Section Chest Protection

All drivers in all Kid Kart, Junior 1, Rookie, and Cadet classes in all Divisions, are required to present for pre-race tech inspection, a chest protection device with a Specification 20.1/1 SFI Certification (ages up through 8) or Specification 20.1/2 SFI Certification (ages 9-12). These ages are guidelines for proper sizing.

This device must be worn whenever such drivers are on track in their kart. The Grid personnel are empowered to prevent a driver from entering the track without this device, just as they would a driver without a neck collar or gloves.
