Question 11

When stopping behind another vehicle on an uphill slope, do not get too close, as the vehicle ahead may roll backward and collide with you.

Accepted Answer

✓ True

The Rules of the Road (1) states: "When stopping behind another vehicle on an uphill slope, do not get too close. The vehicle ahead may roll backward and collide with you." This statement is correct.

Question 12

On a downhill slope, it is best to use the foot brake primarily and apply engine braking as a supplement when necessary.

Accepted Answer

✕ False

The Rules of the Road (4) states: "Use a low gear and utilize engine braking. On a long downhill slope, using the foot brake too frequently can cause the brakes to suddenly fail, which is dangerous." Engine braking should be used primarily.

Question 13

When starting on an uphill slope, it is safer to start using only the clutch operation without using the handbrake.

Accepted Answer

✕ False

The Rules of the Road (2) states: "When starting on an uphill slope, use the handbrake whenever possible. If you try to start using only the clutch operation, you may fail and the vehicle may roll backward, colliding with the vehicle behind you." Using the handbrake is recommended.

Question 14

You must not overtake the vehicle ahead at corners or curves.

Accepted Answer

✓ True

The Rules of the Road 2 (5) clearly states: "You must not overtake the vehicle ahead at corners or curves." This statement is correct.

Question 15

On slopes, because starting on an uphill is difficult, the vehicle going uphill should yield to the vehicle going downhill as a general rule.

Accepted Answer

✕ False

The Rules of the Road (6) states: "On slopes, because starting on an uphill is difficult, the vehicle going downhill should yield to the vehicle going uphill." The downhill vehicle should yield as a general rule. However, when there is a turnout nearby, the uphill vehicle should also pull into the turnout and wait.

Question 16

When approaching a corner or curve, slow down sufficiently on the straight section before it.

Accepted Answer

✓ True

The Rules of the Road 2 (1) clearly states: "When approaching a corner or curve, slow down sufficiently on the straight section before it." This statement is correct. Turning the steering wheel at high speed can easily cause a rollover or skid.

Question 17

On a road where one side is a cliff with a risk of falling, when safe passing is not possible, the vehicle on the mountain side should stop and yield.

Accepted Answer

✕ False

The Rules of the Road (8) states: "On a road where one side is a cliff with a risk of falling, when safe passing is not possible, the vehicle on the cliff side should stop and yield." The vehicle on the cliff side should yield.

Question 18

Which of the following is correct regarding driving on a downhill slope?

Accepted Answer

B: Keep a greater following distance

The Rules of the Road (5) states: "On a downhill slope, keep a greater following distance. It is dangerous because the vehicle accelerates and the stopping distance becomes longer." Keeping a greater following distance on a downhill slope is correct.

Answer

On a downhill, gravity shortens the braking distance, so you may keep less following distance than on level ground

Answer

Keep a greater following distance

Answer

To prevent vapor lock, use only engine braking and never use the foot brake at all

Answer

Tap the brake pedal several times to warn the vehicle behind while closing the gap to the vehicle ahead

Question 19

When driving an automatic transmission vehicle on a long downhill slope, how should you operate the shift lever?

Accepted Answer

C: Shift to 2 or L (or 1)

The Rules of the Road (4) states: "On a downhill slope, use a low gear (in an automatic transmission vehicle, shift the lever to 2 or L (or 1)) and utilize engine braking." Shifting to 2 or L (or 1) is correct.

Answer

Stay in D and turn the overdrive (O/D) switch ON

Answer

Stay in D and keep the foot brake lightly applied to reduce speed

Answer

Shift to 2 or L (or 1)

Answer

Stay in D and apply the parking (hand) brake while driving to prevent the foot brake from overheating

Question 20

Which of the following is incorrect regarding driving near the top of an uphill slope?

Accepted Answer

C: Accelerate sufficiently to pass through

The Rules of the Road (3) states: "Near the top of an uphill slope, visibility is poor, so slow down to a stop-ready speed (jokō). Also, you must not overtake there." Slowing down is required. The statement about accelerating sufficiently to pass through is incorrect.

Answer

Slow down to a stop-ready speed because visibility is poor

Answer

You must not overtake

Answer

Accelerate sufficiently to pass through

Answer

Pay attention to oncoming vehicles

Question 21

At night, visibility worsens and your sense of speed becomes dull, making it easy to exceed the speed limit. Therefore, you need to reduce your speed and drive more carefully than during the day.

Accepted Answer

✓ True

The Rules of the Road section "Night Driving (1)" clearly states that "at night, visibility worsens," "your sense of speed becomes dull and you tend to exceed the speed limit," and "reduce your speed and drive carefully compared to daytime." The question accurately reflects this content.

Question 22

Even during the day, when passing through places such as inside tunnels or thick fog where you cannot see 100 meters ahead, you must turn on your headlights.

Accepted Answer

✕ False

The Rules of the Road section "2. Lights (1)" clearly states "even during the day, when passing through places such as inside tunnels or thick fog where you cannot see 50 meters ahead (200 meters on expressways)." The question states "100 meters," which is incorrect.

Question 23

When passing oncoming vehicles or driving directly behind another vehicle, you must dim your headlights or switch to low beam.

Accepted Answer

✓ True

The Rules of the Road section "2. Lights (2)" clearly states that "when passing oncoming vehicles or driving directly behind another vehicle, you must dim your headlights or switch to low beam." The question matches this completely.

Question 24

While driving, pedestrians near the right side of the road may become invisible due to the lights from your vehicle and oncoming vehicles, so you need to be very careful.

Accepted Answer

✕ False

The Rules of the Road section "1. Night Driving (2)" states that "pedestrians near the center of the road may become invisible due to the lights from your vehicle and oncoming vehicles." The question says "right side," but the correct location is "center."

Question 25

At night, when unavoidably stopping or parking on an expressway, it is sufficient to turn on your hazard lights, parking lights, or tail lights, and there is no need to place a warning triangle.

Accepted Answer

✕ False

The Rules of the Road section "2. Lights (6)" clearly states that "at night, when unavoidably stopping or parking on an expressway, in addition to turning on your hazard lights, parking lights, or tail lights, you must place a warning triangle." Both lights and a warning triangle are required.

Question 26

Many accidents occur during twilight hours, so you need to turn on your lights early to make your vehicle visible to others.

Accepted Answer

✓ True

The Rules of the Road section "1. Night Driving (6)" clearly states that "many accidents occur during twilight hours, so turn on your lights early to make your vehicle visible." The question accurately reflects this content.

Question 27

Interior lights, including those in taxis, must not be turned on while driving.

Accepted Answer

✕ False

The Rules of the Road say interior lights (except in buses) should not be turned on while driving, but this is a recommendation — there is no legal obligation barring ordinary vehicles or taxis from turning on interior lights while driving. The mandatory wording "must not be turned on" is therefore incorrect. (Route buses, by contrast, are required to keep their interior lights on at night.)

Question 28

What does the Rules of the Road identify as a point to be careful of when following a vehicle ahead?

Accepted Answer

B: Pay attention to its brake lights

The Rules of the Road section "1. Night Driving (4)" clearly states, "When following a vehicle ahead, pay attention to its brake lights." When driving at night, watching the brake lights of the vehicle ahead allows you to detect deceleration or stopping early.

Pay attention to its brake lights

Answer

Pay attention to its license plate

Answer

Pay attention to the following distance

Question 29

Which of the following is the correct way to use headlights?

Accepted Answer

B: Except in busy urban areas, use high beam to detect pedestrians early

The Rules of the Road section "2. Lights (2)" states, "Except when driving in areas such as busy urban streets, use high beam to detect pedestrians and others as early as possible." High beam is the standard outside urban areas, and should be switched to low beam when passing oncoming vehicles or following other vehicles.

Answer

In busy urban areas, always drive with high beam

Answer

Except in busy urban areas, use high beam to detect pedestrians early

Answer

When passing oncoming vehicles, always switch to high beam

Answer

When driving directly behind another vehicle, switch to high beam

Question 30

What does the Rules of the Road identify as the proper use of headlights before intersections or curves with poor visibility?

Accepted Answer

C: Switch your headlights to high beam or flash them to alert others of your approach to the intersection

The Rules of the Road section "2. Lights (4)" clearly states, "Before intersections or curves with poor visibility, switch your headlights to high beam or flash them to alert other vehicles and pedestrians of your approach to the intersection." This makes your vehicle's presence and approach known to others.

Answer

Turn off your headlights to check the reactions of other vehicles and pedestrians

Answer

Fix your headlights on low beam to show consideration for oncoming vehicles

Answer

Switch your headlights to high beam or flash them to alert others of your approach to the intersection

Answer

Dim your headlights and enter slowly while slowing down to a stop-ready speed

Question 31

On rainy days, you must drive more carefully than on clear days by reducing speed and maintaining sufficient following distance.

Accepted Answer

✓ True

Chapter 6, Section 4 of the Rules of the Road clearly states: "On rainy days, reduce your speed compared to clear days, maintain sufficient following distance, and drive carefully." Rain creates poor conditions including reduced visibility and slippery road surfaces, making this response necessary.

Question 32

Paved roads at the beginning of rainfall are relatively non-slippery, so you may drive at normal speed.

Accepted Answer

✕ False

The Rules of the Road states: "Paved roads at the beginning of rainfall are prone to slipping, so be careful." At the start of rain, oil and other substances on the road surface rise up, making it even more slippery. Driving at normal speed is dangerous.

Question 33

Driving through deep puddles can allow water to enter the brake drum, which may cause the brakes to stop working or work poorly.

Accepted Answer

✓ True

Chapter 6, Section 4 of the Rules of the Road states: "Driving through deep puddles can allow water to enter the brake drum, which may cause the brakes to stop working or work poorly, so avoid them."

Question 34

When passing near pedestrians or storefronts, it is desirable to reduce speed to avoid splashing mud or water.

Accepted Answer

✕ False

The Rules of the Road states: "When passing near pedestrians or storefronts, you must reduce speed to avoid splashing mud or water." The wording is "must" rather than "desirable," indicating an obligation, so this question statement is incorrect.

Question 35

On snowy or icy roads, you can drive on all roads as long as you have tire chains, snow tires, or studless tires equipped.

Accepted Answer

✕ False

The Rules of the Road states: "On roads where signs prohibit passage of vehicles without tire chains, you must not drive without tire chains on your tires." There are roads where snow tires or studless tires alone are not sufficient for passage.

Question 36

In fog or blizzards, you should turn on fog lights if available, or headlights if not, early.

Accepted Answer

✓ True

Chapter 6, Section 4 of the Rules of the Road states: "Fog and blizzards severely limit visibility. If you have fog lights (light yellow auxiliary headlights), turn on fog lights; if not, turn on headlights early." Early lighting is necessary because visibility becomes severely limited.

Question 37

When driving on rainy days, sudden start, sudden steering, and sudden braking are particularly dangerous because they can cause rollover or skidding.

Accepted Answer

✓ True

The Rules of the Road states: "Sudden acceleration, sudden steering, and sudden braking can cause rollover and skidding, and are particularly dangerous." On rainy days, road surfaces become slippery, so sudden maneuvers increase the risk of rollover and skidding.

Question 38

Which of the following is correct regarding the use of studded tires as stated in the Rules of the Road?

Accepted Answer

B: Studded tires cause road surface damage and dust generation, so avoid using them on roads other than snowy or icy roads.

The Rules of the Road states: "Studded tires cause road surface damage and dust generation on roads other than snowy or icy roads, so avoid using them." The content indicates that use should be avoided on roads other than snowy or icy surfaces.

Answer

Studded tires can be used on roads other than snowy or icy roads.

Answer

Studded tires cause road surface damage and dust generation, so avoid using them on roads other than snowy or icy roads.

Answer

Studded tires are prohibited on all types of roads.

Answer

Studded tires can only be used on streetcar tracks.

Question 39

Which of the following is stated in the Rules of the Road regarding precautions when driving on snowy roads?

Accepted Answer

B: Reduce speed sufficiently, maintain sufficient following distance, and drive along existing tire tracks as much as possible.

The Rules of the Road states: "Reduce your speed sufficiently, maintain sufficient following distance, and drive" and "Try to drive along tire tracks as much as possible." The correct response is to pay attention to both speed and following distance, and to drive along existing tire tracks.

Answer

Reduce speed sufficiently, maintain sufficient following distance, and drive along fresh snow as much as possible.

Answer

Reduce speed sufficiently, maintain sufficient following distance, and drive along existing tire tracks as much as possible.

Answer

Speed can be normal, but maintain sufficient following distance and drive along existing tire tracks as much as possible.

Answer

Reduce speed sufficiently, following distance can be normal, and drive along existing tire tracks as much as possible.

Question 40

Regarding steel plates at construction sites and streetcar tracks when driving on rainy days, which of the following is stated in the Rules of the Road?

Accepted Answer

C: They are slippery and dangerous.

The Rules of the Road states: "Steel plates at construction sites and streetcar tracks are also slippery and dangerous." These road surfaces become particularly slippery in rainy weather, so caution is required.

Answer

No particular caution is necessary.

Answer

Friction increases compared to normal, so increase speed when passing.

Answer

They are slippery and dangerous.

Answer

You must stop and check before proceeding.

Question 41

If your engine stalls at a railroad crossing or in an intersection, you can move the vehicle as an emergency measure by putting the gear in low or second and using the starter motor.

Accepted Answer

✓ True

The Rules of the Road (1) states: "In such cases, as an emergency measure, you can put the gear in low or second and use the starter motor (starting electric motor) to move the vehicle." However, this method cannot be used with automatic transmission vehicles.

Question 42

Even with an automatic transmission vehicle, if the engine stalls you can move the vehicle by putting the gear in low and using the starter motor.

Accepted Answer

✕ False

The Rules of the Road (1) notes: "This method cannot be used with automatic transmission vehicles or vehicles equipped with a device that prevents the engine from starting unless the clutch pedal is depressed." Therefore, this method cannot be used with automatic transmission vehicles.

Question 43

When wheels spin in mud or similar conditions, using old blankets or gravel as traction aids is effective.

Accepted Answer

✓ True

The Rules of the Road (2) states: "When wheels spin in mud or similar conditions, if you have old blankets, gravel, etc., using them as traction aids is effective." The use of old blankets or gravel as traction aids is recommended.

Question 44

While driving, if the engine speed increases and then fails to decrease due to malfunction, which is the correct action for a four-wheeled vehicle?

Accepted Answer

B: Shift the gear to neutral to prevent engine power from being transmitted to the wheels, stop in a safe place, and then turn off the engine switch

The Rules of the Road (3) states: "In the case of a four-wheeled vehicle, shift the gear to neutral to prevent engine power from being transmitted to the wheels, proceed to a safe place such as the shoulder of the road, stop there, and then turn off the engine switch." The correct procedure is to stop in a safe place before turning off the switch.

Answer

Turn off the engine switch immediately

Answer

Shift the gear to neutral to prevent engine power from being transmitted to the wheels, stop in a safe place, and then turn off the engine switch

Answer

Shift the gear to low and decelerate using engine braking

Question 45

If a tire goes flat while driving, avoid sudden braking and stop by applying the brakes intermittently.

Accepted Answer

✓ True

The Rules of the Road (4) states: "If a tire goes flat while driving, grip the steering wheel firmly and devote all your effort to straightening the vehicle's direction. Avoid sudden braking and stop by applying the brakes intermittently." Avoiding sudden braking and applying brakes intermittently is the correct action.

Question 46

When the rear wheels begin to skid, it is important to first apply the brakes to reduce speed.

Accepted Answer

✕ False

The Rules of the Road (5) states: "When the rear wheels begin to skid, you must not apply the brakes. First release the accelerator and at the same time use the steering wheel to straighten the vehicle's direction." Applying the brakes is an incorrect action. Releasing the accelerator is correct.

Question 47

When the rear wheels skid to the right, the vehicle turns to the right, so turn the steering wheel to the left to straighten it.

Accepted Answer

✕ False

The Rules of the Road (5) states: "When the rear wheels skid to the right (left), the vehicle turns to the left (right), so turn the steering wheel to the right (left)." When the rear wheels skid to the right, the vehicle turns to the left, so turning the steering wheel to the right is correct. The statement in the question is reversed and therefore incorrect.

Question 48

Which of the following is NOT listed in the Rules of the Road as a measure to take when brakes fail on a downhill slope?

Accepted Answer

C: Turn off the engine switch

The Rules of the Road (6) describes measures such as "downshift quickly and pull the handbrake. If that still does not stop the vehicle, drop the wheels into a ditch on the mountain side," etc., but there is no mention of turning off the engine switch. Therefore, option 3 is correct.

Answer

Downshift quickly

Answer

Pull the handbrake

Answer

Turn off the engine switch

Answer

Drop the wheels into a ditch on the mountain side

Question 49

If a head-on collision with an oncoming vehicle becomes likely, use the horn and brakes simultaneously and swerve to the left as much as possible.

Accepted Answer

✓ True

The Rules of the Road (7) states: "If a head-on collision with an oncoming vehicle becomes likely, use the horn and brakes simultaneously and swerve to the left as much as possible." Using the horn and brakes simultaneously and swerving to the left is the correct action.

Question 50

When there is a risk of a head-on collision with an oncoming vehicle, you should avoid leaving the roadway even if the area off the road is not dangerous.

Accepted Answer

✕ False

The Rules of the Road (7) states: "If the area off the road is not dangerous, you must not hesitate to leave the roadway." If the area off the road is safe, you should actively leave the roadway and not avoid doing so. Therefore, the statement in the question is incorrect.

Question 51

When passing through a railroad crossing, you must always come to a complete stop, open the window, and confirm safety to the left and right with your own eyes and ears, in all cases.

Accepted Answer

✕ False

The Rules of the Road require a complete stop immediately before a railroad crossing as a general rule, but as an exception, when there is a traffic signal at the crossing, you may pass through according to the signal, and a complete stop is not necessarily required.

Question 52

When stopping or parking on a road at night, you must always turn on the hazard lights, parking lights, or tail lights.

Accepted Answer

✕ False

The Rules of the Road require lights when stopping or parking at night as a general rule, but as an exception, when you are stopped or parked in a location visible from 50 meters behind due to street lighting or when you have placed an emergency warning device, you do not need to turn on lights.

Question 53

The area beyond the railroad crossing was a bit congested, but I judged that traffic would start moving soon, so I followed the vehicle in front and entered the crossing.

Accepted Answer

✕ False

The Rules of the Road state that when the area beyond the railroad crossing is congested and continuing forward would risk becoming immobilized within the crossing, you must not enter. Entering based on the subjective judgment that traffic will "start moving soon" is a violation.

Question 54

While driving on a main road at night, I felt a little drowsy, but because there was little traffic, I continued driving while opening the window to let in fresh air.

Accepted Answer

✕ False

The Rules of the Road state that continuing monotonous driving on main roads for a long time causes drowsiness, and while opening the window to prevent drowsiness is recommended, if you become even slightly drowsy, you must stop the vehicle in a safe place and rest. Regardless of traffic volume, continuing to drive when feeling drowsy is dangerous.

Question 55

In dense fog during the daytime when visibility is less than 100 meters, you must turn on your headlights, clearance lights, tail lights, and other lights while driving.

Accepted Answer

✕ False

The Rules of the Road specify that you must turn on your lights when driving in places where you cannot see 50 meters ahead, such as in tunnels or dense fog, even during the daytime. The correct distance is 50 meters, not 100 meters.

Question 56

In dense fog on an expressway when visibility is less than 100 meters, you must turn on your headlights, clearance lights, tail lights, and other lights while driving.

Accepted Answer

✓ True

The Rules of the Road set the threshold for turning on headlights and other lights in tunnels or dense fog at 50 meters of visibility on regular roads and 200 meters on expressways. On an expressway where you cannot see 100 meters ahead, you naturally cannot see 200 meters either, so this meets the threshold and the lights are required.

Question 57

Within 10 meters before and after the edge of a railroad crossing, you must not stop even for loading or unloading cargo.

Accepted Answer

✓ True

Within 10 meters before and after the edge of a railroad crossing, stopping and parking are prohibited regardless of the reason. Brief stopping for loading or unloading cargo or for boarding and alighting of passengers is not permitted. This is an important regulation to prevent accidents near railroad crossings (Road Traffic Act Article 44, Paragraph 1, Item 4; Rules of the Road, Chapter 5, Section 8). Note that this is a different distance from the 5 meters before and after crosswalks.
