The Iowa permit test is the written knowledge exam required to earn a Iowa learner's permit. Administered by the Iowa DOT, it is based on the official Iowa driver handbook.
The Iowa DOT knowledge test has 25 questions covering traffic laws, road signs, and safe driving from the Iowa Driver's Manual. You must answer at least 80% (20 of 25) correctly to pass, plus a vision test.
The instruction permit must be held for at least 12 months before the driving test for an intermediate license at 16.
In Iowa, new drivers typically begin with a learner's permit at 14 years old, required, and log 20 hours (2 at night) of supervised driving over a 12 months permit hold before earning a provisional license. The Iowa DOT administers the knowledge test, permits, and driver's licenses statewide.
