If you think one window tint is like another, try again. Depending on the state, laws can vary widely on which panels can be darkened and by how much. Here’s a quick sampling of the laws in different state jurisdictions to show just how uniquely the issue is treated across the country. It can make a big difference on that cross country road trip!

California

Well known for its strict safety regulations, especially when it comes to motor vehicles, the Golden State has one of the most burdensome window tint laws in the country. As in most states, the rear side windows and the rear window are not subject to any darkness restrictions, but they cannot be more reflective than a standard screen, which means that a mirror finish will give you a ticket quickly. California only allows non-reflective blackout in the top four inches of the front windshield and front side windows, and the shroud must allow at least 70% of the light to pass through. If you are arrested for an offense, the first offense is a fairly minor matter. The police will cite you with a “fix it” fine, requiring that you make the glass meet the requirements within a specified period and pay a nominal fine of $ 25. However, if you do not comply with this initial citation, the second stop it could cost up to $ 200.

Michigan

In the Great Lakes state, the northern sun can hit your eyes in summer. But you will have to invest in a pair of polarized sunglasses if you want to block it out completely. Like almost all states, Michigan does not place restrictions on the level of shading a driver can have on the rear and rear side panels, but it also does not enforce its standard as a percentage of sunlight that can be allowed through. On both the front windshield and the front side windows, a driver can only have one strip of coverage for the top four inches. This makes the law much easier to enforce, since officers do not have to guess how much light is allowed through. Earlier this year, an interstate drug dealer was arrested after taking a trip from Wisconsin, where a 50% standard is used, and was immediately taken into custody. Michigan makes an exception for people with medical needs who are more sensitive than normal to light.

New Mexico

The land of enchantment is also the land of scorching desert heat. In summers, days can go into triple digits for weeks. In that heat, cars sitting in the sun can turn into ovens. Understandably, then, New Mexico has the least restrictive window tint regulations in the country. On all sides except the front, the driver’s panels only need to let in 20% sunlight, essentially at the level of the limo.
