2014-15 Midwest Slot Car Series Rulebook

 

General Rules

 

Common sense

If it is not listed in the rules, it is not legal!

MSCS Officials have the final say on all rules.

 

Entry fee:

No membership fee. $10 entry fee per class.

 

Race Format

Standard Races will have 2 minute heats with a 2 minute lane change.

Mid-season "Doubler" will have 3 minute heats with a 2 minute lane change.

 

Marshaling

All drivers are expected to marshal the race(s) preceding their own races. Failure to fulfill marshaling responsibilities will result in lap penalties and/or disqualification.

All cars will be impounded after all races to insure fair and proper marshaling responsibilities.

 

Lane Change

Following each lane change, all cars must be returned to the track at the position where they were taken off.

Lane change cards are required.

Cars may be moved backwards to allow easier restarting.If cars are put on forward of the stopping position it will result in a two (2) lap penalty. A second infraction will result in disqualification.

It is the drivers responsibility to know where his car has stopped.

 

Protest

A competitor may protest another racer's equipment by informing the race director before the start of the last heat.

A protest fee of $10 and a written protest form is required during the protest of a competitor's car. The race director will hold this protest form and fee until completion of the final heat.

Forms will be provided at all races.

 

Points

Points will be awarded based on finishing position (50, 48, 46, 44, 42, 40, etc.)

The top three in the championship will be paid at the end of the season.
