Sergeant John Naccarato of Clackamas County, OR has performed extensive field testing and has taken the initiative to execute a pilot program with a new technology called DBC (Distance Between Cars). This patented software code is programmed into LTI's UltraLyte 100 LR speed laser and provides officers with the ability to collect accurate measurements between vehicles, both in distance and time. This data allows an objective argument to be made, using the vehicle’s speed, perception, and reaction time to determine a safe following distance.
Until now, only visual observations could be made by the traffic officers to determine if a vehicle was traveling too closely behind another vehicle. Since adding DBC technology to their speed lasers, Clackamas County has issued about 200 violations for speeding and for following too closely. According to NHTSA's Fatality Analysis Reporting System, "the economic cost of speeding-related crashes is estimated to be $40.4 billion each year". Sgt. Naccarato is one of many advocates of this new technology in the U.S. Other states are adopting DBC technology and beginning to promote tailgating enforcement campaigns through the local media and electronic billboards placed along the highways.
