Section 1 · Traffic Signs and Signals20 questions
1-1. Sign Shapes, Colors, and Regulatory Signs
★★★★★ 35% (estimate)
Overview
Half of the Ohio knowledge test is about signs and signals, and this chapter starts with the basics: what sign shapes and colors mean and how to read the white and red signs that state rules. Once you know the shape and color system, you can tell what most signs are about before you can read the words.
Shape comes first. The red eight-sided sign is used only for STOP, so you must come to a full stop at it. The red and white triangle pointing down is used only for YIELD, so you slow down, let traffic and people walking go first, and stop if you need to. White rectangles state rules you must obey, such as speed limits, ONE WAY, and lane-use arrows.
Color tells you the job of the sign. Red is used for stop, yield, DO NOT ENTER, and WRONG WAY. White means a rule, green guides you with directions and distances, blue shows services for drivers, and brown leads to parks and recreation. A red circle with a slash over a symbol means the action shown is not allowed.
Some rule signs come with legal details. At a STOP sign with no stop line or crosswalk, Ohio law says to stop where you can see traffic on the cross road before entering it. Where NO TURN ON RED is posted, you must wait for green. A posted speed limit is the top speed in good conditions, and slower drivers must keep to the right-hand lane.
Key notes
- STOP sign
- — A red eight-sided sign (octagon). Come to a complete stop at the stop line, or before the crosswalk, or where you can see cross traffic before entering. Then yield to traffic close enough to be a hazard and go when it is safe.
- YIELD sign
- — A red and white triangle pointing down. Slow down, stop if needed, and let vehicles in the intersection or close enough to be a hazard go first. If you pass it without stopping and hit a vehicle in the intersection, that is evidence you failed to yield.
- Regulatory signs
- — Mostly white rectangles with black or red letters, plus red signs such as STOP, YIELD, DO NOT ENTER, and WRONG WAY. They state rules you must obey, such as speed limits, ONE WAY, and lane-use arrows.
- Sign colors
- — Red: stop, yield, do not enter, wrong way. White: rules. Green: directions and distances. Blue: services for drivers. Brown: parks and recreation. Yellow and orange are used for warnings, covered in the next chapter.
- Red circle with slash
- — On a white regulatory sign, a red circle with a red slash over a symbol means the action shown, such as a left turn or a U-turn, is not allowed.
- NO TURN ON RED
- — Ohio usually allows a right turn on red after a full stop. Local authorities and the state can ban turns on red at an intersection by posting a sign. Then you must wait for a green light.
- Slower traffic keep right
- — A vehicle moving slower than the normal speed of traffic must use the right-hand lane, except when passing, preparing for a left turn, or staying on its route.
★ Exam points
- The octagon is used only for STOP signs.
- The downward triangle is used only for YIELD signs.
- White rectangle signs state rules you must obey.
- A red circle with a slash means the action shown is not allowed.
- An overhead arrow with ONLY means vehicles in that lane must go that way.
- A WRONG WAY sign means turn around safely: traffic is coming toward you.
1-2. Warning, School, and Work Zone Signs
★★★★★ 35% (estimate)
Overview
Warning signs tell you about a hazard or change in the road before you reach it, so you have time to slow down. This chapter covers yellow diamond warning signs, school and pedestrian signs, railroad warning signs, and orange work zone signs.
Most warning signs are yellow diamonds with a black symbol. A plus-shaped symbol means a crossroad ahead, a red octagon above an arrow means a STOP sign ahead, and two arrows pointing opposite ways mean two-way traffic ahead. A yellow plaque with a speed under a warning sign shows the advised safe speed for that curve or hazard.
Some warning signs use other shapes and colors. The five-sided sign marks a school zone or school crossing, and fluorescent yellow-green is used for school, pedestrian, and bicycle warnings. The round yellow sign with an X and two R letters warns of a railroad crossing ahead, and the yellow pennant on the left side of the road marks the start of a no passing zone.
Orange signs mark work zones, where lanes may close and workers may be on the road. Follow every sign and flagger: a STOP paddle means stop, and a SLOW paddle means move ahead slowly and carefully. At a railroad crossing, when a train is close or signals warn of one, stop between 15 and 50 feet from the nearest rail.
Key notes
- Yellow diamond
- — The usual shape and color for warning signs. It warns of a hazard or change ahead, such as a crossroad, a stop sign ahead, two-way traffic, a slippery road, or a lane ending.
- Advisory speed plaque
- — A yellow plaque with a speed, placed under a warning sign. It shows the advised safe speed for the curve or hazard. It is not the speed limit for the whole road.
- School signs
- — The five-sided (pentagon) sign marks a school zone or school crossing. Fluorescent yellow-green is used for school, pedestrian, and bicycle warnings.
- Railroad warning signs
- — The round yellow sign with an X and two R letters warns that a railroad crossing is ahead. The white X-shaped crossbuck marks the crossing itself. When a train is close or signals warn of one, stop within 50 feet but not less than 15 feet from the nearest rail.
- No passing zone pennant
- — A yellow sign shaped like a sideways triangle, placed on the left side of the road. It marks the start of a no passing zone.
- Work zone signs and flaggers
- — Orange signs mark work zones. A flagger's STOP paddle means stop. The SLOW paddle means move ahead slowly and carefully, watching for workers and equipment.
★ Exam points
- Yellow diamond signs warn of hazards or changes ahead.
- A red octagon above an arrow on a yellow sign means a STOP sign is ahead.
- Two arrows pointing opposite ways mean two-way traffic ahead: keep right.
- The five-sided sign means a school zone or school crossing.
- Orange signs mark work zones.
- The yellow pennant on the left side of the road starts a no passing zone.
1-3. Traffic Signals and Pavement Markings
★★★★☆ 30% (estimate)
Overview
Traffic signals and the lines painted on the road control traffic where signs alone are not enough. This chapter covers steady and flashing lights, arrows, signals that are dark, and how to read yellow and white pavement lines.
A steady red light means stop and stay stopped. In Ohio you may still turn right on red after a full stop, or turn left from a one-way street onto another one-way street, unless a sign forbids it or a red arrow is shown. A steady yellow light warns that red is coming, so stop if you safely can. A green arrow lets you make the movement shown, while still yielding to pedestrians and vehicles in the intersection.
Flashing lights have their own meanings. A flashing red light means stop and then go as at a STOP sign. A flashing yellow light means go with caution, and a flashing yellow arrow means you may turn only after yielding to oncoming traffic and pedestrians. If a signal shows no lights at all, Ohio law says to stop, yield, and then go with care, just as at a STOP sign.
Pavement lines finish the picture. Yellow lines separate traffic going in opposite directions, and white lines separate lanes going the same way. A double solid yellow line means no passing either way, while a broken yellow line on your side means you may pass when it is safe. A center lane with solid and broken yellow lines on both sides is a two-way left-turn lane, used only for left turns.
Key notes
- Steady red and turn on red
- — Stop at the stop line, crosswalk, or intersection edge and stay stopped. After a full stop you may turn right, or turn left from a one-way street onto a one-way street, unless a sign forbids it. A steady red arrow means you may not make that turn.
- Steady yellow
- — Warns that the green movement is ending and a red light comes next. Stop if you can do so safely.
- Flashing red and flashing yellow
- — Flashing red: stop, then go as at a STOP sign. Flashing yellow: go through with caution, yielding to pedestrians and vehicles in the intersection. Flashing yellow arrow: turn only after yielding to oncoming traffic and pedestrians.
- Dark signal
- — If a signal shows no lights, or a mix of lights that does not clearly assign the right of way, stop, yield to vehicles in or near the intersection, and go with care.
- Yellow and white lines
- — Yellow lines separate traffic going in opposite directions. White lines separate lanes going in the same direction. A solid white line discourages lane changes, and a broken white line allows them when safe.
- Passing lines
- — Double solid yellow: no passing in either direction. Broken yellow on your side: you may pass when safe. Solid yellow on your side: you may not pass.
- Two-way left-turn lane
- — A center lane with a solid yellow line and a broken yellow line on each side. Drivers from both directions use it only to turn left. It is not a passing or travel lane.
★ Exam points
- A flashing red light means the same as a STOP sign.
- A flashing yellow light means slow down and go with caution.
- A signal with no lights means stop and yield as at a STOP sign.
- Left on red is allowed only from a one-way street onto a one-way street, after a full stop.
- Yellow lines separate opposite directions; white lines separate the same direction.
- A double solid yellow line means no passing in either direction.
Section 2 · Ohio Traffic Laws20 questions
2-1. Right of Way, School Buses, and Emergency Vehicles
★★★★★ 25% (estimate)
Overview
Right of way rules decide who goes first so that drivers do not have to guess. This chapter covers intersections, left turns, driveways, pedestrians, school buses, and emergency vehicles. The law never gives anyone the right to cause a crash, so always be ready to give way.
At an intersection with no signs or signals, when two vehicles arrive at about the same time, the driver on the left yields to the driver on the right. A driver turning left yields to oncoming vehicles that are close enough to be a hazard. A driver entering a road from a driveway, alley, or parking lot yields to all traffic on that road, and in a business or residence district must stop before driving onto the sidewalk area.
Pedestrians need special care. Where there is no working signal, yield to a person crossing in a crosswalk who is on your half of the road or coming so close from the other half as to be in danger. If another vehicle is stopped at a crosswalk to let someone cross, you must not pass it.
For a school bus stopped to load or unload children, stop at least 10 feet from the bus and stay stopped until the bus moves or the driver signals you to go. On a highway with four or more lanes, traffic coming from the opposite direction does not have to stop. For an emergency vehicle using lights and a siren, pull to the right edge clear of any intersection and stop. For stopped vehicles with flashing lights, move over a lane if safe, or slow down.
Key notes
- Same time, no signs
- — When two vehicles approach or enter an intersection from different roads at about the same time, the driver on the left yields to the driver on the right.
- Left turns and driveways
- — A driver turning left yields to oncoming vehicles close enough to be a hazard. A driver entering a road from a driveway, alley, or other place that is not a road yields to all traffic on that road.
- Pedestrians in crosswalks
- — With no working signal, yield to a pedestrian in a crosswalk who is on your half of the road or approaching so closely from the other half as to be in danger. Never pass a vehicle stopped at a crosswalk for a pedestrian.
- School bus
- — Stop at least 10 feet from a school bus stopped to load or unload children, and wait until it moves or the driver signals. On a highway with four or more lanes, oncoming traffic need not stop, but traffic behind the bus must.
- Emergency vehicles
- — When an emergency or public safety vehicle approaches with flashing lights and a siren, yield, pull to the right edge or curb clear of any intersection, and stop until it passes.
- Move over law
- — When passing a stopped emergency, public safety, road service, waste collection, or highway maintenance vehicle with flashing lights on a road with two or more lanes your way, move to a lane not next to it if safe. Otherwise slow down and use caution.
★ Exam points
- Same time with no signs: the driver on the left yields to the driver on the right.
- Turning left: yield to oncoming traffic close enough to be a hazard.
- Pulling out of a driveway or lot: yield to all traffic on the road.
- Stop at least 10 feet from a school bus that is loading or unloading.
- On four or more lanes, oncoming traffic need not stop for a school bus.
- Never pass a vehicle stopped at a crosswalk for a pedestrian.
2-2. Speed, Passing, and Parking
★★★★☆ 25% (estimate)
Overview
This chapter covers how fast you may drive, how to pass safely, and where you may not park. It has many numbers, so it helps to learn them as groups: speed limits, passing distances, and parking distances.
Ohio's basic rule is that you must drive at a speed that lets you stop within the assured clear distance ahead, never faster than is reasonable for traffic, road, and weather. Unless another limit is posted, the limit is 20 mph in a school zone during recess and while children are arriving or leaving, where school speed signs are posted, 15 mph in alleys within a city or village, 25 mph in most other parts of a city or village, 35 mph on state routes in a city or village outside business districts, 55 mph on highways outside cities and villages, and 70 mph on rural freeways.
When you pass on a two-lane road, you must be back in your own lane before you come within 200 feet of an oncoming vehicle. Do not drive on the left side within 100 feet of an intersection or railroad crossing, or near a hill crest or curve where you cannot see. Pass on the right only when the vehicle ahead is turning left or the road has room for two or more lanes your way, and never by driving off the roadway. When someone passes you, keep right and do not speed up.
Parking rules protect firefighters, pedestrians, and drivers' view. Do not park within 10 feet of a fire hydrant, within 20 feet of a crosswalk at an intersection, within 30 feet of a stop sign, yield sign, or traffic signal, or within 50 feet of the nearest rail of a railroad crossing. Do not park on a sidewalk, crosswalk, bridge, or bicycle lane. Next to a curb, park within 12 inches of it.
Key notes
- Assured clear distance ahead
- — Drive no faster than will let you stop within the distance you can clearly see ahead, and never faster than is reasonable for traffic, road surface, and conditions.
- Default speed limits
- — Unless posted: school zone at recess or when children arrive or leave (signs posted) 20 mph; city or village alley 15 mph; most city or village streets 25 mph; state route in a city or village outside a business district 35 mph; highway outside cities and villages 55 mph; rural freeway 70 mph.
- Passing on the left
- — Return to your lane before coming within 200 feet of an oncoming vehicle. Do not drive on the left side within 100 feet of an intersection or railroad crossing, or near a hill crest or curve where your view is blocked.
- Passing on the right
- — Allowed only when the vehicle ahead is making or about to make a left turn, or the road has room for two or more lanes going your way. Never drive off the roadway to pass.
- Being passed
- — Keep to the right and do not increase your speed until the other vehicle has completely passed.
- No-parking distances
- — Do not park within 10 feet of a fire hydrant, 20 feet of a crosswalk at an intersection, 30 feet of a stop sign, yield sign, or traffic signal, or 50 feet of the nearest rail of a railroad crossing.
- Parking at a curb
- — Park with your right-hand wheels parallel to and not more than 12 inches from the right-hand curb.
★ Exam points
- School zone during recess and while children arrive or leave, where school speed signs are posted: 20 mph.
- Most city and village streets: 25 mph. Highways outside cities and villages: 55 mph.
- Return from passing before coming within 200 feet of an oncoming vehicle.
- No driving on the left within 100 feet of an intersection or railroad crossing.
- No parking within 10 feet of a fire hydrant.
- No parking within 50 feet of the nearest rail of a railroad crossing.
2-3. Safe Driving Practices
★★★★☆ 20% (estimate)
Overview
Safe driving habits help you see, be seen, and protect the people in your car. This chapter covers headlights, turn signals, child seats, railroad crossings, sharing the road with bicycles, backing on freeways, car doors, and leaving a car parked.
Ohio requires headlights from sunset to sunrise, whenever you cannot see people and vehicles 1,000 feet ahead, and whenever your wipers are on because of rain or snow. Driving with only parking lights at those times is not allowed. Before turning or changing lanes, signal continuously for at least the last 100 feet.
Children need the right restraint. A child under 4 years old or under 40 pounds must ride in a child safety seat. A child under 8 who is shorter than 4 feet 9 inches and no longer needs a child seat must ride in a booster seat. When passing a bicycle, Ohio law considers 3 feet or more a safe distance.
At a railroad crossing, never drive around or under lowered gates. When signals flash or a train is close, stop between 15 and 50 feet from the nearest rail. On a freeway, never back up; if you miss your exit, go on to the next one. Open a door on the traffic side only when it is safe, and before leaving a car unattended, stop the engine, remove the key, set the parking brake, and on a hill turn the front wheels to the curb or side of the road.
Key notes
- Headlights
- — Required from sunset to sunrise, whenever people and vehicles cannot be seen 1,000 feet ahead, and whenever wipers are in use because of rain, snow, or other precipitation. Parking lights alone are not enough.
- Turn signals
- — Signal continuously during at least the last 100 feet before you turn or move right or left. Also signal before you stop or slow down suddenly.
- Child seats and booster seats
- — Under 4 years old or under 40 pounds: a child safety seat. Under 8 years old and shorter than 4 feet 9 inches: a booster seat. Both must meet federal safety standards.
- Railroad crossings
- — When signals flash, a gate is down, or a train is close, stop within 50 feet but not less than 15 feet from the nearest rail. Never drive through, around, or under a closed or moving gate.
- Passing bicycles
- — When passing a bicycle or electric bicycle, a distance of 3 feet or more is considered a safe passing distance.
- Freeways, doors, and parking
- — Do not back up on a freeway except in a rest area or an emergency. Open a door on the traffic side only when it is safe. Before leaving a car unattended, stop the engine, remove the key, set the parking brake, and on a hill turn the wheels to the curb or side of the road.
★ Exam points
- Headlights are required whenever wipers are on because of rain or snow.
- Use headlights when you cannot see 1,000 feet ahead.
- Signal for at least the last 100 feet before a turn.
- Under 4 years or under 40 pounds: child safety seat.
- Give a bicycle 3 feet or more when passing.
- Never back up on a freeway.
2-4. Temporary Permit (TIPIC) and Probationary License
★★★☆☆ 15% (estimate)
Overview
Ohio uses a step-by-step system for new drivers under 18: first a temporary instruction permit (TIPIC), then a probationary license with limits, and later a full license. This chapter covers the knowledge test, who must ride with a permit holder, and the limits on young drivers.
You can take the knowledge test and apply for a permit at 15 years and 6 months. The test has 40 questions, and you must answer 75% correctly; if you fail, you must wait at least 24 hours to retest. The permit is valid for one year. A permit holder under 16 must drive with a parent, guardian, custodian, or licensed driving instructor beside them. A permit holder 16 or older may drive with any licensed driver at least 21 beside them.
Permit holders under 18 may not drive from midnight to 6 a.m. unless a parent, guardian, or custodian rides beside them. Every person in the car must wear a seat belt, and there may be no more people than seat belts. Before getting a probationary license at 16 or older, a driver under 18 must hold the permit at least 6 months. Every new driver under 21 must also finish a driver training course and complete 50 hours of driving practice with at least 10 at night.
A probationary license still has limits until 18. In the first 12 months, no driving from midnight to 6 a.m. and no more than one passenger who is not a family member unless a parent, guardian, or custodian is along. After 12 months, no driving from 1 a.m. to 5 a.m. Exceptions exist for work, school events, and religious events with written documentation. Permit holders under 18 and probationary drivers may not use a phone in any manner while driving, except in an emergency or when stopped outside a lane of travel.
Key notes
- Temporary instruction permit (TIPIC)
- — Available at 15 years and 6 months after passing the knowledge test and a vision screening. It is valid for one year. You must carry it whenever you drive.
- Who rides with a permit holder
- — Under 16: a parent, guardian, custodian, or licensed driving instructor beside you. 16 or older: a licensed driver at least 21 beside you. The supervising adult must not be over the alcohol limit.
- Knowledge test
- — 40 multiple choice questions on traffic signs and motor vehicle laws. Answer 75% correctly to pass. If you fail, wait at least 24 hours to retest.
- Getting a probationary license
- — At 16 or older. Drivers under 18 must hold the permit at least 6 months. Every new driver under 21 must finish a driver training course and complete 50 hours of driving practice, including at least 10 at night.
- Night limits
- — Permit holders under 18: no driving from midnight to 6 a.m. without a parent, guardian, or custodian beside them. Probationary license, first 12 months: midnight to 6 a.m. After 12 months: 1 a.m. to 5 a.m.
- Passengers and phones
- — First 12 months with a probationary license: no more than one non-family passenger without a parent, guardian, or custodian. Permit holders under 18 and probationary drivers may not use a phone in any manner while driving. First violation: $150 fine and 60-day suspension.
★ Exam points
- The youngest age for a permit is 15 years and 6 months.
- A permit holder under 16 needs a parent, guardian, custodian, or driving instructor beside them.
- Hold the permit at least 6 months before a probationary license.
- Practice 50 hours, including 10 at night.
- Probationary drivers: midnight to 6 a.m. limit in the first 12 months, then 1 a.m. to 5 a.m.
- Young drivers may not use a phone in any manner while driving.
2-5. OVI: Alcohol and Drug Laws
★★★★☆ 15% (estimate)
Overview
In Ohio, driving while impaired by alcohol or drugs is called OVI, short for operating a vehicle impaired. This chapter covers the alcohol limits, the implied consent law, and the penalties for a first offense.
A driver 21 or older is violating the OVI law with a blood alcohol concentration (BAC) of 0.08% or more, and can also be charged at a lower level if alcohol or drugs affect their driving. Drivers under 21 face a much lower limit: 0.02%. The OVI law covers alcohol, drugs of abuse, or a combination, so a legal medicine that impairs your driving can also lead to OVI. Only time lowers BAC; coffee, cold showers, and fresh air do not.
Under Ohio's implied consent law, anyone who drives in Ohio is considered to have agreed to a chemical test if arrested for OVI. Refusing the test for the first time brings a one-year administrative license suspension. Taking the test and testing at or over the limit for the first time brings a three-month suspension.
A first OVI conviction brings a court suspension of 1 to 3 years, a fine of $565 to $1,075, and a mandatory three days in jail or a three-day driver intervention program. Penalties grow with prior offenses, so the safest plan is never to drive after drinking or using drugs.
Key notes
- BAC limits
- — 21 or older: OVI at 0.08% or more. Under 21: illegal at 0.02% or more. A driver can also be charged at a lower level if alcohol or drugs affect their driving.
- Drugs and OVI
- — The OVI law covers driving under the influence of alcohol, a drug of abuse, or a combination of them. A legal medicine that impairs your driving can still lead to OVI.
- Implied consent
- — By driving in Ohio, you are deemed to have consented to a chemical test of your blood, breath, urine, or other body substance if arrested for OVI.
- Administrative suspensions
- — First refusal of a chemical test: one-year suspension. First failed test: three-month suspension. Prior refusals or OVI convictions in the past 10 years make these longer.
- First OVI conviction
- — Court suspension of 1 to 3 years, a fine of $565 to $1,075, and a mandatory three days in jail or a three-day driver intervention program.
- Sobering up
- — Only time lowers the alcohol level in the body. Coffee, cold showers, and fresh air do not lower BAC.
★ Exam points
- Adults violate the OVI law at a BAC of 0.08% or more.
- Drivers under 21 violate the law at 0.02% or more.
- Refusing a chemical test for the first time brings a one-year suspension.
- Failing a chemical test for the first time brings a three-month suspension.
- A first OVI conviction brings a 1 to 3 year court suspension.
- Only time lowers your blood alcohol level.
