To reduce traffic incidents, all new cars sold in the EU must now include driver-monitoring technology, including Driver Drowsiness and Attention Warning (DDAW) systems and, on newer vehicles, Advanced Driver Distraction Warning (ADDW) systems.

Similar requirements are expected in the US, where the National Highway Traffic Safety Administration (NHTSA) has been directed to develop rules requiring advanced impaired driving prevention technology in new passenger vehicles.

The EU requirement took effect on July 7, 2026. In the US, Section 24220 of the 2021 Infrastructure Investment and Jobs Act requires NHTSA to finalize regulations for “advanced impaired driving prevention technology.”

While camera-based systems are widely expected, the law does not specify exactly how manufacturers must implement the technology. Many current systems use infrared cameras to monitor the driver’s face and eyes for signs of drowsiness, distraction, or possible impairment.

Privacy experts raised alarms and they are not alone. Mandated driver‑monitoring tech in new cars raises a set of privacy, security, and civil‑liberties objections.
