The City is installing a number of new button activated Pedestrian Crossovers to improve pedestrian safety. At these locations drivers are required by law to stop until pedestrians have fully crossed the road before proceeding. This is different than at typical intersections where drivers may proceed once a pedestrian has crossed halfway across the road.
Pedestrian Crossovers can have a few different layouts but are designed by these key elements: 'Stop for Pedestrian' signage, a triangular yield line painted on the road, and optional rapid flashing yellow beacons.
To get an idea of how these Crossovers work please watch this video provided by the City of Hamilton.

Example of a new Crossover (PXO) referenced from Ontario Ministry of Transportation website
Pedestrians need to press the button to activate the yellow flashing beacons and ensure approaching vehicles are coming to a stop before stepping out on the roadway. Make sure drivers see you before you cross. If the driver is stopped, make eye contact before you step into the road.
Drivers and cyclists must stop and yield the whole roadway at pedestrian crossovers and school crossings where there is a crossing guard - it's the law! Watch for children. Always look for pedestrians, especially when turning.
The penalty for not yielding the whole roadway to pedestrians at pedestrian crossovers and school crossings is a fine in the range of $150 - $500 and drivers may also face three demerit points upon conviction. Fines are doubled in community Safety Zones.
It is up to both drivers and pedestrians to keep everyone safe on Ontario roads. Do your part and be a kind, courteous driver.
