Is it true that having a car with a tinted windshield is illegal?

Laws differ from state to state, but it’s generally illegal to completely tint a front windshield in the United States. Remember, it’s the customer’s responsibility to adhere to the law when they operate their vehicle, not yours. That being said, if a customer requests a window tinting service that prevents their car from being street legal, let them know you’re not responsible for anything that happens.
