According to a new survey by the RAC, twenty-three per cent of drivers have admitted to having disregarded the red X sign on smart motorways.
The survey of 2,093 members of the RAC Opinion Panel* who had driven on a motorway in the last year confirmed more than eight in 10 drivers (84%) had seen a red X appear on the verge-mounted or overhead gantry electronic variable message signs, and have disregarded this either occasionally accidentally (19%), accidentally (1%) or occasionally on purpose (3%).
Among those, there is no doubt whatsoever as to the meaning of the red X with 99% saying that it signifies the lane is closed.
Hundreds of miles of smart motorways across England now use the hard shoulder as either a permanent or part-time running lane.
