How to Use the UK Safe Towing Calculator: Your Essential Guide
Towing safely in the UK isn't just good practice - it's the law. Our calculator helps you avoid fines and stay safe on the road. Here's how to use it effectively:
Step 1: Know Your Vehicle's Weight
Find your vehicle's kerb weight in the owner's manual or V5C logbook. This empty weight is crucial for the 85% guideline - the golden rule for caravan towers.
Step 2: Weigh Your Load
Visit a weighbridge to get accurate measurements of your loaded trailer. Remember:
- Trailer shops often provide free weighing
- Include all luggage and water tanks
- Distribute weight evenly
Step 3: Check Your License
Those who passed their test after January 1997 can only tow:
- Trailers up to 3,500kg MAM
- Combined weight under 8,250kg
Understanding the Results
Our calculator checks three key UK requirements:
- 85% Rule: Caravans shouldn't exceed 85% of your car's weight
- Nose Weight: Keep between 25kg-100kg for stability
- Legal Limits: Matches your setup to DVSA regulations
