Limo owners often wonder if the sleek, dark windows that give their ride a premium look are allowed on New Mexico roads. The short answer for 2026 is yes, provided the tint meets the state’s specific Visible Light Transmission (VLT) limits and complies with commercial‑vehicle exemptions. Anything darker than the legal threshold can trigger a traffic stop, a citation, and costly re‑tinting. Understanding those limits—and how they differ for limousines versus personal cars—keeps you cruising legally and avoids unexpected fines.
State Tint Limits for Passenger Vehicles
New Mexico law caps window tint on passenger cars at 35 percent VLT for the front side windows and at least 20 percent VLT for the rear side and back windows (NMSA 1978, § 66‑3‑6). The windshield may only have a non‑reflective strip at the very top. A limousine that is classified as a passenger vehicle must follow these same percentages unless it qualifies under the commercial‑vehicle exemption.
Special Rules for Limousines and Commercial Vehicles
Limousines used for hire are treated as commercial vehicles. Under NMSA 1978, § 66‑3‑8, commercial‑purpose vehicles may tint the rear side and back windows to as low as 5 percent VLT, but the front side windows still cannot fall below 35 percent VLT. The driver’s side front window may be darker only if the vehicle is registered as a “Limousine‑Class A” with the Motor Vehicle Division and a tint‑certificate is on file.
Enforcement and Penalties
Police officers use a handheld photometer to measure VLT during traffic stops. If the tint exceeds legal limits, drivers receive a citation that carries a base fine of $150 plus court costs. Repeat offenses can lead to a $300 fine and mandatory removal of the illegal tint. Commercial‑vehicle violations may also trigger a suspension of the vehicle’s commercial registration until compliance is proven.
Ensuring Your Tint Meets the Law
- Purchase tint from a certified installer who provides a written VLT rating.
- Keep the installer’s receipt and the tint‑certificate in the glove compartment.
- If you own a limousine, register it under the appropriate commercial class and submit the tint documentation to the Motor Vehicle Division.
- Periodically re‑check VLT with a certified meter, especially after repairs or replacements.
Frequently Asked Questions
Can I apply a darker tint to my limousine’s front windows if I only use it for personal events?
No. Even when used privately, a limousine is still classified as a passenger vehicle, so the front side windows must stay at 35 percent VLT or higher.
Are aftermarket tint kits legal for limousines?
Only if the kit’s VLT rating matches the statutory limits and the installation is performed by a licensed professional who supplies documentation.
What happens if I’m stopped and the officer can’t measure VLT on the spot?
The officer may issue a “show cause” notice, giving you 15 days to present a certified VLT report at the court. Failure to comply results in the standard citation and fine.
Do windshield tints count toward the VLT limits?
No. New Mexico permits a non‑reflective strip at the top of the windshield, but any tint covering the main viewing area is prohibited.
Is there a grace period for newly purchased limousines with existing tint?
There is no statutory grace period. All vehicles must comply at the time of registration; otherwise, a citation is issued immediately.
