Dear Department for Transport,
There is a well known direct correlation between severity of injury and traffic speed. The Government’s own advertising campaigns majors heavily on the injury differences between 30 mph & 40 mph to emphasise the point.
The effectiveness of cameras in reducing speeds to within legal limits is equally well established, but they cannot be deployed on a preventative basis. The rules only allow their use once there is a suitably severe accident/death history, which of course is too late.

What information is available that explains why their use is restricted in this way? It is the logic behind banning their use on a preventative basis that I want to understand, so please don’t just refer me to the rules – I want to know why they exist.

Yours faithfully,

Rose Cullingford

Dear Jeff Gilmore,
Many thanks.
