Mandatory National Standard GB 47955-2026 Deep Dive: Unified Legal Standards for L2 ADAS Data Forensics
On 2026-6-27, the national mandatory standard GB 47955—2026 "Safety Requirements for Combined Driving Assistance Systems for Intelligent Connected Vehicles" was officially released. Effective from 2027-1-1, this is China's first mandatory national standard for L2-level autonomous driving. Appendix F, "Data Recording Requirements," establishes a unified national baseline for in-vehicle electronic forensics. Covering data storage, recorded fields, read protocols, and anti-overwrite mechanisms, it provides statutory authority to support police on-site investigations and judicial appraisals with lossless verification.

How to Preserve Evidence in Autonomous Driving Incidents
When an accident occurs while assisted driving is active, automakers often shift blame to the driver for failing to take over in time. To prove it was a vehicle issue, the key is to immediately secure multi-dimensional objective evidence—most critically, dashcam footage and EDR data.
