Leaders should be very vocal when preparing to pass any racer. “PASSING on your LEFT!,” “PASSING on your RIGHT!” should be called out. It is the responsibility of the lapped races to inform the leader when and where it is safe to pass. It is the responsibility of the challenging racer to overtake safely. If the lead racer uses force that puts the lapped racer in harms way during passing this will be considered unsportsmanlike and can be grounds for a penalty. Unsportsmanlike behavior by any racer will not be tolerated and should be reported immediately.
