Fairfax Co. Police have stepped up enforcement on this road due to a accident involving a car striking a pedestrian in the crosswalk outside the L2 North garage exit of the Vienna Metro. Exiting the garage, there are no posted speed limit signs. The speed limit (per the officer) is 30MPH, but traffic regularly flows at 40MPH+. It was clearly evident that the posted limit is not ‘well known’ because the officer directed another motorist to stop while he had ‘someone’ pulled over with his lights on.
