Cameras 'to catch 20mph speeders'

Drivers breaking 20mph limits could be caught by new speed cameras if the government accepts advisors' proposals.

Local authorities are keen to introduce the cameras, a report by the government's advisors on transport safety says.

The devices measure a driver's speed over a certain distance and should be a priority for the Home Office, it says.

The report also argues for more 20mph zones in built up areas and a target to cut road deaths by half.
