ExploreAbout this exam
The Japan Medium Vehicle Class 1 License (中型自動車一種免許) is a Japanese driving credential that sits between ordinary and large vehicle licences. It covers vehicles with a gross vehicle weight between 5 and 11 tonnes, a maximum payload between 3 and 6.5 tonnes, or passenger capacity of 11 to 29 people plus the driver. Drivers who already hold an ordinary licence and need to operate mid-size trucks, delivery lorries, or small buses typically pursue it. The written examination (学科試験) tests traffic law as it applies to these larger vehicles, plus safe-driving judgment, vehicle handling characteristics, cargo and passenger limits, adverse-condition and emergency procedures, maintenance and pre-trip checks, accident response and first-aid duties, and driver responsibility. Questions are presented in Japanese on paper, usually in true/false (maru-batsu) and multiple-choice form. Preparation should combine careful study of the official traffic-law text with repeated practice questions, then a review of the specific numbers that medium vehicles change: weight ceilings, speed limits, following distances, and loading rules. Because the vehicle is heavier and taller than a passenger car, expect questions that reward anticipating stopping distance, blind spots, and rollover risk rather than memorising signs alone.

What you'll study
About Japan Medium Vehicle Theory preparation
What is the format of the medium vehicle written exam?
It is a paper-based test delivered in Japanese. Expect true/false (maru-batsu) items and multiple-choice questions covering traffic law, safe driving, vehicle characteristics, loading, emergencies, maintenance, and accident duties. You mark answers on a sheet; no driving is involved in the written stage.
How long is the exam and how many questions are there?
Question counts and time limits are set by the licensing authority and can change, so confirm the current figures on the official police or licensing centre website before your test date. Do not rely on numbers from older study guides or forum posts.
What score do I need to pass?
The passing threshold is published by the official licensing authority, and it differs from the ordinary licence exam. Check the current requirement at the centre where you will sit the test. This page deliberately does not quote a figure because it may be revised.
Can I retake the exam if I fail?
Yes, retakes are generally possible, but the schedule, fees, and any waiting period are set by the licensing authority. Ask at the centre or check its website for the current retake procedure, and use the failure to target the domains where you lost the most marks.
How difficult is it compared with the ordinary licence test?
Most candidates find it harder because the law questions are applied to heavier vehicles. Weight limits, load distribution, stopping distance, and speed rules differ from ordinary cars. If you already drive a car, the risk is answering from habit instead of from medium-vehicle rules.
In what order should I study?
Start with traffic law and licence classification, since those rules frame everything else. Then study vehicle characteristics and loading limits, followed by adverse conditions, emergencies, maintenance, and accident duties. Finish with timed practice sets so you can spot repeated mistakes before test day.
What do candidates most often get wrong?
Common errors are mixing up ordinary and medium vehicle weight and capacity thresholds, underestimating stopping distance when loaded, and treating blind-spot and rollover questions as general common sense. Another frequent slip is skimming true/false items and missing a single qualifying word.
Do I need to study first aid and accident reporting?
Yes. Accident response, reporting obligations, and basic first aid appear on the exam. Know your duty to stop, help, and report, and understand the basic priorities at a scene. These questions are few but easy to answer correctly with focused review.

No. This is an independent study resource and is not affiliated with any Japanese government agency, police department, or driving school. Always confirm exam rules, fees, and schedules with the official licensing authority before making plans.
