President Trump’s “Regulatory Freeze Pending Review” Presidential memorandum, which asks agencies to consider postponing the effective date of any rules that have been published in the Federal Register but have not yet taken effect, could impact the new NHTSA final rule related to automatic emergency braking (AEB) technology.

The AEB final rule, published in May 2024, will require all new light vehicles to be equipped with automatic braking systems that meet certain performance requirements by Sept. 1, 2029. The “freeze” does not change this final rule or compliance date.
