Towing on the Motorway: Speed Limits, Safety Tips, and Legal Guidelines

0If you're planning on towing a trailer or caravan for a weekend trip or a cross-country move, it's important to understand the rules and best practices for towing on the motorway. Whether you're an experienced driver or a first-timer, towing changes how your vehicle handles and responds, especially at high speeds.


This guide will walk you through the essentials: speed limits, safety tips, and legal guidelines to help you stay safe—and legal—while towing. Plus, we’ll answer some common questions to clear up any confusion.


Understanding the Basics: What Does Towing Involve?

Towing means pulling a trailer, caravan, or another vehicle using your car or truck. On the motorway, towing becomes more challenging due to higher speeds, increased traffic, and longer braking distances. Even if your car can tow a trailer, that doesn’t mean you’re automatically ready for the motorway.


Why Is Motorway Towing Different?

When you're car towing a trailer on a motorway, you’re dealing with:

That’s why understanding the rules and following best practices is so important.


Speed Limits for Towing on the Motorway

One of the most common questions drivers have is, “How fast can I go when towing a trailer on the motorway?” Here’s the answer:


National Speed Limits for Towing

In most states, the maximum speed limit for a car towing a trailer on a motorway is 55 mph to 65 mph, depending on your location. For example:

These limits are lower than regular car speed limits because towing increases the risk of jackknifing, trailer sway, and longer braking times.

Always check your local state laws because speed limits vary.


Legal Guidelines You Need to Follow

Before you hook up a trailer and head for the highway, make sure you're complying with all legal requirements. Here are the basics:


1. Vehicle & Trailer Compatibility

Your vehicle must be rated for towing the weight of your trailer. Check your owner’s manual to find:


2. Trailer Lights & Signals

All trailers must have:

These lights should be wired correctly to your vehicle. Double-check they’re working before every trip.


3. Safety Chains Are a Must

Using safety chains is a legal requirement in most states. They act as a backup in case the hitch fails. Cross them under the hitch to prevent the trailer tongue from hitting the road.


4. Braking System

If your trailer weighs more than 3,000 pounds, many states require it to have its own braking system. Surge brakes or electric brakes are commonly used.


5. Mirrors and Visibility

Your rear-view mirrors should give you a clear view of the road behind the trailer. If they don’t, you’ll need to install towing mirrors.


6. Load Distribution

Load your trailer evenly and ensure about 60% of the weight is in the front half. This helps maintain stability and reduce sway.


Safety Tips for Towing on the Motorway

Legal requirements are only part of the equation. Smart driving habits will keep you, your passengers, and other road users safe. Here are some practical tips:


1. Drive Slower Than You Think You Need To

Even if the speed limit is 65 mph, that doesn’t mean you should drive that fast. Stay in the right lane and aim for a safe, comfortable speed. This gives you more time to react and helps prevent trailer sway.


2. Increase Your Following Distance

Leave at least 5–7 seconds of space between you and the vehicle in front. You need more room to stop when towing.


3. Avoid Sudden Movements

Avoid sharp lane changes or sudden braking. Make all movements smooth and deliberate.


4. Watch the Weather

Strong winds and heavy rain can make towing dangerous. If conditions look rough, consider waiting it out or taking an alternate route.


5. Practice Makes Perfect

If you're new to towing, practice driving with the trailer in a parking lot or on quiet roads before hitting the motorway.


When You Shouldn’t Tow on the Motorway

There are situations where towing on the motorway isn’t just risky—it could be illegal or dangerous:

When in doubt, don't tow. A few hours of delay are better than risking an accident.


Common Mistakes to Avoid While Towing

Even experienced drivers can make errors while towing. Here are the big ones to avoid:

1. Overloading Your Trailer

Just because your trailer fits more gear doesn't mean you should fill it. Always stay within the weight limits for both your car and trailer.


2. Not Checking Tire Pressure

Low tire pressure can lead to blowouts, especially on the trailer. Check both vehicle and trailer tires before your journey.


3. Ignoring Wind Resistance

A high-profile trailer catches more wind. This can reduce fuel efficiency and cause sway. Reduce speed to compensate, and drive cautiously in crosswinds.


4. Using Cruise Control

Cruise control may not be safe while towing, especially on hills. You need manual control over acceleration and braking.


5. Forgetting the Height of Your Trailer

Be mindful of bridge clearances and overhead obstacles. Know your total vehicle height before entering tight spaces.


Can You Use the Left Lane While Towing?

In many states, vehicles towing trailers are restricted to the right lane or right two lanes on highways with three or more lanes.

For example:

Violating these rules can lead to hefty fines.


What to Do in an Emergency

If your trailer starts to sway or jackknife:

If you have a flat tire or mechanical issue, pull over as far from traffic as possible, turn on your hazard lights, and set out emergency triangles or flares.


Frequently Asked Questions (FAQs)

1. Is it legal to drive a car towing a trailer on a motorway?

2. Do I need a special license to tow a trailer on the motorway?

In most cases, a regular driver’s license is enough to tow a small trailer. However, if you're towing a large trailer or heavy load, some states may require a special endorsement or commercial license. Check with your local DMV.


3. How can I reduce trailer sway on the motorway?
