Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has set a minimum acceptable level red-X non-compliance on smart motorways.

There is no acceptable level of red-X non-compliance and Highways England are working to reduce non-compliance to as low a level as possible.

In partnership with the Police, Highways England have issued over 160,000 formal warning letters across different Smart Motorway locations to drivers identified as wrongly using the hard shoulder or contravening red-X signals. Their judgement is that these letters are having a positive effect, with repeat offences declining significantly.
