Idaho DMV is administered by the Idaho Transportation Department (ITD), headquartered in Boise. The official Idaho written knowledge exam has 40 questions, and drivers must answer 34 correctly (85%) to pass. Our practice tests match the exact format, topics, and difficulty of the real Idaho DMV test.
What makes the Idaho DMV test unique?
Idaho has one of the highest passing thresholds in the country at 85% — only 6 mistakes allowed out of 40.
Idaho's "Stop as Yield" law allows cyclists to treat stop signs as yield signs and red lights as stop signs — unique among US states.
With the 85% passing threshold, plan to score at least 90% on practice tests before attempting the real exam.
