(1) For purposes of this section:

(a) "Injury" means a trauma to the integrity or function of a tissue or organ and the resulting physical conditions;

(b) "Illness" means a condition marked by an obvious deviation from the normal healthy state, characterized by sickness, disease, or other disorder. Alcohol abuse, drug abuse, antisocial behavior, or criminal history alone, or your commitment to a treatment facility, is insufficient by itself to show "illness" within the meaning of this section.

(2) Verification of your injury or illness may, at the department's discretion, require verification from a physician.
