DBC (Distance Between Cars) Specifications

Firmware Code Details:

Distance Between Cars (DBC) is defined as the "back-to-front" bumper separation between two vehicles. The actual point of measurement is front-to-front bumper, but with an assumed average length of a vehicle (13 ft), the firmware can determine a valid calculation that is actually in favor of the violator. When in DBC mode, the laser is used to capture and display the speed of the front vehicle. The trailing vehicle is then targeted. Upon completion of the second measurement, the laser displays both the time and distance between vehicles.

Hardware Requirements:

Tailgating firmware is only available in the UltraLyte 100 LR and TruCAM® models.

Requirements to use DBC technology:

  • Must be a certified LIDAR operator with minimum 16 hours of field use
  • DBC classroom training with basic principles
  • DBC field training (complete 100 measurements)
  • Operation certificate to be issued after training

Suggestions on how to get DBC adopted in your state:

  • Launch a public awareness pilot program and get local media involved
  • Educate the courts about this technology in advance
  • Issue citations with Time Between Cars (TBC) at one second or less
