Ohio DMV is administered by the Ohio Bureau of Motor Vehicles (BMV), headquartered in Columbus. The official Ohio written knowledge exam has 40 questions, and drivers must answer 30 correctly (75%) to pass. Our practice tests match the exact format, topics, and difficulty of the real Ohio DMV test.
What makes the Ohio DMV test unique?
Ohio's 40-question exam is split into a 20-question road-rules and a 20-question road-signs section — you must score at least 15 of 20 (75%) on each.
Ohio's distracted-driving law became a primary offense in 2023 — officers can stop drivers for handling a device alone.
Study road signs as its own independent section — a weak sign score alone can fail you.
