WASHINGTON, Sept 10 (Reuters) - The federal government

is barring states from allowing electric vehicles and other

clean cars to use carpool lanes without meeting vehicle

occupancy requirements starting Oct. 1, California officials

said on Wednesday.

California Governor Gavin Newsom said single drivers with

the state's Clean Air Vehicle decal will no longer be able to

use carpool lanes or receive reduced toll rates in some areas.

California and other states had used the perk to incentivize

the sale of EVs. The Trump administration has taken aim at EVs

on a number of fronts.
