Abstract
A device, and an associated method, for determining separation distances separating motor vehicles travelling along a roadway. A separation distance separating the motor vehicles is calculated responsive to targeting the vehicles with a laser range finder and determining the speeds of the vehicles. From this information, the separation distances separating the motor vehicles can be calculated. If the separation distance separating the motor vehicles is less than a minimum distance, then the calculated separation distance can be utilized by traffic enforcement officials to take appropriate enforcement actions.
