WASHINGTON (Reuters) - A U.S. auto safety agency said Friday it is reconsidering a landmark rule from the administration of former President Joe Biden requiring nearly all new cars and trucks by 2029 to have advanced automatic emergency braking systems.

The National Highway Traffic Safety Administration said it would delay the effective date to March 20 "to give department officials the opportunity for further review and consideration of new regulations."

The Alliance for Automotive Innovation, representing General Motors (NYSE: GM ), Toyota Motor (NYSE: TM ), Volkswagen (ETR: VOWG_p ) and other automakers, last week filed suit to block the rule.
