National Highways reply:

In a statement National Highways disputed claims cameras were not working ‘for hours’ at a time and claimed alternative systems were available when any technology issues occurred. It also disputed it was seeing significant staff absences, but said it was facing a ‘challenging’ labour market.

Andrew Jinks, National Highways regional director for the Midlands, added: “We have robust and well-rehearsed mitigation measures in place to deal with any operational challenges facing our network, including those related to technology and staffing, and it is inaccurate to claim cameras are not working for hours.

“Safety remains our number one priority and an independent investigation is under way to help prevent a recurrence of the recent system issues.

“Our staff are passionate about their jobs and we acknowledge the frustrations with these system issues. We will ensure any staff concerns are listened to and that they are fully supported in their roles.”
