More than nine out of ten Scottish motorists say roads are worse now than they were a decade ago, according to a study.

The survey of AA members found that 91 per cent north of the Border believe residential streets where they live have deteriorated since 2008.

Scotland was the joint worst in the UK, along with the North West and East Midlands, suggesting roads north of the border have degraded to a greater extent than elsewhere.

Across the UK, 88% on average said roads were worse.

Edmund King, AA president, said: “It is clear that despite all the talk from central and local government, not enough is being done to fix our increasingly dangerous streets."

The findings come after it emerged in October that roads in Scotland are pockmarked with the highest number of potholes in the UK and have a combined depth of nearly four miles.

Data collected by insurance firm revealed a total of 154,310 potholes were reported to Scottish councils the previous year - around 16,000 more than the next worst-hit area, the south west of England.

It means Scottish motorists are reporting around 423 cavities each day, three times more than counterparts in London.

Estimates also suggest it will cost £2.25 billion to bring Scotland’s roads up to scratch and with councils continuing to tighten their belts, that repair bill may continue to rise.

In Scotland, some 73% of those who took part in the AA survey said roads had deteriorated “considerably” in terms of surface and potholes, compared with 67% across the UK.

Only 2% north of the border claimed their roads had improved compared with a decade ago.

More than half (51%) of respondents rate their roads as “poor” and 7% say they are “terrible”.

“Our potholed roads are in a perilous state," said Mr King.

"AA breakdown operations are rescuing record numbers of drivers whose tyres or wheels are damaged by potholes.

“The current lack of proper investment on local roads means that highway authorities are doing little more than papering over the cracks.”

The Scottish Government said previously that the most recent Audit Scotland report on roads maintenance found 80% of the network was in an acceptable condition, with the maintenance budget for trunk roads increasing to over £199 million in 2017/2018.

Officials said the additional funds would allow more repairs to be carried out to road surfaces to address potholes and other defects, as well as safety checks on bridges and other infrastructure.

It was calculated last year that the UK's potholes have a total depth of more than 24 miles, which is almost four times deeper than the Pacific Ocean.

Industry sources said at the time that one in six local roads would need to be repaired or may even face closure within the next five years due to poor maintenance.

The Local Authority Road Maintenance survey, produced by the Asphalt Industry Alliance, found that 17 per cent of all roads were at serious risk of closure unless they are repaired by 2022.
