How to Avoid Traffic Jams

Jim Nockersey travels to the most jammed motorway in the country. He finds a traffic shockwave that moves backwards down the carriage way. No matter what motorway you're on, or what speed you're travelling at, the shockwave always moves backwards at approximately 12 miles an hour. If there's a huge queue of cars behind you slow down and that will have an effect on the cars behind you as well. Low-level road rage incidents may occur during this programme. But it could have been a lot worse because imagine you were stuck in the longest lasting traffic jam in the world.
