The short answer: In Vermont, as of 2026 a driver may legally tint the front side windows of a passenger vehicle to no more than 35 percent VLT (Visible Light Transmission), while the rear side windows and back glass may be darkened to any degree. This rule applies to all passenger cars, SUVs, and light trucks, and is enforced by both state police and local law enforcement. Violations can result in a fine of up to $500 and a requirement to remove the illegal tint within 30 days.
How Vermont’s Tint Regulations Are Structured
Vermont’s vehicle code (Title 10, Chapter 413) sets distinct limits for different window locations. The front side windows (driver’s side and passenger’s side) must allow at least 35 percent of outside light to pass through. The front windshield may have a non‑reflective tint of no more than 20 percent VLT, primarily for glare reduction. For the rear side windows and rear window, the statute imposes no minimum VLT, meaning drivers may install any darkness they prefer, provided the tint does not impair visibility for other road users.
The law distinguishes between factory‑installed tint and after‑market applications. If a vehicle leaves the factory with a tint that meets the front‑window threshold, it is considered compliant even if the manufacturer used a slightly different measurement method. After‑market tint must be installed by a certified technician and accompanied by a tint compliance sticker displayed on the driver’s side door jamb.
Enforcement and Penalties
Police officers use a handheld tint meter to verify VLT percentages during traffic stops or routine inspections. If a vehicle fails the test, the driver receives a civil citation and must either pay the fine or appear in court. Re‑tinting the vehicle to meet legal standards is required within 30 days; failure to do so may lead to additional penalties, including the possibility of vehicle registration suspension.
Law‑enforcement agencies also conduct random compliance checks during summer months when dark tint is most popular. The state encourages drivers to keep their tint documentation handy to avoid unnecessary delays during stops.
Frequently Asked Questions
What is the difference between VLT and “shade” numbers?
VLT (Visible Light Transmission) is the percentage of light that passes through the glass; a lower percentage means a darker tint. “Shade” numbers, often seen in the aftermarket industry, are a nominal rating that does not directly correspond to VLT and can be misleading. Vermont law requires compliance based on VLT, not shade rating.
Can I have a darker tint on my windshield for glare protection?
Yes, Vermont permits a non‑reflective tint on the windshield up to 20 percent VLT. The tint must be applied only to the top 5 inches of the glass and cannot be reflective.
Does the law apply to commercial vehicles and vans?
The same front‑window VLT limit of 35 percent applies to all light‑weight vehicles, including commercial vans and trucks. However, larger commercial trucks may have different standards under federal regulations, so drivers should consult the specific vehicle classification.
Are there exemptions for medical reasons?
Vermont allows a medical exemption for drivers who require additional tint due to a diagnosed condition such as photosensitivity. The driver must obtain a physician’s certification and submit it to the Department of Motor Vehicles to receive a special permit.
How can I verify that my tint meets legal requirements before installation?
Most reputable tint shops use calibrated tint meters that provide an accurate VLT reading. Ask the installer to show you the measurement and request a compliance sticker for the driver’s side door jamb after the job is completed. This documentation helps avoid future citations.
