Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps his Department is taking to help ensure that speedbumps are constructed to correct dimension specifications.

The Department for Transport provides detailed guidance to highways authorities on the design of traffic calming measures in Local Transport Note (LTN) 01/07 ‘Traffic Calming’, which is available on gov.uk. The Highways (Road Humps) Regulations 1999 provide the statutory framework for road humps in England and Wales.

Decisions on installing road humps are matters for the local highway authority, and they do not have to notify the Department of these decisions. Should there be concerns about specific road humps, members of the public should raise this directly with the local authority responsible for their installation.
