Large parts of the smart motorway network in England were hit by a two-hour software failure on Wednesday.
The problem, which froze signs and signals and deactivated the stopped vehicle detection system (SVD), lasted from about 08:30 to 10:30 GMT.
National Highways said it was "urgently investigating" the problem.
Outage prompts investigation amid calls to axe smart motorways
Why on earth a Safety Critical system like this doesn't have some form of back up mode or, at least, a "fail safe" setup that would post caution warnings on all the signs if the computer systems failed, I don't know.
(Well, actually I do, it's because that would cost more than the expense of cleaning up if there were any accidents if the system failed...)
