[Poohbah]

I think it only applies to Maryland.

That's the way I read it also, so the reference to the stops being "unconstutional" refers to the MD constitution. It's nice to have a precedent, but it seems out of character for that state.

Poohbah is correct (I think) - MD is more restrictive than the Sitz opinion. I haven't checked into surrounding states as I don't plan on needing to know. I don't know how VA has structured their's - you would do well to check with an attorney that specializes in DWI cases before you encounter your next roadblock...
