CCR Rule 25.4.1 - Passing General
The responsibility for the decision to pass another car, and to do it safely, rests with the
overtaking driver. The overtaken driver should be aware that he/she is being passed
and must not impede the pass by blocking. A driver who does not watch his/her mirrors
or who appears to be blocking another car seeking a pass may be black-flagged and/or
penalized. The act of passing is initiated when the trailing car’s (Car A) front bumper
overlaps with the lead car’s (Car B) rear bumper. The act of passing is complete when
Car A’s rear bumper is ahead of Car B’s front bumper. “NO PASSING” means a pass
cannot even be initiated. Any overlap in a NO PASSING area is considered illegal.
