About the Iowa Written Knowledge Test

The Iowa written knowledge test is administered by the Iowa DOT. To obtain your Instruction Permit, you must be at least 14 years old and score at least 80% on a 35-question multiple-choice exam. Questions cover road signs, right-of-way rules, traffic laws, and safe driving practices from the Iowadriver's manual.

Our free practice tests use the same multiple-choice format as the real exam, with instant feedback and explanations for every question. Practice as many times as you need — no signup required.
