All of Western Avenue is enforced by DC police. It is the dividing line beteen DC and Maryland but I think the road itself belongs to DC. The speed limit in DC is an amazing 25 miles per hour unless otherwise posted. If you are traveling on this stretch of road you better be going under 30 miles per hour. I have received a ticket from a DC officer with hand held radar parked along the South side of Western Avenue near the small market and I have received a photo ticket along this strip. There used to be a phot radar car there all day every day but I think everyone now must know about this trap because almost everyone does only 25 miles per hour and no one rides on anyones’ bumper. This must have been the biggest money maker in the District.
