Window Tint Laws in Maryland and D.C.

Window tints laws require a significant amount of light to be transmitted in car windows. Once pulled over, a police officer may check to see if your car’s window tints are legal or not. You may ask yourself how police officers can do that. In addition to knowing how to check for too much tint, you must know the window tint laws in both Maryland and D.C.

How do the police determine if a window has too much tint?

The only way to determine if there is an actual violation of the statute is for the officer, after stopping the vehicle, to conduct a test utilizing a “two-piece window tint meter.” When observing a vehicle without the benefit of such a device there is no definitive way to determine if the window tint on a car is in violation of the statute other than by eyeballing it.
