All vehicles must be equipped with a five-point automotive seat belt system.
All five belts must be securely attached to the vehicle frame or structural members using mechanical fasteners such as nuts, washers, and bolts. Questionably small fasteners, zip ties, and tape are unacceptable. The harness must be capable of lifting the entire vehicle from the ground with the driver and batteries in place.
Each waist belt must be mounted to a structural point at least 3 inches below the top of the driver’s waist.
The shoulder harness must be mounted behind the driver and form an angle of 80 to 120 degrees relative to the seat back, measured at the driver’s shoulder. The shoulder harness must be attached to a structural point at least 3 inches below the driver’s shoulder and must be installed without interference from the seat or other items. The seat itself, or anything added only to the seat, shall not be considered a suitable guide. Guides must be part of the roll cage or vehicle structure.
The seat belt, shoulder harness, and crotch strap must secure the driver in a position that prevents excessive movement. The shoulder harness must be installed so that it cannot slip off the driver’s shoulders while driving. In the event of a sudden stop, the restraint system must prevent the driver from sliding forward and maintain the driver’s shoulders in the driving position. The seat belt system must securely restrain the driver in the event of a vehicle rollover.
