A motoring expert has advised motorists to 'queue-jump' in order to ease traffic jams.
Peter Rodger, chief examiner at Institute of Advanced Motorists (IAM), said patiently waiting in queues for vehicles ahead to move might seem to be the right thing to do, but it only adds to the traffic jam.
He suggested drivers make use of available lanes and take turns to join the single lane where possible.
"This reduces the length of road the queue stretches along and prevents blocked junctions," Mr Rodger said.
But he added that drivers in long queues of traffic may frown at motorists who "zip merge" to avoid long tailbacks.
Mr Rodger continued: "If you are approaching a long queue of traffic in only one lane, you should stay in the lane you're in, even if it's empty, as long as you reduce your speed. Even if you have to merge further down, it is worth using all the space available to avoid unnecessarily long tailbacks.
"When travelling alongside a queue of traffic keep your speed right down and be extra vigilant, as other drivers may be considering pulling out into the empty lane."
