Four rounds of 10 questions on Ohio road signs, right-of-way, speed limits, parking, OVI and phone laws, and teen rules. Every answer comes with a quick explanation.
On a two-lane country road in Ohio you come up behind a tractor. Fixed to its rear is an orange triangle with a red reflective border. What does that emblem tell you?
Correct answer: The vehicle travels slower than 25 mph
Why
That triangle is the slow-moving vehicle emblem. In Ohio it marks farm machinery, construction equipment and horse-drawn buggies that move at under 25 mph, so you will close the gap quickly. Ease off early; you may cross a solid yellow line to get around one only if it's going under half the posted limit, the oncoming lane is clear and you stay within the limit yourself.
You're stopped at a red light in downtown Columbus and want to turn left. When does Ohio allow a left turn on red after a full stop?
Correct answer: Only when the street you're on and the street you're turning onto both carry one-way traffic, with no sign against it
Why
Ohio lets you turn left on red in just one case: you're in the far-left lane of a one-way street, turning onto a street where traffic also runs one way, after a complete stop and with no sign prohibiting it. Right turns on red are allowed more widely, also after a full stop and while yielding to crossing traffic and pedestrians. Check for a NO TURN ON RED sign before either turn.
Ohio's basic speed law sets a limit you must follow whatever number is posted. What is it?
Correct answer: Keep your speed low enough to halt inside the stretch of open road you can see in front of you
Why
Ohio law calls it the assured clear distance ahead: your speed must let you stop within the stretch of road you can see is clear, and it must suit traffic and road conditions. In fog, snow or on a dark curve, that can mean driving well under the sign. If you couldn't stop in the space you see, you're going too fast.
You spot an open curb space near a fire hydrant. How close to the hydrant does Ohio law let you park?
Correct answer: No closer than 10 feet
Why
Ohio bans standing or parking within 10 feet of a fire hydrant. Fire crews need clear access to hook up a hose fast, so give more room when you can. Pair this number with two others: 20 feet from an intersection crosswalk and 30 feet from a stop sign.
A 20-year-old had one beer at a cookout and is stopped on the drive home. A breath test reads 0.03%. Under Ohio law, what's the situation?
Correct answer: A violation, because the limit for drivers under 21 is 0.02%
Why
Ohio sets a 0.02% limit for drivers under 21; the offense is called OVUAC, operating a vehicle after underage alcohol consumption. At 0.08% the adult OVI law applies, and commercial drivers are held to 0.04%. An underage conviction can bring a suspension of 3 months to 2 years.
How much following distance does the Ohio Driver Manual recommend behind the car ahead?
Correct answer: At least four seconds
Why
Pick a fixed point such as a sign; when the car ahead passes it, start counting. If you reach the point before four seconds, back off. Ohio's manual also gives a rule of thumb of one car length for every 10 mph, and asks for more room at night, in bad weather, on slick roads and behind large vehicles.
What's the earliest age at which you can take the Ohio knowledge test and get a temporary instruction permit (TIPIC)?
Correct answer: 15 years and 6 months
Why
Ohio lets you take the vision screening and knowledge test at 15 years and 6 months. After you pass, you have 60 days to buy the TIPIC at a Deputy Registrar License Agency, and a parent or guardian co-signs if you're under 18. The permit is good for one year.
A yellow diamond sign reads ONE LANE BRIDGE, and a pickup is heading toward the same bridge from the far side. According to the Ohio Driver Manual, which vehicle may cross first?
Correct answer: The one nearest the bridge
Why
Only one vehicle fits on the bridge at a time, and Ohio gives the right-of-way to whoever is closer to it. If the pickup will reach it before you, slow down, stop short of the entrance and wait until it has cleared. Speeding up to claim the bridge only sets up a head-on standoff.
A school bus stops on a two-lane road to let children off. Its red lights flash and the stop arm swings out. Under Ohio law, who has to stop?
Correct answer: Drivers from both directions, staying at least 10 feet back
Why
On a road with fewer than four lanes, traffic from both directions must halt 10 or more feet away and wait until the bus moves or its driver waves them on. Only on highways with four or more lanes may drivers coming the other way keep going; drivers behind the bus always stop. Flashing amber lights mean the bus is about to stop, and passing it illegally can cost up to $500 and a license suspension.
Your car breaks down on a rural Ohio highway after dark. You've steered onto the shoulder and turned on your flashers. If you carry flares, where should they go?
Correct answer: About 200 to 300 feet behind the car
Why
Flares set 200 to 300 feet back give approaching drivers time to spot trouble and change lanes before they reach you. Get the car as far off the road as you can and keep the hazard flashers on. Stay clear of passing traffic while you place them.
In Ohio, which kind of road can carry a SPEED LIMIT 70 sign like this one?
Correct answer: A rural freeway, such as an interstate through open country
Why
70 mph is the top speed limit anywhere in Ohio, and only rural freeways get it. Rural expressways without signals top out at 65 mph, and freeways in urban areas usually run 55 or 65. Whatever the sign says, slow down when traffic or weather calls for it.
Orange signs, cones and barrels mark a work zone on an Ohio highway, but you don't see anyone working. What does the Ohio Driver Manual expect from you?
Correct answer: Slow down anyway, since speeding there can double your fine and even lead to jail
Why
Orange is the color of work zones, and the hazards stay even when the crew is out of sight: lane shifts, rough pavement, equipment parked close to traffic. Speeding in an Ohio work zone can cost double the normal fine, and jail time is possible. Obey any flagger, keep extra space and watch for workers stepping out.
You and another driver pull up to a four-way stop at the same moment. The other car is on the street to your right. Who goes first?
Correct answer: The driver on your right
Why
When two vehicles arrive together, Ohio has you yield to the one on your right; otherwise, the first to arrive is the first to go. Make eye contact and wait for a clear sign the other driver is moving before you pull out. A wave is a courtesy, not a promise.
On the approach to a stop sign, how far back must your parked car be in Ohio?
Correct answer: At least 30 feet
Why
Ohio keeps parked cars at least 30 feet back from a stop sign, a yield sign or a traffic signal on the approach side. A car parked closer would hide the sign and cross traffic from other drivers. Railroad crossings need even more room: 50 feet from the nearest rail.
Arrested for OVI for the first time, a driver refuses to take a breath, blood or urine test. What happens to the license?
Correct answer: An immediate administrative suspension of one year
Why
Driving in Ohio means you've already agreed to chemical testing if you're arrested for OVI. A first refusal brings an on-the-spot administrative suspension of one year, and it stands even if you're later found not guilty. Testing over the limit on a first offense, by comparison, brings a 90-day administrative suspension.
It's midday, a steady rain is falling and your windshield wipers are running. What does Ohio law say about your headlights?
Correct answer: They must be on whenever rain or snow has your wipers going
Why
Ohio ties headlights to wipers: if precipitation has your wipers on, your headlights must be on too. They're also required from sunset to sunrise and whenever you can't see people and vehicles 1,000 feet ahead. Parking lights alone don't count at any of those times.
You're 16 and a half with a TIPIC. Who may sit beside you as your supervising driver?
Correct answer: Any licensed driver who is 21 or older
Why
From age 16, Ohio lets a permit holder practice with any licensed driver aged 21+ sitting next to them. Before 16, the list narrows to a parent, guardian or custodian, a licensed driving instructor, or an adult 21+ acting in place of a parent. Your supervisor must be sober, and everyone in the car buckles up.
A double solid yellow line runs down the middle of your two-lane road. When does Ohio allow you to cross it?
Correct answer: To turn left into a driveway, or to pass a slow-moving vehicle such as a bicycle when it's safe
Why
A double solid yellow line bans passing from both directions. Ohio still lets you cross it to turn left into a driveway, or to get around a slow-moving vehicle, such as a bicycle or one with the orange triangle, when the oncoming lane is clear. A car that's simply a little slow doesn't qualify.
You turn onto a residential street inside an Ohio city and haven't passed a speed limit sign. What limit applies?
Correct answer: 25 mph
Why
Unless signs say otherwise, Ohio sets 25 mph on streets inside a city or village. Alleys drop to 15 mph, while state routes running through town outside business districts rise to 35 mph. On a neighborhood street with no sign in sight, 25 is the number to remember.
Before the driving test, how much supervised practice must an Ohio driver under 21 log on top of driver education?
Correct answer: 50 hours, at least 10 of them at night
Why
Ohio requires 50 hours behind the wheel with a supervising driver, including at least 10 after dark. You record them on the notarized BMV 5791 Fifty-Hour Affidavit and bring it to your driving test. The RoadReady Ohio app can track the hours for you.
Past a round yellow sign marked with an X and the letters RR, you reach a crossing where the red lights are flashing. Under Ohio law, where should your car come to a stop?
Correct answer: No closer than 15 feet and no farther than 50 feet from the nearest rail
Why
The round yellow sign is your early warning; the white X-shaped crossbuck marks the tracks themselves. When signals flash, a gate is lowered or a train is near, Ohio requires you to stop within 50 feet of the nearest rail but not closer than 15 feet. Never drive around or under a gate that is down or moving.
The side street you're on meets a busier road, and a red-and-white triangle pointing downward stands at the corner. In which situation does it require a full stop?
Correct answer: Only when other traffic is close enough that you'd get in its way
Why
That's a YIELD sign. Slow down and check both ways; if the road is clear you may keep rolling, but anyone near enough to be affected goes first. The Ohio Driver Manual adds that you yield to all oncoming traffic, so be ready to stop rather than squeeze in.
On a divided highway with a grass median, an ambulance with lights and siren is racing along the opposite side. What should you do?
Correct answer: Keep driving with care, since you don't have to pull over for it
Why
Ohio’s pull-right-and-stop rule covers emergency vehicles coming from either direction, with one exception: a vehicle traveling the opposite way on a divided highway. An ambulance across the median can’t reach your lanes, so stopping would only create a new hazard. If one comes up behind you, though, move right, stop and wait until it passes.
Which of these parking spots is legal in Ohio?
Correct answer: 25 feet from a fire station driveway, on the same side of the street
Why
Near a fire station, Ohio's rule is 20 feet from the driveway, or 75 feet across the street where signs are posted, so 25 feet on the same side is fine. The other spots all break the law: hydrants need 10 feet, intersection crosswalks 20 feet and railroad crossings 50 feet, measured from the closest rail.
Under Ohio's hands-free law, which of these may an adult driver do while driving?
Correct answer: Answer a call with one tap on a mounted phone and talk hands-free
Why
Ohio law bars holding, supporting or using a phone while you drive, with a few exceptions. Adults may talk hands-free, start a call with a single tap or swipe, or hold the phone to an ear during a call, but they can’t type. Calling emergency services is always allowed, and a first offense can cost up to $150 and 2 points.
Even where no sign prohibits it, when is a U-turn against Ohio law?
Correct answer: On a curve or near a hilltop where other drivers couldn't see you from 500 feet away
Why
A U-turn leaves you crosswise in the road, so Ohio bans it on a curve, or close to a hilltop or on the climb toward one, whenever drivers coming from either direction couldn't see you within 500 feet. Choose a spot with a long clear view both ways, or go around the block. Where a sign shows a U-turn arrow in a red circle with a slash, don't turn at all.
You're 16 with a TIPIC. Unless a licensed parent, guardian or custodian rides with you, during which hours can't you drive?
Correct answer: Midnight to 6 a.m.
Why
Permit holders under 18 may not drive between midnight and 6 a.m. unless a parent, guardian or custodian with a valid Ohio license sits beside them. The 1 to 5 a.m. window comes later, for probationary drivers past their first year. Plan practice drives so you're home before midnight.
On a highway with two lanes in your direction, you're approaching a police car stopped on the right shoulder with its lights flashing. What does Ohio's Move Over law tell you to do?
Correct answer: Move to the lane away from the police car if you safely can; if not, slow down and pass with caution
Why
Ohio's Move Over law covers stopped police and emergency vehicles, tow trucks, highway maintenance and waste collection trucks with flashing lights. Shift over a lane when traffic allows; if you can't, slow down and stay alert as you pass. Breaking this law costs twice the usual fine.
When does Ohio's 20 mph school zone limit apply?
Correct answer: During school recess and while children are arriving or leaving, where 20 mph school signs are posted
Why
Ohio's school zone limit is 20 mph during recess and while children are going to or leaving school, wherever the 20 mph school signs are up. State law doesn't require flashing lights to mark those times, so don't wait for a beacon to slow down. Watch for kids stepping out between parked cars.
During the first 12 months with an Ohio probationary license, how many passengers who aren't family members may you carry without a parent, guardian or custodian in the car?
Correct answer: One
Why
For the first year, Ohio limits a probationary driver to one non-family passenger unless a parent, guardian or custodian is along. Every rider also needs a seat belt of their own, and everyone buckles up. Fewer friends in the car means fewer distractions while you build experience.
A yellow diamond sign with three arrows chasing each other in a circle warns that a roundabout is ahead. When you reach it, who has the right-of-way?
Correct answer: Vehicles already circling inside the roundabout
Why
Traffic in a roundabout flows counterclockwise, and drivers coming in yield to vehicles already circulating. Wait for a gap, enter to the right and keep moving. Once you're inside, don't stop or switch lanes until you're about to exit.
Where are you most likely to find a red circle crossed by a white horizontal bar with the words DO NOT ENTER?
Correct answer: Where a one-way road meets another street, and at freeway exit ramps
Why
DO NOT ENTER guards roads where all traffic comes toward you: the wrong end of a one-way street and the bottom of a freeway exit ramp. If you realize you've passed one, pull over where it's safe and turn around. At highway speed, a wrong turn onto a ramp can mean a head-on crash.
Any Ohio sign that shows a black symbol inside a red circle with a red diagonal slash across it is telling you what?
Correct answer: The action shown is not allowed
Why
The Ohio Driver Manual calls these prohibitory signs: the red circle and slash simply mean NO. The symbol inside tells you what's banned, such as a U-turn or a left turn. Read the symbol first and the meaning follows.
When you parallel park on an Ohio street, what is the farthest your wheels may be from the curb?
Correct answer: 12 inches
Why
Ohio's manual has you park parallel to the curb, facing the same way as traffic, with your wheels no more than 12 inches away. On a one-way street you may use either curb. Park too far out and you squeeze the lane for everyone passing.
You're 17 and drive with a probationary license. Which use of your phone is allowed while you're driving?
Correct answer: Calling 911 to report an emergency
Why
Ohio bars drivers under 18 from using a phone or other wireless device in any way, even hands-free and even while stopped in traffic. The exceptions are emergencies, being parked out of the travel lane, and navigation used hands-free. A first violation means a $150 fine and a 60-day suspension.
Your friend in the passenger seat wants to open a can of beer while you drive on an Ohio highway. What does state law say?
Correct answer: It's banned, because the law covers the driver and every passenger
Why
Ohio's open container law applies to everyone riding in a motor vehicle on a public road or in a parking area, not only the driver. The exceptions are narrow, such as a passenger in a hired limousine. If you're carrying alcohol, keep it sealed and out of reach, ideally in the trunk.
At night, an oncoming car's bright headlights are making it hard for you to see. Where should you look?
Correct answer: Toward the right edge of the road
Why
Glancing toward the right edge of the road keeps you on course without taking the full glare. Don't answer with your own high beams; Ohio has you dim them for oncoming traffic. Tinted lenses at night only make things darker.
You plan to turn right into a parking lot ahead. Under Ohio law, when should your turn signal be on?
Correct answer: Steadily through the final 100 feet, or more, leading up to the turn
Why
Ohio wants your signal blinking without a break over the final 100 feet or more before you turn or shift right or left, and the same goes for lane changes. You also signal before stopping or slowing suddenly. Hand signals are legal too, which helps if a bulb burns out.
You're 19 and applying for your first Ohio license. Since September 30, 2025, what do you need before the driving test?
Correct answer: Driver education and 50 hours of supervised practice, but no six-month permit wait
Why
Ohio now requires drivers aged 18, 19 and 20 to finish driver training, 24 hours of class plus 8 hours with an instructor, and to log 50 supervised hours. Unlike younger teens, they don’t have to hold the permit for six months first. Most first-time drivers 21 and older need training only if they fail their first driving test.
The middle lane of a busy road has a pair of yellow lines along each edge, one solid and one dashed, and white turn arrows inside it point opposite ways. How may you use it?
Correct answer: Only to make a left turn, from either direction
Why
You’re looking at a lane shared by left-turning drivers from both directions. Signal, move into it just before your turn, and wait there for a gap. Ohio’s manual says never to use it for passing or as a lane to drive along.

Ohio · BMV knowledge test
75% to pass.
40 questions · Multiple choice30 of 40 answers right to pass
18 to 20? Since September 30, 2025, you need driver ed and 50 practice hours too, but no six-month wait. At 21 or older, most new drivers just get a permit and pass the driving test.
Study the Ohio Driver Manual, also called the Digest of Ohio Motor Vehicle Laws (HSY 7607, edition 10/25). Sections 2 through 10 cover the signs and Ohio laws the test asks about. Here’s what to know cold in six key areas.
Six Ohio figures worth knowing by heart before test day.
These 40 questions are just the warm-up. The app gives you 486 Ohio practice questions, 36 short lessons and the why behind every answer.
40 multiple-choice questions on traffic signs and Ohio motor vehicle laws, given by the Bureau of Motor Vehicles (BMV), Ohio’s version of the DMV. You need 75% to pass, which means at least 30 right. You’ll also need to pass a vision screening before your permit is issued.
In person there’s no limit: after a fail, wait 24 hours and try again, at most once a day. Online you get two attempts in any six-month period, at least 24 hours apart, and after that you test in person.
Yes. Through BMV Online Services you can test on a computer or laptop with a working webcam (not a phone or tablet), and anyone under 19 needs a supervising adult who passes an identity check. You can also test at a Driver Exam Station or a select Deputy Registrar License Agency. After an online pass, the Deputy Registrar does your vision screening when you buy the permit.
Yes. The BMV gives the knowledge test in Spanish as both text and audio, alongside Arabic, Chinese, French, Haitian Creole, Japanese, Russian, Somali and English, plus American Sign Language. The Ohio Driver Manual has no Spanish edition, so this practice test and the app, both in Spanish, make studying easier.
15½. Under 18, you hold the TIPIC at least six months, finish driver ed and log 50 supervised hours, 10 at night, before a probationary license at 16. In the first year, no driving midnight–6 a.m. (unless a parent or guardian rides along or you carry papers for work, school or a religious event) and no more than one non-family passenger without a parent or guardian; after that and until 18, no driving 1–5 a.m. Phones are off-limits the whole time, even hands-free, except for emergencies and hands-free navigation.
The TIPIC costs $26.50, Deputy Registrar fee included. Buy it within 60 days of passing the knowledge test and vision screening, or you’ll have to start over. If you get your first license at 16, it costs $28.75.
Two parts: a maneuverability test, where you steer forward through a 9-by-20-foot box of markers and then back out, and an on-road drive with an examiner. Knocking down or running over a marker fails you on the spot. You book it through BMV Online Services. If you’re under 21, bring your Fifty-Hour Affidavit, and if you don’t pass, you can retest after two days.
Read Sections 2 through 10 of the Ohio Driver Manual, then practice until 75% feels easy. Start with the 40 questions above, then let the app walk you through 486 Ohio questions and 36 short lessons, with an explanation for every answer.
