Britain's scariest roads revealed

The top three scariest roads were Spaghetti junction in Birmingham, the M8 in Glasgow and Marble Arch in London

Spaghetti Junction in Birmingham has topped a survey of Britain's scariest road systems.

The poll for breakdown firm, Britannia Rescue, placed the M8 junctions through Glasgow in second with London's Marble Arch taking third spot.

Between them, Birmingham, London and Glasgow took eight of the top 10 spots.

The survey of 3,225 drivers found that as many as 8% avoided "scary" junctions altogether and drove an average of 238 miles extra each year on detours.

The poll also showed that 2% of motorists are so nervous they avoid making right turns at all costs, while 14% do not go near urban areas.

Large roundabouts were considered to present the most confusing aspect of urban driving, followed by one-way systems, speed bumps, cameras and box junctions.

Some 21% of drivers said they were more concerned about breaking down at an intersection than at any other point.

A quarter of those surveyed also said that many road junctions were badly designed.

Britannia Rescue general manager Simon Stevens said: "All drivers have to deal with particularly hairy intersections from time to time.

"But what this research shows is that badly designed and confusing junctions are spoiling the driving experience for many motorists.

"Some will even drive hundreds of miles out of their way every year to avoid difficult junctions. We urge motorists to familiarise themselves with tricky road junctions so that they are better prepared when they have to use one."
