“…..the driver of any vehicle
or street car approaching the school crossing guard
shall stop before reaching the crossing and shall
remain stopped until all persons, including the
school crossing guard, have cleared the roadway
and it is safe to proceed.”
“Where a school-crossing guard displays a red and white stop sign, you must stop before reaching the crossing and remain stopped until all people, including the school crossing guard, have cleared the entire roadway and it is safe to proceed. If you have any doubts about when it is safe to drive forward, wait until all the children and the guard have cleared the crossing. Drivers who don't follow the stopping requirements may receive a substantial fine and get three demerit points.”
