Sitting in traffic is something we can all say we've done at least once and a new study shows us just how long we do it and how much it costs. In Chattanooga, drivers spend an average of 28 hours, per year, per person waiting in traffic. Going through that costs about 730-dollars per driver each year. In Cleveland, drivers are delayed 13 hours individually. It costs those behind the wheel about 294 dollars per year. Now comparing that to Knoxville, right up the road, approximately 35 hours are spent sitting in traffic per person costing each driver 849 dollars per year.
