EVENT FORMAT

Qualifying* – Where applicable, drivers can make two qualifying passes (one in each lane), of which the best one will be taken to determine seeding. Driver’s that get DNF’s or DQ’s will be moved to the bottom of the bracket. If a driver breaks during practice he will receive a DQ qualifying time and be seeded at the bottom of the bracket for eliminations, or if applicable, maybe allowed to move to bottom of qualifying session to make a legal pass.

Elimination – After qualifying (if applicable) is complete, drivers will race in heads up elimination bracket racing until a winner is determined. Higher qualifier gets lane choice. If a winning driver cannot make the next round due to breakage then the previous “loser” will be brought back to take their spot. If both trucks DNF the race will be re-run until there is a winner. If a driver cannot restart the race after a dual DQ it will be awarded to the truck that is still running.

Did Not Finish (DNF) – A driver will receive a DNF for needing to marshal their vehicle. Vehicle touching is prohibited. You must drive smart as well as fast. You will also receive a DNF for leaving your lane and hitting another vehicle.  Other DNFs may apply if a Trigger King RC official makes such call.

Freestyle – Trucks will have open freestyle on the track, one at a time. Freestyle will be done by three judges, each giving a score based on a scale of 0 to 10, with 10 being the best.

Sport Mod Freestyle –  60 seconds will be allowed.  Zero rollovers are allowed per freestyle run.  If a truck rolls, that will end their run.  No props are allowed in freestyle and vehicles must stay inside boundaries of freestyle course during their run.

Pro Mod Freestyle – 90 seconds will be allowed.  One rollover is allowed per freestyle run.  If truck rolls a second time, that will end their run.  No props are allowed in freestyle and vehicles must stay inside boundaries of freestyle course during their run.
