MIDWEST DASH 2023 COMPETITION RULES

We expect the same thing from all our drivers and teams. Please keep your cars looking clean and professional. All cars must be clean, complete, and maintain all body panels, including bumper covers, fenders, doors, quarter panels, and deck lid/hatchback at the start of every racing event.

All cars must have clearly legible, minimum 5” tall numbers on upper right (passenger side) of the windshield. Cars must have drivers name on each side of roof openings.
Midwest Dash Series encourages and welcomes local/home track drivers to compete with our series regulars. Tracks local/home track rules may be similar but differ from the Midwest Dash rules. In the spirit of competition, Midwest Dash officials MAY grant a temporary waiver for eligibility to the local/home track cars. Any rules, compliance exemptions, or waivers granted in this context will be at the sole discretion of Midwest Dash series officials. Penalties, point forfeiture, or payout adjustments may occur for cars that are deemed by Midwest Dash officials to have a performance advantage relative to regular Midwest Dash legal cars. All regular series participants will be required to be in full compliance with all the Midwest Dash rules set forth with no exemptions or waivers granted

Drivers and teams are always required to allow complete and unfettered access to their racing vehicles by any MIDWEST DASH official for the purpose of inspection and rules compliance. Any attempt by a driver, team member, or team representative to limit access to a race vehicle, or to conceal a rules violation from MIDWEST DASH officials, will result in immediate disqualification regardless of the condition of the race vehicle. Disqualification can include: a change in heat race or feature starting position, a change in on-track racing position during a race, a change in heat race or feature race finishing position, or expulsion from the racing event or racing series.
Whenever ordered by any MIDWEST DASH officials, the driver is required to present themselves and their car to the inspection area determined by MIDWEST DASH officials on race day. This order may come in form of a verbal notice during the driver’s meeting, a verbal notice directly from MIDWEST DASH officials, a notice via radio transmission (Raceiver, etc…), or by hand signals or gestures from MIDEST DASH officials.
IT’S THE RESPONSIBILITY OF THE DRIVER TO KNOW WHEN AND WHERE THEY ARE REQUIRED TO REPORT TO THE TECHNICAL INSPECTION AREA. Failure to report DIRECTLY to the technical inspection area when required will be considered a deliberate attempt to conceal a rules violation and will result in an AUTOMATIC DISQUALIFICATION.
IT’S THE DRIVERS RESPONSIBILTY TO BE READY AND KNOW WHEN THEIR PRACTICE, QUALIFYING, AND RACE IS TAKING PLACE. We cannot and will not hold up the show and will not make any special accommodations for practice or qualifying.
Any driver required to report to the technical inspection area that deliberately stops or visits their or any other teams pit area, or while in route to the inspection area will be DISQUALIFIED (NO EXEMPTIONS). All race drivers required to report for technical inspection, are required to maintain their race vehicle in the EXACT same condition as was during the race, from the time the vehicle completes the race until technical inspection by MIDWEST DASH officials is completed. Any part removal, part installation, or adjustment to the race vehicle prior to and during the technical inspection process that is not authorized by MIDWEST DASH officials, is considered illegal and result in immediate disqualification.
During any cars technical inspections (start of the night, post qualifying, or post race), only the driver and a maximum of one crew member belonging to each race car will be permitted in the inspection area. Any driver or crew member not belonging to the cars being inspected are required to maintain a minimum distance of 15 feet from the cars being inspected. No driver or crew member may refuse, attempt to delay, or in any way limit or prevent MIDWEST DASH officials from performing technical inspections. Violations of these rules will result in the offending team being disqualified.
Drivers disqualified from an event will be subject to loss/forfeiture of event championship points, applicable events starting pay, tow money, and event purse payout as determined by MIDWEST DASH and the race director. All decisions by the MIDWEST DASH officials on payout, scoring, and penalties are final.
Drivers MUST remain with any disabled car to assist track personnel in removing the car from the racing surface and returning the car to the pit area. Drivers with a wrecked or disabled car may not exit their car until instructed to do so by a track or safety official, unless the driver is in direct danger of physical harm (such as fire, leaking fuel, smoke in the cockpit, fumes, etc…). Drivers leaving their cars to confront another competitor or race official will not be tolerated. Obscene gestures and profanity will NOT be tolerated. Any driver that leaves their vehicle without the permission of MIDWEST DASH officials or track safety personnel will be penalized or expelled. Any crew member that approaches the racing surface for the purpose of confronting a competitor or racing official will be penalized or expelled. Any crew member or family member coming onto the racing surface without permission of MIDWEST DASH officials will be expelled from the event’s premises. Penalties for improper conduct may also include fines, suspension from racing events, and or expulsion from the racing series.
Our Technical Inspector(s) word is final on car safety, person safety equipment, and cars meeting these rules. If a Technical Inspector finds something that needs to get fixed, fix it. If a “grey area” is found or may need to implement a penalty, the Technical Inspector will come to management and we will work together to come up with a decision and solution. Do not go to management if you are told something needs to be done or fixed on your cars. If anyone, driver, crew member, family member, or team representative yells, argues, curses, or gestures anything in any way to our tech officials, that team will receive a penalty and/or may be disqualified for that event. Being a tech official is a hard and thankless job and they are there to make sure everyone is safe and is on a level playing field.
MIDWEST DASH has set these rules to keep everyone safe and as equal as possible for great competition. MIDWEST DASH reserves the right to modify, change, alter, or discontinue all or any of these rules in the interest of competition and safety. We want the best show possible for our associate tracks and for the fans.
