The Town of Newmarket's crossing guards ensure children in the community are escorted safely across roadways. Drivers are reminded to take caution in school zones and to look and listen for the crossing guards' stop sign and whistles.
- First whistle: the guard proceeds to the centre of the roadway to stop traffic
- Second whistle: the guard sounds this when traffic has completely stopped, to advise children that it is now safe to cross the roadway
- Third whistle: the guard sounds this when the children and the guard have safely crossed the road, indicating to the driver(s) that it is now safe to proceed
