Ohio Tint Laws: Legal Window Tint Limits by Window

Last verified: October 29, 2026 against ORC 4513.241 (effective April 9, 2025) and OAC Chapter 4501-41

Ohio tint laws set different limits for different windows, so there is no single legal tint percentage for the whole car. The number that matters is visible light transmission, or VLT: the share of light that passes through the glass. A lower number means a darker window.

This page explains what tint is legal in Ohio for your windshield, front doors and back windows, how the law treats reflective film, who can get a medical exemption, and what a ticket looks like.

Ohio tint laws by window: what is the legal tint?

Ohio sets the legal tint by window position: 70% for the windshield, 50% for the front side windows, and no minimum for the windows behind the driver. The Ohio Department of Public Safety wrote these limits into OAC 4501-41-03 under authority from ORC 4513.241.

Window	Legal VLT in Ohio	Other limits
Windshield	70% or more (plus or minus 3%)	Not red or yellow. Top strip allowed down to the AS-1 line or 5 inches.
Front driver and passenger windows	50% or more (plus or minus 3%)	Not red or yellow. No reflective film.
Rear side windows	Any darkness	No set minimum. No reflective film. The mirror rule is tied to the rear window.
Rear window	Any darkness	Same mirror rule. No reflective film.

The rule applies to motor vehicles that must be registered in Ohio. The text does not split passenger cars from SUVs, vans or trucks, so the same percentages apply to all of them.

What is the darkest legal tint in Ohio?

The darkest legal tint depends on the window: 50% on the front doors, 70% on the windshield, and as dark as you like on the back half of the vehicle.

The rear windows have no darkness limit, so a 5% film (often called limo tint) is legal there. The catch is the mirror rule. If the rear window lets through less than 50% of light, the car must have outside rear-view mirrors on both the left and right sides.

Is 35 window tint legal in Ohio?

A 35% film is legal on the rear side windows and rear window, but not on the front side windows or the windshield.

On the front doors, Ohio requires 50% light transmission with a 3% tolerance. A 35% film is darker than that minimum, so it will not pass a meter reading. The same logic answers the common questions about 20% and 5% tint: both are fine in back and both are too dark up front.

Is 5 tint legal in Ohio?

Yes on the rear side windows and rear window, and no on the front side windows or windshield.

A very dark film in back is allowed as long as your outside mirrors are in place. Windshield readings include the glass itself, so a film that looks light can still fail once it is on the window.

How dark can front side windows be in Ohio?

Front side windows must let at least 50% of light through, with a 3% tolerance (OAC 4501-41-03).

That means a reading of 47% or higher on an officer meter can still meet the rule, because of the 3% tolerance. The film also cannot be red or yellow. Factory tint that meets federal standard FMVSS 205 is allowed even if it is darker than the aftermarket limit.

Windshield tint and the AS-1 line

Ohio allows a darkened strip across the top of the windshield, down to the AS-1 line or 5 inches from the top, whichever is closer to the top.

The AS-1 line is a small marking printed on most windshields near the top corner. Below that line, any added film must keep at least 70% light transmission and cannot be red or yellow. Sun-shade strips, visor bands and eyebrow tint are the usual products that fit this exception.

Reflective and mirror tint

Reflective tint is banned on the windshield, the side windows, the sidewings and the rear window (ORC 4513.241).

Metallic or mirror-finish films can pass a darkness reading and still be illegal because they are reflectorized. Check the label before you buy. Film makers must label each product with the manufacturer name and the light transmission percentage, and they must warn buyers that film that drops a window below 70% may violate federal law (OAC 4501-41-04).

Medical exemption for darker tint

Ohio lets you run darker tint if a doctor says you need it, but you must keep the paperwork in the car.

The vehicle must be registered to the patient or to the patient’s parent, legal guardian or spouse. The affidavit must come from an Ohio-licensed physician or optometrist and state that a physical condition makes the tint necessary. The driver must carry it at all times (OAC 4501-41-05). Chauffeured limousines and hearses are also exempt for the windows behind the driver (OAC 4501-41-05).

What happens if you are ticketed for illegal tint?

Driving a vehicle with illegal tint is a minor misdemeanor, which carries a fine of up to $150 and no jail time (ORC 4513.241, ORC 2929.28).

Violation	Level	Penalty (maximum)
Driving, leasing or renting a nonconforming vehicle	Minor misdemeanor	$150 fine, no jail
Dealer selling a nonconforming vehicle (knowing)	Minor misdemeanor	$150 fine, no jail
Installing nonconforming film or glass	Fourth-degree misdemeanor	Up to 30 days in jail and a $250 fine
Repeat installer who is a licensed dealer or registered repair operator	Same as above	Registration or license suspension of up to 180 days

Ranges come from ORC 2929.24 and ORC 2929.28. A court can set a lower fine, and court costs are added. Installers can also be sued by the vehicle owner for damages and attorney fees.

Real Ohio scenarios

• Buying a used SUV in Columbus. The back glass is dark from the factory. That is fine under the FMVSS 205 exception, but film added to the front doors by a prior owner still has to meet 50%.
• Moving from another state. Once you register the car in Ohio, the Ohio limits apply. A front-door film that was legal where you lived may now be too dark.
• A 20% film on all windows. The back windows pass. The front doors and windshield do not, so you could be pulled over and cited for those two.
• Sun-sensitive condition. A driver whose doctor provides a signed affidavit may run darker front tint, as long as the affidavit stays in the car.

Myths and facts

Myth	Fact
“Ohio has one legal tint percentage.”	Ohio has separate limits: 70% windshield, 50% front sides, none for back windows.
“5% tint is illegal everywhere on the car.”	It is allowed on rear side windows and the rear window if you have both outside mirrors.
“A 3% tolerance means 35% front tint is fine.”	The tolerance is a small margin around 50%. A 35% film is far below that.
“Tint shops handle the legal risk.”	The driver can still be cited, and shops that install nonconforming film face their own penalties.

Columbus, Cleveland and other city rules

Tint limits come from state law, so Columbus, Cleveland, Cincinnati and other Ohio cities enforce the same percentages. A city police officer or an Ohio State Highway Patrol trooper can cite you under the state rule.

Tint can give an officer a reason to pull you over. Our Driving and Vehicles section covers other Ohio traffic rules, including the booster seat and car seat rules for children in your car.

What to do if you are cited

• Read the ticket for the section cited, the court date and whether you must appear in person.
• Take the film off the front windows or replace it with a compliant film, then keep proof of the repair.
• If you have a medical need, bring the physician or optometrist affidavit to court.
• You may plead not guilty and ask the court to review the meter reading and the officer’s method.

Frequently asked questions

What is the legal tint in Ohio?

Ohio requires at least 70% light transmission on the windshield and 50% on the front side windows, each with a 3% tolerance. Rear side windows and the rear window can be any darkness if the car has left and right outside mirrors (OAC 4501-41-03).

What percent tint is legal in Ohio for front windows?

The front driver and passenger windows must allow at least 50% of light through. With the 3% tolerance, a reading of 47% can still pass. Red, yellow and reflective films are not allowed on those windows.

Is 20 tint legal in Ohio?

Only on the rear side windows and the rear window. A 20% film is darker than the 50% minimum for front side windows and the 70% minimum for the windshield, so a front or windshield application can get you a ticket.

Does Ohio require side mirrors with dark rear tint?

Yes. If the rear window lets through less than 50% of light, the vehicle must have outside rear-view mirrors on both the left and right sides. With both mirrors, rear windows can be as dark as you choose.

Can I get a medical exemption for darker tint?

Yes. You need an affidavit from an Ohio-licensed physician or optometrist saying a physical condition makes the tint necessary. The vehicle must be registered to you or your parent, guardian or spouse, and the affidavit must stay in the vehicle (OAC 4501-41-05).

How much is a window tint ticket in Ohio?

Illegal tint is a minor misdemeanor for the driver, with a fine of up to $150 plus court costs and no jail time. A person who installs nonconforming film commits a fourth-degree misdemeanor, with up to 30 days in jail and a $250 fine.

Is mirror or reflective tint legal in Ohio?

No. Reflectorized material is banned on the windshield, side windows, sidewings and rear window under ORC 4513.241. A film can meet the darkness limit and still be illegal if it is reflective, so check the product label.
