What does Maine require?
user
Maine's laws are the strictest in the US: a 10 mile per hour speed limit, all vehicles must be switched to alternate-fuel vehicles by 2025, automakers must reduce per-mile emissions by 25% from 2017 levels by 2025, automakers must sell a certain percentage of alternative fuel vehicles (currently 10% by 2015), and the goal is to require zero-emission vehicles by 2040.
