Tint laws by state
Ohio tint laws: 50% on the front doors, free behind
Ohio measures the film with the glass and allows 3 points either way. Enter both: the calculator checks the front doors against 50% and shows the rest of the car as free.

Ohio regulates the front of the car and leaves the back to the owner. Under Ohio Rev. Code § 4513.241 and Administrative Code rule 4501-41-03, the side windows to the immediate right and left of the driver must keep a light transmittance of at least 50%, plus or minus 3%, film and glass together, and the film may not be red or yellow. Behind the driver, any darkness is allowed; once the back window falls below 50%, the car needs outside rear-view mirrors on both sides. The windshield is treated in two parts: material along the top that stays above the AS-1 line or within 5 inches of the top, whichever is closer to the top, is not regulated, and below that the windshield must keep 70%, plus or minus 3. Reflective materials are banned everywhere. Because the glass counts, a 50% film fails on most front doors: on 75% glass it reads 37.5%. Operating a car with non-conforming tint is a minor misdemeanor with a fine of up to $150.

The front doors are the whole question
Ohio writes "fifty per cent plus or minus three per cent" for the side windows beside the driver, so the meter must show 47% or more. Factory glass already removes part of the light before any film goes on, so the film has to be lighter than the number on the law. The table shows common films on two typical glass readings:
| Film | On 75% glass | On 85% glass | Ohio front doors |
|---|---|---|---|
| 80% | 60% | 68% | legal |
| 70% | 52.5% | 59.5% | legal |
| 60% | 45% | 51% | within the margin on 85%, too dark on 75% |
| 50% | 37.5% | 42.5% | too dark |
| 35% | 26.2% | 29.8% | too dark |
Behind the driver
For any other window, the rule allows any light transmittance. The condition is on the mirrors: a back window below 50%, plus or minus 3, requires outside rear-view mirrors on the left and the right. Almost every car sold today has both, so the condition mostly matters for older or modified vehicles. Red and yellow film and reflective finishes stay banned on every window.
The windshield strip, measured
Ohio lets a strip run along the top as long as it stays above the AS-1 line or within 5 inches of the top, whichever is closer to the top. Below that limit the windshield must keep 70%, plus or minus 3, with the glass. Enter the depth of your strip to see where it lands in Ohio or in any other state:

Exemptions
A medical need is handled by affidavit, not by permit: an Ohio-licensed physician or optometrist signs it, and it stays in the vehicle whenever the person is aboard. The rule on exemptions also covers some vehicle types listed in rule 4501-41-05; check the text before relying on one of them.
Penalty and how the rules are kept current
Operating a car with non-conforming tint is a minor misdemeanor; the general misdemeanor rule caps the fine at $150. Installing it is a fourth-degree misdemeanor. Section 4513.241 was last rewritten with effect from April 9, 2025, and the administrative rule dates from 2014, with its next review due in 2031.
Around Ohio
Michigan allows no film on the front side windows, Pennsylvania asks for 70% in its inspection table, Indiana for 30%, Kentucky for 35% and West Virginia for 35%. An Ohio car with a 70% film on the front doors passes on the front in Indiana, Kentucky and West Virginia, but Pennsylvania's table asks for 70% with the glass and Michigan allows only a top strip there.
