Since regional law enforcement includes DC, along with the Maryland State Police and Virginia Highway Patrol, seven county(4-MD, 3-VA), seven city(DC, 2-MD, 4-VA), and nine university(Univ. of MD, Univ. of VA, Univ. of DC, American Univ., Howard Univ., Gallaudet Univ., George Washington Univ., George Mason Univ., Marymount Univ.) police forces. I thought I would ask each one about their respective policy on the 'close passing law for their respective state(and DC).
I have heard back from the Police Chief in my county who gave me a 'standard' answer.
But when I talked with a Sgt. with the City of Fairfax, I not only had a terrific conversation with the officer. He is a cyclist himself and definitely supported having a helmetcam. Saying that would definitely help in getting a violator(of course that is presuming the cyclist gets' the license plate number). He did say one thing that bothered me. When they changed their computer system in 2006, that since then, they have not filed charges against driver involved in a collision with a cyclist.
My curiosity stems from the reactions I have seen from officers' with city, county, and state police.
