2020 Rules

(This is an Entry Level Class)

Thank you for choosing to review the BusyBee Rumblebee Rules of the Medicine Hat Auto Racing Association (MHARA).  It is our mission to make racing fun and cost effective as we trend forward.

Currently there is no lap time rule but cars will be closely monitored.  If at any time track officials and / or club executive feels it is getting out of hand and non-competitive this rule may come into play.

MHARA executive or track officials may alter, change and implement penalties and methods to keep racing competitive.

History has continually repeated.  Faster cars go faster and faster and eventually there are no cars left in the class to compete against.  Steps will be taken to change the repetitive nature of stock car racing so a comfortable car count can be maintained.
