Do the cameras photograph every vehicle that passes by them?
The photo radar system takes photographs of only those vehicles that exceed the program’s speeding threshold (although the system does collect basic data about the speed of every vehicle that passes through the radar beam). The MPDC uses photo radar to target the most serious and dangerous offenders and to issue citations to vehicles demonstrating disregard for public safety according to District of Columbia laws and regulations. The system operators are radar-certified police officers, working in an overtime capacity.
