Traditional rules

*Whataburger Rule
In lieu of a cruise for Limited Street, the Whataburger rule will be invoked in the event the streetability of a contestants car is questioned. The protestor will hand the protestee $20, along with a requested menu item from Whataburger. The protester must drive, in their race vehicle, to the Whataburger off 146, retrieve the requested menu item, and return to the race track. If the protestees vehicle is unable to complete the trip under its own power, that contestant is disqualified from the event, and must return the $20 to the protestor. If the trip is successfully completed, the protestee will keep the change.
