Death and injury by driving is a different Act

The Act on Punishment of Acts Causing Death or Injury by Driving was amended by the same Act that amended the Road Traffic Act (Act No. 52 of 2026), but its offences and penalties are its own. This site has not transcribed them. A case involving death or injury is outside this calculator.

The summary-trial procedure is a different Act

The Summary Trial Procedure Act for traffic cases governs HOW a minor traffic case is disposed of. It is procedural and carries no amount of its own, so it is not modelled here. Its ceiling and this offence's own ceiling are two different figures.

Minimum speeds are not transcribed

【道路交通法施行令】Minimum speeds are set by Cabinet Order Art. 27. Arts. 11 and 12 only point at it ("the next Article" / "the preceding Article"); the figure itself is not within what this site transcribed. It was read, and not taken.

Not every Chapter 8 article is covered

【道路交通法】Chapter 8 of the Road Traffic Act (Arts. 117–122) holds more articles than the ones this site joined to the hansokukin ceilings. Only the articles that Appended Table 2's own rows name are transcribed. Arts. 117 and 122, and Arts. 118-2 and 118-3, are referenced by no ceiling row and are not transcribed.

For a juvenile, the family court sets the amount

【道路交通法】Under Road Traffic Act Art. 130-2(1), second sentence, where a case reaches a family-court hearing the amount is set by that court within the Act's own Appended Table 2 ceiling. There is no fixed schedule figure to read off, so this site states none.

The mitigated floor is not stated

Penal Code Art. 15 carries a proviso: on statutory mitigation grounds a court CAN sentence below the floor. This site states only the un-mitigated floor and does not model when mitigation applies.

Expressway mainline default speeds are out of scope

The default speed on an expressway mainline is set by Cabinet Order Art. 27, which this site has not transcribed. The general-road figure is never reused for it. On an expressway, enter the posted limit.

No alcohol or BAC classification

This site's calculators do not classify alcohol readings. There is no verified threshold table here to drive one, and producing a number without it would be the opposite of accuracy.

No "will I lose my licence" prediction

Suspension and revocation from accumulated points are set by the Cabinet Order's Appended Table 3 together with Road Traffic Act Art. 103. Both were read; neither is modelled. There is no such calculator here.

No foreign-licence or visitor-specific rules

Nothing in the material this site read carries rules specific to foreign licences or cross-border drivers. This English bundle is a translation of the same claims and makes no additional ones.

Where to physically pay is not stated here

What the statutes give is the deadline and the no-instalments rule. Counters, banks and opening hours are not sourced, so they are not written. Follow the instructions printed on your own notice.
