WITH reference to average, fixed speed cameras and mobile, police safety camera vans. (Craven Herald letters). Mobile cameras have to be well signed and visible, and are limited as to where they can be positioned due to safety requirements. Added to that they don’t operate at night - again due to safety issues. So the element of surprise is reserved for the driver not paying attention - but most are warned by other drivers.

Unlike a fixed camera, mobile cameras go home and so speeding resumes immediately. At least a fixed camera keeps on reducing the speed at that point, but does little for the overall speeding issues on a stretch of road. Average speed cameras enforce speed over long stretches of road, as opposed to a small area covered by either a mobile camera (daytime only) or fixed camera.

North Yorkshire road casualty statistics are worse by 40 per cent when the national average shows improvement. Not something to be proud of.

The danger presented by speeding, anti-social driving and the associated noise subjected upon residents is unacceptable. Don’t speed and you won’t have to pay any fines.

22 councils have united to ask for North Yorkshire to change its policy and push for average speed cameras to improve road safety and have appealed to the mayor and deputy mayor to take action.
