Traffic on Britain's most congested roads suffers average delays of more than 12 hours a day, experts have revealed.
A survey completed by navigation company TomTom discovered that Bedford Road in Clapham, south London, endures the worst jams, with an average of 92 hours a week or more than 13 hours a day.
The Kingsway Tunnel Approach in Wallasey, Merseyside, is the next-worst route as those heading into Liverpool face an average of 90 hours of jams every week. The B5159 Warburton Bridge Road in Warburton, Greater Manchester, is the third worst offending road with bottle-necks for around 86 hours a week.
Motorists can double check the worst offending roads against theirjourney planner to avoid delays during peak times.
TomTom experts analysed congestion across the UK's roads over the last two years to compile the figures as part of a traffic manifesto to reduce congestion.
The top 12 worst roads in the 25-strong list force delays for at least 84 hours a week, while the remaining 13 routes frustrate road users for around 81 and 83 hours every week.
These are the top 10 congested roads from the TomTom research with the number of hours each route endures in delays a week:
