If I have a signed letter by my doctor indicating a medical necessity for tinted windows can another person drive my vehicle if the windows are tinted?
MCL 257.709(3)(e) allows for front side window tinting with “…a letter signed by a physician or optometrist, indicating that the special window treatment or application is a medical necessity. However, the special window treatment or application shall not interfere with or obstruct the driver’s clear vision of the highway or an intersecting highway.” A vehicle equipped with such tinting could not legally be driven by a person other than the person to whom the letter was given.
