The average city motorist is immobile for just over 25 minutes of their journey to work, an increase of 10.9% in the past two years, according to a study commissioned by Citroen.
The manufacturer surveyed drivers across five UK cities and found that Cardiff commuters suffered the longest standstill – remaining stationary for more than half of an hour long journey.
However, Cardiff motorists did manage to cover a greater distance than drivers in other cities while they were moving, travelling an average of 16.3 miles.
Drivers in Manchester spend the second longest period at a standstill, remaining stationary for the average time of 25 minutes, despite having one of the lowest journey distances.
London motorists fared better, spending just over 24 minutes stationary.
Surprisingly, motorists in the capital are also covering nearly twice as many miles as they did in 2006.
However, London drivers are also sending around five minutes longer stuck in rush hour traffic than they were two years ago, seeing the greatest increase in time spent stationary than any other city.
Norwich commuters experienced the shortest journey of all, as well as spending the least amount of time stationary.
The AA has launched motorbike patrols in five major cities, including Birmingham, Sheffield and Manchester, after a successful trial in London.
During the trail the AA found that its team motorbikes reached breakdowns at least a third quicker than vans.
Edmund King, president of the AA, said: “As up to 15% of drivers are stuck in queues during the morning peak, we want to make sure that our patrols are not stuck in the same queues.
“In our experience two wheels are better than four at beating congestion.”
