The A686, which runs from Penrith over the border to Haydon Bridge in Northumberland, was ranked among those with the least traffic – making them among the most enjoyable to drive.
It comes following research by Avis Car Rental UK, which analysed the annual average daily flow (AADF) produced by the Department of Transport from nine regions.
AADF figures give the number of vehicles that drive on a particular stretch of road on an average day of the year.
Avis’s league table showcases the quietest A roads in Britain, defined by the lowest amount of vehicles per km, per year.
Nina Bell, from Avis in the north, said: “We want to help our customers experience the real joys of driving with limited disruptions and stresses, such as traffic and busy city centre routes.
“Now they can drive ... where the only distractions are the fantastic and remote landscapes.”
It is not the first accolade to be given to Hartside Pass – which runs through Alston and down onto the A69 – as it was named as One of the Greatest Drives in Britain by the AA last year.
The spectacular road also captured the imaginations of Tour of Britain organisers last year, who chose to finish a leg of the world cycle race up the seven per cent incline.
The race was televised globally, attracting positive comments on the scenery and views.
A spokesman for Avis said: “We hope the research results will encourage customers to experience the real joy of driving by avoiding traffic.”
Top of the rankings was a single track road in the Scottish Highlands, with the A481 in Powys, Wales taking second place and the A3079 in Devon coming in third.
