Connecticut Window Tint Laws 2026
Connecticut requires 35% VLT on front side windows, back side windows, and the rearmost window on a passenger car, the back side windows and rear window are governed by the same clause with the same numbers, no unrestricted rear window for a sedan. Trucks, buses, trailers, mobile homes, and multipurpose vehicles, the SUV category, get a genuinely different rule: no light transmittance limit at all on the windows behind the driver, as long as the vehicle has outside mirrors on both sides that see at least 200 feet to the rear.
Two things worth getting right: The reflectivity limits are often reported backwards, front is 27%, back is 21%, not the reverse. And a sedan's rear window is not unrestricted, it shares the same 35% standard as the back side windows. The real unlimited-darkness allowance belongs to trucks, buses, and SUVs, not passenger cars.
Quick Reference
| Window | Passenger Car | Truck / Bus / MPV |
|---|---|---|
| Windshield | Non-reflective strip, top of windshield, AS-1 line | |
| Front side windows / wing vents | 35%, 27% reflectance | 35%, 27% reflectance |
| Back side windows | 35%, 21% reflectance | No limit, dual mirrors req'd |
| Rearmost window | 35%, 21% reflectance | No limit, dual mirrors req'd |
One Rule for Back Side and Rear Windows, Not Two
Conn. Gen. Stat. 14-99g(c) sets the standard in two groups. Front side windows and front side wing vents need a light transmission of not less than 35%, plus or minus 3%, and a reflectance of no more than 27%, plus or minus 3%. Separately, "the right and left side windows behind the driver and the rearmost window" are covered together in their own clause, not less than 35% transmission and no more than 21% reflectance, plus or minus 3% on both.
That single combined clause is the important part for sedans. Several competitor pages describe Connecticut as giving a sedan an unrestricted rear window while holding the back side windows to 35%, an asymmetric rule that doesn't actually appear in the statute. For a passenger car, the rear window and the back side windows are the same provision with the same numbers.
Trucks, Buses, and SUVs Get a Real Exemption, Just Not Sedans
Connecticut does have a genuine unlimited-darkness allowance, it just doesn't apply to passenger cars. A separate clause in 14-99g(c) exempts the windows behind the driver on any truck, motor bus, trailer, mobile manufactured home, or multipurpose passenger vehicle, the federal classification that covers most SUVs, from the light transmittance and reflectance standards entirely. The condition attached is real too: the vehicle has to be equipped with outside mirrors on the left and right-hand sides positioned so the driver can see the highway for at least 200 feet to the rear.
The reason SUVs and trucks get this treatment traces back to federal glazing standards, not a state policy choice. Under 49 CFR 571.3 and FMVSS 205, a multipurpose passenger vehicle's glazing has to conform to truck requirements rather than passenger car requirements, so Connecticut's tint statute follows that same federal vehicle classification.
The Reflectivity Numbers Are Often Reported Backwards
This is worth calling out directly because it's a genuinely common error. The front side windows carry the higher reflectance allowance, 27%. The back side windows and rear window carry the lower one, 21%. Multiple tint guides list these numbers swapped, 21% for the front and 27% for the back, which is the reverse of what the statute actually says.
Legal vs Illegal
Legal
- ✓35%+ VLT film on front side windows, up to 27% reflectance, any vehicle
- ✓35%+ VLT on sedan back side and rear windows, up to 21% reflectance
- ✓Any darkness behind the driver on a truck, bus, or SUV with mirrors on both sides
- ✓DMV-approved compliance sticker properly placed
Illegal
- ✕Any window below 35% VLT without exemption
- ✕Front reflectance above 27%, or back/rear reflectance above 21% on a passenger car
- ✕Mirror-like tint finish on any window
- ✕Tinted windows without the required DMV-approved sticker
The Compliance Sticker System
Connecticut requires a DMV-approved sticker on tinted windows, and this isn't a loose, optional label. The commissioner won't approve a tinted material or its sticker for sale in the state unless the manufacturer demonstrates the product actually complies with the transmission and reflectance standards in the statute. The sticker itself comes with written placement instructions that installers are required to follow when delivering tinted material for installation.
Medical Exemptions
Who the exemption covers
A person who requires shielding from the direct rays of the sun for medical reasons is exempt from the standard requirements. That exemption extends beyond just a vehicle that person personally drives, it also covers a vehicle belonging to them, or one in which they are a usual passenger, so a family member can drive a vehicle tinted for someone else's medical need without losing the exemption's protection.
Enforcement
Tint is a primary offense in Connecticut. State Police and local departments can stop a vehicle based on tint appearance alone, checking both the VLT reading and the reflectance level against the front or back standard depending on which window is in question.
What Legal Tint Actually Costs in Connecticut
Since every covered window on a passenger car, front and back alike, shares the same 35% VLT floor, most sedan installs in Connecticut run a fairly uniform film across the vehicle rather than a sharp clear-front, dark-rear contrast. Truck and SUV owners have real freedom on the rear glass once dual mirrors are confirmed in place. Ceramic film is a common upgrade for UV and infrared rejection at any given VLT.
| Film Type | Sedan | SUV / Truck |
|---|---|---|
| Dyed film | $140 to $260 | $200 to $370 |
| Carbon film | $200 to $320 | $260 to $410 |
| Ceramic film | $230 to $440 | $320 to $590 |
