The summary below reflects the Montana Vehicle Code and DMV publications as of 2026-05. Tint laws change and enforcement varies by jurisdiction. Always verify with the Montana DMV or a local tint installer before installing — penalties for over-dark tint range from fix-it tickets to fines and mandatory removal.

Lower VLT = darker tint. "Any" means the state does not restrict VLT on that window.

Penalty for over-dark tint in Montana
Misdemeanor; fines up to $500. Most Montana tint enforcement happens during routine traffic stops — police can request a VLT reading on the side glass with a handheld meter.
Practical advice: stay one step above the legal limit if you can. A 35% film on fronts in a 35% state can read slightly under at the meter due to existing factory tint in the glass — running 40–50% leaves headroom.
Medical exemption in Montana
Montana allows a medical exemption for darker tint with documentation from a licensed physician. Conditions that commonly qualify include lupus, photosensitive disorders, melanoma history, and certain eye conditions. Process and required forms are available from the Montana DMV. Allow 2–6 weeks for processing.
