Before you get any permit or license, Illinois checks that you can see well enough to drive. It also treats cheating on the exam as a serious offense.

Know the rule

Every driver's license applicant must pass a vision screening or submit a Vision Specialist Report from a licensed optometrist, ophthalmologist or physician, dated within six months of the facility visit.
