Welcome to the PA Micro Midgets

UPDATED!  2024 The Rules of Tech and Specs

Technical inspection assists PAMM and event officials in determining, in their judgment, eligibility to participate in an event. The technical inspection does not ensure, certify, or warrant that the vehicle or any part of it is safe or totally and ultimately compliant with all applicable rules nor does it in any way change the fact that the driver, crew members, and vehicle’s owner are ultimately responsible for the safety and operation of the vehicle and equipment.


The Chief Technical Inspector must approve every vehicle before it competes. A driver or entrant whose vehicle is not approved and who subsequently competes or who presents it for recheck without the corrections specified may be penalized or removed from the event for being deemed “Unsafe.”


The driver’s safety equipment (helmet, race suits, shoes, etc) does not have to be inspected at the same time the vehicle is inspected, but it must be inspected by or at the driver’s first event of each calendar year. 


Note: Vehicles which have been altered or damaged after they have been approved at event Tech Inspection are subject to re-inspection and re-approval.


If all items are considered “in order” a “Tech Sticker” is issued for the vehicle and Driver.  This sticker will be placed on vehicle by Technical Inspector.   All vehicles must display a Tech Sticker signifying successful completion of technical inspection to enter the events.


Andrew Ketterman

PAMM Chief Tech Inspector

Failure to Meet Minimum Inspection Requirements

Any vehicle failing to meet the standards required (by the organization holding the event) shall be barred from participation or be disqualified. The entrant of any vehicle initially failing to meet the requirements prescribed by the organization shall be allowed to remedy any deficiency and to resubmit the vehicle for inspection as the committee may direct.


Minimum Inspection Requirements

The inspection shall be conducted in accordance with standards prescribed by the organization. As a requirement, the following vehicle equipment shall be in proper operating order.


The rules and requirements of the PAMM provide a foundation from which PAMM Officials, the event organizers and safety stewards will implement a functional program of incident avoidance. These Rules are not all inclusive and additional safety supporting procedures may be developed and implemented during the event. Where safety is concerned, there is no excuse for knowing something to be wrong, or risk generating, and ignoring the situation because it is not spelled out in writing somewhere. Safety is not a game of semantics or rule bending. It must be a living program balancing the needs of a highly competitive Motorsport, with the realities of safety and risk reduction.


The minimum age of drivers will be determined in advance by the management of each track where PAMM is scheduled to appear. Track operators have the discretion to choose different insurers and thus encounter different insurance regulations. Drivers under eighteen (18) years of age are required to have a signed Parental Consent Form. The Parental Consent Form must be signed by a parent or legal guardian and must be received by the PAMM prior to participation by the driver in any event. It is the driver/car owner’s responsibility to check with the track or PAMM prior to any planned appearance if age is a factor.   The PAMM Requirements are listed below.


          500’s                    12 and up.                  

          300’s                    10 and up.                                       


Items of safety, here written or understood and accepted by racing participants are mandatory.  This will be the minimums and implies no guarantee to 100% safety. Drivers should take their safety and the gear associated with it very seriously. Drivers should ensure it is serviceable and fits properly. It is the responsibility of the drivers, owners, and mechanics, not PAMM or Host Track, to ensure maximum safety at all times.

Additional safety equipment or safety-enhancing equipment is always permitted and the levels of safety equipment stated herein are minimum prescribed levels for a particular type of competition and do not prohibit the individual racer from using additional safety equipment.


Under no circumstances, may any certified product be modified, altered, or in any way vary from the “as

manufactured” condition.

Each Driver is solely responsible for the effectiveness of personal safety equipment used during a PAMM sanctioned Event.   All mandatory safety gear is be worn any time the race car is attempting to fire the engine.

The removal of any safety equipment prior to exiting the racing surface is strictly prohibited. Any Driver caught in violation will be issued one warning. The next infraction will result in disqualification from the Event and points will be forfeited for the Event.


It is the responsibility of the Participant, not PAMM or any Track, to ensure that all safety equipment is approved and is correctly installed, worn, maintained, and used.  Unauthorized cars, parts, and/or equipment will not be considered approved by reason of having passed through technical inspection at any time, or any number of times.  Moreover, having passed through technical inspection at any time, or any number of times, is not a defense to a violation found on further inspection.


Cars must meet the conditions of the construction specifications to be eligible for competition at the Host Track.

Prior to participation in any PAMM Sanctioned event, all cars are subject to a safety inspection. Any cars that have not been inspected during the allotted inspection time, must be inspected before warm ups start or they will not be eligible to participate in the race.


Cars found to be unsafe shall be rejected until such time as the officials are satisfied that changes or corrections and/or repairs have been made to ensure required safety standards.   Only cars deemed suitable for competition will be approved for participation. Track/PAMM Officials reserve the right to reject any entry for failure to comply with safety or technical rules as set forth by PAMM and Host Track.


Tech Official will have final approval of a race cars legality and safety for any and all classes. The Tech Official will have the right to call for a re-tech and/or disqualify any vehicle that they feel does not meet the safety requirement. (Refusal to comply with a re-tech - will be automatic disqualification). Tech officials may reject vehicles that are improperly prepared at any time during the event.


Approval of any race car by an Official shall mean that the race car is approved for participation in the event and shall not be construed in any way to mean that the inspected vehicle is guaranteed to be mechanically sound or safe. Be it further declared that Officials and/or the PAMM shall not be liable for any mechanical failure, nor for any losses, injuries or death resulting from the same.


Any one driving race cars and/or any other equipment erratically or excessively fast through the pit area will be dealt a penalty at the discretion of the Officials. At the discretion of Officials overseeing an event, any participant may be disqualified by the official(s) for violation of any PAMM rule, equipment and/or conduct deemed to be hazardous to other participants or officials.


If an Official observes any inadequacy in a competitor's race car, equipment, or conduct, the Race Director may take whatever action he or she deems necessary to correct such inadequacy. Such action may include, but is not limited to car or Driver disqualification and/or suspension.   The Official’s interpretation of these rules shall be accepted as binding.


Drivers must remain in their cars. Any Driver getting out of their car will be disqualified from the race. Any Driver involved in a red flag may exit the car to assess damage only.


No Driver may exit his/her car on the race track unless there is an Official or designated individual present to grant permission to do so. If a Driver is involved in an on-Track accident and needs to be towed or pushed off of the Track, the Driver must remain in the vehicle until an official indicates to Driver that it is safe to exit the race car.


Upon exiting the car, Drivers must remain with their cars to accompany them back to the pit area. The only exception to this rule will be in the event of a fire, a similar emergency/safety situation occurring or refueling is occurring.

No one is permitted on the race track at an accident aside from the track safety crews & track officials.


Anyone involved in an accident on the track or in the pit must report it to the track office and/or call the track to fill out an accident report. Insurance carrier needs a report before any payments will be made.


Any Driver who exits their race car on the Track in order to confront the Driver of another car and/or to show displeasure with another Driver will be subject to a fine and or suspension to be determined by Officials.


The speed limit in the pit area is 5 MPH. No burnouts are allowed on the return road or in the pit area.
