Russian motorists: Flashing your headlights at an oncoming car warns of the traffic police ambush you’ve successfully passed by.
Since Russia’s prehistoric times there’s been violent confrontation between the motorists and the traffic police: the latter in search for easy money lie in wait to snatch overspeed fines. Westerners can hardly understand why the hell policemen would do so! This all is a big quest of easy profit. Luckless drivers get caught by crafty police officers and would only want to get rid of the paper torture by all means…
Greasing police palms became an ordinary road procedure, like toll or pay for gasoline. Thus motorists came to realize one day they could save if they had warned one another against unplanned pays. Now Russia’s most widely-practiced motorist’s headlight communication is a short double headlight flash saying to an oncoming car driver: “hey, buddy, throttle back or pay! The stripy-baton dudes are expecting you at that turn!”
Flashing is bad, flashing is illegal, policemen fight headlight flashing signals as hard as they can… Nevertheless motorists keep warning fellow-drivers as a kind of social response to infinite lawlessness and corrupt officers’ squeeze.
