Three landmark UN vehicle regulations adopted last June by the World Forum for Harmonization of Vehicle Regulations entered into force on 22 January 2021, as notified by the United Nations Secretary General. 

The three Regulations are applicable in the 54 countries that are Parties to the 1958 Agreement.  

This is the first international regulation governing vehicles’ cybersecurity. It introduces, among others, audit related provisions that allow the assessment of the robustness of the cyber security measures implemented by manufacturers and the way manufacturers and their suppliers are able to mitigate cybersecurity related risks as well as obligation to perform risks assessments and to keep them current. It also imposes a number of requirements, including the obligation to monitor and report on incidents. It is referred to in UN Regulation No. 157, given that automated driving systems must be appropriately protected against cybersecurity risks. 

Some Countries and Regions had already announced that they would implement this Regulation and make it compulsory: 

  • Japan indicated that it transposed the Regulation in January 2021 and that it will become mandatory for new vehicle types from July 2022 (if no OTA functionality, January 2024) and for new vehicles produced from July 2024 (if no OTA functionality, May 2026). 

  • Korea announced that the Ministry of Land, Infrastructure and Transport plans to implement it by 2022. 

  • In the European Union, the regulation will be mandatory for all new vehicle types from July 2022 and will become mandatory for all new vehicles produced from July 2024. 

  • UN Regulation No. 156 on Software Updates and Software Updates Management Systems 

Software updates, including over-the-air updates may play an increasing role in the automotive sector. This is expected to be true because of the benefits it can bring in order to mitigate cyber security risks. It might find also applications in order to update automated driving systems as technical progress is made. This new UN Regulation provides a new dimension to the Type Approval system, which did not such situations in the past. This is the first international regulation governing vehicles’ Over the air (OTA) software updates.    

This is the first international regulation governing the introduction of so-called “level 3” systems with a limited use case on motorways, and especially traffic jam situations. It includes a number of safety requirements, driver monitoring related provisions of importance when driver is requested to take back the driving tasks as well as provisions for Data Storage Systems for Automated Driving a kind of black box that will collect data related to the system and its use as well as Driver monitoring. 

Under the leadership of the USA, China Japan, Canada, the Netherlands and Germany, the World Forum’s Working Party on Automated/Autonomous and Connected Vehicles is working on safety provisions applicable across all Automated Driving Systems. Extensions of the scope of UN Regulation No. 157 are also being considered separately, notably higher speeds on motorways, allowing for lane changes, and application of the UN Regulation to trucks. 

Note to editors 

UN Regulations enter into force six months after their adoption by the World Forum. This is the time given to contracting Parties to the UN Vehicles agreements to notify the United Nations Office of Legal Affairs about their opposition to the adopted text, or their intention not to adopt its provisions, and to provide Countries with sufficient time for implementation.
