Most collisions are caused by driver error. Less than two
percent of collisions are the result of a mechanical problem
with a The Collision Investigation Unit is on hand to
investigate any fatal road traffic collisions or ones in which a
person has When the unit is called to a collision, they will
seal off the scene and start to investigate. “We are trained to
look for specific evidence such as tyre and scratch marks on the
road surface, but there is an abundance of information that can
be collected at the scene,” explains PC Mike Baddeley from the
Collision Investigation Unit. Officers rely on maths and physics
and the laws of motion to make their calculations and must
undergo special training in these areas to join the “The
evidence is interpreted and used to reconstruct the collision.
We can often show how a vehicle was moving – was it swerving,
had the driver control of the vehicle? In addition, we can often
calculate the speeds of vehicles at the time of the collision
quite accurately” All marks are phot
