What the Idaho Transportation Department actually tests

Idaho does not score road signs as a separate test. The knowledge test itself is 40 questions and you need 34 right to pass.

The full detail, quoted from the Idaho Driver's Handbook and ITD testing guide, is on the Idaho license guide. The official source is the Idaho Transportation Department.

Practice by topic

Idaho does not score signs separately, and the state says third-party practice tests do not represent its exam. Use the handbook and ITD’s samples for the exam itself, and use the practice here to drill signs and road rules.
