Question 5061

In relation to road safety, why is it better to drive at 30 km/h on an urban road instead of 50 km/h?

1. 1
   Because at 30 km/h aerodynamic drag is greater than at 50 km/h.
2. 2
   Because traffic flows more smoothly and there is no risk of an accident.
3. 3
   Because the lower the speed, the lower the probability that a pedestrian collision will be fatal.
