How to get a window tint medical exemption in Washington

Washington grants an exemption from its tint limits on a qualifying medical certification. There is no state form — Washington State Patrol - there is nothing to file; the physician's letter in the glovebox is the exemption. No fee is published.

The steps

  1. 1

    Get written verification from a licensed physician that you need protection from sunlight for a physical or medical reason. The statute is worded around the operator or a passenger, so a passenger's condition qualifies the vehicle.

  2. 2

    Do not look for a form. The State Patrol states plainly that no form exists to complete or submit for a window tint exemption, which is why calls to the agency go nowhere.

  3. 3

    Keep the physician's letter in the vehicle at all times and hand it over if an officer asks. That is the whole mechanism.

  4. 4

    Remember what the exemption does not change: tint still needs both side mirrors giving a 200 foot view to the rear, and commercial vehicles follow federal rules instead.
