How to Use the Free Towing Match Calculator for Safe UK Towing
Getting your towing match right is crucial for safe travels on UK roads. Our free calculator simplifies complex DVSA regulations into three easy steps:
1. Find Your Vehicle's Weight
Check your V5C logbook for the "Maximum authorised mass" (MAM). This is your vehicle's legal weight limit when fully loaded.
2. Know Your Trailer's Weight
Include both the trailer's empty weight (plated weight) and your planned load. Rental trailers should display this information clearly.
3. Select Your Licence Type
Most drivers with licences issued before 1997 can tow up to 8,250kg MAM. Post-1997 B licence holders are limited to 3,500kg total (vehicle + trailer).
Why the 85% Rule Matters: For novice tower or unbraked trailers, keeping trailer weight below 85% of your car's weight significantly improves control. Our calculator automatically applies this safety buffer while checking legal limits.
Real-World Example: A 2,000kg car towing a 1,500kg caravan shows 75% ratio - legally acceptable but consider practicing with lighter loads first.
Remember: This free tool covers standard cases. For specialist trailers (horseboxes, boat trailers), consult a certified towing specialist. Always physically check your rig before travel - no calculator replaces proper safety checks.
