Section 223. Tinted Vehicle Windows.

  (a) No person may drive a motor vehicle upon a highway or a
  vehicular way or area with mirrored tinting material on any window of the
  vehicle. Except as provided in this section, no person may drive a motor
  vehicle upon a highway or a vehicular way or area with aftermarket tinting
  material or aftermarket striping material on any window of the vehicle.

  (b) Aftermarket tinting of vehicle windows is permissible as
  follows:

  (1) the glass immediately in front of the driver may have a
  strip of tinting material applied to the top edge, known in the industry as
  an "eyebrow," which does not extend downward more than five inches from the
  top of the glass;
  (2) the windows immediately to the driver's right and left
  may have tinting material that permits at least 70 percent light
  transmittance;
  (3) the rear door windows, quarter glasses, and back glasses
  may have tinting material that permits at least 40 percent light
  transmittance;
  (4) limousines and passenger buses used to transport persons
  for hire, motor homes, and vehicles identified by the vehicle manufacturer as
  multipurpose may have tinting material that complies with Standard No. 205,
  Glazing materials in 49 C.F.R. 571.205 (1992).

  (c) The windows of a vehicle may have tinting material that
  permits less light transmittance than that specified in (b) of this section
  if

  (1) a driver or a passenger who frequently travels in the
  vehicle is required for medical reasons to be shielded from the direct rays
  of the sun;
  (2) the medical reasons are certified annually by a
  physician licensed to practice in this state; and
  (3) the certification is carried in the vehicle.

  (d) Tinting materials must be green, gray, or neutral smoke in color.

  (e) Light transmittance must be measured by using a light
  transmittance measuring device with an allowance for manufacturing variances
  of plus or minus three percent. The accuracy of the device must be certified
  by the manufaturer of the device.

  (f) In this section, "light transmittance" means the ratio,
  expressed as a percentage, of the amount of total light that is allowed to
  pass through a window, including glazing, to the amount of total light
  falling on the window.

  (g) All vehicles must comply with this section by July 1, 1994.
