## About
Enter the rack's published specifications and your car's limits (tow-ball nose weight, roof load and tow-bar type) plus the bikes you want to carry. The checker confirms the total weight against every limit, flags e-bikes and wheel sizes that do not suit some racks, and reminds you about UK rules on lights and number plates. It cannot confirm that a rack fits your exact car model: always check the rack manufacturer's vehicle list or fitting guide.

## How to use
1. Enter your values in the fields above.
2. The result updates automatically as you type.
3. Copy or note the figures you need.

## FAQ
**Where do I find my car's tow-ball or roof load limit?** In the vehicle handbook, or on the plate in the door shut or engine bay. Roof limits include the roof bars and the rack.

**Does it confirm my car is compatible?** No. It checks the limits you enter. For fit, use the rack manufacturer's compatibility list for your exact make, model and year.

**Is the Car Bike Rack Compatibility Checker free?** Yes, with no sign-up or limits.
