Question 1Korean traffic controls and vulnerable road users

At a red traffic light, what is the basic safe-driving response?

  1. Stop before the stop line or crosswalk Correct answer.
  2. Speed up to clear the intersection
  3. Honk and continue if no car is visible
  4. Stop only if pedestrians are already in the lane

Explanation

A red signal requires stopping before the conflict area, normally at the stop line or before the crosswalk. Stopping early protects pedestrians and keeps the intersection clear.

Question 2Korean traffic controls and vulnerable road users

A yellow traffic light appears as you approach an intersection. What should you normally do if you can stop safely?

  1. Accelerate to beat the red light
  2. Stop before entering the intersection Correct answer.
  3. Change lanes inside the intersection
  4. Ignore it because yellow means go

Explanation

A yellow signal warns that the signal is changing and you should stop if it can be done safely. Entering only because you want to beat the red light increases crash risk.

Question 3Korean traffic controls and vulnerable road users

What does a red circular road sign with a diagonal slash through a symbol usually mean?

  1. The action shown is prohibited Correct answer.
  2. The action shown is required
  3. The road is scenic
  4. The road is reserved for parking

Explanation

A red circle with a slash is a prohibition sign. The symbol inside tells you what action is not allowed, such as a turn, entry, or parking movement.

Question 4Korean traffic controls and vulnerable road users

What is the safest meaning to remember for a warning sign before a curve, crossing, or other hazard?

  1. Increase speed to reduce travel time
  2. Prepare to slow down and look for the hazard Correct answer.
  3. Park on the shoulder to read the sign
  4. Ignore the sign if traffic is light

Explanation

Warning signs alert you to conditions ahead that may require lower speed, more space, or special attention. They are meant to give you time to adjust before the hazard.

Question 5Korean traffic controls and vulnerable road users

When a pedestrian is crossing at a crosswalk in front of you, what should you do?

  1. Stop and let the pedestrian cross safely Correct answer.
  2. Drive around the pedestrian if there is space
  3. Flash your headlights and continue
  4. Sound the horn so the pedestrian hurries

Explanation

Korean road rules require drivers to protect pedestrians at crosswalks. Stopping before the crosswalk gives the pedestrian a clear and safe path.

Question 6Korean traffic controls and vulnerable road users

In a child protection zone, what speed limit may be used to protect children?

  1. Up to 30 km/h Correct answer.
  2. At least 50 km/h
  3. At least 80 km/h
  4. No limit if school is closed

Explanation

Official Korean legal guidance notes that child protection zones may limit vehicle speed to within 30 km/h. Drivers should expect children to move unpredictably near schools and similar facilities.

Question 7Korean traffic controls and vulnerable road users

What should you do at a stop sign or stop line?

  1. Slow down only if another car is close
  2. Come to a complete stop before proceeding safely Correct answer.
  3. Stop after the front wheels enter the crosswalk
  4. Treat it as a parking place

Explanation

A stop control requires a complete stop at the proper position before you enter the conflict area. After stopping, proceed only when it is safe and lawful.

Question 8Korean traffic controls and vulnerable road users

What does a solid center line generally warn you not to do?

  1. Pass or cross into the opposite lane unless a lawful exception applies Correct answer.
  2. Use your headlights
  3. Reduce tire pressure
  4. Drive only at night

Explanation

A solid center line separates opposing traffic and generally restricts crossing or passing. It is used where crossing would be especially risky.

Question 9Korean traffic controls and vulnerable road users

What should you do when approaching a pedestrian crossing with people waiting near the curb?

  1. Prepare to slow or stop and watch both sides Correct answer.
  2. Speed up so they wait longer
  3. Drive in the opposing lane
  4. Look only at the traffic light far ahead

Explanation

People waiting near a crossing may step out quickly. Slowing, scanning both sides, and being ready to stop protects pedestrians and prevents surprise braking.

Question 10Korean traffic controls and vulnerable road users

What does a guide sign generally help drivers with?

  1. Direction, destinations, or route information Correct answer.
  2. Mandatory braking force
  3. Alcohol testing
  4. Seat-belt installation

Explanation

Guide signs help drivers navigate by giving route, direction, destination, or service information. They are different from warning or regulatory signs.

Question 11Korean traffic controls and vulnerable road users

Why is it dangerous to enter an intersection when traffic ahead is stopped even though your signal is green?

  1. You may block cross traffic when the signal changes Correct answer.
  2. Green signals never allow straight travel
  3. It automatically cancels your license
  4. It is safe because the signal protects you from all directions

Explanation

A green light permits movement only when you can clear the intersection safely. If you stop inside the intersection, you can block cross traffic and pedestrians when the phase changes.

Question 12Korean traffic controls and vulnerable road users

At an uncontrolled intersection, two vehicles arrive at about the same time from roads of similar width. Which vehicle should normally be yielded to?

  1. The vehicle on your left
  2. The vehicle on your right Correct answer.
  3. The vehicle with the louder horn
  4. The vehicle with newer registration

Explanation

Korean Road Traffic Act rules for uncontrolled intersections include yielding to the vehicle on the right when vehicles enter at the same time. This rule prevents hesitation where no signal or officer controls the movement.

Question 13Korean traffic controls and vulnerable road users

When turning left at an uncontrolled intersection, whom should you yield to if another vehicle is going straight or turning right?

  1. Yield to the straight or right-turning vehicle Correct answer.
  2. Make the other vehicle yield because you are turning left
  3. Yield only to buses
  4. Yield only if your vehicle is manual transmission

Explanation

At an uncontrolled intersection, a left-turning driver should yield to vehicles going straight or turning right through the intersection. Turning across another path creates a conflict that must be controlled by yielding.

Question 14Korean traffic controls and vulnerable road users

You are turning right and pedestrians are lawfully crossing the road you are entering. What should you do?

  1. Stop and let them finish crossing safely Correct answer.
  2. Turn behind them at walking speed without stopping
  3. Honk so they clear the crosswalk
  4. Move into the crosswalk to show your intent

Explanation

Turning traffic must not endanger or obstruct pedestrians crossing lawfully. Stop before the crossing area and proceed only after the path is clear.

Question 15Korean traffic controls and vulnerable road users

On a narrow road with no marked lanes, what should you do when passing close to a pedestrian?

  1. Slow and keep a safe distance Correct answer.
  2. Drive faster so the encounter is shorter
  3. Use the horn continuously
  4. Move as close as possible to the pedestrian

Explanation

The Road Traffic Act requires special care around pedestrians on narrow roads, including safe distance and slow movement. The driver controls the heavier, faster vehicle and must reduce risk.

Question 16Korean traffic controls and vulnerable road users

A pedestrian is on a safety island or refuge area in the road. What driver behavior best matches the duty to protect pedestrians?

  1. Slow down and keep a safe distance Correct answer.
  2. Drive closer to discourage crossing
  3. Ignore the pedestrian because the island is not a crosswalk
  4. Stop on the safety island

Explanation

Korean road rules require careful driving when pedestrians are in safety zones. Slowing and leaving space protects the pedestrian if they move unexpectedly.

Question 17Korean traffic controls and vulnerable road users

Which driving behavior is most appropriate near a bus stop where passengers are getting on or off?

  1. Slow down and watch for pedestrians stepping out Correct answer.
  2. Pass at high speed before the bus moves
  3. Drive partly onto the sidewalk
  4. Focus only on vehicles behind you

Explanation

People near a stopped bus may cross in front of or behind it with limited visibility. Lower speed and scanning around the bus reduce the chance of hitting a hidden pedestrian.

Question 18Korean traffic controls and vulnerable road users

Which sign meaning is most likely shown by a blue circular sign with a directional arrow?

  1. A mandatory direction or required movement Correct answer.
  2. A warning of falling rocks
  3. A prohibition on all vehicles
  4. A tourist destination only

Explanation

Blue circular signs commonly indicate mandatory movements, such as a required direction. The driver must follow the indicated movement unless another lawful control applies.

Question 19Korean traffic controls and vulnerable road users

A sign prohibits entry from your direction. What should you do?

  1. Enter slowly if the road looks empty
  2. Do not enter; choose another lawful route Correct answer.
  3. Enter only with hazard lights on
  4. Reverse down the road to avoid the sign

Explanation

A no-entry control means traffic from your direction must not enter that roadway. Choosing another route prevents head-on conflicts with lawful traffic.

Question 20Korean traffic controls and vulnerable road users

What does a maximum-speed-limit sign require?

  1. Do not drive faster than the displayed limit Correct answer.
  2. Drive exactly at the displayed limit in all conditions
  3. Drive at least the displayed limit
  4. Ignore lower speeds when road conditions are poor

Explanation

A maximum speed limit sets the highest lawful speed under normal conditions. Bad weather, traffic, or visibility may require a lower safe speed.

Question 21Korean traffic controls and vulnerable road users

What does a minimum-speed-limit sign require on a road where it applies?

  1. Drive no slower than the displayed speed unless unavoidable Correct answer.
  2. Drive no faster than the displayed speed
  3. Stop every kilometer
  4. Use only the shoulder

Explanation

A minimum speed limit keeps traffic flow from becoming dangerously slow. Congestion, weather, emergencies, or other unavoidable conditions may still require lower speed.

Question 22Korean traffic controls and vulnerable road users

When a lane-control signal above your lane shows a red X, what should you do?

  1. Do not use that lane Correct answer.
  2. Speed up in that lane
  3. Stop under the signal and wait
  4. Use the lane only for passing

Explanation

A red X over a lane means the lane is closed or not available to your direction. Move out of it safely before the closure or avoid entering it.

Question 23Korean traffic controls and vulnerable road users

A green arrow signal points left while the circular red signal is also displayed. What does the arrow allow?

  1. Only the movement indicated by the green arrow, if safe Correct answer.
  2. All movements through the intersection
  3. A right turn only
  4. Parking in the intersection

Explanation

A green arrow gives permission for the indicated movement while other movements may remain stopped. You still must yield to pedestrians and any conflicting lawful traffic.

Question 24Korean traffic controls and vulnerable road users

If a police officer's hand signal conflicts with a traffic light, which should you follow?

  1. The traffic light only
  2. The police officer's direction Correct answer.
  3. The vehicle behind you
  4. Whichever lets you move faster

Explanation

Traffic control by an authorized officer takes priority when it conflicts with a signal. Officers may override lights to manage incidents, congestion, or hazards.

Question 25Korean traffic controls and vulnerable road users

What is the best response when a ball rolls into the road from between parked cars?

  1. Slow immediately and expect a child may follow Correct answer.
  2. Drive over it without changing speed
  3. Swerve into oncoming traffic
  4. Honk and accelerate

Explanation

A ball entering the road is a strong clue that a child may run after it. Slowing early gives you time to stop before the hidden pedestrian appears.

Question 26Korean traffic controls and vulnerable road users

At a marked crosswalk, why should you avoid passing a vehicle that has stopped ahead of you?

  1. The stopped vehicle may be yielding to a hidden pedestrian Correct answer.
  2. Passing is always faster and safer
  3. The stopped vehicle has lost its license
  4. Crosswalks are only for vehicles

Explanation

A stopped vehicle at a crosswalk may hide a pedestrian from your view. Passing it can put your vehicle directly into the pedestrian's path.

Question 27Korean traffic controls and vulnerable road users

What does a flashing yellow traffic signal generally require from a driver?

  1. Proceed with caution after checking for hazards Correct answer.
  2. Stop and remain until the signal is repaired
  3. Drive at expressway speed
  4. Ignore all cross traffic

Explanation

A flashing yellow signal means caution. Drivers should slow as needed, check the intersection, and proceed only when safe.

Question 28Korean traffic controls and vulnerable road users

What does a flashing red signal generally require?

  1. Stop, then proceed only when safe Correct answer.
  2. Speed through before it changes
  3. Treat it as a green arrow
  4. Park in the intersection

Explanation

A flashing red signal is treated like a stop control. Stop first, check all directions, and proceed only when it is safe and lawful.

Question 29Korean traffic controls and vulnerable road users

When making a U-turn where it is allowed, what should you do first?

  1. Check signs, signals, road markings, and surrounding traffic Correct answer.
  2. Turn immediately from any lane
  3. Use the horn instead of signaling
  4. Stop across all lanes to create space

Explanation

A lawful U-turn depends on signs, markings, signal control, and traffic gaps. It must be made from the proper position without endangering others.

Question 30Korean traffic controls and vulnerable road users

Why should you not park close to an intersection or crosswalk where stopping is prohibited?

  1. It can block visibility and pedestrian movement Correct answer.
  2. It makes your car easier to wash
  3. It improves traffic flow
  4. It is allowed if hazard lights are on

Explanation

Parking near intersections and crosswalks can hide pedestrians and approaching vehicles. It also forces other road users into unexpected paths.

Question 31Korean traffic controls and vulnerable road users

A child is standing on the right sidewalk near a marked crosswalk, and a parked van blocks part of your view. What should you do?

  1. Slow enough to stop before the crosswalk if the child enters Correct answer.
  2. Keep speed because the child is still on the sidewalk
  3. Move left without checking to get more space
  4. Sound the horn and maintain speed

Explanation

The parked van creates a hidden-zone hazard, and children can enter suddenly. Slowing to a speed that allows stopping before the crosswalk is the safest choice.

Question 32Korean traffic controls and vulnerable road users

You approach a green light, but an elderly pedestrian is still crossing slowly in the crosswalk. What should you do?

  1. Wait until the pedestrian is safely clear Correct answer.
  2. Drive behind the pedestrian if there is a small gap
  3. Use the horn so the pedestrian hurries
  4. Proceed because your signal is green

Explanation

A green vehicle signal does not remove the duty to avoid endangering pedestrians. Waiting protects a vulnerable pedestrian who may need more time to finish crossing.

Question 33Korean traffic controls and vulnerable road users

A driver ahead stops suddenly for a pedestrian at an unmarked crossing location where pedestrians are allowed to cross. What should you do?

  1. Stop safely and do not pass the stopped vehicle Correct answer.
  2. Pass because there is no painted crosswalk
  3. Honk and steer around both vehicle and pedestrian
  4. Drive onto the sidewalk to avoid delay

Explanation

Korean road rules protect pedestrians crossing even where no crosswalk is installed in allowed situations. A stopped vehicle may be shielding the pedestrian from your view.

Question 34Korean traffic controls and vulnerable road users

A signal is green, but a traffic officer is holding a stop gesture toward your lane. What should you do?

  1. Stop and follow the officer's direction Correct answer.
  2. Proceed because green lights outrank officers
  3. Go only if other drivers behind you honk
  4. Turn around in the intersection

Explanation

An authorized officer's direction controls when it conflicts with a traffic signal. The officer may be managing an incident or hazard you cannot see.

Question 35Korean traffic controls and vulnerable road users

At a multi-lane crosswalk, a vehicle in the next lane stops although your lane looks clear. What should you assume?

  1. A pedestrian may be hidden, so slow or stop before passing the crosswalk Correct answer.
  2. The driver stopped only to use a phone
  3. You have priority because your lane is open
  4. You should speed through before a pedestrian appears

Explanation

A stopped vehicle near a crosswalk can block your view of a pedestrian. The safe assumption is that someone may be crossing from behind the stopped vehicle.

Question 36Korean traffic controls and vulnerable road users

You are entering a roundabout or circular intersection where traffic is already circulating. What is the safest approach?

  1. Slow and yield to circulating traffic and pedestrians as required Correct answer.
  2. Enter quickly because entering traffic has priority
  3. Stop inside the circle to choose a lane
  4. Change lanes suddenly at the exit

Explanation

Circular intersections require low speed, scanning, and yielding to traffic already in the circle where applicable. Pedestrians at entries and exits also need protection.

Question 37Korean traffic controls and vulnerable road users

A navigation app tells you to turn, but a posted sign prohibits that turn. What should you do?

  1. Obey the posted traffic control and let the app reroute Correct answer.
  2. Follow the app because it is newer
  3. Turn only if no police officer is visible
  4. Stop in the lane and manually reprogram the app

Explanation

Traffic signs and signals are legal road controls; navigation apps are only aids. Obey the sign, continue safely, and let the route update.

Question 38Korean traffic controls and vulnerable road users

You are approaching a school zone at 30 km/h, but children are running near the curb and visibility is poor. What is the best speed choice?

  1. Slow below 30 km/h if needed to stop safely Correct answer.
  2. Stay exactly at 30 km/h because it is always safe
  3. Accelerate to leave the zone sooner
  4. Use the horn instead of reducing speed

Explanation

A posted or zone limit is a maximum under suitable conditions, not a guaranteed safe speed. Children and poor visibility require a lower speed that lets you stop in time.

Question 39Observation, spacing and changing road conditions

What is the best reason to leave extra following distance behind another vehicle?

  1. It makes lane changes unnecessary
  2. It gives you time to stop if the vehicle ahead brakes Correct answer.
  3. It lets you use a phone safely
  4. It allows you to exceed the speed limit

Explanation

Following distance is your time buffer. More distance gives you time to notice, decide, and brake before a rear-end crash develops.

Question 40Observation, spacing and changing road conditions

When roads are wet, what should you do with your speed and following distance?

  1. Drive faster and follow closer
  2. Keep normal speed but brake harder
  3. Reduce speed and increase following distance Correct answer.
  4. Use only the parking brake

Explanation

Wet pavement reduces tire grip and increases stopping distance. Slowing down and opening the gap gives the tires more margin before skidding or hydroplaning.

Question 41Observation, spacing and changing road conditions

Before changing lanes, what should you do?

  1. Signal, check mirrors and blind spots, then move only if safe Correct answer.
  2. Move first and signal afterward
  3. Rely only on the rearview mirror
  4. Change lanes quickly without checking if traffic is slow

Explanation

A safe lane change starts with communication and observation. Signaling, mirror checks, and blind-spot checks help prevent sideswipe crashes.

Question 42Observation, spacing and changing road conditions

What should you do when an emergency vehicle is approaching from behind with siren or warning lights?

  1. Compete with it for the lane
  2. Yield and make way as safely as possible Correct answer.
  3. Stop in the middle of the intersection
  4. Ignore it unless it touches your lane

Explanation

Drivers must give priority to emergency vehicles and clear a path without creating a new hazard. Move aside or stop where it is safe and predictable.

Question 43Observation, spacing and changing road conditions

What is the legal blood alcohol concentration threshold for drunk driving under Korean road traffic law?

  1. 0.01 percent or higher
  2. 0.03 percent or higher Correct answer.
  3. 0.08 percent or higher
  4. 0.10 percent or higher

Explanation

Korean legal guidance identifies 0.03 percent blood alcohol concentration or higher as the drunk-driving threshold. The safest rule is not to drive after drinking at all.

Question 44Observation, spacing and changing road conditions

What is the safest action if you feel sleepy while driving?

  1. Open a window and keep driving for hours
  2. Pull over at a safe place and rest Correct answer.
  3. Follow another vehicle closely
  4. Use the horn to stay alert

Explanation

Drowsiness slows reaction time and can cause brief sleep episodes. The safe response is to stop at a safe place and rest before continuing.

Question 45Observation, spacing and changing road conditions

When entering traffic from a roadside parking place, what should you do first?

  1. Signal and yield to traffic already on the road Correct answer.
  2. Pull out quickly to make others stop
  3. Reverse into the nearest lane
  4. Use the horn instead of checking

Explanation

Traffic already moving on the road has little time to react to a parked vehicle pulling out. Signaling, checking, and yielding make your movement predictable.

Question 46Observation, spacing and changing road conditions

What should you do if your vehicle begins to skid on a slippery road?

  1. Brake hard and jerk the steering wheel
  2. Ease off the accelerator and steer smoothly Correct answer.
  3. Shift to reverse
  4. Close your eyes briefly

Explanation

A skid requires calm, smooth control so tires can regain grip. Abrupt braking or steering often makes the skid worse.

Question 47Observation, spacing and changing road conditions

What is the safest response to thick fog?

  1. Use high beams and drive faster
  2. Slow down, increase distance, and use appropriate lights Correct answer.
  3. Follow taillights closely
  4. Turn off all lights

Explanation

Fog reduces visibility and makes judging distance harder. Lower speed, more space, and appropriate low or fog lights help you see and be seen.

Question 48Observation, spacing and changing road conditions

When passing a bicycle or slow two-wheeled vehicle, what is the safest general approach?

  1. Leave enough side clearance and pass only when safe Correct answer.
  2. Pass closely to save space
  3. Honk continuously while passing
  4. Cut back in immediately after the front bumper clears

Explanation

Two-wheeled road users can wobble or avoid obstacles suddenly. Adequate side clearance and patience prevent contact and panic reactions.

Question 49Observation, spacing and changing road conditions

Which habit best reduces distraction while driving?

  1. Set navigation and phone controls before moving Correct answer.
  2. Read messages only on straight roads
  3. Hold the phone low so others cannot see
  4. Type only at red lights

Explanation

Planning navigation and communications before driving reduces eyes-off-road and hands-off-wheel time. A driver still needs full attention in traffic and at signals.

Question 50Observation, spacing and changing road conditions

On an expressway with a posted minimum speed, when may driving below the minimum be acceptable?

  1. When traffic congestion or unavoidable conditions make it necessary Correct answer.
  2. Whenever you want to save fuel
  3. Only when using a mobile phone
  4. Whenever the road is straight

Explanation

Korean speed guidance recognizes that drivers should not go below minimum speed except for unavoidable reasons such as congestion. Very low speed on a fast road can create rear-end and lane-change hazards.
