MLIT Panel Discusses Safety Measures for Level 4 Vehicles, Including Recalls After Accidents

jidounten-lab.com reported on November 13, 2026, that a vehicle safety measures panel at the Ministry of Land, Infrastructure, Transport and Tourism discussed a proposal to allow administrative sanctions related to recalls of Level 4 autonomous vehicles after even a single accident. According to the article, the panel considered the direction of measures outlined in an MLIT document dated November 4, 2026. The materials provided do not confirm whether the system has been finalized or when it might take effect.

The MLIT panel discussed recalls after accidents involving Level 4 vehicles, reporting and notification of accident information, and safety measures for vehicles being converted to Level 4. For operators and parties involved in vehicle conversions, the focus of the system’s design includes not only responses after an accident but also safety checks during conversions. Specific obligations and criteria have not yet been provided.

The central issue described in the article is not whether conventional recall decisions based on the number of accidents can simply be applied to Level 4 vehicles, but how to identify safety problems in vehicles that do not assume a driver is present and ensure they are corrected. The proposal for administrative sanctions after a single accident was reported as an opinion raised at the panel, and should not be treated as an established regulatory standard. It is necessary to distinguish between an accident occurring and a determination that measures such as a recall are necessary, and to follow how the responsible decision-maker and criteria are defined going forward. The three items cited in the article address not only responses to vehicle defects, but also the collection of accident information and the process of converting existing vehicles to Level 4, within a single safety framework. The inclusion of recalls, accident reports to MLIT and notifications to the Japan Transport Safety Board, and safety measures during conversions means that both corrective action after operations begin and management of changes to vehicle specifications are under consideration. However, the specific requirements for each item and how the procedures relate to one another cannot be confirmed from the article text provided. In an article about levels of autonomous vehicles, we distinguished explanations of the levels from confirmation of approvals and functions. The current discussion likewise raises the point that the Level 4 designation alone does not determine safety or applicable conditions, and that measures for accidents and methods of checking conversions need to be set separately. A report that Waymo’s fully driverless vehicles have surpassed 300 million miles cumulatively covers driving records, but reported mileage and accident reporting or recall decisions under Japan’s regulatory system are different measures. The scale of driving records cannot, by itself, serve as a substitute for domestic regulatory requirements. The next points to watch are the criteria for linking a single accident to a sanctions decision, the scope and deadlines for accident reports, the division of responsibilities for notifications to the Japan Transport Safety Board, and who conducts safety checks after a conversion and at what stage. The article reports on the panel’s discussion and the anticipated development of the proposal, but does not specify finalized standards, covered vehicles or operator procedures. Until these are set out, the headline’s reference to a recall after a single accident should not be treated as a finalized system and should be distinguished from an opinion still under consideration.

The discussion is taking place at a panel overseen by Japan’s Ministry of Land, Infrastructure, Transport and Tourism, and concerns safety measures for operating and converting Level 4 vehicles in Japan. How the three items—recall decisions after accidents, accident reporting and notification, and checks during conversions—are developed into procedures and standards will directly affect domestic operators.
