New laws typically take place with the start of the new year, but one law that was already on the books is to be getting a larger dose of enforcement.

Starting January 1, people who have tinted windows in their vehicles will have to pass a test showing their tint isn’t too dark or fail vehicle inspection.

Law enforcement officers have long complained that windows that are too dark prevent them from seeing in the vehicle in the course of a dangerous traffic stop or even a crash to determine who is in the vehicle and might need help.

Officers say the violations go largely unenforced unless they are looking for other issues since police have many more crimes that take a higher priority.
