Vermont Window Tint Laws Explained: Legal VLT Limits for 2026

Vermont surprises people who assume every state just publishes a VLT percentage and calls it a day. The blunt reality is that you can’t legally add aftermarket tint to the windshield or the front side windows at all — there is no allowed VLT for film on the front side glass. The statute is a flat prohibition, not a darkness limit, with a narrow medical exemption as the main exception.

How dark can you legally tint in Vermont?

On the front, you effectively can’t. Under 23 V.S.A. § 1125, a person may not operate a vehicle with material painted or adhered on or over any transparent part of the windshield, vent windows, or the side windows immediately left and right of the driver — with only small corner sticker spaces and a few specific items allowed. The same text is on Justia’s Vermont code. Because it’s a prohibition, there’s no “legal percentage” for front film.

Where Vermont drivers go wrong

Wrong: “Vermont allows tint as long as it’s above some percentage.” The reality is the front isn’t governed by a percentage at all. The statute prohibits adhered material over the windshield and front side windows outright, so a 70% film up front is still a violation unless you hold a medical exemption.

Wrong: “Dark rear glass is automatically fine.” The reality is the rear side windows and back glass are allowed to be obstructed only if the vehicle has a securely attached mirror on each side. No dual mirrors, no dark rear glass. The mirrors are the condition, not a suggestion.

The medical exemption and the windshield rule

Vermont’s medical exemption is genuine: the Commissioner of Motor Vehicles may grant it on application with a document signed by a licensed physician or optometrist certifying that shielding from the sun is a medical necessity, and it’s renewed every four years. But it’s narrow — the shading it allows is limited to the vent or front side windows, and the exemption ends when the vehicle is sold, at which point the seller must remove the film. The windshield itself is reserved for clear glass aside from small corner spaces, consistent with the driver-vision purpose behind the federal glazing standard, FMVSS 205 (49 CFR 571.205). A revised § 1125 is scheduled to take effect July 1, 2026 — proposed, not yet in effect — so the prohibition above is what governs today.

Penalties and what you must keep

Tint that violates § 1125 is enforced as a traffic violation, and the realistic cost is a stop, a fine, and the removal of film that was never allowed up front. If you carry a medical exemption, keep the approval where you can produce it, and remember the film must be removed before you sell the car. Worn film that tears, bubbles, or blocks clear vision has to be removed or replaced even under the exemption.

What to do: If you want a darker daily, keep the front glass clear, run privacy film on the rear only with dual mirrors in place, and pursue the medical exemption through the DMV if a doctor certifies the need. Don’t install front film on the assumption that a percentage makes it legal.

Vermont’s rules feel tight, but they’re also easy to follow once you know front film is off the table: keep the windshield and front doors clear, run privacy film in back with mirrors, and use the medical route if a doctor certifies it.

If heat and UV are the real concern and front darkness isn’t an option where you drive, a clear heat-rejecting film plus ceramic coating or paint protection film does a lot of the work — and you can compare neighbors on our New Hampshire and Maine guides.
