What Is The Law When Towing a Trailer?

In the USA, the laws and regulations around towing are complicated and vary depending on which state you're in. There are several rules that you can follow, however, that are standard in every state. So, if you are towing a trailer behind your vehicle, make sure the following is in place:

  • License Plate Light: The vehicle or trailer you're towing is fitted with an illuminated license plate. Driving without a license plate on the trailer could result in you receiving some hefty federal fines.
  • Operable Back Lights: When towing a trailer, you should make sure that all the lights, including indicators and brake lights, are functioning properly.
  • Safety Chain: There must be a safety chain connecting the vehicle or trailer in tow to the vehicle towing's tow hitch, just in case the hitch connection fails.
  • Reflectors: Small or big, it's important to have reflector lights on the trailer you're towing so that other road users can easily spot you and the trailer in low-visibility conditions.
  • Clearance Lights: Clearance lights are also a must-have as they improve the visibility of the trailer to other road users and give an idea of how wide the trailer is.

Some of the trailer laws that differ by state require that you have even more safety equipment and adhere to other limitations such as:

  • License & Limits: Some states require that you have a certain endorsement on your driving license in order to drive a vehicle that's towing, and some have the requirement that you're over a certain age.
  • Breakaway Brakes: Another precautionary measure, breakaway brakes apply stopping force to the actual trailer in the event that the hitch fails and it disconnects from the vehicle doing that doing. Check if this is a requirement in the state you intend to operate in.
  • Tie Downs: Some states require that you tie any cargo that isn't fully contained in the trailer down with cargo straps or tie-downs.
  • Flares: In the event of an accident, some states will require that you release a flare if you're able to in order to clear off the section of the road.
  • Dimension Limits: There a various trailer length limits and width limits you'll have to research and adhere to when driving cross country with a trailer. What is expected in one state may not be the same once you've crossed the border, so plan accordingly.

Basic Driver’s Guide To Towing a Trailer

Now that you know some of the regulations for towing, here is an easy guide for learning to drive with a trailer in tow for the first time:

  • Vehicle Type: Know what type of vehicle is best for towing - the smaller the car, the less likely it is to be rated for towing. High torque output, a rear-wheel drivetrain, and a long-wheelbase setup all make for the highest possible towing capacities in a vehicle. A high axle ratio also improves towing capability. There are many vehicles to consider when looking for the best SUV for towing a trailer, from the GMC Yukon to the Ford Expedition Max.
  • Hitches: There are three types of hitches - conventional hitches, of which there are five different classes, gooseneck hitches, and fifth wheel hitches. The type of hitch on the vehicle will also determine the size of the hitch ball and ball mount.
    • Class 1 Conventional Hitch: Up to 2,000 lbs.
    • Class 2 Conventional Hitch: Up to 3,500 lbs.
    • Class 3 Conventional Hitch: Up to 8,000 lbs.
    • Class 4 Conventional Hitch: Up to 10,000 lbs.
    • Class 5 Conventional Hitch: Up to 16,000/17,000 lbs in regular trucks and SUVs, and 18,000/20,000 lbs in commercial applications.
    • Gooseneck Hitch: Around 30,000 pounds - ideal for livestock trailers, horse boxes, flatbed equipment haulers.
    • Fifth Wheel Hitch: Around 30,000 pounds - good for RV trailers and large campers.
  • Vehicles like the Ram 3500 are able to pull up to 37,000 lbs with a fifth wheel at the time of writing, but there are many more on our list of the best trucks for towing with such impressive towing capabilities.
  • You also get different types of hitch receivers, ranging from bumper hitches, front hitches, weight-distribution hitches, and pintle hitches. Always ensure you use the right application for your needs.
  • Hooking Up: If you're going to be towing a vehicle or trailer for the first time, we have a comprehensive guide to towing a trailer with your vehicle here. If you're set up to tow and just need a refresher on how to go about it, you can follow these steps:
    • Line up the trailer's coupler directly with the tow hitch on your vehicle using your rearview camera or the help of another person.
    • By using the jack that's attached to the front end of the trailer's frame, adjust the height of the trailer so that the coupler is just slightly above the vehicle's tow hitch.
    • Secure the trailer's safety chain around the vehicle's tow hitch.
    • There is a release on the trailer coupler that you'll need to raise before you can latch the trailer coupler onto the vehicle's tow hitch. Once properly attached, the coupler's release will click back into the locking position.
    • Lift the tongue to ensure that the coupler is securely attached to the tow hitch.
    • Raise the trailer jack up so that it is off the ground and completely out of the way.
    • Finally, connect the trailer's electrical connector to your vehicle and check that the indicator and brake lights are all working.
    • Secure any guide wheels or other dangling equipment out of the way.
    • Check that all lights are in working order.
  • Loading Tips: Tips for driving with a trailer start with how you load, believe it or not.
    • Equal weight distribution is key to loading the trailer as too much weight at the rear of the trailer could cause it to fishtail, while too much weight up front could cause the vehicle to sag at the rear, resulting in poor handling and reduced braking power. Ideally, spread the load equally over the axles of the trailer.
    • Adjust your vehicle's side-view mirrors to ensure that you can see all the way to the rear ends of either side of the trailer. If need be, consider equipping your vehicle with telescoping tow mirrors.
    • Make use of ratchet straps or tie-downs where need be to secure the cargo in the trailer.
  • Driver-Assist Tech - Many automakers offer advanced driver-assistance technologies that will prove very helpful when you're driving with a trailer. Some vehicles come equipped with these as standard, but you may have to pay extra in some cases. If you tow regularly, it's a worthwhile investment.

    • Blind Spot Monitoring

Do tow speed limit laws apply to freeways?

The general rule of thumb is that towing speed limits are usually around 10 mph lower than the speed limit that applies to motorists who aren't hauling anything. This applies to freeways too. Pay attention to the differences in various states, though, as these may differ across borders and depend on the type of trailer you've hitched.

Can you tow a trailer with a rental car?

This will depend on the vehicle you're renting and the vehicle rental company's policy. Some companies may even specialize in hiring out such vehicles to assist you with towing. In general, however, it is not advised to use a rental car for anything you have not discussed, clarified, and agreed upon with the rental agent themselves.

Can you tow with an electric vehicle?

Towing with an electric vehicle or hybrid vehicle is possible, but due to weight, regenerative braking systems, and decreased range when towing, EVs aren't often given a tow rating in the US. EVs were not designed with this capability in mind, but you can read more about towing with an EV or hybrid here.

Is it hard to drive with a trailer?

Once you're on the open road, driving with a trailer is relatively easy-going if you stick to the speed limits. Maneuvering through tighter roads, parking, and reversing with a trailer can be rather difficult, however. It is a skill you need to practice and should always be taken seriously - driving at high speeds and losing control will be disastrous.
