Question to the Department for Transport:

To ask the Secretary of State for Transport, whether the gantry cameras on the M1 motorway in Nottinghamshire and Hertfordshire are only used to police the variable speed limit when operational in those areas and for no other purpose.

The gantry cameras on the M1 in Nottinghamshire and Hertfordshire are provided to encourage compliance with the variable mandatory speed limit when operational.

The operation of these gantry cameras for enforcement purposes is a matter for the Hertfordshire and Nottinghamshire police respectively and may include enforcement of the national speed limit as well as the variable speed limits.
