What Is the Darkest Legal Tint in Texas?

Here's exactly how dark you can go on each window in Texas — and how a medical exemption lets you go even darker.

Quick Answer

Under Texas Transportation Code §547.613, the darkest legal tint without a medical exemption is 25% VLT on front side windows. Back side windows and the rear window can be any darknesson all vehicle types — sedans, SUVs, trucks, and vans.

Medical documentation:§547.613(e) describes a medical-reason defense to prosecution. A signed statement is not a blanket promise that every darker tint is lawful, so confirm current DPS guidance and installation requirements.

Darkest Legal Tint by Window in Texas

Front Windshield

25% VLT, non-reflective tint only

The windshield has the strictest rules. Only non-reflective tint is allowed above the manufacturer’s AS-1 line (typically the top 4-5 inches). Full windshield tint is not permitted even with a medical exemption.

Front Side Windows (Driver & Passenger)

25% VLT

This is the only window restriction that matters for most Texas drivers. 25% VLT means at least 25% of outside light must pass through — a medium-dark tint. This is checked during both traffic stops and other current compliance requirements.

Back Side Windows

Any darkness (all vehicle types)

Texas is one of the most permissive states for rear tint. ALL vehicles — sedans, SUVs, trucks, vans — can have any darkness on back side windows. No restrictions, no exemption needed.

Rear Window

Any darkness (all vehicle types)

Same as back side windows — any darkness is legal on all vehicle types. If the rear window is tinted, dual side mirrors are required.

Why the 25% Front Limit Matters in Texas

Texas is unique because the front side windows are the only restricted windows. But that 25% limit is actively enforced in two ways:

Traffic stops — DPS State Troopers, HPD, DPD, SAPD, and all local agencies can pull you over solely for dark front tint

Most non-commercial safety inspections ended January 1, 2025; tint law and roadside enforcement still apply

Enforcement hotspots: I-10/I-45 in Harris County, I-35W in DFW, I-10/I-35 in San Antonio, I-35 in Austin

For drivers with lupus, melanoma history, photophobia, or other UV-sensitive conditions, 25% VLT on the front may not provide adequate protection — especially in El Paso (UV index 11-12, 297 sunny days), Houston (UV 9-10), or Dallas (UV 10-11).

What Do Different VLT Levels Look Like?

Dark tint (needs exemption for front)

Limo tint (needs exemption for front)

Lower VLT = darker tint. Back and rear windows have no limit in Texas. Only front side windows are restricted to 25%.

Want Darker Front Tint? Get a Texas Medical Exemption

If 25% VLT on the front isn't dark enough for your medical needs, a medical exemption under §547.613(e) allows you to legally go darker. This is especially critical for Texas drivers with conditions worsened by the state's extreme UV environment.

Common conditions: lupus (elevated in TX's large Hispanic/Latino population), melanoma (MD Anderson Cancer Center in Houston treats thousands annually), migraines (TX heat is a primary trigger), multiple sclerosis (heat worsens symptoms), photophobia, and TBI-related light sensitivity (common in TX military veteran communities at Fort Cavazos, Fort Bliss, Lackland AFB).

What Happens If Your Front Tint Is Too Dark?

Texas tint violations are Class C misdemeanors

Fine: Up to $200 first offense; $200–$250 repeat offenses
Criminal record: Class C misdemeanor appears on your record
compliance issues: Blocks vehicle registration renewal
Mandatory removal: Court may order tint removal with proof required

A medical exemption at $250 is priced independently from possible citation costs and resolves both enforcement issues (traffic stops and other current compliance requirements) permanently.
