You are 50 m from a pedestrian crossing
when an elderly person starts to cross.
If you are travelling at 60km/h, will you stop in time? What if the road is wet?
if your vehicle travels 20 metres in braking to a stop from 50 km/h, at 100 km/h it will take approximately 80 metres to come to a stop on the same road surface (i.e. 4 x 20 metres).
