Vision is so important that Iowa requires that you pass a vision screening before you get a driver’s license or permit, or when you renew your license. This screening is to make sure you have at least 20/40 vision in at least one eye, with or without corrective lenses
Driver Knowledge Test
The knowledge test shows how well you know and understand highway signs and Iowa traffic laws. Each copy of the test tells you the number of questions you must answer correctly to pass the test. Iowa's larger driver's license stations offer a computer-based electronic way to complete the
knowledge exam. If you renew your license within 60 days of its expiration, you probably will not have to take the knowledge test again.
Road Driving Test
The driving test shows how well you can control your vehicle. Unless you can already legally drive in Iowa, you will need to have a licensed driver bring you and your test vehicle to the test site.
