School buses and stop arms?

What is a stop arm?
A stop arm is a school bus warning signal. We're all familiar with the yellow school bus with its signal lights and a red stop arm that swings out to warn when children are crossing. It seems matter-of-fact that you would see this on a school bus.

The controversy
Some communities in Saskatchewan have banned the use of the signals. They feel it gives a false sense of security. North Battleford is disrupting the ban. Regina and Saskatoon are not allowing signals to be used. In the city school buses are using their ordinary four-way flashers when they stop to let children on and off. Yet in the town of Battleford the school bus drivers use their stop arms and the flashing safety signals.

There is a referendum set for October 28 to determine whether to allow the signals again. It would make more sense if the rules were consistent province-wide.

Insurance answer
Certainly this issue needs to be resolved. For any driver to hit a pedestrian would be a terrible thing. For that pedestrian to be a child would be horrendous. Studies need to be done to determine what is the safest recourse and a province-wide regulation should be in force.
