News & Updates


Last year during the season on track situations caused additional rules to be established during the ISR rules session. These affect restarts, restart assistance, crews ability to work on sled, and driver repair of sled. These rules were generated from an incident at TLR event, not part of the USSA Prostar Series.

Restart assistance on the track:
With the Race Director’s permission, only one (1) crewmember (per snowmobile) will be allowed on the track in the event the competitor cannot start his/her snowmobile alone. No mechanical work can be performed by the crew member. He may assist the driver in starting the sled, by pulling the recoil device/rope, controlling throttle, applying choke/enrichner, or alternate fuel delivery squirt bottle, removing the hood, securing hood, and tether switch, handing safety and personal equipment to driver.

Fluid replenishment and inspection under red flag conditions:
(Oval Sprint) Under Red Flag conditions up to 3 pit crew members per sled are allowed on track to add slide lube and perform engine and radiator cooling functions to the sled. Upon be summoned to restart, all crew members shall leave the track surface except the designated crew member who assists in the engine starting procedure with the driver.

Driver repair of sled under red flag conditions:
Under the red or yellow flag, drivers only may work on their snowmobiles on the course proper and must use only parts and tools carried on the course by themselves, or contained on the vehicle at the beginning of the event/race. Race director has authority to indicate to driver which items are acceptable to carry on ones person, or must be compartmentalized in the vehicle. Note: Under Red or yellow Flag only. No work can be done during green flag racing.

Special Note: Drivers tools and repair parts must be compartmentalized in the sled chassis. Drivers are not allowed to carry specific tool items on their body, as this is considered a safety hazard during crash situations.

Ski Loop failure and disqualification rules updates were generated from a incident at a USSA TLR event but affects all classes except Outlaw.

Ski Loop Failure:
Ski loop failure during an event is a automatic mechanical black flag. The disqualification for the race will take place whether the driver is notified while on the track or not. This includes notification by Black Flag, notification by radio transmission, or verbal notification after the event either by the race director, flagman, or technical inspector.

Ski loop failure in a heat, round or final event results in a DQ (disqualification) from that particular event. In the case of rounds, drivers may repair and return to the next round of competition. In the case of race events that pay points or money for positions in rounds, drivers will be given the scoring position earned by the normal scoring procedure order of finish. In the case of race events that pay money for a all positions in a final, the driver will be given position earned in normal scoring procedure order of finish.

In the case of events with heats, DQ'd drivers will be allowed to repair and enter the final, only if positions are open on the line after normal scoring procedures for all other competitors is completed. These rules apply to all sleds in OVAL SPRINT COMPETITION. These rules do not apply to Outlaw 600 class.

New Safety Equipment requirements:
All oval classes except 120 will be required to wear operational race-ceivers during competition. This will allow the race director or his designate to communicate restart order, possible pending mechanical failures to drivers, and relay information on driver conduct during a event. This will be mandatory at all USSA events. Please source your race-ceiver locally and have with you at the track when competing. Since they are plentiful and used in most car racing organizations, obtaining one should be a simple task. USSA will keep several on hand in case yours fails during a event. Rental of the unit will be done by leaving your driver's license or a valid charge card with USSA, Rental will be $50.00 per event, if needed. Race-ceivers are normally sold in the $100.00 to $160.00 range depending on ear piece, so it is your best interest to obtain one before the season and have it ready with your helmet and Safe-Jac. USSA will stock spare batteries for sale for the units at $2.00 each. Please prepare ahead of time so you can comply with this new rule.
