So if i am reading this site
correctly and they are updated to current va/md specs. The only difference is MD allows 35% for fronts where as VA is 50% and both allow up to 35% for the rear windows.
I'd say you should be fine having 35% on a car with MD plates, but if a VA cop really has it out for you then he could still probably cite you for it. The chances of getting a tint related ticket are always pretty low in my experience. There is also not a huge difference between 35/50 imo, although i do like 35 better
