Iowa compared with bordering jurisdictions
Tint is enforced where you are stopped, not where it was installed, so a legal install at home can be a ticket one line over. These are the jurisdictions sharing a land border with Iowa.

How to read these numbers
Three details trip up more drivers than the percentages themselves. First, the limit applies to the combined reading of glass plus film, and factory glass is never perfectly clear, so a film's box rating always overstates what a meter will read on the car. Second, the windshield is its own category everywhere: below the AS-1 line (the small marking near the top corner of the glass), meaningful tint is illegal across both countries, whatever the side windows allow. Third, reflectivity is regulated separately from darkness, and mirrored or metallic film fails in most jurisdictions even at a legal VLT.

Iowa tint law questions, answered
What is the legal tint limit in Iowa?
Front side windows: 50% (lowered from 70% effective July 1, 2026). Back side windows: Any darkness. Rear window: Any darkness. Where a figure is given it is a minimum VLT, meaning the share of light that must still pass through the glass and film together, so a higher number requires a lighter film.
Is 5% limo tint legal in Iowa?
Not on the front side windows: Iowa requires them to pass at least 50% of light, and 5% film blocks far more than that. Behind the driver the answer flips: Iowa sets no darkness floor on the back side or rear windows, so 5% limo film is fine there, subject to the mirror and vehicle-type conditions noted in the table.
What is the darkest legal tint in Iowa?
The darkest legal film on the front side windows in Iowa is 50% VLT under the headline figure; the full front-side rule above has the details. Of the shades shops commonly stock, 70% and 50% pass there, while 35%, 20% and 5% do not. Behind the driver there is no floor at all, so the darkest film available is legal on the back side and rear glass. A lower VLT number is a darker window.
Is a medical exemption for darker tint available in Iowa?
No. Iowa has no medical exemption process, so a physician's letter does not authorize film darker than the standard limit.
What does Iowa allow on the windshield?
Entire windshield must keep 70%+ transmittance. The windshield is regulated separately from side glass everywhere in North America, so whatever shade is legal on the doors says nothing about what is permitted up front.
Is Iowa stricter than other states on window tint?
Iowa requires 50% (lowered from 70% effective July 1, 2026) on the front side windows. Of the jurisdictions that publish a numeric limit, 8 require a lighter film than that and 35 allow darker. The same front-side figure applies in Minnesota, Ohio, Virginia, Wisconsin.
Is there anything unusual about the Iowa rule?
HF 766 (2026) cut the front-side minimum to 50%. Medical exemptions were abolished in 2012.
