3.1.4 Drivers possessing a USMTS National Tour regional license are eligible to earn points for events held in the region for which they possess a license. Drivers possessing a USMTS Southern Series license are eligible to earn points in all USMTS Southern Series events. All drivers who qualify for The Hunt (see Rule 3.8) are eligible to earn points in The Hunt with the purchase of a Hunt license or any other (2) licenses (National Tour or Southern Series). Drivers who are not qualified for The Hunt may purchase a license for The Hunt and shall be eligible for all of the benefits of a licensed driver except points and points funds.

3.1.5 Drivers must be licensed prior to the start of an event in order to earn points for that event. Points will not be awarded retroactively.

3.2 Points:

3.2.1 In addition to possessing a valid USMTS license, drivers must also meet other eligibility requirements in order to earn points in an event, including, but not limited to, utilizing American Racer KK704 tires on all four wheels and displaying required USMTS and sponsor decals.

3.2.2 Points will be awarded to each eligible driver in the “A” Main as follows: 1st - 100 points, 2nd - 95 points, 3rd - 91 points, 4th - 87 points, 5th - 84 points, 6th - 81 points, 7th - 78 points, 8th - 76 points, 9th - 74 points, 10th - 72 points, 11th - 70 points, 12th - 68 points, 13th - 66 points, 14th - 64 points, 15th - 62 points, 16th - 60 points, 17th - 58 points, 18th - 56 points, 19th - 55 points, 20th - 54 points, 21st - 53 points, 22nd - 52 points, 23rd - 51 points.

3.2.3 Hard Charger Bonus: One (1) bonus point is awarded to each driver in the “A” Main for each racecar passed from the original starting spot. For instance, if a driver starts 18th and finishes 11th, that driver will earn an additional seven (7) points.

3.2.4 Lap Leader Bonus: Each driver that leads at least one (1) lap in the “A” Main will earn one (1) bonus point. The driver that leads the most laps in the “A” Main will earn two (2) bonus points (tie goes to the highest-finishing driver).

3.3 Qualifying Procedures:

3.3.1 The following qualifying procedures are typical, but may be altered on a per-event basis when USMTS officials deem necessary due to car count, track or weather conditions, attrition, etc.

3.3.2 Drivers must draw for starting positions in heat races. Cut-off for draw is typically 15 minutes prior to start of hot laps. Drivers failing to draw before cut-off time shall be lined up at the rear of the earliest heat race with the smallest starting field.

3.3.3 Drivers failing to start their scheduled heat race shall be scored in last place for that heat race. Drivers shall not be allowed to start at the rear of another heat race if they fail to start their scheduled heat race.

3.3.4 Heat races will award 59 points to the winner, then descending by 4 points for each finishing position thereafter (59-55-51-47-43-39, etc.). Each driver will earn an additional 1.5 points for each racecar passed in the heat race, based on actual starting position versus actual finishing position. The sum of these points shall be the driver’s Passing Points. Typically (depending on car count), the top-12 drivers in Passing Points qualify for the first 12 starting positions in the “A” Main. Of those, the top-8 drivers in Passing Points will redraw for starting positions 1 through 8, with the remaining four drivers starting “heads up” by Passing Points in positions 9 through 12. Officials may elect to stage a “dash” race among the top 8 qualifiers to determine the starting line-up (this is not typical).

3.3.5 One or more “B” Mains will be staged with non-qualified drivers starting “heads up” by Passing Points. The top-12 “B” Main finishers (typical) shall start the “A” Main in positions 13 through 24, “heads up” by “B” Main finish. If a “B” Main driver qualifies for the “A” Main but is unable to start the “A” Main, the next highest finisher behind that driver in the same “B” Main shall transfer.

3.3.6 When the total number of entries for an event is 40 or less, 24 drivers shall start the “A” Main. When the total number of entries for an event is 41 or more, 26 drivers shall start the “A” Main.

3.3.7 There shall be no provisional starting spots awarded in any USMTS “A” Main.

3.4 Top Dog Bonus:

3.4.1 In each USMTS National Tour region and The Hunt, drivers ranked among the top-10 in points will be guaranteed a minimum of $400 in earnings at each event where that driver is among the top-10 in points for that region or The Hunt. USMTS Southern Series drivers will earn a minimum of $300 for those among the top-10 in points and $200 for drivers ranked 11th through 15th in points.

3.4.2 Drivers must have perfect attendance in the USMTS region, USMTS Southern Series or The Hunt where the event is held. Once a driver misses a single race in a particular region, USMTS Southern Series or The Hunt, that driver is no longer eligible for the Top Dog Bonus in that region, USMTS Southern Series or The Hunt.

3.4.3 The Top Dog Bonus will take effect beginning with the third race in each USMTS National Tour region or USMTS Southern Series. The Top Dog Bonus will take effect beginning with the first race in The Hunt.

3.5 Points Funds:

3.5.1 Points funds shall be paid out to no fewer than the top-10 finishers in USMTS National Tour and USMTS Southern Series final points. USMTS National Tour regional points funds are based on ten (10) races or more and shall be prorated if fewer races are completed in that region.

3.5.2 Actual points funds awarded in each USMTS National Tour region and the USMTS Southern Series shall be the percentage of actual events competed in by that driver multiplied by the amount scheduled to be paid for that position in the points standings. Points funds for The Hunt shall not be reduced because of driver attendance.

3.5.3 In the event of a tie for first-place in the final points of the USMTS National Tour, the winner shall be the driver with the most wins during The Hunt. In the event of a tie for first-place in the final points of the USMTS Southern Series, the winner shall be the driver with the most wins overall. Should a tie still exist for either series, the next determining factors shall be top-5 finishes and top-10 finishes, events started, respectively.

3.6 The Hunt shall be comprised of the final 10 to 18 USMTS National Tour events of the season (depending upon final schedule, rain-outs and/or other unforeseen circumstances) and shall determine the USMTS National Champion, the final USMTS National Tour points standings and subsequent points funds to be distributed. The USMTS points system (see Rule 3.2.2) shall be used at all USMTS National Tour regional events and the USMTS Southern Series, with the top-10 in the final points standings in each region and USMTS Southern Series earning 10 base points for first place, 9 base points for second place and so forth, descending to 1 base point for 10th place. Each driver who competed at all events within a USMTS National Tour region or the USMTS Southern Series prior to the first event of The Hunt also earns 5 base points, regardless of finishing position. The cumulative base points earned for all four regions and the USMTS Southern Series shall serve as the total points that each driver will start The Hunt with. The USMTS points system will be used at the remaining events in The Hunt to determine the USMTS National Champion and subsequent final points standings.

3.7 The final points standings in the USMTS Southern Series shall be determined by each driver’s best twenty (20) points-earning performances in all USMTS Southern Series events. In the event that fewer than 20 events are staged, all events will be used in calculating a driver’s total points.

3.8.8 Rookie points in the USMTS Southern Series shall be awarded to each rookie driver based on his/her best twenty (20) points-earning performances in all USMTS Southern Series events. In the event that fewer than 20 events are staged, all events will be used in calculating rookie points.
