enough to push the combination above 26,001 lbs. Most pickup-and-trailer combinations stay under that line.
TL;DR: If you have a regular Texas driver’s license and drive a typical half-ton or three-quarter-ton pickup, you’re licensed for everything we rent.
Brakes
Texas requires trailer brakes on any trailer with a gross weight over 4,500 lbs (Texas Transportation Code §547.401(b)). There’s a narrow exception: a trailer between 4,500 and 15,000 lbs gross weight doesn’t need brakes if it’s towed at 30 mph or less — not realistic for highway driving, so plan on needing them.
Every trailer in our fleet over 4,500 lbs has electric brakes. You’ll need a brake controller in your truck. Most modern tow vehicles have one built in; if yours doesn’t, an aftermarket controller installs in an hour. See our Electric Brakes Guide for setup.
Breakaway brakes
Texas Transportation Code §547.405(c) requires that any trailer over 4,500 lbs gross weight with brakes have an automatic breakaway system: if the trailer separates from the towing vehicle, the trailer’s brakes must apply automatically and stay applied for at least 15 minutes. Every applicable trailer in our fleet is equipped with a breakaway switch and a small battery to power it. Your job is to clip the breakaway cable to your hitch receiver before you leave the yard.
Lights
Per Texas Transportation Code §547.322, every trailer must have at least two red taillamps visible from 1,000 feet, mounted 15–72 inches off the ground. The rest of Chapter 547 covers brake lights, turn signals, clearance lights for trailers 80″ or wider, side marker lights, and license plate illumination. All of our trailers come fully outfitted — your responsibility is to confirm everything works before leaving.
Safety chains
Safety chains are required by 37 Texas Administrative Code §21.5. They must be:
- Rated for the gross trailer weight
- Crossed under the trailer tongue
- Attached to approved points on the towing vehicle (not the bumper)
- Approved type per Texas DPS standards
Crossing them creates a cradle that catches the tongue if the coupler ever fails — that’s the whole point. Two chains, crossed, every time.
Registration
All non-farm trailers operating on Texas roads must be registered with the Texas DMV. We handle this for our fleet — the trailers you rent from us are registered and plated. You don’t need to do anything.
State safety inspection
As of January 1, 2025, Texas no longer requires annual safety inspections for non-commercial vehicles (HB 3297, 88th Legislature). Trailers are not part of the eliminated program either way. There’s a $7.50 Inspection Program Replacement Fee on annual registration. Emissions tests still apply in certain counties (Travis County is one of them) for the towing vehicle.
Dimensions
Per Texas law, your towing combination cannot exceed:
- 65 feet total length (truck + trailer + bumpers)
- 14 feet height
- 102 inches width (excluding mirrors and safety devices)
Our largest trailer — the 30′ deckover — paired with most pickups stays well within these limits.
What if you get pulled over?
A traffic stop while towing isn’t different from any other stop. Pull over to the right shoulder as far as you can. Stay in your vehicle. Hand the officer your license, registration, and insurance — for our rental, the rental agreement also lives in the glove box and shows the trailer is legally in your possession.
