Driving around any Northern BC community, motorists inevitably encounter School Zone signs. As you slow down, you may have wondered, “How much difference does it make to drive at 30 km/h, rather than 50 km/h?”
A big difference, actually. A vehicle travelling 50 km/h has more than double the kinetic energy of one going 30 km/h. And if a pedestrian were to be hit by a car, they have a 10 per cent risk of dying if hit at 30 km/h; but an 80 per cent risk of dying when the speed is just twenty kilometres per hour faster.
