Traffic Unit / CCRLEC Crash Reconstruction Team

The Traffic Unit is comprised of a Sergeant and a patrol officer and operates a fully marked Police Utility vehicle equipped with the latest RaDAR and LiDAR technologies. Being part of the patrol force, the Traffic Unit is responsible for the investigation of Serious Injury and Fatal Motor Vehicle Crashes. The members of the Traffic Unit are certified Traffic Crash Reconstructionist with advanced training in the investigation of Motor Vehicle Crashes, Motorcycle Crashes, Pedestrian and Bicycle Crashes, Heavy Truck Crashes, and Human Factors in Motor Vehicle Crashes. Each unit member is also on the Cape Cod Regional Law Enforcement Council Traffic Crash Reconstruction Team. As part of that team, we assist other police departments on Cape Cod with investigation of Serious Injury and Fatal crashes.

In town, the Traffic Unit is responsible for deploying our 4 portable radar signs that monitor and record vehicle counts and speeds. This data is then analyzed to determine when and where the most frequent speeding violations are occurring. This information is used for coordinating targeted speed enforcement. In addition, the Traffic Unit investigates complaints of unregistered vehicles and sight line issues at intersections, Impaired Driver Enforcement, Crash Prevention, Statistical Crash Data Analysis, and responding to citizen complaints. We work closely with the DPW to improve roadway safety for all of our residents and visitors.

One of our officers is also a Child Car Seat Installation Technician and can assist with the installation of, or checking the installation of Child Passenger Seats. Please visit the Community section of this website to request placement of the portable radar signs. For Child Passenger Seat installation or inspection, or other traffic related questions or concerns, email Officer Mark T. Holmes at mholmes@harwich-ma.gov.
