RESEARCH - Children May Not Detect Approaching Vehicles
As drivers, we tend to think that if we can see pedestrians, they can see us, especially during the day. This may not be the case with children if we are driving at speeds of more than 30 km/h. This is also the speed above which the chance of significant injury or death begins to be much higher for pedestrians who are struck by vehicles. We recognize this by posting a speed limit of 30 km/h in school and playground zones, but it could be a good reason to do the same on non-collector residential streets.
