Motorists who speed will be targeted by officers from the road policing unit as part of a week-long national campaign which relaunches today.

Extra checks by officers in Bedfordshire, Cambridgeshire and Hertfordshire will be carried out between today and Sunday as part of the second TISPOL speed campaign.

The first initiative in April saw 39,231 vehicles caught breaking the speed limit in the UK, with both marked and unmarked cars to be used again to catch offenders.

Insp Mark Rogers said: “I would urge anyone to drive within the lawful speed limits. However, I would like to point out that it is not always appropriate to drive at the speed limit depending on the road conditions. The limit is not a target.”
