On-Site Text Messaging
To sign up for on-site text messaging, text 22OSP to 833-345-2423. Signing up for the text messaging system is highly recommended as it is used by the on-site event staff to notify everyone about any updates or changes for the event. They also help keep you up to date on what run group/run number is currently on course.
A. GENERAL RULES: This event is held under the SCCA Solo Rules and SCCA ProSolo National Series Rules, plus the rules and procedures found on this event page, using all Open, Open Index, and Ladies Index National classes and National Supplemental classes, as defined by the 2022 ProSolo Rules. All class changes must be approved by the Chief Steward or their designee once check-in closes.

- A speed limit of 12 MPH will be enforced at the event site including pre-grid and grid. Tire spins, rapid speed or direction changes, or other "abnormal/unusual" driving techniques are strictly prohibited throughout the event site, other than during competition. See Event Chairman for questions or problems.
- No tire warm-ups are allowed anywhere on the site, except in the designated start area (green cones).
- Drivers must always operate their vehicle(s) in a safe manner, including exiting the course. Driving in an "aggressive" manner deemed unsafe and observed by an Event Official will be handled with severity by the Chief Steward. Such actions are NOT protestable.
- Drivers are responsible for the actions of their crew and guests.
- Photographers desiring to enter a course area must be approved by the course Safety Steward and be accompanied by a spotter. A minor may not serve as a spotter.
- The operation of motorized vehicles, whether gas or electric powered, such as but not limited to, golf carts and other personal transportation vehicles, is limited to persons who can present a valid driver’s license.
- Pylons, tape, and/or other barriers will define "No Parking" areas near the course. Cars parked in such a manner that block or restrict defined driveways or entrances to course areas will be towed away without notice, at the expense of the vehicle operator/owner.
- Skateboards, hoverboards, Segways, bicycles, and similar conveyances may not be ridden in the Grid area.
- All incidents involving injury and/or property damage occurring on the event site or felt associated with the event will be reported as soon as possible to the Event Chairman or Chief Safety Steward.
E. ORDER OF RUNNING:
- Competition will be on two successive days with the event subdivided into three (3) heats, plus the Challenge competitions.
- There will be an A grid and a B grid. Drivers are to position their cars in the grid as assigned. The car must be in the specified grid position no later than 5 minutes prior to the scheduled start time for Heats 1 & 3 (Group 1) or prior to the Grid line being activated, which is defined as the drivers at the beginning of that Grid line being directed to the Stage Lines (Groups 2+). If a driver is not in their grid position by the deadline, they will be penalized with a DSQ of their second run on each side (PS-2) or the last run (PS-1) for that Heat.
- All drivers will be assigned a "home" space number for grid purposes where they may leave any necessary equipment. Do not block the access lanes between spaces. There will be a designated Second Driver Grid area.
- Heat assignments will be posted on the event page on the SCCA website – SCCA.com–. It is your responsibility to know when your car should be in grid.
F. PENALTIES FOR INCORRECT NUMBERS OR BARCODES:
- Competitors at the start line with the wrong number on their car, 2 sets of numbers, or the incorrect class showing will receive a warning for the first offense, a cone penalty for the second offense and may receive a DSQ for three or more offenses at the same event.
- Competitors at the scanner with more than one (1) barcode showing on the helmet will receive a warning for the first offense, a cone penalty for the second offense and may receive a DSQ for three or more offenses at the same event.
- A driver at the scanner or the start line without the appropriate helmet decal (Solo 2022) will be directed to exit the stage lane. Go directly to the Tech/Impound area to get the helmet inspected and decal applied.
G. MINIMUM CLASS SIZE: Refer to ProSolo Rules Rule 20.8.C
- If any Open Class does not have the minimum of five (5) drivers entered and checked in by the close of registration on the evening before class competition begins, they will be bumped into the Bump Index Class for Super Challenge eligibility.
- If five (5) entered and checked in drivers do not make a start in class competition, the class will be moved into the Bump Index Class at the earliest administratively feasible point in the competition, which may be after Heat 1 runs.
G. PROTEST AND APPEALS: Refer to ProSolo Rules Rule 20.10.P and ProSolo Rules Rule 20.10.Q
H. COURSE MARKERS: Refer to Solo Rules, Rule 7.9
I. RESULTS: Provisional results will be posted in impound after completion of all runs for the heat. Results will be final 30 minutes after provisional results are posted. Check final results to make sure the manufacturer is correct for your car and tire brand. Official results will be available on the event page at www.scca.com.
J. TROPHIES AND AWARDS: Trophies will be awarded on Sunday (2nd ProSolo competition day on a multi-event weekend) after the last runs of regular class competition in Impound. They will not be mailed. If you leave the event early, appoint someone to receive your award.
K. EVENT SCHEDULE: Actual schedule may deviate from the published schedule due to unforeseen circumstances during the event. It is the driver’s responsibility to listen to the PA system, refer to event text communications, and pay attention to activity on course.
L. COMMUNICATIONS: Please sign up for text messages for on-site communication by the event officials. Sign up by texting the event keyword to 833-345-2423. The event keyword, once established, will be found in the "Location & Site Details" dropdown and in pre-event communication. Announcements will also be made over the PA system. Live timing can be found at sololive.scca.com.
A. DRIVER ELIGIBILITY: Refer to ProSolo Rules Rule 20.6
B. DRIVER MEETING NOTES: There will be a Novice Meeting at the Right Course Start Line on Saturday morning. Review the event schedule for the time. Changes to the event details and other items of information as well as the names of all event officials will be included in the material provided on the event page at SCCA.com. IT IS A COMPETITOR’S RESPONSIBILITY TO CHECK THE EVENT PAGE AT SCCA.COM FOR CHANGES TO THE SUPPLEMENTAL REGULATIONS.
C. ENTRANTS AS WORKERS: ProSolo Rules Rule 20.10.D
Early work assignments that offset a normal work assignment must be pre-approved by the Event Chairman and/or staff. These assignments must be extremely limited to prevent loss of critical support during the event. Serving as a volunteer prior to the event is greatly appreciated and a key element in the success of this event. However, this does not automatically offset a normal work assignment.
D. WORKER MEETING NOTES: Workers will report to the Worker Chief at the Lincoln Drivers' Center (Tech Trailer) during the middle of the last group that is running prior to their assigned work shift. Shift A workers will report 20 minutes prior to the start of the event. Failure to report on time will result in an additional work assignment after the finish of the last shift on that day. Not complying with these rules will result in disqualification.
It is possible that your work assignment within your shift may have changed due to cancellations or class changes. A flag will be raised at the Lincoln Drivers' Center to let you know it is time to check in and that someone is available to get you checked in. Specialty areas (Grid, Timing, Impound, Sound & Safety) will check in with their chiefs.
The worker sheet will be posted at the Lincoln Drivers' Center and on the SCCA event page online when check-in closes so competitors can verify work assignments. It is your responsibility to know when you should report for your work assignment.
A. VEHICLE ELIGIBILITY: Competition is open to all vehicles conforming to the Open, Open Index, and Ladies Index National classes and National Supplemental classes, as defined by the 2022 ProSolo Rules.
- The Tire Rack® is the title sponsor for all 2022 SCCA® National Solo® events, including National ProSolo® events. Participants in these events are required to run the title sponsor decal, which is a windshield decal that is to be used at the top of the windshield. Vehicles without windshields or with plastic windshields may place the decal on the front of the car in a highly visible location approved by the Chief of Compliance. Decals other than the official Tire Rack® decal, except those required by ProSolo Staff, are prohibited on the windshield.
- Additional required event decals are one SCCA® with wheel (on the front bumper area) and 2 ProSolo decals (one on each side).
C. TECH PROCEDURES:
- Safety Inspections (Solo Rules 3.3.3) should be completed at the event site and will be completed by competitors using a Self-Tech form.
- Solo Rules 3.7 Vehicle Identification will be checked. The official Tire Rack decal and tech stickers are the only decals permitted on the windshield
- Competition vehicles that have a required minimum weight (Street Modified, Prepared, Modified, CAM, and Kart) will inform Tech of that weight so the weight and vehicle wheelbase can be posted on the tech sticker. This is to allow other competitors to know the declared minimum weight and to reduce any delays at the scales during event impound procedures.
D. IMPOUND PROCEDURES:
- All competition vehicles will be impounded per ProSolo Rules 20.10.K to assure that competitors have complied with the SCCA National Solo Rules and the Supplementary Regulations for the event. Car information verification will also be conducted in Impound.
- Vehicles will be impounded following the completion of each Heat until released by the Chief of Impound, their designee, or the Chief Steward. The driver of each vehicle or a designated representative must remain in the impound area near the vehicle during the impound period. Karts will be allowed to be driven to the scales under close supervision by event officials. Impounded vehicles may be held until the results are audited.
- ProSolo officials reserve the right to inspect any or all cars to verify conformance to the rules. Drivers should be prepared to show documents of their vehicle specifications and to assist in the verification of vehicle compliance with these specifications.
- Competitors may observe but Impound inspectors must not be hindered in their assigned duties by anyone in any way.
- Impound does not act on hearsay information regarding competitor concerns. If competitors suspect a rule violation, they should file protests in accordance with the National ProSolo Rules. Rule 20.10.P, Protests.
- Classes that have minimum weights are required to be weighed. It is the competitors’ responsibility to know if their vehicle has a minimum weight requirement.
E. SOUND POLICY: Refer to Solo Rules Rule Appendix I. Sound requirements are strictly enforced.
Rationale: Members are asked to realize that sound level measurements are designed to help us be good neighbors to those that work or live near our events. It is not intended as a "gotcha!" to catch drivers unaware. All competitors should come to the event in good faith with appropriate equipment keeping sound levels below the limit. Intentionally "pushing the envelope" of sound levels is in poor taste and puts our sites at risk.
Exceptions to Appendix I of the Solo Rules, 2nd and 3rd paragraphs:
If a vehicle exceeds 97 dBA on any run during a heat, the Sound Steward or their designated representative will notify that driver of any measurement over 97 dBA in Impound after runs are completed for that heat. (2-driver cars are considered as 2 individual cars.) If a vehicle exceeds 100 dBA on any run during a heat, that driver will be allowed an attempt to reduce the sound level of the vehicle before their next heat. (A "time-out" per ProSolo rules section 20.10.H.15 may be used.) If a viable remedy has been attempted in the judgment of the Sound Steward or representative, the driver will be allowed to run in their next heat. If the driver declines any "repair action" or the "repair" is deemed inadequate by the Sound Steward or representative, the driver will forfeit all subsequent runs in that vehicle (unless an adequate "repair action" is completed before the next heat). If the vehicle exceeds 100 dBA again during a run in any subsequent heat, that heat will be scored DSQ (disqualified) for all runs. If a sound violation incurs a DSQ for a heat, any rerun(s) taken will also be DSQ and the sound-based DSQ will stand. The number of reruns taken will be subtracted from the next remaining heat.
F. TIMING AND SCORING: Refer to ProSolo Rules Section 20.10.J
- Class finishing positions will be determined by combining the best corrected time (or corrected index time for Index classes) from each course during the class competition, which will normally consist of two (2) runs per side per Heat.
- Official times will be posted following the completion of each class session. Any initial questions about these results should be directed to the Chief of Impound or designate. THE TIMING & SCORING TRAILER IS OFF LIMITS FOR COMPETITORS, CREW, AND SPECTATORS unless invited to enter by an event official.
- Live timing is available at sololive.scca.com.
You must register for contingencies each year through the SCCA website, prior to competing for all Silver Gold, and Platinum contingency programs. In some cases, you'll need to register with the sponsor as well, so please read each program's registration requirements carefully. Decals will be available at tech inspection during each event. Bronze programs require registering and receiving decals directly from that sponsor, please refer to the program descriptions for more information.
Registration Policy (after online closes)
Online registration closes at 3:00 pm Central, Tuesday prior to the event. After online registration closes, you can still register for the event on-site during regular registration times on the day prior to the competition. Please note, there will be a late entry fee imposed on all on-site registrations. If the event is already full we will follow the waitlist policy (see below).
Car Number Policy
Car numbers selection will be on a first-come, first-served basis. Only one- or two-digit numbers will be allowed (i.e., 1 through 99). Exception: Where there are two drivers in one car, in one class, then the second driver MUST be 100 plus the first driver's number (99 and 199). The Motorsportsreg.com system does not allow drivers to reserve their co-driver's number. With that, if there is a conflict where someone signs up for a number and someone else who is not the co-driver signs up for the corresponding number, the person that signed up first for either the two or three-digit number is the owner of that combination. If you notice a discrepancy in numbers, please contact Nikki Edwards (firstname.lastname@example.org). Motorsportreg.com provides the date/time of registrations to determine who registered first and is the rightful owner of the number combination. If desired, drivers of the same car but in different classes (open and ladies) may use the same car number. Drivers of the same car in the same class must submit separate entries. Car numbers above 199 are not allowed at National Solo events.
All cancellations must be made in writing.
Please contact Nikki Edwards (email@example.com) with questions or to cancel.
Please review valuable information regarding refunds below.
Partial refunds (SCCA keeps $50) for cancellations IF:
Entrant cancels PRIOR to 7:00 pm Central the day of on-site check-in.
NO REFUNDS for cancellations IF:
Entrant cancels AFTER 7:00 pm Central the day of on-site check-in.
The Tire Rack SCCA National Solo events (ProSolo, National Tour, CAM Challenge) are adopting a revised waitlist policy for 2022:
- The initial entry cap will be set 15 entrants lower than the final cap.
- When an event hits the initial entry cap, the remaining competitors will be put on a waitlist.
- Just like the 2021 Tire Rack National Solo season, the waitlist will be published to show the order in which each member is on the list, based on the order of entry receipt and the timestamp listed on the MSR registration. This is the order in which entries will move off the waitlist and into the event when a cancellation is processed. This list does not automatically update in real-time but is rather a report from the registration system that will be run periodically so that those on the waitlist can understand their current position. Given that the list is not updating in real-time, there may be names at the top of the waitlist that has already moved into the event and there may be names that have registered onto the waitlist that do not yet appear.
- When 15 entrants have registered with the region of record of the hosting region the cap will be increased to the final. If 15 hosting region members have not registered 2 weeks prior to the event the cap will be increased to its final.
- For entrants on the waitlist, there is no guarantee the entrant will get into the event.
- As entrants on the entry list cancel, the next person in line on the waitlist will be notified via email that there has been a cancellation and they have now been moved into the event. When that entrant is moved over, they will be required to log into MSR and pay for the event (MSR does not charge waitlisted competitors). The entrant will have 24 hours to pay for the event before that entrant is placed back on the waitlist and the next entrant is put into the event.
- We will continue to move entrants off the waitlist as we receive cancellations up until the time online registration closes.
- After online registration closes, we will not update the waitlist online. However, if there is a cancellation after online registration closes, entrants on the waitlist will be contacted in waitlist order to let them know a spot in the event has opened. They will be instructed to contact the on-site event Administrator to claim their spot and remit payment. The waitlist will also be printed and posted in the timing trailer on Friday morning. As cancellations come in during the registration/check-in day, we will try to contact the top person on the waitlist to see if they are available and still want to get into the event that day.
- At the end of registration on the day prior to the competition, the waitlist will be closed, and no new entries will be allowed into the event.
Onsite Event Registration and Car/Class Changes
For any event that is not sold out, on-site registration is allowed on the day prior to competition. All on-site registrations will be charged the event late fee (see event registration page for pricing). Car and class changes are allowed at check-in on the day prior to competition. Any car or class changes on the days of competition require the approval of the Chief Steward for the event.
These strategies, guidelines, and information are in concert with the SCCA COVID-19 Event Guidelines posted on the SCCA website and will continue to evolve throughout the season as we gain knowledge and experience.
- Social/Physical Distancing
- PPE: have a mask available
- Minimize Contact
SCCA COVID-19 Guidelines: https://www.scca.com/pages/covid-19-event-guidelines
Competitor Pre-Event Preparation
- If you have symptoms, PLEASE STAY HOME to protect the Solo Community!
- Review this document and the SCCA COVID-19 Guidelines.
- If possible, bring your own PPE (mask, sanitizer, etc.).
- Bring your own food and water. Community water coolers will not be provided.
- Bring a helmet; loaner helmets will NOT be available.
- If there is a change to your registration, make it in advance to avoid lines on site. Changes can be made online until online registration closes. After that, changes should be emailed to Nikki Edwards at firstname.lastname@example.org.
- To help minimize contact at the event, please sign up before the event for the SCCA Annual Waiver at https://my.scca.com OR be sure to sign up for the Speedwaiver when you register for the event or receive the event email.
General Guidelines and Information:
- Follow your appropriate guideline as laid out in the SCCA COVID-19 Guidelines linked above.
- When space is available, practice paddock parking distancing.
- Do NOT enter the T&S trailer unless asked; everyone must wear a mask in the trailer.
- As you interact, if you meet someone who is wearing a mask, please also put your mask on while speaking with them.
Operational Guidelines and Information:
- Registration Check-in will be at the Lincoln Drivers’ Center (LDC) at the designated times; workers will have PPE available.
- Tech Inspection will be a self-inspection of the competitor’s vehicle, including a Registration Check-in component. More info below.
- Worker Check-in will be signaled by a raised flag at the LDC. Worker sheets will be posted online after final check-in has closed so competitors are able to verify that work positions did not change (due to cancellations/class changes). Course workers will check in at the LDC. Specialty workers will check in at their designated area with the Chief, i.e., Impound, Grid, Timing, etc.
- T&S Workers inside the trailer will always wear masks. Surfaces and tools may be sanitized between each work session
CV19 Related Materials and Supplies provided by SCCA for staff, field staff, and workers:
- Masks, Face Shields

SCCA Annual Waiver Information
- We are now accepting E-Waivers at National events.
- Go to the Event page, click on the link on the link for Mobile Speed Waiver (located under the Event information heading on the right side of the web page.
- You will also receive an email with a link to sign the E-Waiver for the weekend.
- This waiver will be used in lieu of signing a paper waiver (but does not take the place of any required track waivers).
- Waiver is good for Event Dates only, a new E-Waiver will have to be completed for each event.
- Armbands must still be worn to show that you have signed the waiver.
Tech Inspection Procedure:
The self-tech inspection procedure below will be used to minimize contact between drivers and event workers by expediting and decentralizing the process.
- A Chief Technical Inspector (CTI) will be appointed as per the National Solo Rules, Section 5.6. The role of the CTI will be to oversee the process and if needed conduct additional inspections of vehicles.
- A Self-Tech Inspection form will be available at the event site and online before the event. Go to the Event Page and click on the link for Tech Form (located under the Event information heading on the right side of the web page), download, and print. Bring the form with you to the event- ONE FOR EACH DRIVER.
- The driver will complete the form by conducting a self-tech of their vehicle when parked in the paddock, warranting that their car is compliant with the SCCA Solo Rules. If there are two or more drivers using the vehicle, a completed form is needed for each driver.
- While still in the paddock, the class designation and numbers will be placed on the vehicle. If the driver has them at this time, also place on the vehicle any SCCA required decals and appropriate contingency decals. SCCA required decals and some contingency decals are available at Tech Inspection.
- When the above is completed, the driver takes the vehicle AND their helmet to Tech Inspection, staying in the car while there.
- The driver gives their Self-Tech Inspection form to the CTI, or their designee, and shows them their helmet, again, staying in the car.
- The car will receive a quick review for numbers and class letters, plus any obvious mechanical issues.
- While remaining in the car, they will be asked if they need any SCCA or contingency decals AND if there are any changes to their event registration information (car, class, number, tires, etc.).
- If there are no changes, they will be checked in for the event at Tech and will not have to go to Registration Check-in. They can then return to the paddock
- If there are changes to their registration information, they will keep their tech form and exit the Tech area with their vehicle. They must go to the SCCA Timing Trailer at the designated time shown in the supps to complete any changes.
The check-in procedure below will be used to further simplify the process.
- Event supps will no longer be handed out when you check-in. They will be available by request. Supps will be posted online on the Event page as well as on-site in the following areas: Tech/Impound, Lincoln Driver’s Center & on the Timing Trailer.
- Schedules shown on the Event supps are the official schedule for the event.
- Work assignments will be posted on the Event page. A report showing the class listing will be created and it contains information about competitors’ registrations, including work assignments. Information will be available when you tech if you ask.
- If you have NO CHANGES to your registration, you can proceed through tech, turn in your tech form and you will be checked in for the event.
- If you HAVE CHANGES to your registration, you can proceed through tech, but you will need to KEEP your tech form and make your way to the SCCA Timing Trailer at the designated time for registration changes (see the supps for times). You will be checked-in for the event at that time.
- Once check-in is closed for the event, a finalized worker sheet will be posted online to the Event Page (8:15am). Please check there to verify that your work assignment has not changed due to class changes, cancellations, etc. Any work assignments that have changed will be highlighted in grey.
