Speed reduces the amount of available time needed to avoid a crash or to stop
the vehicle.
Speed extends the distance a vehicle travels while the driver reacts to a
dangerous situation.
Speed reduces the ability of the driver to steer safely around curves or
objects on the road.
Speed increases the likelihood of crashing.
Speed increases the severity of a crash once it occurs. (The energy
involved in a crash is proportional to the square of the speed, so if the
speed doubles the energy involved goes up four times.)
Advice for Drivers
Drive within the speed limit and at a speed consistent with road
conditions.
On high speed roads always leave a 2 second gap between your car and the
vehicle in front.
