A new type of speed camera is to be used to enforce the national speed limit. The first camera – Hadecs3, is due to be used on the M25 by the summer of 2014 and further afield over the next two years.
It could be the biggest change to the way speed limits are enforced since the introduction of the 70 mph speed limit in 1967.
A recent survey for Autocar magazine found that 94.6% of drivers admitted breaking the limit.
The Hadecs3 requires no white markings to be painted on the road and will be grey instead of the bright yellow. It is cheaper to maintain than conventional speed cameras because it does not need road markings or film (it digitally downloads). Instead of using painted white lines to give a backup calculation of a car’s speed, each Hadecs3 box contains two radars that give independent readings.
