2022 Tire Rack SCCA Time Trials National Tour at Buttonwillow Raceway Park Powered by Hagerty

The Tire Rack SCCA Time Trials National Tour is an engaging, accessible and inclusive nationwide tour designed to give enthusiasts the chance to push limits on track, to experience cars bound only by budget and imagination and to enjoy off-track social activities featuring food, media, photography and fun. Camping at the track is encouraged, friends and family are welcome and food and drink are available on site.

1. Absolutely NO SMOKING is permitted in the area of the hot pits.

2. Speed limit in the North Paddock hot pit lane is 25 MPH and will be enforced. Speed limit begins at the outer K wall, driver’s left upon entrance to the hot pit, and ends past the outer K wall driver’s left by the Pit Out official.

3. Cars stopping for tire pressure checks or other maintenance work along the hot pit wall to the east of the paddock entrance, must exercise extreme caution when re-entering pit lane traffic to access the track or to enter the paddock. Cars stopping along the hot pit wall west of the paddock entrance may make a lap of the track if their session is still green and re-enter the hot pit area or may be pushed back by crew members to the paddock entrance.

4. Cars may not be driven counter course or in reverse.

5. Cars may stop only in designated Hot Pit area clearly marked between the signs. This area is approximately 120 feet east and 120 feet west of the paddock entrance in the K-wall driver’s right.


1. Paddock speeds of racecars, support vehicles, and other conveyances must be safe and prudent for current conditions.

2. The use of all types of conveyances in the paddock is a privilege and may be withdrawn at the discretion of the Race Director. Riding on the outside of any car is prohibited.

3. Children under 12 years of age are required to be under the direct supervision of an adult at all times.

4. Use of bicycles, roller skates, scooters or other conveyances by children under 12 years of age is specifically prohibited.

5. Fire extinguishers are required for each paddock space. It is strongly recommended that competitors have a crew member holding a fire extinguisher, in addition to the fire safety equipment on board the racecar, while refueling.

6. All electrical cables in the paddock must be firmly secured to the ground. No electrical cables are permitted on the ground between the pit lane exit to the paddock and Impound while cars are on course. Officials may require that cables be removed from traffic areas.

7. Modifications or alterations to electrical services at the track are prohibited.

8. Drivers are requested to minimize urban sprawl and efficiently and considerately use space in the paddock area to allow room for other competitors. Trailers not acting as support vehicles and personal (street legal) cars should be parked away from the paddock area to leave room for competitors and race cars.



2. Be advised that no food may be distributed at PIR without prior arrangement with PIR sanctioned concessions. Food may be brought in for personal use only.


1. Drivers may be held financially responsible for damage to PIR facilities (i.e., guard rail, etc.) due to off-course excursions or other incident.

2. The SCCA is charged for cleanup of the paddock area, drivers and crews are to leave PIR clean. Garbage is to be placed in proper 3. receptacles, and it is imperative that participants leave their paddock areas without clutter (i.e., tires, loose garbage, etc.)

4. Tires are to be removed from PIR by the competitors as there is no provision for their disposal at PIR. No oil barrels are provided at PIR.

5. Hazardous wastes, including oil, solvents, brake clean, brake fluid, antifreeze, etc., must be taken with you when you leave PIR.

Per PIR policy, no race car engines may be turned on before 8:00 AM for starting and 8:30 AM for revving.

1. Oregon State law requires functioning mufflers to be used at PIR.

2. Sound level measurements will be made on all cars as early as possible during the practice sessions.

3. PIR HAS A STRICT SOUND/NOISE POLICY PER CITY OF PORTLAND CODE. Cars exceeding a sound level of 102.99 dbA or cars losing mufflers that result in a noise violation will be shown the Black Flag immediately. Proceed to the Black Flag station near the entrance to the pit lane – this is mandatory. Drivers are given one opportunity to make modifications or repairs to be below the limit. Repairs or alterations made in the pit or paddock areas to lower the sound level must be approved by the Officials before re-entering the track. Sound-control officials must be informed when a car returns to the track so that a new sound level reading may be made quickly. A second violation will mean a car will be removed from the event for the rest of the day.

On a following day, the vehicle in violation must re-tech, show what was done to remedy the violation, pass tech, and be re-checked on course via the sound monitor. If the vehicle fails again, it is disqualified from the entire event.

Failure to follow this procedure or failure to enter the pit area promptly on a Mechanical Black Flag for a sound level violation may result in a disciplinary action (disqualification and/or fine).
