Many road markings 'barely visible'
Some of Britain's most dangerous roads have white line markings which are completely worn out, according to a new report.
On one stretch of road - a five-mile section of the A6135 near Sheffield - just 1% of the markings were in good condition.
The report, released by the Road Safety Marking Association (RSMA), assessed more than 1,500 miles of motorways and A-roads. It said two-thirds of all UK road deaths and serious injuries occur on rural A-roads.
Yet, of more than 60 single-carriageway A-roads surveyed, totalling more than 1,000 miles, on average 14% of road markings were completely worn out and a further 15% were in immediate need of replacement. Just 29% of white lines reached the acceptable level of visibility, said the report.
On the five-mile section of the A6135 between Ecclesfield and junction 36 of the M1, three-quarters of the markings were either barely visible or needed an immediate schedule for replacement.
Two other sections of road had nearly half their marks worn out - the A645 in Yorkshire/Humberside and the A509 in Northamptonshire.
Two roads in relatively good condition were a 14-mile stretch of the A1133 in the East Midlands, where three-quarters of the road markings were up to the standard, and 10 miles of the A63 between Leeds and Hull, which almost matched this figure.
Top marks went to a section of the A303 dual carriageway in Somerset which had 86% high-quality markings and a section of the M65 in Lancashire with 91%.
Of the 470 miles of major A-roads and motorways surveyed, 20% fell below the minimum specifiable standard and should have been scheduled for replacement, while 8% had centre line markings so worn that they were barely visible.
A total of 39% of markings on dual carriageways and 38% on motorways made the recommended rating used by the industry. But the report said there had been a significant drop in the quality since 2008, when 69% of markings on dual carriageways reached this grade and 49% on motorways.
