California said on Tuesday it has withdrawn its request for a federal waiver to require commercial truckers to transition to zero-emissions vehicles, preempting an expected denial from the incoming administration of President-elect Donald Trump.

California officials are withdrawing their final requests to enforce their nation-leading electric vehicle rules, days before President-elect Donald Trump's inauguration.

Because Trump is unlikely to approve them, California has no choice but to abandon its groundbreaking rules for zero-emission trucks and cleaner locomotives.
