Rulebook

Section I — Driver requirements

• All drivers must attend the drivers meeting.
• All drivers must possess a valid driver's license.
• Drivers must wear long pants and closed toe shoes.
• A helmet is required. Must be SA2010 or SA2015; 2020 open faced helmets are allowed. All helmets must have a working chin strap, and it must be used.
• NJMP helmet requirements: Snell SA2015 or Snell 2020, closed face helmets only. No open face helmets and no M (motorcycle) endorsement helmets are allowed at NJMP.
• Road speed is 10 mph in all areas off the track.
• No trucks, vans or SUVs without approval. Any soft-top convertibles must have rollover protection — see below. Stacked reserves the right to refuse track use to any vehicle deemed unsafe for participation.
• Passengers are not permitted.
• Drones are not permitted.

Section II — Vehicle requirements

Vehicle inspection is conducted at the beginning of every event, before the drivers meeting. Any car deemed unsafe will not be able to participate until all safety requirements are met. Brakes, drivetrain, chassis and suspension are all inspected for safety.

• Fire extinguishers are highly recommended for all events. They must be mounted properly — no zip ties — and must be within reach of the driver while they are fastened into their seat. Minimum 2lb rated.
• Everything loose inside your vehicle must be removed, including floor mats, cell phones, baby car seats, sunglasses and tires.
• Absolutely no fluids can be leaking out of your car.
• The battery must be securely tied down with proper hardware. No duct tape, wood blocks, bungee ties, rope or zip ties. If the battery box is in the driver's compartment it must be sealed and non-venting; if it is not sealed, it must vent to the exterior of the car.
• All suspension bushings and ball joints must be in good condition with no play or clunking.
• All cars must have all lug nuts present on both wheels and spacers.
• A heat shield is highly recommended. It must protect the brake and clutch master cylinder, and is only required for cars with exhaust manifolds on the same side as the brake/clutch master cylinders. If your engine bay is unmodified this is not required.
• Coolant overflow is required. It can be a bottle, but the hoses must be properly fastened to the tank.
• Brake lights must be operational.
• Tow hooks are highly recommended front and rear. They must be highly visible and/or their location clearly marked. Soft straps are not required but are recommended for ease of use.

Convertibles

All convertibles must have proper rollover protection. Fiberglass tops do not qualify — they provide no structural support.

To participate in a Stacked On Track event, convertibles must have four point, structural roll hoops installed which meet the requirements of SCCA Solo 1 Time Trials rules. These roll bars can be bolted in or welded, but must provide a full hoop with down bars from the corners of the hoop, triangulating toward the rear of the car.

If you are unsure whether a factory roll bar qualifies, email us at info@stackedontrack.com so we can review it.

Section III — Harnesses and seats

• Harnesses must be mounted properly. In-date harnesses are recommended; expired harnesses must be in good shape with no rips or tears.
• Harnesses must be mounted using proper hardware. When using eye bolts which go through the floor, large fender washers must be used.
• Harness shoulder straps must be mounted to a roll cage or a separate harness bar, and should not be outside of 20° of horizontal. The seat cannot be used as a guide for the harness. Harness mounting points must attach to the chassis or roll cage/harness bar — not to the seat or seat rails.
• If the car does not have a roll cage, a harness bar can be used to mount the shoulder belts when using a 4, 5 or 6 point harness. A 4, 5 or 6 point harness is required for any vehicle equipped with a roll cage; a minimum of 5 point is recommended.
• Refer to manufacturer specs for proper installation and maintenance procedures.
• If stock seats are used, the OEM seat belt must be used. Harnesses are not permitted with seats that do not have provisions for them.
• If race seats are used with a stock seat belt, the lap belt portion must pass through the holes in the sides of the seat.

Driver classes

HPDE is split into four groups. Full descriptions are on the program page.

Intro

New to HPDE. Experienced lead instructors on site teaching line, speed, turn approach, gear selection and braking. Passing is very limited. Mandatory classroom and post-session debriefs.

Novice

Newer to HPDE — two or more track events — and has driven this track before. Passing is very limited. Mandatory classroom and post-session debriefs.

Intermediate

Must keep pace, stay on line, be consistent and show good situational awareness with proactive point-bys. Passing limited to specified zones; point-bys required. Coaching available on request.

Advanced

Experienced HPDE drivers, current and former racers, and instructors. No passing restrictions, but point-bys are still required. This is not a race.

Flags

Yellow waving

Vehicle on line or on track. Slow with caution.

Yellow solid

Debris, slow moving vehicle, or a vehicle well off line. Slow with caution. No passing under yellow.

Black, flashed then pointed

The driver being flagged must come into the pits.

Black solid, all stations

Everyone must pit.

Red

All vehicles must come to a stop on track — cautiously.

Blue / yellow

Pass flag. Used to stop slower traffic holding up faster cars. Shown to the slower lead car to alert them of traffic behind and let them by. Point-bys are still required.

Checkered

End of session. All cars must slow down to cool and pit.

Passengers

Passengers are not allowed at this time.

Refunds and credits

Any cancellation notification received 14 days or more before the event is eligible for a credit of those fees, transferable to another Stacked On Track event. If a cancellation or a no-show occurs within 14 days of the event, no credit will be provided or offered.
