Iowa Written Knowledge Test
Who Must Take the Knowledge Test?
- You must take the knowledge test if you have not had a learner’s permit or full driver’s license before.
- You must also take the test when required to get an Iowa license and your out-of-state license is invalid or expired (over one year).
- Applicants with an out-of-country license are usually required to take all tests.
- Tests are also required when your license has been revoked and you apply for a new license.
When moving to Iowa you must apply for an Iowa license. If you have an out-of-state license valid for the same driving privilege you are applying for in Iowa, the knowledge and driving tests are usually waived.
The Purpose of the Written Test
The purpose of the official knowledge exam is to verify how well you know and understand highway signs and Iowa traffic laws.
Iowa DOT offers computer-based tests for both permits and driver’s licenses. A traditional written test on paper may still be available in some locations.
While the number of questions on the tests may vary, the test a new learner’s permit has 35 questions. 20 questions address traffic laws and safe driving techniques. Remaining 15 questions are about signs, signals, and markings.
