New federal mandates will require all new passenger vehicles, starting around late 2026 to 2027, to incorporate advanced impaired driving prevention technology. This system, mandated by the 2021 Infrastructure Investment and Jobs Act, utilizes infrared cameras and sensors to continuously monitor driver alertness and sobriety. If the AI detects impairment (e.g., blood alcohol content of 0.08% or higher) or significant drowsiness, it can prevent the vehicle from starting or limit its speed. Beyond the federal oversight, manufacturers could potentially share this biometric data with third parties like insurance companies. The technology is expected to increase vehicle costs by $100-500 per unit, a price likely passed to consumers. Automakers have voiced concerns regarding the technology’s reliability and potential negative impact on sales due to customer backlash.
