Question to the Department for Transport:

To ask His Majesty's Government, further to the Written Answer by Lord Davies of Gower on 11 December (HL579), what percentage of lamp columns on each major motorway are out of light, how often lamp columns on motorways are inspected for such issues, and within what period of time they expect defective lamp columns on each motorway to be repaired.

National Highways does not centrally hold aggregated information on the lamp columns out of light for the whole of the motorway network.

National Highways inspect lamp columns on motorways every 28 days. Where defects are identified, the nature and priority of the fault(s) will determine the timescales in which they are repaired, with most simple faults being repaired within 14 days.
