Club Policy/Procedure

The race format rules below apply to all Omaha ACC Racing Club races unless in an expressly noted special event.


*If required based on low attendance, one person can perform the 3 roles below, but host is encouraged to delegate roles.

Race Format


  1. Race practice to be limited to 5 minutes once it is within 30 minutes from race start time.
  2. Commish to announce what constitutes track calls prior to race start.
  3. Track calls should be kept to a minimum.
  4. Drivers and marshals are expected to keep conversation levels such as to be able to hear Race Director.
  5. Race Director is to remind drivers to hookup controllers properly, and marshals to be ready, prior to starting each segment.
  6. Racers must identify lap counter issues during practice; restarting segment should be last resort if problems not identified in practice.
  7. Two minutes allowed between lane qualifying runs, reset counter/clock.

Miscellaneous In-Race Procedures

  1. Tire cleaning shall only be done during "green flag" conditions, and only with tape supplied by Commish.
  2. After start of race, drivers cannot touch cars unless during green flag period.
  3. Driver Crash penalties to be served when "on purpose" crash happens.
  4. Repairs to cars must also only be done during green flag period. Repairs between race segments must stop when clock stops. Exception is during Marshal Damage; see below under "Marshaling".
  5. Repeated violation of above rule will result in 5 lap penalty to offending driver.
  6. Race Director must determine if segment should be restarted or if other adjustments can be made.


  1. Deslots are part of racing, as is marshaling.
  2. Marshals shall emphasize putting cars back on track without damaging car/affecting braids.
  3. Marshal shall not advance re-slotted car significantly ahead of where it deslotted to "make up time" for slow marshalling; However, marshal is encouraged to re-slot car on closest straight section to where it deslotted, which may result in advancing car a couple of sections.
  4. Marshal priority is to re-slot first car that fell off, waiting for traffic to pass. If cannot determine which car was first off, use judgment.
  5. Marshal or driver abuse is inappropriate and will be based on judgment of Race Director; repeat offenses to be penalized 5 laps after initial warning; Race Director can disqualify driver for subsequent offenses.
  6. Each racer must take their turn marshaling a race.
  7. If racer cannot marshal due to health reason, emergency, or need to repair car, let Race Director know in advance if possible. Vacating marshal must find replacement marshal. If there are enough participants to find a substitute, and the marshal does not request a substitute, the marshal who needs the substitute receives a penalty of 5 laps. If insufficient numbers of participants are available, the vacating marshal does not receive a 5 lap penalty, and Race Director will designate a track call area to cover the vacated area.
  8. If expecting a potential important phone call, you should not be racing or marshalling, but let Race Director know in advance.
  9. While marshalling, you are not to operate a camera, use cell phone, or any other activity that does not allow you to use both hands for marshalling. Doing so will be considered not being fully available to marshal, and racer will receive 5 lap penalty.
  10. Driver or marshal can make the initial marshal damage call. Marshall must confirm that a significant reduction in car's performance was due to damage traceable to marshal's direct contact with driver's car. Disputed call will be settled by race director's judgment. Car cannot be handed to driver until it's confirmed to be marshal damage. Driver will get 1/2 the length of the segment to repair the car. If car is rendered inoperable, and confirmed by marshal or, in case of dispute, race director that it's traceable to a marshal's direct involvement, driver may use a substitute car (their own, or a loaner) that meets class specifications.
