Missouri Window Tint Laws Explained: Legal VLT Limits for 2026

Missouri’s window tint laws haven’t kept pace with what drivers actually want. The regulations, defined under Missouri Revised Statutes §307.173, set specific visible light transmission (VLT) percentages for each window on your vehicle — and the limits vary depending on whether you’re driving a sedan or an SUV/truck.

What VLT Percentages Does Missouri Allow?

VLT — visible light transmission — measures how much sunlight passes through your tint film. A lower number means a darker tint. Missouri law treats sedans and larger vehicles differently, which gives SUV and truck owners significantly more flexibility.

Missouri Tint Reflection Rules

Missouri law restricts how reflective your tint can be. Metallic or mirrored finishes that create excessive glare are prohibited. For sedans, front and rear side windows must not be more than 35% reflective. SUVs and trucks follow the same standard — no more than 35% reflective on any side window.

Do You Need a Medical Exemption in Missouri?

Yes, Missouri offers medical exemptions for drivers who need darker tint due to a qualifying medical condition. Conditions like lupus, photosensitivity, or severe skin disorders may qualify. You’ll need a signed statement from a licensed physician specifying the medical necessity, and you must carry this documentation in the vehicle at all times. The exemption allows tint darker than the standard limits on windows that would otherwise be restricted.

Missouri Tint Penalties and Enforcement

Getting caught with illegal tint in Missouri results in a traffic infraction. First-time offenders typically face fines between $75 and $200, though exact amounts vary by jurisdiction. Some counties enforce tint laws more aggressively during routine traffic stops, while others focus on tint only as a secondary offense. Repeat violations can lead to higher fines and orders to remove the non-compliant film. Missouri doesn’t assign points to your license for tint violations, but the financial penalty and removal costs add up quickly.

How Missouri Compares to Neighboring States

Missouri’s 35% front side window limit sits in the middle of the pack compared to its neighbors. Kansas allows 35% on front sides as well, while Illinois requires 35% on front sides but is stricter on sedans overall. Iowa is more restrictive at 70% for front side windows. If you regularly cross state lines, you’ll want to check the laws in each state you travel through — being legal in Missouri doesn’t guarantee compliance elsewhere.

Can You Get Factory Tint in Missouri?

Factory tint — the tinting applied during vehicle manufacturing — is common on rear windows of SUVs and trucks. In Missouri, factory tint is generally compliant because manufacturers design it to meet federal and state regulations. However, if you add aftermarket tint on top of factory tint, the combined VLT must still meet Missouri’s minimum requirements for each window position.
