The legal tint limit for every window position in North Dakota (35% on the front sides), checked against your own film's VLT, with the medical exemption and what a ticket costs.
North Dakota window tint checker
VLT (visible light transmission) is the share of light the film lets through; a lower number is darker. It is printed on the film packaging or your installation receipt. Leave it blank to just read the limits.
Enter your film's VLT above to check it against each North Dakota window limit, or read the limits as they stand.
Windows behind the driver can be any darkness only when the vehicle carries outside mirrors on both sides (N.D.C.C. §39-21-39(4)). Without dual mirrors, those windows fall back to the 35% floor.
Film is sold by its own VLT, but police measure the installed darkness: the film combined with your factory glass, which reads darker than the film alone. These are the North Dakota figures stated as information, not a determination about any stop or ticket.
Informational only, not legal advice. Reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. See the full rules, the exemption steps, and the citations on the North Dakota window tint reference, cited to N.D.C.C. §39-21-39(4)–(5).
How the North Dakota tint rules work
North Dakota changed its front-window rule in 2025. HB1340 dropped the front side floor from 50% to 35%, so the front doors, back side windows, and rear window now share one 35% number, and the windshield still has to let through 70% apart from a strip at the top. There is a catch worth knowing: windows behind the driver can be any darkness, but only if the car has outside mirrors on both sides. Without dual mirrors, everything back there returns to 35%.
This checker applies the North Dakota figures to the VLT you enter. It is informational only and not legal advice: reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. For the full rules, the shades table, and the citations, see the North Dakota window tint reference, cited to N.D.C.C. §39-21-39(4)–(5).
