Practice test for the knowledge check
True/False questions on the basics of Japanese traffic rules, in the format used since October 2025. Every answer comes with the reason, because the reason is what you carry into the exam room.
The free bank holds 200 questions and each test draws 50 of them, so a second attempt is never the same test. They are written by us and are awaiting expert review.
A study aid, not an official source
We are not affiliated with the police or any government body. The questions on this site are written by us — the real exam questions are prepared by each prefectural Public Safety Commission and are not published. Rules, fees and procedures differ by prefecture and can change: always confirm with the official page of the license center where you will apply. Every fact here was checked on 25 August 2026, with its source linked beside it.
One example from each topic
The bank covers 14 topics. Here is the first question from each, with the answer — open one to see how the explanations work.
In Japan, vehicles must keep to the left side of the road.
TRUE — Japan drives on the left and the driver's seat is on the right. Keep left as a matter of course, especially just after pulling out of a parking lot or a side street.
Topic: Basics
A flashing red signal means the same as a stop sign: stop, check it is safe, then proceed.
TRUE — Flashing red is a stop instruction. Rolling through it is treated as ignoring a stop signal.
Topic: Signals & signs
At an intersection with no signals where both roads are the same width, the vehicle coming from your left has priority.
TRUE — Left has priority. Coming from a right-hand-traffic country, this is the rule most likely to catch you out.
Topic: Priority & intersections
If a pedestrian is waiting to cross at a crossing with no traffic light, it is enough to slow down and pass carefully.
FALSE — You must stop and let them cross. This is watched closely on the driving check and is heavily enforced.
Topic: Pedestrians
On an ordinary road with no speed limit sign, the legal maximum for a passenger car is 60 km/h.
TRUE — Where no sign is posted, 60 km/h applies on ordinary roads. A posted sign always takes priority over it.
Topic: Speed & stopping distance
You may park within 5 meters of an intersection for a few minutes if you stay in the car.
FALSE — Within 5 meters of an intersection or its corners, both stopping and parking are prohibited. Staying in the car changes nothing.
Topic: Stopping & parking
When turning left you should move over to the left edge of the road in advance.
TRUE — Closing the gap early stops a bicycle or motorcycle slipping up your inside — a very common cause of serious collisions.
Topic: Turning, lanes & overtaking
As a rule you must stop just before a railroad crossing and check that it is safe, even when the barrier is up.
TRUE — Stop and confirm by eye and ear. The exception is a crossing with a traffic signal showing a proceed indication.
Topic: Railway crossings
One small beer is acceptable if you feel completely normal afterwards.
FALSE — There is no safe amount. Driving with alcohol in your body is an offence, whatever you feel.
Topic: Alcohol & fitness to drive
Passengers in the rear seats do not have to wear a seat belt.
FALSE — Belts are required in every seat. In a crash an unbelted rear passenger is thrown into the people in front.
Topic: Occupant & load safety
Holding a mobile phone and talking on it while driving is prohibited.
TRUE — Penalties for this were raised sharply in 2019, and it is heavily enforced.
Topic: Phones & devices
After a minor collision, if both drivers agree the damage is small, you may settle privately and drive away.
FALSE — You must stop, help anyone injured, remove danger and report to the police. Not reporting is an offence in itself.
Topic: Accidents & breakdowns
Pedestrians, bicycles and mopeds must not use an expressway.
TRUE — Small motorcycles are also excluded. The speed difference is what makes them lethal there.
Topic: Expressways
A bicycle is a vehicle and as a rule rides on the left side of the roadway.
TRUE — Expect bicycles on the road with you, traveling in your direction on your left.
Topic: Cyclists & vulnerable road users
