The North Circular has been named the most congested road in London, with a staggering 56 hours of delays on the northbound carriageway every year, according to new research.
Data from the Department for Transport has been analysed by Go Compare to uncover which roads, cities and motorways drivers should avoid if they're in a hurry.
A number of west London residents will be all too familiar with traffic chaos on the North Circular, and the data suggests there are more than two days' worth of delays on the road each year.
Research also found that London is the most congested city in the UK, with motorists on average being stuck in traffic for a total of 73 hours each year in the capital.
London was also found to be the city with the second most traffic congestion in all of Europe, only being knocked off the top spot by Moscow - where there are 91 hours of traffic each year.
Paris and Istanbul follow after London, with 65 and 59 hours of congestion respectively.
