Watch out D.C. drivers, the District is deploying four new photo radar cameras for “final testing.” That means that while the cameras will flash and take your photo if you are speeding, you will not be issued a ticket.

Here are the locations, according to the Metropolitan Police Department:
— 5400 block of 16th Street NW
— 100 block of Michigan Avenue NE
— 2800 block of Benning Road NE
— And up in the Palisades, where some residents have complained that the 25 mph speed limit on MacArthur Boulevard is far too slow, the District is setting up a photo radar camera on MacArthur near 47th Place.

D.C. only has one stationary photo radar camera right now, along Florida Avenue in Northeast, but there are mobile photo radar enforcement zones and red light cameras.

We can only hope that the continued introduction of speed cameras does not lead to violence, as it has in Lancashire, England.

Closer to home Virginia’s General Assembly may let the commonwealth’s 10-year red light camera testing period sunset in June. There is one Virginia Beach Republican who is fighting to “keep it alive” past June, according to a Virginian-Pilot editorial in support of red light cameras.
