Safety Swing Arm Children Slow Crossing Warning Blades

1975-1996
Those slow warning blades formerly said "IF-SAFE STOP THEN-GO". No longer offical as used of 1996 due to traffic confusion but still existed on few ice cream trucks or Childcare buses in few parts of New Jersey and New York and Maryland until 2018.

1996-present
In 1996 due to traffic confusion, the slow warning blades have been permanently recolored yellow and permanently reworded as "CHILDREN SLOW CROSSING". As of When the original Manufacturer of these Children Slow Crossing Warning Blades which was Specialty Manufacturing Company (SMC) introduced the new Defender Series Electric Stop Arms in 2017 and not have enough room for the Children Slow Crossing Warning blades on the new Defender series electric bases so the SMC gave their supplies of making the Children Slow Crossing warning blades to Canada's Stop arm manufacturing company called BMR so Now these Children Slow Crossing Warning Blades are now on BMR stop arm bases not Specialty Stop arm Bases anymore.
