Highways England published comprehensive evaluation reports for the first three years of operation of the M25 junctions 5-7 and 23-27 all lane running schemes on 16 July 2018. These included information on non-compliance and on a programme of work designed to improve Red X compliance.
The evidence indicates an overall improvement in the Red-X compliance rate on both schemes between the three-year and one-year reports. The majority of drivers obey Red-X signals. Highways England continue to work closely with the Police to issue warning letters to drivers who fail to comply with a Red-X signal, as well as running a range of driver information campaigns.
