Who reads the tint statutes behind Tint Law Check
Radif Partners
Independent publisher of state-by-state window tint limits and vehicle equipment rules for the United States, with a combined tint calculator
Tint Law Check is published by Radif Partners, a company that builds free calculators on public data. This one is for drivers who want darker windows without a ticket, for people who just bought a used car with film already on it, and for anyone moving to another state with a tinted car.
What the site does
A film is sold by its own percentage, while an officer's meter reads the film and the glass together. The calculator multiplies the two, as the meter does, and compares each window with the minimum written in your state's statute, its tolerance and its separate rule for SUVs and vans. It also gives the darkest film your glass can take, so you know what to ask for before you buy.
Where the limits come from
For each of the 50 states and the District of Columbia we read the vehicle code section on window tint, 102 sections and rules in all, on the legislature's official site whenever it answered, and kept a word-for-word extract of the sentence that gives each figure. When an official site refused our connection, the page says which copy of the law we read and when. A figure we could not find in the law is shown as missing, never guessed. The method page explains each step.
What we are not
We are not a police agency, a DMV, a court or a law firm, and nothing here is legal advice. We do not sell film, do not install it and do not send anyone to a tint shop. We use no state seal or logo.
How the site is paid for
It is free and asks for no account and no email. We take no commission from film makers, installers or lawyers. If advertising is added one day, it will never sit above the calculator, and it cannot see what you enter, because nothing you type leaves your browser.
