8 FAQ’s On Speed Limit for Car Towing Caravan Answered

Caravan towing completely transforms your vehicle’s handling even if you have one of the best cars for towing caravans. Therefore the speed limit for car towing caravan isn’t just a legal formality; it’s a critical safety measure.

Caravan towing speed limits are strictly enforced all across the UK. Every year, thousands of UK drivers receive fines and penalty points simply because they didn’t understand these special restrictions. 

To help you out, we will answer the 8 most common questions about speed limits for cars towing a caravan. So, without any further ado, let’s get started!

1. What’s the Speed Limit for Car Towing Caravan in the UK?

When towing a caravan on dual carriageways, you’ll need to stick to 60mph. Similarly for motorways (including three-lane sections), you are also restricted to 60 mph.

Single-carriageway roads have a lower limit of 50mph, giving you more time to react to oncoming traffic and bends. In towns and built-up areas, the normal 30mph limit applies, but watch out for 20mph zones near schools or busy pedestrian areas.

When you’re towing a caravan or trailer in the UK, these special speed limits apply to keep everyone safe.  These lower limits are legal requirements that account for your longer stopping distances and reduced manoeuvrability when towing. However, in bad weather or heavy traffic, you should go even slower to maintain full control.

Remember, these limits apply to all trailers and caravans, whether you’re towing a small box trailer or a large touring caravan.

2. Can I Use the Right-Hand Lane on Motorways When Towing?

When you’re towing a caravan or trailer on UK motorways, there’s one golden rule about lanes: never use the far-right one. On motorways with three or more lanes, you must stick to the left and middle lanes only.

This rule exists because towing changes how your vehicle handles. You’ll be slower than most traffic, and keeping left helps maintain smooth traffic flow. It also reduces risks when larger vehicles like lorries need to overtake.

While you might see signs occasionally allowing exceptions (like during roadworks), these are rare. The standard rule is simple – if you’re towing, the right lane is off-limits. This applies whether you’re on a busy motorway or a quiet stretch at night.

3. Are Speed Limiters Mandatory for Towing?

Here’s the simple answer: most cars towing caravans or trailers don’t need speed limiters by law. The rule only applies to larger vehicles over 3.5 tonnes – like big vans or motorhomes. These heavier vehicles must have speed limiters set to 60mph.

However, for regular cars, these speed limiters aren’t required, but using cruise control is smart. It helps you stick to the 60mph towing limit without accidentally speeding. Modern cars often have special towing modes that adjust your speed automatically too.

Remember, just because you can go faster without a limiter doesn’t mean you should. The 60mph limit exists because towing changes how your vehicle handles at higher speeds.

4. What Safety Checks are Vital Before Towing an Unbraked Trailer?

Before hitting the road with an unbraked trailer, there are three crucial checks you must complete.

First, verify the trailer’s weight never exceeds 750 kg and is no more than half your car’s kerb weight. This is vital because unbraked trailers rely entirely on your vehicle’s braking system.

Next, thoroughly inspect the hitch connection. Ensure it’s securely locked in place, then attach the breakaway cable as a backup safety measure. After that, walk around the trailer to check all lights are working properly – including brake lights and indicators.

Finally, examine the tyres and reflectors. The tread depth must be at least 1.6mm, and all reflectors should be clean and visible. Remember, skipping these checks risks fines and dangerous situations on the road.

5. How Should I Load a Caravan for High-Speed Stability?

Loading your caravan correctly is essential for safe, stable driving – especially at higher speeds. You should follow these key rules to prevent dangerous swaying and maintain control.

First, always position the heaviest items low and close to the axle. This keeps the weight centered and lowers the caravan’s center of gravity. Place medium-weight items around these, with the lightest goods up high.

Second, fit a quality stabiliser to your tow hitch. These devices significantly reduce side-to-side movement that can occur at 50-60mph. Make sure it’s properly engaged before setting off.

Third importantly, never exceed 85% of your car’s kerb weight. Check your vehicle documents for exact limits. Overloading risks loss of control and illegal operation.

Finally, secure all items tightly so nothing shifts during travel. An uneven load can quickly become unstable at speed. Therefore, you should take time to balance weight side-to-side as well.

6. What are the Legal Requirements for Towing a Caravan in the UK?

Before hitching up your caravan, there are some important legal rules to remember. First, check your licence. If you passed your test after 1997, you might have weight restrictions on what you can tow. Your car and caravan’s combined weight (called Gross Train Weight) must never exceed your vehicle’s limit. 

Also, you will need the right equipment. A proper tow ball that can handle the weight, plus a breakaway cable for caravans over 750kg. If your caravan’s wider than your car, extended mirrors are a must – without them, you risk fines and points.

However, safety checks are non-negotiable. Your caravan needs working lights, good tyres, and proper brakes (essential for anything over 750kg).

Don’t forget matching number plates front and back. And remember – no passengers are allowed in the caravan while it’s moving, no matter how short the trip.

7. How Does Caravan Weight Affect Speed Limits and Restrictions?

Caravan weight doesn’t directly change the speed limit for a car towing a caravan. For safe towing, your caravan shouldn’t weigh more than 85% of your car’s weight.

However, there are important legal rules too. Any trailer over 750 kg must have its own brakes. Going over your car’s towing limit could mean fines and might even invalidate your insurance agreement if you have an accident. 

Heavy loads also need much longer stopping distances. Before you set off, take time to check your caravan’s weight and how it’s packed. Keep heavier items low and near the axle for better balance. 

8.What if You Get Caught While Exceeding the Caravan Towing Speed Limit?

For minor offences of speeding while towing a caravan, you’re looking at a £100 fine and 3 penalty points. But it climbs quickly if you’re caught going way over the set speed limit. The courts can impose fines up to £2,500, and you might even lose your licence if you were driving dangerously over the limit. 

With the help of things like average speed cameras, it has become considerably easier to catch those overspeeding. You can’t argue ignorance of towing limits. Pay the fine or stick to 60 mph and avoid any legal trouble.
