I've raced a few years of Jeepspeed. I thought the blue light was to designate a speed difference. Some clarification in the rule books wouldn't hurt. Something else to consider, sometimes there isn't a place to move over. With limited suspension travel, solid axles, and 33" tires, I have to be selective on where I move over. I'm not going to chance hitting a big rock or bush off course just so someone can get by.
