There's a fixed LPR at the SW corner of  West VA Ave & Mt Olivet St NE, and another at NY Ave NW @ New Jersey Ave. 
I was in my company vehicle last year and was pulled over after I passed the fixed LPR on Benning RD. My vehicle was flagged as being stolen. The police officer just waited for me at Benning & H. After he saw that the vehicle wasn't stolen, he let me see his MDT. It showed a photo of my vehicle as I passed the LPR. 

DC has also installed LPR's on the street sweepers to automatically ticket vehicles parked on street cleaning days.
