Mark this: UK roads suffering from fading white paint
Scotland is suffering the worst with the disappearing road marking problem – as many as 40 per cent of markings on the country's motorways and dual-carriageway roads need immediate replacement.
And 40 per cent of markings on dual carriageways in Wales also need immediate replacement, a survey by the Road Safety markings Association found.
Looking at more than 4,500 miles of white lines across major routes in Britain, the survey found that 38 per cent of English motorways and 36 per cent of Highways Agency-maintained English dual carriageways were in need of immediate or scheduled repairs.
Roads Safety Markings Association national director George Lee said: "Our report shows that national standards are not being enforced and that the quality of road markings is declining at an alarming rate."
"We strongly suspect that the layers of bureaucracy built into the system of maintaining HA roads is stifling results. Taxpayers are paying, but the funds are simply not going on the roads."
According to the survey, the poorest stretch of English motorway for road markings was the M6 between Wigan and Standish, and the worst dual-carriageway stretch in England was the A630 from the M1 to Sheffield.
The worst HA-controlled single carriageway was a stretch of the A49 between Standish and Chorley in Lancashire.
Wales' worst stretch of dual carriageway was a section of the A5156 at Wrexham while the worst single carriageway was the A466 Chepstow (in England) to Monmouth (in Wales).
In Scotland the worst motorway was a north-bound section of the M90 between Dunfermline and Perth, while there were poor markings on the A92 Dunfermline to Kirkcaldy, and on the A8 and A720 near Edinburgh.
RAC technical director David Bizley said: "If the findings of this survey are correct it is clearly a cause for concern as road markings are an essential safety feature.
A spokesman for the Highways Agency said: "We conduct our own annual surveys to assess the condition of road markings on the strategic road network, to ensure that journeys can be made safely and reliably.
"The survey was not comprehensive, and it is not clear how they chose which parts of our network to survey. Furthermore, they misquote the standards for quality of lane markings within their report."
