NHTSA Adopts Rule Requiring Automatic Emergency Braking on Light Vehicles

On May 9, 2024, the National Highway Traffic Safety Administration (NHTSA) published a final rule adopting a Federal Motor Vehicle Safety Standard (FMVSS) that requires automatic emergency braking (AEB) systems in U.S. light vehicles and trucks by September 2029. The rule is required under the Bipartisan Infrastructure Law of 2021 (BIL), in which Congress directed NHTSA to establish FMVSS requirements for AEB systems as well as three other Level 2 advanced driver assistance systems (ADAS): lane departure warnings, lane-keeping assist, and forward collision warnings (FCW).


National Highway Traffic Safety Administration Finalizes Model Year 2024-26 Vehicle Fuel Economy Standards

On Friday, April 1, the National Highway Traffic Safety Administration (NHTSA) announced its final fuel economy standards for model year 2024-26 vehicles. The final rule increases vehicle efficiency requirements, as represented through vehicle-footprint-based targets, 8% annually for model years 2024 and 2025 and 10% for 2026, which the agency concludes represents the maximum feasible level manufactures can achieve for these model years. NHTSA predicts that the new standards will yield an industrywide average fuel economy of approximately 49 miles per gallon for model year 2026 passenger cars and light trucks, which represents an increase of 10 miles per gallon over model year 2021.
