France Towing Weight Calculator

How to Safely Calculate Your Car's Towing Capacity in France

Understanding your vehicle's towing capacity isn't just about safety - it's the law in France. Our calculator helps you avoid fines and stay road-legal. Here's how to use it effectively:

Step 1: Gather Your Numbers

Find your vehicle's gross weight in the registration documents. Estimate passenger weight realistically - an adult averages 75kg. Include luggage and cargo in your trailer weight.

Step 2: Know Your License

French law sets different limits:

• License B: Max 3.5 tonnes total (car + trailer + people)
• B96: Adds 3.5 tonnes total + trailer up to 1.3 tonnes
• BE: Professional towing up to 7 tonnes total

Step 3: Check Two Key Limits

The calculator verifies:

1. Legal weight for your license category
2. Physical towing capacity (trailer ≤ 85% of car weight)

When You Get Warnings

Red messages mean immediate action needed. Either reduce load, get a different trailer, or upgrade your license. Yellow warnings suggest caution even if technically legal.

French-Specific Tips

Remember:

• All trailers over 500kg need separate brakes
• Speed limits drop when towing
• Required equipment includes extended mirrors

Check your calculations twice before long trips. When in doubt, visit a certified weigh station. Safe towing protects everyone on the road - your diligence makes French highways safer for all.
