Will the US ban new gas-powered car sales in any state by 2029?

California and several other states have adopted Advanced Clean Cars II rules mandating 100% zero-emission new vehicle sales by 2035. However, no state has implemented a full ban before that target date, and the 2029 deadline is well ahead of schedule. Political and legal challenges, including potential federal preemption and court challenges to state emission waiver authority, create significant obstacles. While ambitious states might accelerate timelines, a full ban by 2029 faces both practical and legal hurdles.

Resolves YES if any US state formally bans the sale of new gasoline-powered passenger vehicles and the ban takes effect before January 1, 2029. Partial restrictions (e.g., requiring a percentage of EV sales) do not count.
