Police yesterday vowed to carry out a “day of action” seeking out rogue drivers each week in a bid to improve road safety in London.

More than 300 key junctions will be targeted alongside a poster campaign to highlight winter dangers in advance of the clocks going back on Sunday.

The initiative was launched today ahead of the switch-on of new motorway-style average speed cameras on the A40 next week. The cameras are also being installed on the A406 North Circular Road, the A316 and the A2, where they will enforce speed limits from early next year.

Today’s crackdown will target speeding, careless driving, red-light jumping, drink and drug driving, using a mobile phone while driving, driving without a licence or insurance and driving a dangerous vehicle.

The number of people injured in road collisions in Greater London last year rose 13 per cent on the previous year to 30,785 casualties. The number killed fell from 132 to 127 and the number killed or seriously injured fell seven per cent to 2,167 – the lowest figure ever recorded.

Detective Chief Superintendent Paul Rickett, of the Met’s roads and transport policing command, said: “The impact on victims and their families of serious and fatal collisions cannot be overstated. Targeting our activity on the causes of collisions… is proving extremely effective.”
