Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 9 March 2023 to Question 158934 and the Answer of 20 March 2023 to Question 163764 on Road Traffic Control, what assessment he has made of the effectiveness of redundancy systems for National Highways’ CHARM system in the context of the outage on 22 February 2023.

On rare occasions, the nature of a failure may prevent the operation of CHARM for longer periods of time and when this happens National Highways has well-rehearsed procedures in place to help ensure the safety of road users, such as increased patrols and CCTV monitoring. Safety remains our priority and National Highways investigates every outage to ensure that steps are taken to prevent future occurrences.
