Towing Capacity by Reg Calculator
How to Use the Towing Capacity by Reg Calculator in the UK
If you’re planning to tow a trailer, caravan, or horsebox, it’s vital to know your vehicle’s towing capacity. Using a Towing Capacity by Reg Calculator is the simplest way to find out, and it’s specifically designed for UK vehicles. Here’s how you can use it properly and what to look out for.
What is Towing Capacity?
Towing capacity is the maximum weight your car can safely pull. This includes the braked towing capacity (when the trailer has its own brakes) and the unbraked capacity (when it doesn’t). These figures vary between vehicles, so checking yours by registration is the most accurate method.
How the Calculator Works
The calculator uses your UK vehicle registration (also known as VRM) to pull data like make, model, year, and factory towing limits. Simply enter your reg number (for example, AB12CDE), and it’ll show the braked and unbraked towing capacity for your vehicle.
Step-by-Step: Using the Towing Capacity by Reg Calculator
Enter your UK reg number – Make sure it’s exactly 7 characters with no spaces.
Click the “Check Towing Capacity” button – The tool processes the input.
Get your towing data – It displays your vehicle details and the official towing capacity figures.
It’s quick, free, and gives results in seconds. No need to dig through your vehicle handbook or visit the DVLA.
Why Is This Important?
Towing more than your vehicle’s capacity is not just unsafe – it’s illegal in the UK. If you’re caught, you could face fines, penalty points, or worse, cause an accident. Knowing your towing limit keeps you within the law and ensures safe driving.
Common UK Standards to Know
Braked towing limit: Up to 3,500 kg for some 4x4s.
Unbraked limit: Usually 750 kg max.
GVW (Gross Vehicle Weight): Never exceed the total weight allowed for your car, passengers, and the trailer.
MAM (Maximum Authorised Mass): Check both your vehicle’s and trailer’s MAM to avoid overloading.
Final Tip
If the tool doesn’t show data for your reg, it’s likely the database doesn’t have your exact vehicle specs. In that case, check your vehicle’s V5C logbook or contact the manufacturer.
Use this towing capacity by reg calculator anytime before heading out with a trailer. It gives peace of mind and keeps you road-legal across the UK.
