Article C12.5.4
Internal cockpit volumes
Chapter: C12
In Simple Terms
This rule defines a protected space inside the cockpit where drivers sit and control the car. Only the steering wheel, pedals, seat, and safety padding are allowed in this zone—no other car parts can intrude into this area to keep the driver safe and comfortable.
- Protects a specific cockpit volume between two measurement points (XC -850 to -1415) where the driver operates the vehicle
- Only steering wheel, pedal assembly, driver's seat, and required padding are exempt from this restriction
- Any other car components intruding into this space would violate the regulation
- Ensures adequate space for driver safety, visibility, and control of the vehicle
Official FIA Text
