The United Nations Economic Commission for Europe (UNECE) has announced several major regulatory shifts in 2025, singling a new era of road safety and advanced vehicle technologies. These changes—set to take effect globally—address emerging challenges posed by modern vehicles, driver behaviour, and automated systems.
Emergency Lane Keeping System (ELKS): A Step Towards Accident Prevention
UNECE has adopted a groundbreaking regulation on Emergency Lane Keeping Systems (ELKS). ELKS are intelligent driver-assist features designed to prevent accidents caused by unintended lane departures, a frequent risk during long and monotonous drives. The system automatically detects when a vehicle is drifting over lane markings unintentionally. If the driver does not react to system warnings, ELKS can quickly and safely steer the vehicle back into its lane, even when adjacent lanes are occupied.
Importantly, the regulation ensures driver autonomy: at any moment, the driver can override the system through deliberate actions like steering or control inputs. The standardized ELKS requirements apply to passenger cars and vans and will be enforceable from February 2026.
Guidance on Data Storage for Automated Driving: Accountability and Transparency
UNECE’s new guidance document covers data storage for vehicles equipped with advanced automated driving systems (ADS), specifically Levels 3, 4, and 5 automation. These vehicles must now record critical safety-related data, such as timestamped control transitions and system interactions. This secure log helps clarify whether
the ADS or the driver was in charge during any incident, improving accountability and enabling accurate evaluation of automated systems’ performance.
The guidance recommends the types of data (sensing, perception, planning, and control) that should be captured, secure storage protocols, and regulated access—ensuring availability to authorized officers and protection of personal data. Manufacturers are required to ensure all records are promptly accessible in a standardized electronic format via internationally recognized interfaces.
Additional Measures: Safer Acceleration Control
UNECE also amended UN Regulation No. 175, governing Acceleration Control for Pedal Error (ACPE). This update aims to prevent sudden, unintended acceleration during slow-speed or creeping maneuvers—a hazard particularly for automatic vehicles—and now extends protections to vans along with cars.
Why These Changes Matter
Enhanced protection for all road users, including occupants of automated vehicles
Greater transparency and accountability during incidents involving automated systems
Push for harmonized standards across member countries, making technology adoption smoother for global manufacturers
Conclusion
As vehicle technologies rapidly evolve, UNECE’s 2025 regulatory changes ensure that safety remains at the forefront. These initiatives establish global benchmarks for accident prevention, data handling in automated vehicles, and smarter acceleration control, paving the way for safer roads around the world.
