Written question asked by Lord Monson (Crossbench), in the House of Lords. It was answered by Lord Adonis (Labour) on Tuesday, 14 July 2009.

Roads: Speed Humps

Question: To ask Her Majesty's Government whether they intend to outlaw speed humps on public highways which cannot be traversed at 15 mph or less without risking hidden damage to the vehicle or its tyres, or harm to vehicle occupants (including ambulance patients) and motorcyclists.

Answer: Local highway authorities already have powers to place and remove road humps on their roads where appropriate. The Highways (Road Humps) Regulations 1999 set out the permissible dimensions for road humps. Road humps must be a maximum of 100mm in height, although the department recommends local authorities consider using road humps 75mm in height to ensure those vehicles with low suspensions do not suffer from grounding. There are no plans to amend these regulations to reduce the maximum permissible height of road humps.
