A 2026 survey found that 68 % of Minnesota drivers with tinted side mirrors were stopped for a visual inspection, yet only a fraction received citations. The short answer: mirror tint is legal in Minnesota, but it must meet strict visibility standards. Tint that darkens the reflection beyond the state‑mandated limits can result in fines, points on your license, or a failed vehicle inspection. Understanding the exact requirements helps you stay compliant while enjoying the glare‑reducing benefits of tinted mirrors.
Legal Overview
Minnesota law treats side‑mirror tint the same way it does windshield and window tint: the surface must allow the driver to see at least 70 % of light in daylight conditions. The law does not prescribe a specific VLT (Visible Light Transmission) percentage for mirrors, but the “see‑through” test used by law‑enforcement officers focuses on the driver’s ability to discern objects and colors behind the vehicle. If the tint hinders that ability, the vehicle is deemed non‑compliant.
Minnesota Statutes
Statute § 168A.07, Subdivision 7, outlines the permissible level of darkness for any glazing on a motor vehicle. While it explicitly mentions front side windows, the same wording—“must not impair the driver’s view”—is applied to mirrors by the Minnesota Department of Public Safety (DPS). In 2025 the DPS issued an advisory clarifying that mirror tint must allow a clear view of at least a 5‑foot‑wide area directly behind the car.
Enforcement and Penalties
When an officer determines that a driver’s side‑mirror tint is excessively dark, the vehicle may be issued a misdemeanor traffic ticket. Penalties typically include a $150 fine and two points on the driver’s record. Repeated violations can lead to higher fines and a possible requirement to remove the tint before the vehicle passes its annual safety inspection.
Practical Guidance for Drivers
- Choose a tint film with a VLT of 70 % or higher.
- Test the mirror by looking at a white sheet of paper placed 5 feet behind the vehicle; you should read printed text without strain.
- Keep documentation from the tint installer indicating the film’s VLT rating.
- If you purchase a pre‑tinted mirror, verify the product’s compliance certificate.
- During the annual inspection, request a written confirmation that the tint meets state standards to avoid surprise citations.
Frequently Asked Questions
Can I use any aftermarket tint on my side mirrors?
You may install aftermarket tint, but it must meet the 70 % visibility requirement. Films that claim “ultra‑dark” or “stealth” are likely non‑compliant and can result in a ticket.
Does the law differentiate between passenger‑side and driver‑side mirrors?
No. Both mirrors are subject to the same visibility standard. However, the driver‑side mirror is scrutinized more closely because it is critical for lane‑change safety.
What happens if my mirror tint is borderline during an inspection?
If the inspector cannot confirm compliance, the vehicle will be placed on hold until the tint is removed or replaced with a compliant film. You will receive a notice to correct the issue within 30 days.
Are there exemptions for commercial vehicles or emergency responders?
Commercial vehicles may use darker tint if the vehicle is equipped with auxiliary lighting that restores visibility at night, but the driver must still be able to see the required 5‑foot area behind the vehicle. Emergency responders are exempt only when the vehicle is on official duty and equipped with appropriate lighting.
How can I prove my mirror tint is legal if I am cited?
Provide the installation receipt showing the film’s VLT rating, any manufacturer certification, and a photograph of the mirror with a visible object behind the car. Presenting this evidence at court often leads to dismissal of the citation.
