Supplemental Regulations for 2004

General Event Procedures

1. Events will be conducted in accordance with the current SCCA National Solo II rules, except where modified or superseded by these Supplemental Regulations.
2. Failure to Work: All entrants will share the workload. An entrant failing to complete his/her work assignment will be scored as "DNW" (Did Not Work). The published results will reflect a DNW finishing position for the entrant and no points will be awarded for the event.  Any entrant wishing to work a group other than his/her assigned group must make arrangements with the event chairman.
   Any entrant who receives more than one DNW finishing position in a calendar year (including Championship Series, Slush Series, and any special events during that calendar year) will forfeit all points and/or trophies earned during that year, and will be disqualified indefinitely from entering any subsequent SFR Solo II events.
   Disqualification may be appealed with a written explanation presented in person at a regularly scheduled meeting of the SFR Solo II Steering Committee. (03/03)
3. The maximum number of runs allowed is three per entrant.  When circumstances warrant, the event chair(s) may reduce the number of runs entrants will receive at an event. 
4. In order to receive class points towards series awards, all entrants must run in their assigned run group .  To aid in the preparation of accurate results, it is the responsibility of entrants not running in their assigned run group to include " WRG" (Wrong Run Group) on the top margin of their card.  During an event, when timing and scoring notes that an entrant is running in the wrong run group, timing and scoring may add "WRG" to the top margin of that entrant's entry card.  WRG entrants will be scored in the results as "WRG" and will receive no points for the event.
5. At the discretion of the event chair, a second set of runs may be sold at normal event price.  These runs, defined as instructional runs must be taken in a separate and later run group than competition runs. A separate work assignment in the appropriate work group is required for instructional runs. Failure to work for instructional runs will result in ALL runs (both competition and instructional) being scored as DNW for that event ( see "Failure to Work" above).
6. For the date of the event, the speed limit for any SFR Solo II site is 10 mph, unless otherwise posted. This includes grid, pre grid, and all pit areas. Speeding, "squirreling", scrubbing tires, or testing suspension at the event site are considered unsafe practices. Violators shall be subject to disqualification from the event as outlined in "Safety Disqualification"  below .
7. Access to the course inner area and outer boundaries during runs is limited to workers for that group, safety stewards, event chairpersons, and photographers approved by the event chairperson. Spectators and other photographers must stay within the spectator boundaries at the start/finish lines and trailer area. A spectator is defined as any participant not directly involved with that run group. This includes workers who are not working and drivers who are not driving. Photographers must have a "spotter" in their presence at all times while beyond the spectator boundaries.
8. The event chair(s) may combine run groups and/or reduce the number of runs during the event, provided there is a 30 minute gap between the announcement and implementation of the change.
9. Bicycles, skateboards, roller skates, in-line skates, scooters, go-peds, etc. are prohibited in the grid/course area. All pets must be on a leash at all times.
10. Safety Disqualification: Safety Stewards observing violations and/or unsafe actions which are punishable by disqualification must notify the Event Safety Steward. The Event Safety Steward must notify and obtain the approval of the Event Chair prior to notifying the entrant that he/she has been disqualified. Once approval has been obtained, the Event Safety Steward, Event Chair, or designate may notify the entrant of the disqualification. Stewards observing actions which are considered unsafe, but not punishable, should notify the affected entrant directly. Failure to comply with the Event Safety Steward may be punishable by disqualification from the event by the above procedure.
11. Sound Policy: The sound limit is 95 dbA at 100 feet. If an entrant records sound reading(s) during an event in excess of the limit, the entrant is charged with a "sound violation". Second and subsequent "sound violations" during the year ("year" is intended to include regular schedule, Slush schedule, and any special events during a calendar year) will result in disqualification and loss of series points for the event(s) violated. When a weekend includes events on more than one day, sound violations recorded on more than one day will be counted as a single violation.  Disqualification may be appealed with a written explanation presented in person at a regularly scheduled meeting of the SFR Solo II Steering Committee.
12. An event's advertising shall be a part of that event's supplementary regulations.
13. Protest fee for SFR events is $25.00.
14. Protests:
    1. Protest(s) may be filed by a competitor against only another car or competitor running in his/her class. Such protest(s) will be accepted by the Protest Chief (PC) or, in the absence of the PC, the event chair only on the day of the event. Conduct-of-event protest(s) (timing errors, cone counts, re-run issues, etc.) will not be accepted by the PC. Issues of this type should be addressed to the event chair(s) for resolution.
    2. Late protest(s) may be accepted by the PC based only on improper model classification. Such late protest(s) may be filed no later than two weeks after the event.
15. Passengers: Passengers are allowed at any time within the limits set in the SCCA National Solo II Rules Section 1.4.  Any entrant may ride as a passenger at any time without penalty.
16. Filling out entry/score cards: Cards must be filled out completely, including car number and class designators (base, Ladies, Street Tire, or Novice class). If a woman decides to run in the Ladies class, she must put "L" with the base class, e.g., "CSP-L". An "L" after the number is insufficient information. An entrant in the Novice class must put "N" with the base class, e.g., "CSP-N".  For instructional runs write "FUN RUN" in the top margin of the card.  When running in the wrong run group, write "WRG" in the top margin of the card
17. Car numbers and classes: Each competing car must have numbers and complete class designation clearly shown on both sides of the car.  For multiple entrant cars,only the number and class of the entrant driving may be seen during each respective run.  (Paper numbers handed out at registration for an event may be used without class designation to satisfy the requirements of this section).

Course & DNF Procedures

18. Course design: If there is no practice lap, the entry to the course will have a 90 degree turn prior to the point where the competing car starts the clocks.
19. Minimum course width shall be as stated in the SCCA National Solo II Rules (15 feet, in the 2002 rules).  Minimum inside turn radius is 25 feet.  For any course turn, a minimum width (15 foot) path, with a minimum inside turn radius of 25 feet, must fit within the course penalty markers (pylons). However, the required first 90 degree turn at the start is not restricted by these limits.
20. Both sides of the course will be lined with gypsum or an appropriate substance when allowed by the weather and property owners.  Slaloms may be lined or unlined.
21. Pylons exceeding 18 inches in height may not be used as slalom and/or apex cones.
22. Pylon penalties shall be charged to an entrant only if a pylon is upset or if the base is displaced and comes to rest entirely outside its chalked outline on the pavement during a timed lap. No penalties will be charged on practice or warm-up laps.
23. The entry and exit lanes are part of the course for purposes of scoring and determining DNF (Did Not Finish).
24. At events with a practice lap, after the green flag is given, signifying the clock has started, all pylons which are upset or displaced are chargeable. This includes all pylons marking the exit lane to the pit area, but not those marking the course entry prior to the green flag .
25. When an entrant driving the course sees a red flag being waved by a worker, he/she must come to an immediate stop.  After stopping, with or without any explanation from the worker(s), the entrant should quickly proceed to safely complete the course at reduced speed (not to exceed 25 MPH) in order to clear the course for the following entrants.  When an entrant is " red flagged" he/she is entitled to a re-run.  Any course deviations and/or pylon penalties incurred by the entrant prior to the red flag stop are eliminated and are not counted against the re-run time.
26. When an entrant driving the course encounters an upset or displaced cone, he/she may stop and, after gaining acknowledgment from a course worker of the errant cone, quickly proceed to safely complete the course at reduced speed (not to exceed 25 MPH) in order to clear the course for the following entrants.  If acknowledged by a course worker the entrant will be granted a re-run and any course deviations and/or pylon penalties incurred by the entrant prior to the red flag stop are eliminated and are not counted against the re-run time.  However, an entrant will not be given a re-run for an errant cone he/she previously upset in the same run.
27. If there is no practice lap, all pylons are subject to penalty.
28. Once having entered the course, the entrant must remain in the driver's seat until that run is complete. If the entrant leaves the driver's seat during a practice or timed lap, that run shall be scored as a DNF.  An entrant whose car is repaired, serviced or pushed by any person during a practice or timed lap will incur a DNF for that run. 
29. No time will be included in the results for a run in which a DNF has been charged.

Run Group Formats

29. There will be a "mid-day" walkthrough at all Championship Series and Slush Series events.  Four groups run before this walkthrough whether six or eight run groups are scheduled for an event.  The grid for the fifth group will not close before 1:00 p.m.  Registration will close at 12:00 Noon and tech inspection will close at 1:00 PM. Certain sites may require use of different ending times than those above; an event chair may change these as long as the changes are published a reasonable amount of time before the event.
30. Inverted Grid: In the first run group, the grid will be managed in inverted order.  This means the first car on grid parks at the "back" of the "last" line and each additional car parks ahead of the most recent car to park on grid.  The last car to park on grid is the first car to take a run, and the first car on the grid will  be the last car to take its first run.  Multiple-entrant cars return to the multiple-entrant line(s) after their first run (see below). 
31. In the second and succeeding groups, the grid will have one or more designated multiple -entrant lines. The grid marshal for each run group shall have the first entrants of the multiple-entrant cars compete before any of the single-entrant cars. When the first  entrants of the multiple-entrant cars have made their first runs, the grid marshal shall start alternating the single-entrant cars and remaining multiple -entrant cars.
32. Multi-Entrant Run Sequence: All entrants will take their Nth run before any entrant takes his/her Nth+1 run. All cars shall return to their same line between runs, unless the grid marshal directs them to do otherwise.
33. There shall be a maximum of four entrants per car per run group.
34. In cars with multiple entrants , the number distinction must be clearly visible. Scoring errors resulting from multiple entrants/numbers’ errors are the fault of the entrants and must be protested to the event chairman by the established procedures.

Grid Procedures

35. Grid for all run groups will close 15 minutes after the announcement that the grid is open.  Grid opening time for each run group will be at the option of the event chair(s).
36. When an entrant arrives on grid after it is closed, that entrant's last run will not be scored, but will be listed as a "LOG " (Late on Grid.)
37. No more than four cars will be allowed at any one time in the staging area.
38. In any run group, when the staging area and grid are empty, the event chair(s) may declare that group as having made its runs even if everyone has not taken their runs. The event chair(s) or grid marshal shall assume those cars not taking all their runs are doing so voluntarily.
39. Any repairs which do not delay the event and can be made on the grid will be permitted. Such repairs are subject to a safety tech inspection.

At the option of the grid worker(s), a car being repaired may be moved out of the grid line to allow other cars to proceed to the start line.  If the repairs are not completed in time for the car to be presented for running in the proper run-number sequence (for example, the car is not ready to make run #2 after all other cars have completed their run #2; see " Multi-Entrant Run Sequence" above ) the run is forfeited and scored as an "MDNR" (Mechanical - Did Not Run).  The grid worker(s) must advise timing and scoring of the MDNR.
