For PDX (Level 1) events, the following guidelines apply for restraint systems. Cars equipped with a roll bar may use stock restraint systems, provided that the roll bar does not interfere with the function of the system in any way, or restraint harness per Section 11 of the TTR (Time Trials Rules) For these cars there is no age limit on harnessed so long as the harnesses are in visibly and physically good condition. Cars that do not incorporate roll bars or cages may use the stock restraint sstem in its entireely or use a restraint system that complies with TTR Section 11.

Cars: Street legal cars; Club Racing cars from Spec MIata, Touring or Improved Touring classes; cars which meet the preparation of SCCA Stock, Street Touring, Street Prepared or Street Modified classes. Cars must have a passenger seat and a minimum of 3 point harness for both the driver and the passenger seats. Convertibles must have factory hard top or factory roll over protection and both driver and instructor must fit below a line drawn from the top of the windshield to the top of the roll over protection.
Section 11 says:

A. A four point restraint system, for use in enclosed automobiles only, may be employed where the driver is seated in an upright position. Only 4 point restraints that incorporate a manufacturer designed method for prevention of submarining may be used. Five, six or seven-point systems are highly recommended in all cars including automobiles where the driver is seated in an upright position.
