when a police man pulls you over because you didn't come to a "complete stop" at a stop sign. basically if your wheels don't stop moving before you proceed a police man can and will pull you over.
driver: what seems to be the problem officer?
Police guy: you ran a stop sign, you didn't come to a complete stop.
driver: a cowboy stop? are you serious?? c'mon man i was barely moving and there were no other cars.
when driving country roads late at night and approaching a four way intersection, instead of stopping, you turn your headlights off to see if headlights are coming from the other directions: no lights means green lights.
