Ohio's knowledge test is 40 questions and you must answer 75% of them (30) correctly. It is scored as one test, not as separate sections.
Pick an answer on each question to see whether you got it right, with an explanation.
This is a short sample — DriveDrill has 200+ Ohio questions
and full-length mock exams in the app.
Q1. A driver is following you too closely. The safest response is to:
A Turn on your hazard lights and keep speedB Brake sharply to warn themC Speed up to open the gapD Slow gradually and let them pass
Increase your own space cushion and give them a chance to go by. Brake-checking turns their mistake into your crash.
Q2. School zone speed limits usually apply:
A Only on school busesB 24 hours a day, every dayC Only during the first week of schoolD During posted hours or when children are present
Read the sign: many zones are time-based, others use flashing beacons or a when-children-are-present condition.
Q3. In Ohio you must stop at least 10 feet from a school bus with red lights flashing unless:
A The bus is on a hillB You are on a road with four or more lanes and travelling in the opposite directionC You are running lateD Children are already off the bus
On a road of four or more lanes, only traffic behind the bus must stop. On roads with fewer lanes, both directions stop.
Q4. You are being passed by a large truck. You should:
A Stay to the right of your lane and let it passB Speed up so it takes less timeC Brake hard to help it inD Move left toward the center line
Hold a steady speed and keep right within your lane. Air turbulence can push a small car, so keep both hands on the wheel.
Q5. Ohio's Digest of Motor Vehicle Laws recommends keeping a following distance of at least:
A One vehicle length for every 10 mph, or four secondsB Ten secondsC One secondD Two car lengths at any speed
Increase the gap in bad weather and behind motorcycles and large trucks.
Q6. A strong crosswind is pushing your vehicle. You should:
A Slow down and keep a firm grip with both handsB Steer with one hand and relaxC Drive closer to large trucks for shelterD Speed up to stabilise the car
Wind gusts are strongest in open country and beside large vehicles. Slow down, hold the wheel firmly, and expect a push when a truck passes.
Q7. An Ohio driver aged 16 with a probationary license may not drive between:
A 9 p.m. and 5 a.m.B 10 p.m. and 5 a.m. under any circumstancesC Midnight and 6 a.m. unless with a parent or guardian, or for work with documentationD 11 p.m. and 6 a.m. on weekends
At 17 the window narrows to 1 a.m. to 5 a.m., and the restriction ends at 18.
Q8. An exit number on a green sign tells you:
A The distance to the next cityB How many lanes the ramp hasC The speed limit on the rampD Which exit to take for a destination or route
Exit numbers usually match the nearest mile marker, which makes it easy to judge how far away your exit still is.
Q9. A flashing yellow arrow at a left-turn lane means:
A You have a protected left turnB You may turn left after yielding to oncoming traffic and pedestriansC Stop and wait for a green arrowD Left turns are prohibited
A flashing yellow arrow is an unprotected turn. Oncoming traffic has the green, so you may only go when there is a safe gap.
Q10. In Ohio, if an adult in the front seat is not wearing a seat belt:
A An officer may ticket you only after stopping you for something elseB The rule applies only on interstate highwaysC An officer may stop you for the seat belt violation aloneD Seat belts are recommended but not required for adults
This is a secondary enforcement state, so the belt alone is not grounds for the stop. That is a rule about enforcement, not about safety -- the crash risk is the same, and the ticket still follows any other stop.
