Highways England published evaluation reports for the first three years of the operation of the M25 junctions 5-7 and 23-27 all lane running schemes on 16 July 2018. This included information on non-compliance of red X lane closures.
They indicate an overall red X compliance rate of 94% on both schemes, improved from 93% in the one-year reports. This was measured as a percentage of the total traffic flow during a sample of red X lane closures.
Red X compliance is vitally important, and the majority of drivers obey the signals. Highways England continue to work closely with the Police to issue warning letters to drivers who fail to comply with a red X, as well as developing a range of customer information campaigns. Enforcement of red X violations using automated camera detection is planned to commence in 2019, meaning that anyone who drives through a red X will risk being fined.
