The recent thread about a laser only detector got me thinking. Would a unit only capable of receiving laser signals be legal to operate in Virginia and DC?
I would imagine the statute was written before LIDAR was invented or in common use. If the language used in the statute is specific enough to ban "radar" detecting devices, I could see a loophole that someone could potentially argue if caught with a laser only unit.
EDIT: Just wanted to add that I know laser only detectors are pretty scarce these days and that any new detector is going to be a combo unit. So, I suppose this scenario is more of a hypothetical situation.
