UK Towing Laws Explained - What Can You Legally Tow?
UK towing law is one of the most misunderstood areas of motoring. This guide cuts through the myths and explains exactly what you can legally tow, using clear language and real-world examples.
Quick Answer
- ✔ Most drivers with a full UK licence can tow up to 3,500kg
- ✔ You do not need B+E
- ✔ Trailer plated weight does not not prevent you from towing it
- ✔ Actual towing weight must stay within the vehicle’s limits
Do I Need a Special Licence to Tow?
Passed before 1 Jan 1997
You can usually tow a vehicle and trailer combination up to 8,250kg MAM.
This is normally shown as Category BE on your licence.
Passed on or after 1 Jan 1997
You can tow trailers up to 3,500kg MAM on a standard Category B licence.
The towing vehicle must be capable of doing so.
The Biggest Source of Confusion: Trailer Plate vs Actual Weight
🔍 Key Terms Explained
- Trailer Gross Weight (MAM / GVW): Maximum the trailer can weigh when fully loaded
- Actual Trailer Weight: What it actually weighs on the day, including the load
- Vehicle Towing Capacity: Maximum weight the vehicle is allowed to tow
⚖️ The Legal Reality
You are not towing illegally simply because a trailer is plated higher than your vehicle’s towing capacity.
What matters is the actual weight of the trailer and load - this must not exceed the vehicle’s towing limit.
Visual Summary: UK Towing Laws
A clear visual guide summarising licence rules, trailer weight flow, and the down-plating myth.

Understanding Trailer Weight Limits
The trailer plate shows the maximum potential weight, but the actual loaded weight must be within your vehicle’s towing capacity.
Real-World Example
Vehicle towing capacity: 1,800kg
Trailer plated gross weight: 3,500kg
✔ This combination is legal as long as the actual trailer weight (including load) does not exceed 1,800kg.
The plate shows maximum potential - not a legal requirement to load it fully.
🚫 The Down-Plating Myth
Many people believe that if a trailer's plated weight (MAM/GVW) is higher than their vehicle’s towing capacity, they must “down-plate” the trailer to a lower weight. This is not true in the UK.
What matters legally is the actual weight of the trailer when loaded. As long as the trailer’s actual loaded weight is within your vehicle’s towing capacity and does not exceed the trailer’s plated maximum, you are perfectly legal.
✅ You do not need to down-plate a trailer to match your vehicle. Down-plating is only used in very specific commercial or continental situations - it is not a requirement for UK towing.
Always ensure your vehicle handbook and trailer documentation are followed for safe and legal towing.
The key takeaway: Trailer plate weight is maximum potential, not a legal barrier. Focus on the actual loaded weight and your vehicle’s towing capacity.
Frequently Asked Questions
Can I tow a 3,500kg trailer with a 1,800kg-rated vehicle?
Yes, provided the trailer’s actual weight does not exceed 1,800kg.
Do I need to down-plate my trailer?
Usually no. Down-plating is not required if the actual towing weight is legal.
What do roadside checks look at?
Enforcement focuses on actual weights, axle limits, and vehicle capability - not unused capacity on the trailer plate.
