Rt.53 in Hingham,MA has a suicide lane. This is the appropriate name for a single track bidirectional lane for turning left. It is not used for passing. Great fun when people enter the lane too soon and facing cars must pass before each turns left. this leads to last minute entry into the lane and many stale-mates with stubborn cursiing drivers facing each other with no where to go as the prevailing traffic passes them on both sides.
