Detailed Rules
THSCC Autocross Rules
last revised 2/3/2017
1. | General Rules |
| ||
| 1.1. | In the case of questions regarding safety, protests, or any issue regarding general rules, the THSCC President, Autocross VPs, and Event Chairs will be involved in the decision. They may ask for input from anyone else not involved in the question. If one of them is involved in the issue, they will remove themselves from the discussion. Involved parties will be allowed to offer their input. | ||
| 1.2. | If, for some reason, disciplinary action must be taken, all club officers present at the time of the incident will decide upon the correct action. While no fines may be levied, the officers may ask the offending party(ies) (whether a competitor or spectator) to leave the present event, may ban the offending party(ies) from a number of events, or may request that the offending party(ies) never participate/be onsite again. Except in the first situation above, a special meeting will be called to more fully discuss the later options. All club officers should attend. Any club officer involved or related to the individual(s) involved will excuse him/herself from the meetings. If it is decided that a person should be banned from all future events, a letter drafted by the club President will be sent to that person. The letter will contain details of why this decision was reached. The banned person may ask that this decision be reviewed annually. | ||
| 1.3. | Event Chairs will be responsible for making any decisions or clarifications regarding the running of their specific event. Event Chairs, after consulting with the Autocross VP's and club President, will determine the number of runs for the particular event. They will also determine if fun runs will be done after the event. At the discretion of the Event Chairs, in consultation with the Autocross VPs, the number of runs announced at the Drivers' Meeting may be raised or lowered during the course of the day. Announcement of the change should be made over the P.A., spread as widely among competitors are possible, and the Starter should also be asked to relate the announcement to drivers at the start line. Competitors should also help spread the word among themselves. | ||
| 1.4. | On event setup days, only Event Chairs, or drivers selected by Event Chairs, may run the course. It is desirable that the driver performing the safety preruns be someone who is not going to compete in the autocross. For NCAC events, the driver peforming the safety check should not be competing in the series. | ||
| 1.5. | No alcohol, drugs, or any controlled substances may be consumed anywhere on the site during the event. An event starts when registration opens and ends when the last run is made and the course is picked up. | ||
| 1.6. | All people who are on the site must sign the insurance waiver. This includes all participants, spectators, and crew. Participants are responsible for having their family members, crew, or friends sign the waiver and wear a wristband issued for that event, which indicates such. An announcement will be made by the Event Chairs at the Drivers' Meeting pointing out this rule. It is the responsibility of all participants to prevent anyone without a wristband from entering the course area. | ||
| 1.7. | The course may be (and should be) walked as many times as desired before the Drivers' Meeting. Only walking is allowed. This rule is intended to keep people from riding bikes, skateboards, scooters, or any other type of wheeled apparatus during the walk through. One exception, wheeled devices may be used at walking speed if they are being used as a mobility aid. | ||

|
2. | Eligibility of Participants | ||
| 2.1. | Participants must have a valid driver's license at the time of the event and must be prepared to present such license during registration. Learner's permits are not acceptable. | |
| 2.2. | All participants must be 18 years of age, OR if under age 18, must have a THSCC Minor Release Form signed by a parent or legal guardian. Such form is to be presented and signed off by the club President, Sr. Vice President, or an Autocross VP, then turned into the Registrar. A valid driver's license is still required. (Minor Release Forms must be kept on file with insurance waiver forms). | |
| 2.3. | THSCC reserves the right to refuse to allow anyone to participate if it is not possible to verify the above qualifications. | |
| 2.4. | Passengers under 12 years of age are not permitted in any runs on course, including fun runs. Any exceptions must be specifically approved by the club President, or in his/her absence, the highest ranking club officer present at the event. | |
| 2.5. | Non-novice participants may take along any other participant on timed runs, they may also take along spectators who have signed the ride-along waiver. Novice drivers may only take along THSCC approved instructors on timed runs; novices may not take other novices on timed runs. A novice is considered to be anyone having participated in 3 or fewer autocrosses OR still running in Novice Class. Any exceptions to these rules must be specifically approved by the President, or in his/her absence, the highest ranking club officer present at the event. | |
|

|
3. | Safety and Car Preparation | ||
| 3.1. | It is the responsibility of the driver to ensure that his/her vehicle is properly prepared and safe for competition. | |
| 3.2. | Speed through the pits will be no more than 10MPH. No tire warming, brake warming, or other high speed maneuvers will be allowed anywhere on the event sight! Pits are defined as starting at the first cone for the course and ending 20' beyond the last car, or its trailer/tow vehicle, entered in the event. Violation of these rules will be grounds for asking a competitor to leave the sight. | |
| 3.3. | All cars that have not received an annual THSCC tech inspection must pass a minimal tech inspection at each event. The inspection is to be performed by one of the THSCC Tech Inspection Crew. If the car has a THSCC Annual Tech sticker, it does not need to be teched again at the event by a THSCC Tech Inspector, as the car owner has already stated that he/she will be responsible for doing his/her own tech inspection prior to each event. If the car needs to be teched, inspection will only be done after the driver(s) have registered. Once tech inspection closes (typically 15 minutes before the Drivers' Meeting) cars will be teched as time permits. However, each driver will get the same number of runs as other competitors in class. | |
| 3.4. | Sunroofs must be securely attached to the car or completely removed from the car. | |
| 3.5. | All loose objects must be removed from the car and trunk. Spare tires may be left in if secured. | |
| 3.6. | Helmets and seat belts must be worn on every run by every person in the car. This includes fun runs and runs during setup days. | |
| 3.7. | At a minimum, the driver's window must be all the way down. Both sides is preferable. Exceptions may be made for runs made during heavy rain. | |
| 3.8. | During runs, drivers and passengers, if any, must keep arms and hands inside the car. | |
| 3.9. | Car class and numbers (of the size and type specified on this website at Car Class Letter and Number Specifications) must be displayed on both sides of the car. If a car has more than one driver, all drivers are responsible for reporting to the Starter the correct class and number. The THSCC Scoring Team will not be responsible for correcting errors that occur in scoring due to improperly marked cars or unreadable class/numbers. | |
| 3.10. | We use SCCA Guidelines on helmets. No DOT only rated helmets will be allowed. All helmets must be inspected annually by the Chief of Inspections and have a current inspection label applied on the left side. The starter will check for the label before a participant may run the course. | |
| 3.11. | Effective November 10, 2004, THSCC will have and enforce a 100 dB sound limit at all of our autocross and rallycross events. For some sites, this limit may be reduced to 95 dB, which will be indicated in the event information. All cars are subject to being tested at any place on course, and measurements will be made at approximately 50 feet from the course. Any car which is found to be in excess of the sound limit will not be allowed to start any subsequent runs. This rule is necessary to preserve our relationship with our sites. | |

4. | Preregistration | |||||||
| 4.1. | If at all possible, licensed drivers wishing to participate should preregister and pay for an event via www.Motorsportreg.com | ||||||
| 4.2. | You can pay for an event:
| ||||||
| 4.3. | Online preregistration usually closes at 8:00pm on the Thursday prior to each event. Occasionally, extenuating circumstances require preregistration be closed earlier. Announcements via the club meeting, club forums, club email list, and/or club website will be made as soon as possible if there is to be a change to the usual preregistration deadline. | ||||||
| 4.4. | If you preregister for an event and later discover you will not be able to attend the event, please unregister yourself prior to the cutoff date! There is often a waiting list for the event and your unregistration will allow the first name on the waiting list to automatically move into the event. | ||||||
| 4.5. | Refund/Cancellation Policy for preregistrants: Once registered, your payment will not be processed until after checking in on the morning of the event. If you do not attend you will not be charged. | ||||||
| 4.6. | THSCC events are for club members only, participants must have a current, valid, annual or lifetime THSCC membership. | ||||||
| 4.7. | Unless otherwise specified, the entry limit for THSCC events is 130 participants. THSCC is committed to giving each participant at least 4 runs per event; entry limit is assessed per event on factors e.g. site size, site layout, and amount of daylight. | ||||||
|

5. | Event Day Registration | |||||||||||||||||
| 5.1. | All competitors must check in at the registration desk (usually in the bus) before registration closes, even if pre-registered. After registration closes, usually 9:30AM, a $10 fee will be charged. | ||||||||||||||||
| 5.2. | Competitors must be prepared to show a valid drivers license at registration. | ||||||||||||||||
| 5.3. | During registration, each driver must designate in which one class he/she is running for points. A driver may register for a second set of runs, subject to the following limitations:

|
|
6. | Worker Assignments | ||
| 6.1. | Each driver must work during the event. Any driver who cannot physically work the course should check with the Worker Coordinator prior to the start of the event to see if there is a non-course worker position available. If not, he/she may be able to arrange with the Worker Coordinator to have someone work the course for him/her. Any participant who does not work will receive a DNW (Did Not Work) instead of times in the results, will not receive THSCC points for the event, and will be required to work prior to running at the next THSCC event attended. Multiple offense will result in the competitor being banned from future THSCC events. Read more about working here. | |
| 6.2. | Only competitors entered in the event will be allowed out in the course area. Exceptions may only be made by Event Chairs, Autocross VPs, Sr. VP, or the President. | |

7. | Event Scoring and Classing | |||||||||||||||

| 7.2. | Car classifications and bumping order will follow the SCCA® rulebook for the appropriate year. | ||||||||||||||
| 7.3. | Points are only awarded to a participant that completes at least one run. DNFs do not count as completed runs. | ||||||||||||||
| 7.4. | Five cars or five minutes minimum must exist between a competitor's runs. If a competitor is awarded a rerun, these same guidelines will also be followed. For reruns, a competitor may choose to go to the end of the line or may ask another competitor to be allowed to break into line -- as long as the 5-car/5-minute rule is followed. | ||||||||||||||

|
9. | Handling Aborted Runs and DNFs | ||
| 9.1. | A car that starts its run but does not or is unable to complete the entire course will be scored a DNF for that run. Once a car crosses the start line, the run is officially started. In other words, a car that is in the start box, starts to move forward when given the OK by the Starter but breaks before crossing the start line has not officially started a run and will not be given a DNF. Once the car crosses the finish line the run is over. (This last part seems obvious but it is intended to clarify any situation where it is possible to hit the finish line before finishing the course. For instance, miss a turn and wind up unintentionally in the finish box.). Chances are that a novice will ask you something you don't know the answer to unless you read all of the rules. | |
| 9.2. | If, during a run, a participant sees a cone out of place, he/she must bring the car safely to a stop on course and point out the cone or cones. After this is done and the course worker acknowledges this, the participant will drive to the finish line as specified in the rerun rules. The participant will be issued a rerun. This rule does not apply to a cone moved by that driver during an earlier part of his/her same run (i.e. on sections of the course that a driver must cover twice during a single run). | |
| 9.3. | If a cone is knocked down by a driver on the first pass of a section of the course that is used second time on the same run, and the cone has not been reset by a course worker due to insufficient time between the two passings of the same car, no rerun will be issued. In this case, the competitor will drive the line that was originally marked by the cone. No extra cone penalty will be given if the downed cone is hit because it is in the line. The reason for this rule is to keep a competitor from gaining an advantage because of a knocked down cone and to protect the course workers. | |
| 9.4. | For a timer malfunction or other situation resulting in a rerun, the car on course should be red flagged as soon as is safe and possible. The car should proceed at reduced (but not creeping) speed in as direct a manner as possible to the finish line without following the course. | |
| 9.5. | A car that is red flagged for a safety issue will be given a rerun. Safety should always be the primary consideration by all course workers. If a competitor's car develops a mechanical problem that may cause a safety problem, even if the car is capable of finishing the run, the driver should be red flagged. Because the red flag was for a safety problem and NOT the mechanical problem, the competitor will get the rerun. | |
| 9.6. | Anyone damaging the timing equipment or hitting the large cones by the timing equipment will be given a DNF for that run and will be responsible for the costs of replacing/repairing the equipment. | |
