Got stopped on I-95 yesterday doing 77 in a 65. Cop was nice enough to let me go with a warning for the speeding, but gave me a repair order because, according to him, my windows were tinted beyond that which Maryland allows (35% minimum light penetration).
Having done some very basic research, I learned that it takes a light meter to properly gauge how much light tinting allows through. Tomorrow I'm taking the car in to find out if he was right, and if so, to get it removed.
Is it really that easy to see the difference between 35% and, say, 20%? The cop used no equipment to do his testing. He just said it was so and that was that. I didn't bother arguing. Just said thanks and drove off.
