If you’re riding along the road and see your fellow motorcycle riders tapping the top of their helmets as they pass you in the opposite direction, slow down and be cautious. In most of the U.S., this is a warning that the police are nearby.
This of course could be any number of scenarios where the police would typically be present. An accident, a road closure, an officer waiting to catch speeding motorists, or an officer who’s already pulled over a speeding motorist. In any case, be sure to slow down and prepare for anything when you see this warning from other riders.
