First, I cannot stress enough the benefit of reflectorized vests, belts, straps, of flashing clip-on lights, or of any device that allows automobile drivers to see where you are (and ideally avoid you). Some clubs have ignored this advice, to their own peril. Also, please, please, please stress to your members it is their responsibility to look out for motor vehicles; the average driver on their way home from work, or on their way to soccer practice are focusing on everything else but the thinclad crossing the intersection.

Second, a cell phone with photographic capabilities will help in the event of a vehicular encounter or a meeting of the (un)mind(ful). Calling a member of the local constabulary rather than dealing with an angry driver is a good bet; you can give a description of the harrassing driver's vehicle and perhaps even a license plate number.

Third, carry some form of identification; something that has your full name, a valid address or telephone number, & what many law enforcement agencies call ICE – In Case of Emergency. Let someone know your route and estimated time of return, also.
