Drivers on Colorado highways have been caught illegally crossing in or out of express lanes 361,451 times over the past eight months – more than 1,400 violations per day. The Colorado Department of Transportation has issued $42 million in fines, state records show. The automated enforcement system that CDOT officials launched a year ago – a network of roadway surveillance sensors, cameras, and driver tracking technology — gradually is changing behavior, agency officials told the Denver Post. Express lane transgressions are decreasing “and 81% of violators do not incur a second violation,” CDOT spokesman Tim Hoover said. But state data shows a problem: people driving “way too fast” in express lanes and in the other lanes, Hoover said. “The complaint we hear is from people driving the speed limit, or even slightly over, who are tailgated by speeders behind them — speeders who, before enforcement, were wantonly weaving in and out of the express lane to swerve around other cars,” he said. Sometimes, drivers also complain that cars in express lanes move slower than the speed limit, delaying express lane drivers who have paid for the access and expect to travel faster.
