How to Get a Window Tint Exemption (Medical or Special Use)

A window tint exemption allows darker-than-legal tint for medical conditions (e.g., light sensitivity) or special uses (e.g., law enforcement). To qualify, submit a doctor's certification or agency approval, pay required fees, and follow state-specific application steps. Exemptions may require periodic renewal.

Who Qualifies for a Tint Exemption?

  • Medical conditions: Lupus, melanoma, porphyria, or severe photosensitivity (doctor's note required).
  • Government/law enforcement: Authorized vehicles for undercover or security purposes.
  • Commercial uses: Limousines, hearses, or armored vehicles (varies by state).
  • Disabilities: Some states allow exemptions for mobility-related modifications.

Step-by-Step Application Process

  1. Get documentation:
    • Medical: Signed letter from a licensed physician (on letterhead) stating the condition and need for tint.
    • Non-medical: Agency or employer authorization (e.g., police department).
  2. Check tint limits: Exemptions often allow 20-35% VLT (visible light transmission), but verify local rules.
  3. Complete forms: Download the exemption application from the DMV or relevant agency's website.
  4. Submit and pay: Mail or upload documents with fees (typically $20-$100).
  5. Receive approval: Wait 2-6 weeks for a certificate or sticker (must be displayed in the vehicle).
  6. Renew as needed: Medical exemptions may require annual recertification.

Comparison of Tint Exemption Types

Exemption Type Required Documentation Typical Tint Allowance Processing Time Cost Renewal Required?
Medical Physician's signed letter 20-35% VLT 4-6 weeks $20-$50 Every 1-2 years
Law Enforcement Agency authorization No limit (varies) 2-4 weeks $0-$25 Annually or per assignment
Commercial (Limos/Armored) Business license + vehicle registration 15-20% VLT 3-5 weeks $50-$100 Every 2-3 years

Key Rules to Avoid Rejection

  • Tint limits still apply: Exemptions don't permit 0% VLT (completely opaque) tint.
  • Front windshield restrictions: Most states ban tint below the AS-1 line (top 5-6 inches) even with exemptions.
  • Out-of-state exemptions: Not always honored-check reciprocity rules if traveling.
  • Display proof: Keep the exemption certificate in the vehicle; some states require a visible sticker.
  • No DIY tinting: Professional installation may be required to meet compliance standards.

What Happens If You're Stopped Without an Exemption?

  • First offense: Fine ($50-$250) and order to remove tint.
  • Repeat violations: Higher fines, vehicle inspection failure, or license points.
  • Insurance impact: Illegal tint may void coverage in accident claims.

FAQs About Tint Exemptions

Can I get an exemption for non-medical reasons?

Only if you qualify under government, commercial, or disability categories. Personal preference isn't valid.

How dark can my tint be with an exemption?

Most medical exemptions allow 20-35% VLT (lighter than limo tint). Check your state's exact percentage.

Do exemptions cover all windows?

Usually side and rear windows only. Front windshield and driver/passenger windows often have stricter limits.

Can I apply online?

Some states offer online submissions, but mailed documents (with original signatures) are often required.

Does an exemption override local laws?

No. You must still comply with state-wide tint regulations unless your exemption explicitly overrides them.
