One in four cameras on junction 34 of the M1, where there have previously been fatalities, were also found facing the wrong way or broken.
One in four cameras were also hit by issues on a section of smart motorway operating on the M3 in Surrey.
Cameras were seen pointing at the ground or even the sky instead of some of the UK’s busiest routes.

“We are, however, investigating these allegations as a matter of urgency.”
