Postpones the implementation and enforcement of the advanced clean trucks regulations

This bill delays the requirement for truck manufacturers to sell more zero-emission vehicles. It postpones enforcement of the Advanced Clean Trucks rules, which would have mandated increasing sales of zero-emission trucks for medium and heavy-duty vehicles starting before January 1, 2027. The bill sets the effective date for these requirements to January 1, 2027, instead of earlier. This directly affects manufacturers of medium and heavy-duty trucks by extending the timeline for compliance.
