Support car A should slow down to let cyclist B pass on the passenger side. Once cyclist B is safely past support car A (or, if the overtaking manoeuvre takes place at night, within the headlight beams of support car A), support car A should let support car B pass on the driver side. As support car B accelerates to pass support car A, support car A and cyclist A should slow down together so that support car B can safely pull back over to the left behind cyclist B. Cyclist A must then allow support car B to move at least 100 meters ahead or risk being penalized for illegal drafting. This process of overtaking should be done as quickly as possible and only when the traffic situation allows for such a manoeuvre to take place safely.
