From what I recall and have on reference here at the shop in past WKA Rule Books:
310.1 Rear View Mirrors
Are allowed provided they are mounted securely and safely to the kart and do not present a hazard to other vehicles. They are not to be used as an aggressive device to facilitate blocking.
*I’ll do some additional searching Ace, so don’t hold me to it as the RR Rules Sheets I have here (for general reference) are from 2012. I can check my “current” 2014 WKA copy when I get home.
