In Iowa, you must pass the official DOT Permit Test to get your license. The test is based on the official Iowa Driver’s Manual (Iowa Driver’s Manual) and uses the same multiple-choice format as the real DOT exam.

The Iowa DOT written test has 25 multiple-choice questions. To pass, you need at least 20 correct (80%).

This is our second Iowa Permit Practice Test, current for May 2026 and based on the official Iowa Driver’s Manual. Each question has four answer options – click the best one. Optional hints can help with tougher questions (the real DOT test has no hints).

If you miss a question, read the explanation carefully so you don’t make the same mistake on the real test. Take the practice test multiple times to enhance your knowledge – questions will be randomized each time.
