Board of Directors: The Board of Directors (herein referred to as BOD) shall be composed of President, Vice-President, Secretary-Treasurer, Promotion & Public Relations Officer, and a representative from each hill climb event not otherwise represented on the BOD. Member organizations will be responsible for notifying the NHA President as to the name of this person.
    2. Conference calls may be arranged at the discretion of the BOD.
    3. The minutes of the NHA Annual General Meeting, and any other declared NHA meeting, will be made available to all members via posting on the NHA website (

    2. Only member organizations can host an NHA sanctioned event.
    3. Member organizations must submit an annual membership fee of twenty-five dollars ($25.00) prior to November 1 of each year. At this time a schedule of hill climb events for the following year must be submitted to the BOD to facilitate planning at the Annual General Meeting.

  3. Event Planning

    1. Organizations hosting an NHA sanctioned and insured hill climb event will guarantee that all current NHA members who have paid their annual dues (members in good standing) will have their entries accepted for the event. Said entries must be submitted in accordance with entry deadlines established for general registration by the host organization.
    2. Member organizations are encouraged to send out brochures, flyers, registration forms, and/or other printed items as early as possible. At the latest, said materials should be received by potential entrants no later than two weeks prior to the registration deadline.
    3. Proposed new hill climb sites shall be inspected by two NHA members, appointed by the BOD, for suitability and safety. At least one of the NHA inspectors should have hill climb racing experience in a higher speed race car (i.e. classes FA, FF, CSR, GT1, SPO, or similar high performance classes). The NHA inspectors will make a written recommendation to the BOD regarding acceptance of the proposed site. The BOD will make the final decision as to an NHA sanction for the event.
    4. Events added to the schedule after April 30 will be non-pointed events for NHA purposes for that year, and will not count for "Climbed Them All" awards.
    5. Should an organization wish to change the dates of an event after March 1, the organization will be responsible for, and guarantee notification of, all prospective entrants by regular mail, including NHA members, provided that the change is accepted by the BOD. The NHA will assist in notification via the website, but this will not take the place of mail notification.
    6. Each member organization should submit a list of participants, including addresses, to the NHA no later than two weeks following the hill climb event.

Section 2: Insurance

  1. Organizations requesting NHA sanction and insurance must submit a non-refundable deposit of $100.00 to the NHA Secretary/Treasurer prior to April 1.

  1. All NHA sanctioned hillclimb events should be included in tallying year-end points.
  2. If a person becomes a member of NHA after the start of the racing season, points can only be credited from one event that took place that year prior to him or her becoming a member. If there were more than one prior event, the member can designate the event.

Section 5: NHA Vehicle, Equipment, and Driver Specific Safety Rules

  1. All competition vehicles must be fitted with a restraint belt system appropriate for their class (See solo/GCR Rules)

Roll bars/cages will be examined at technical inspection and must meet the appropriate solo/GCR and/or NHA criteria. NHA recommends all competition vehicles have, at a minimum an approved roll bar. NOTE: Open cars with factory installed roll hoops and/or factory (OE) aluminum/steel hard tops secured by factory (OE) mounting hardware will be allowed to run in street and touring classes only. Cars with retractable roofs will also be allowed in street and touring class. Fiberglass tops allowed with appropriate roll bar per NHA rules.
  3. A fire extinguisher or fire suppression system carrying a minimum 5BC rating is required in all competition vehicles. The extinguisher or actuating device must be within easy reach of the driver and/or safety officials.

  11. If an entrant in a Solo-Based class (a class not requiring a competition harness system) has installed an aftermarket competition seat, it is his/her responsibility to ensure that the restraint system holds him/her securely in the seat. Competitors are advised that, often the factory restraint system does not work with an aftermarket seat. The technical inspector will make the final determination as to the safety and suitability of the modifications.
  12. Effective 2018 all drivers in classes running racing slicks will be required to wear certified Hans devices per solo/GCR requirements. All other drivers will be required to wear foam neck supports/donuts.

NHA Administrative Safety Rules

  1. All member organizations must provide a pre-event driver orientation school for all drivers new to the event. This instruction should include course familiarization, basic rules, procedures, and special attention to know course hazards. All drivers should be encouraged to attend this instruction.
  2. All member organizations must ensure that all corner workers have received instruction including at least familiarization with equipment/supplies provided at each work station, ad radio protocol for the event.
  3. The NHA Safety Advisor at the event will check to ensure that NHA minimum requirements as listed below are in force.
    1. Minimum equipment at each work station will include a red or yellow flag, a fire extinguisher, and a radio.
    2. Work stations should be located so that competition vehicles are not out of sight on the race course for more than 10 seconds.
    3. First responder first aid kits shall be available at each event. A non-participating Certified EMT or physician trained in emergency care is required at each event. If an official equipped rescue vehicle is present, the presence of a first responder first aid kit is acknowledged.
    4. The member organization must have a vehicle present at the event that has communications equipment on board and can respond to an incident with appropriate emergency equipment.
    5. There will be no passengers in a competition vehicle while the vehicle is engaged in a timed run. The only occupant will be the driver.
    6. The event officials must have in place a system to ensure that all persons on the hill have signed a liability release form. NHA requires that a wrist band system is a part of this plan. In the case of minors, a parental signature is also required next to or immediately following the minor's signature.
    7. Drivers must be 18 years of age. NHA hill registration requires possession of a valid driver's license as legal documentation of driving privilege and classification.

NHA also does not allow any 2 wheel or 3 wheel vehicles for competition.
  2. NHA rules take precedence over all other listed rules.
  3. Event supplemental rules, as posted in pre entry information are next in precedence.
  4. Solo 2 rules, NHA special classes rules, GCR rules and NWR Vintage rules, will follow depending on which category the vehicle runs under. Should you have a question about your specific class you may contact the NHA Director of Classing by email (
  5. National Solo 2 classes as per SCCAŽ Solo Rules (Refer to Section 3 and sections 12 thru 18 for classes, specs and allowable modifications).

Since we voted to run Solo classes we also voted to run Open and Ladies this season.

NOTE: All Cars in Prepared and Modified classes per NHA rules must run a SCCAŽ GCR legal roll bar or roll cage. Hans devices will be required in 2018 for all drivers in these classes. The above classes are regular autocross classes like you run all the time at home so you should be able to properly class your car.

Starting in 2017 all drivers will be responsible for proper classing of their cars. Tech inspectors will not be asked to help with that other than to verify tires. Their job is to make sure the cars are safe, likewise registration and NHA treasurer will not be doing that this year. It is the owner/drivers responsibility.

Section 7: NHA Recommendations

While nothing in the following is a requirement, the NHA suggests that all member organizations review the recommendations and consider implementation as appropriate for their events.

  1. NHA will not recognize hill records nor award Challenge trophies for competitors whose vehicles are known to have been illegal for their classes. It is recommended classifications at all member events be monitored closely for compliance. To eliminate confusion, it is recommended that all entrants write out their class rather than using abbreviations. (i.e. E Production, C Street-Prepared, Etc.)
  2. NHA will only recognize the first two runs each day for points and hill records, unless all drivers are allowed the same number of runs each day.
  3. Arm and neck restraints are key in reducing injuries and the severity of injuries, and are to be encouraged. Many sanctioning organizations are moving toward requiring certified neck restraints.
  4. NHA recommends requiring attendance at a drivers meeting before each day's racing commences.
  5. It is recommended that all hills provide for parallel ladies classes. Women have the option of competing in an open class or the Ladies parallel class. The intent is to encourage participation by more women.
  6. It is strongly recommended that each worker station have a minimum of two workers. One of the workers may be designated to be responsible for radio communication. The other worker must be physically capable of responding to an emergency, including carrying and using the fire extinguisher.
  7. Course workers should avoid wearing red or yellow shirts. Course workers should wear shoes that would allow them secure footing on rough terrain (i.e. no sandals or beach shoes).
  8. Any minors serving at worker stations must have approval of the event safety steward.
  9. It is recommended that, in conjunction with the orientation for drivers new to the event, a tour up the hill, with commentary, be provided for safety reasons.
  10. A copy of the insurance binder be made available at the event for examination upon request.
  11. If "pit motorbikes" are used, it is strongly recommended that the operators be required to, at the minimum, wear a bicycle helmet and conventional (lace-up) footwear for protection.
  12. It is recommended that the member organization have on hand a complete set of current Solo/GCR Rule Books.
