The school buses in my town have a wire loop mounted on the bumper which swings out when the bus is unloading children. The loop forces children to go far enough in front of the bus that they are in the drivers field of vision, and not hidden by the hood (or bonnet if your from the UK). Written permission to use these examples can be obtained by writing a short request with your name and company affiliation. Generally, I am willing to extended permission free of charge, if you will include a reference to mistakeproofing.com in your document or presentation.
