The steps

  1. 1

    Have a Connecticut-licensed physician or optometrist examine you and write a recommendation. An examination is required; a letter written without one does not satisfy the regulation.

  2. 2

    Apply in writing to the DMV Commissioner, attaching the recommendation. You sign the application under penalty of false statement.

  3. 3

    Take the vehicle to the Wethersfield inspection lane. The DMV validates the request after the vehicle passes tint measurement there, so the sequence is apply, then measure, then validate.

  4. 4

    Expect a referral to the Medical Review Unit as part of the process.

  5. 5

    Keep the validated form in the exempted vehicle. The exemption covers vehicles you own, lease or regularly ride in, which is broader than most states.

  6. 6

    Do not plan on going below 20 percent. The regulation treats that as impairing driving safety even under an exemption, and the waiver for good cause is discretionary.

Which conditions qualify

Connecticut publishes no list of named conditions. The test is whether a qualifying provider certifies that you require shielding from the direct rays of the sun.

What gets refused

  • Tint dark enough to impair driving safety. The regulation deems anything below 20 percent light transmittance to impair it, though the Commissioner may waive that for good cause
