EU Regulation 2019/2144 requires camera-based driver monitoring systems in all new vehicles from July 2024

Regulation (EU) 2019/2144 amended type-approval rules to mandate advanced driver distraction warning systems. The technical requirements reference UN ECE Regulation 159 and specify camera or equivalent sensor fusion with infrared illumination for low-light operation. Compliance testing began in 2022 for new models, with full fleet coverage for all registrations by 2026. Data from Euro NCAP 2023 protocols show current production systems achieve 92% detection accuracy on validated drowsiness benchmarks.

The mandate coincides with existing eCall and event data recorder requirements, creating a combined in-cabin sensor suite that logs attention state alongside crash data. No public technical specification requires on-device deletion of video streams; retention rules remain under member-state GDPR implementations. Parallel Chinese and US NHTSA proposals reference the same ISO 20924 drowsiness metrics, indicating regulatory convergence rather than isolated EU action.

OEMs must now integrate DMS into existing ADAS compute nodes, raising per-vehicle BOM cost by an estimated 18-25 euros according to 2023 supplier teardown data. Aftermarket circumvention devices already appear on EU marketplaces, mirroring seatbelt alarm bypass patterns observed post-2000s mandates. Enforcement will rely on periodic technical inspections rather than real-time telematics audits.

Production volumes imply 10-12 million new EU-registered vehicles annually will carry certified DMS hardware by 2027. Software update pathways for false-positive tuning remain unspecified in the regulation text.
