People tint their windows for many reasons. Some like the sleek look that it has. Others like the benefits it brings of sun and heat protection and glare reduction. Whether you like one or all benefits of window tinting, there are state laws that regulate them. The laws regulate tinting darkness for two primary reasons. First, its harder to see at night when your windows are dark. This increases risk for drivers in both the windshield and their blind spot. It also allows others to see into the front of the vehicle when approaching. This is for the safety of police officers and the comfort of others approaching the vehicle. Most new vehicles come with some form of tinting to protect against UV rays and for the aesthetic value. However, owners have their vehicle’s tinting modified to darken the color or change the type of tinting. Vehicles sold with tinting are within industry regulations. The tinting afterwards needs to be with these regulations as well. It’s important to find an installer who is aware of these. Window tinting can be more than the color of the glass. It includes:
The tinted sheet of film adhered to the glass
“Shade bands”, which are the thin strip of tinting along the top of the windshield
Temporary sunscreen devices, like those stuck to the window to block sun in a specific spot, regardless of location.
State laws Each state has their own laws. If your windows are legal in one state, it doesn’t mean they will be legal in another. Check with each state’s Department of Motor Vehicles. Arizona, for example, has restrictions on darkness and reflection. The darkness is only regulated on the windshield and side front windows. The back seat windows and rear windows are not regulated. The front windshield is only allowed above the manufacturer’s AS-1 line. The front side windows must allow more than 33% of light in. The front side and back side windows must not be more than 35% reflective. Arizona also restricts using amber or amber tint colors. In nearby Nevada, the darkness laws are identical but they have no reflective laws. California requires 70% of light to be let in and tint may only be used on the top four inches of the windshield. Reflective tint may not be more reflective than regular windows in back side and rear windows. The prohibit the use of red color in tinting. Exemptions There are a few medical exemptions for drivers or passengers with a valid medical or vision impairment condition. The impairment must limit the amount of sun exposure. These may include
certain eye conditions like permanent dilation.
Not all states allow exemptions. Again, check with your state’s Department of Motor Vehicles to determine if you qualify for one. Each state is different. Make sure you check with each state if you’ll be registering your vehicle there. Also, finding a reputable installer who is familiar with your state’s laws.
