Our sources and method

Every practice statement is written from a published rule text: the National Police Agency's rules for road traffic (交通の方法に関する教則, consolidated to September 4, 2024), the Road Traffic Act and its orders on e-Gov, and the agency's pages on the 2026 changes. Each explanation names the rule and links to it. Facts about the test itself come only from police and government pages, with the date we checked them (last: October 23, 2026).

Where the statements come from

交通の方法に関する教則 (rules for road traffic), published by the National Police Agency: the rule book the written tests are based on. Government notices are not protected by copyright in Japan (Copyright Act, article 13), so we can quote them.
The Road Traffic Act (道路交通法), its Enforcement Order and Enforcement Regulations on e-Gov, and the National Police Agency's pages on the 2025–2026 changes.

We do not write from blogs, apps, other prep sites, other question banks or memory. We never copy or imitate a question from the test or from a commercial question bank.

How a statement is made

We first extract each rule with its exact reference and page (for example "教則第6章第2節 1(1), p. 62") and an English wording that adds nothing to the source.
Statements are written only from those extracts: one idea per statement, in plain English. A statement is true only if the cited rule fully says so, and false only if the rule clearly contradicts it. Where the answer would depend on something the rule does not say, we do not write the statement.
Every statement is checked twice, blind: two independent checks that see only the statement and the cited rule text (not our answer). A statement is kept only if both agree with our answer and neither finds it ambiguous.
About half of the statements are false, as on a true/false test, and the five mock tests share no statement.

"Must" and "should"

The rule book mixes duties (しなければなりません, "must") with advice (しましょう, "should"). Our statements keep that difference: a statement built on advice says "should", never "must".

When rules change

The rule book's latest consolidated text is dated September 4, 2024. Later changes (passing cyclists, blue tickets for cyclists, 30 km/h on roads without a center line, stricter drunk and dangerous driving rules) are written from the amendment notices, the law texts and the agency's pages. See 2026 traffic rule changes.

Facts about the test

The number of statements, time, pass mark, languages and the list of exempt countries come only from police and government pages, each cited where it is used, with the date we checked it. Pass rates come from National Police Agency figures as reported by Nikkei and NHK, and we say so wherever we use them.

Found a mistake?

Write to [email protected] with the test letter and statement number. If the cited rule says something else, we fix or remove the statement.
