Thousands of roads in Tayside and Fife are on red alert for repairs, Transport Scotland figures show.
Of the 67,548 routes maintained by councils in the area, 3,337 “deteriorated to the point at which repairs are likely to be required to prolong its future life”.
Nationally, the report revealed that car and train use increased in 2017-18, while the number of bus journeys fell.
John Finnie, the Greens MSP, said the figures expose Scotland’s car dependency and demanded those who oppose allowing councils to charge a car park tax should “seriously reflect on their position”.
Transport Secretary Michael Matheson said: “Although the majority of public transport trips are made by bus, I remain concerned that bus use continues to fall – and this is a trend we see across the UK.
“We are continuing to spend over £250 million a year to support our vital bus industry.”
Just 3% of Scots usually cycle to work, while 67.7% of people commute by car, the Scottish Transport Statistics 2018 show.
Scottish Liberal Democrat Mike Rumbles said: “Sadly the figures highlight how little the Scottish Government is doing to promote active travel in Scotland.”
The report published on Wednesday also found that councils in Courier Country had spent £78m on roads and transport projects in 2017-18.
That is up 18% on the previous year’s capital expenditure.
