Here is a little tidbit out of the rulebook, I capitlized, in red, a key word:
1.B CLASSIFICATION:
It is the responsibility of the owner and/or driver to enter a vehicle in its proper class. However, a vehicle is subject to class verification by the Contest Board at any time. THE SCTA/BNI CONTEST BOARD WILL NOT RECLASSIFY A VEHICLE ENTERED IN THE WRONG CLASS. ALL VEHICLES WILL RUN ONLY IN THE LOWEST PRIMARY CLASS/ CATEGORY FOR WHICH THEY ARE LEGAL. IF A VEHICLE IS NOT LEGAL FOR A SPECIFIC CLASS IT MAY NOT NECESSARILY BE LEGAL FOR ANOTHER CLASS. THE VEHICLE SHALL MEET ALL CLASS REQUIREMENTS TO BE LEGAL FOR COMPETITION. ONCE A VEHICLE HAS LEFT THE STARTING LINE, THE ENTRY NAME AND CLASSIFICATION INFORMATION WILL NOT BE CHANGED.
If an appropriate class exists, a vehicle shall run in that class. Any vehicle which is not legal for any class, but meets all technical regulations, MAY be allowed to for time only. No trophies will be awarded for "time only” entries. Any questions regarding the proper classification of a vehicle shall be directed to the class chairperson as listed in Section 17.
With all the recent talk of too many entries, lack of housing, etc. the suggestion was made here to drop time only entries. If this happens it may preclude the running of NASCAR types.
