Buying a caravan, a horsebox, or a large box trailer often comes with an unwelcome surprise: discovering your car licence might not actually cover towing it. Trailer rules changed significantly in recent years, and a lot of drivers are still working from outdated assumptions about what “category B+E” actually means for them.
This guide explains what towing entitlement you need, how the rules changed for newer drivers, and how to check what you’re currently allowed to tow.

What Is Category BE?
Category BE is the entitlement that allows a standard car licence holder to tow heavier trailers than the base category B allowance permits. Historically, anyone wanting to tow a large caravan, horsebox, or loaded trailer beyond category B’s limits needed to pass a separate car-and-trailer practical test to add BE to their licence.
Who Actually Needs to Take a Trailer Test
Whether you need to sit a separate test depends heavily on when you passed your original car test. Drivers who passed before a certain date often already hold some towing entitlement automatically as an “acquired right,” while others need to actively apply and test for it. This is exactly the kind of detail worth double-checking against your specific licence rather than assuming either way.
Acquired Rights: Why Passing Date Matters So Much
Drivers who passed their car test before 1 January 1997 generally retain broader “acquired rights” to tow heavier trailers without ever needing to sit a separate BE test, a legacy of how the licensing categories were restructured at that time. Anyone who passed after that date falls under the newer, more restrictive rules that applied until the December 2021 change loosened things again for future test-passers. This means three people who each want to tow the same caravan could have three completely different legal answers, purely based on the date each of them passed their test — which is exactly why checking your own entitlement directly matters more than following general advice from friends or family.
The 2021 Rule Change for Newer Drivers
In December 2021, DVSA changed the rules around towing for drivers who passed their car test afterward, removing the separate car-and-trailer test requirement for many typical combinations. This was a significant simplification, but it doesn’t mean unlimited towing entitlement — weight limits still apply, and very heavy combinations can still require additional entitlement. Because the exact weight thresholds are technical and it’s easy to misremember them, always verify your specific combination against current official guidance before towing anything substantial, rather than relying on general assumptions.
Understanding Trailer Weight Limits
Towing rules are based on the Maximum Authorised Mass (MAM) of both your towing vehicle and the trailer combined, not simply the trailer’s weight on its own. A heavier tow car generally gives you more headroom before you hit a combined weight limit, which is why two people towing what looks like the same size caravan can be operating under very different legal limits depending on their vehicle.
If You Do Need the Test: What’s Involved
Where a separate BE test is still required, it involves a practical assessment covering trailer-specific skills: coupling and uncoupling safely, manoeuvring including reversing with a trailer attached, and a road-driving section. It’s a distinct test from your original car test, booked and taken separately, and typically benefits from dedicated practice time with a trailer rather than assuming your existing driving experience automatically transfers.
A Worked Example
Consider two neighbours who both want to tow the same 2,000kg caravan. One passed their test in 1995 and likely already holds acquired towing rights covering the combination without further action. The other passed their test in 2019, before the December 2021 change, and may need to check whether their specific vehicle-and-trailer combination requires a separate BE test. Both are towing an identical caravan, but their legal position is entirely different.
How to Check What You’re Currently Entitled to Tow
The safest way to confirm your current towing entitlement is to check your licence categories using the official “view your driving licence” service online, which reflects your actual entitlement rather than assumptions based on when you think you passed your test. If you’re unsure, it’s worth checking before you commit to buying a trailer or caravan that turns out to be outside what you can legally tow.
Common Mistakes Towing Drivers Make
- Assuming all car licences cover the same towing weight. Entitlement varies significantly by when you passed your test and what’s specifically listed on your licence.
- Confusing trailer weight with combined vehicle-and-trailer weight. MAM limits are based on the total, not the trailer alone.
- Not checking insurance separately. Being legally entitled to tow doesn’t automatically mean your policy covers it — always confirm with your insurer.
- Assuming the 2021 rule change means no limits at all apply. It simplified many cases but didn’t remove weight limits altogether.
- Leaving trailer test practice until the day before the test. Reversing with a trailer attached is a distinct skill that benefits from proper practice time.
Do New Drivers Face Any Extra Towing Restrictions?
Newly qualified drivers should also bear in mind that towing a trailer doesn’t exempt them from the New Drivers Act penalty point rules covered elsewhere on this site — an offence committed while towing is treated the same as any other driving offence for totting-up purposes.
Frequently Asked Questions
Do I need a special licence to tow a caravan in the UK?
It depends on the combined weight of your vehicle and trailer, and when you passed your original car test. Many combinations are covered under standard category B or the post-2021 rules, but heavier setups may still require category BE.
What changed with towing rules in December 2021?
DVSA removed the requirement for a separate car-and-trailer test for many drivers who passed their test afterward, though weight limits still apply to what you can tow.
How do I know if I already have BE entitlement?
Check your current categories using the official online driving licence checking service, which shows your live entitlement rather than relying on assumptions.
Does towing entitlement expire?
No, once a category is added to your licence it doesn’t expire through lack of use, though your licence itself may still need periodic renewal.
Is the trailer test different from my original driving test?
Yes. It’s a separate practical assessment focused specifically on trailer coupling, manoeuvring, and towing skills.
Does my insurance automatically cover towing if I’m legally entitled to?
Not necessarily. Always check with your insurer separately, since legal entitlement to tow and insurance cover for towing are two different things.
Final Summary
Towing rules in the UK depend on a combination of when you passed your test, your vehicle and trailer’s combined weight, and whether you’ve taken a separate trailer test. The 2021 rule change simplified things for many newer drivers, but it’s still worth confirming your exact entitlement before committing to a caravan, horsebox, or heavy trailer.
