# Speed vs Safety

## How much time does it take?

Yes, driving slower will take more time, but just how much time does it take to cross a 200 metre school zone?

 At 30km/h it will take 24s At 40km/h it will take 18s At 50km/h it will take 15s At 60km/h it will take 12s

## Stopping Distances

The faster your vehicle is travelling, the longer it will take to come to a complete stop when the brakes are applied.

At 30km/h, 5 metres
At 40km/h, 9 metres
At 50km/h, 14 metres
At 60km/h, 20 metres

These distances do not take into account the time required to perceive and then respond to a given situation. These approximate distances describe the amount of space needed to come to a complete stop after engaging the brakes.

## Impact Force

What if you can't stop in time? What if you haven't paid enough attention, and your car has hit someone?

The exact force of a collision will vary depending on the weight of the vehicle, but a collision at a higher speed will deliver exponentially more force than a collision at a lower speed.

Even at 30km/h, a collision can cause severe injury to the head, torso, and limbs, but:

A collision at 40km/h would deliver 70%
more force

A collision at 50km/h would deliver 180%
more force

A collision at 60km/h would deliver 300%
more force
