"Lives were put at risk" after important safety technology failed across a string of UK motorways, it has been claimed. Stretches of roads in Yorkshire and the North East, the Midlands, Greater Manchester and the South West were affected by the issues on Saturday.
A whistleblower said lives could have been lost as a result of the problem which saw National Highways "temporarily losing the ability" to set motorway signs and signals. However National Highways chiefs insisted procedures to deal with the outage were set in place.
It added there were no reported emergency incidents during the period which ran from 12.35pm and lasted under of two hours. "This was resolved after one hour and 45 minutes," said National Highways in a statement.
