Addendum to L.O.S.C. rulebook (Nov. 21, 2014)

Multi driver teams will be allowed in 2015 and beyond.

A principal driver is to be named when registering. The others driver(s) need not necessarily be named at this time. It is also possible to switch to a multi driver team at any time under certain circumstances at the discretion of N.S.C.A. directors.

Points will go to the car number when you are registered as a multi driver team.

Just because you register as a multi drive team does not mean more than one driver is necessarily required to compete. If the team’s principal team driver is able to attend the races they need not use another driver at all. If one of these multi diver teams wins the Championship it will be determined if we have a single Champion, Co-Champions or a Team Championship.

All divers must be approved by N.S.C.A. directors.

Rookie points go to the driver rather the car in regards to multi-driver teams unless all drivers on the team are rookies.

If you are not registered as a multi driver team and want to put someone else in the car for a race, the points will go to that driver as it was in the past. In this case you will not have to pay the extra membership fee.

NSCA LICENSING FEES
Single Driver Team Membership $300.00 (Points go to the driver)
Multi Driver Team Membership $400.00 (For teams using 2 or more drivers – points go to car#)
Race Entry Fee $50.00 (Non-members $100.)
