Car Smog vs. Clean Patrol: California's Super Rules! 🚗💨🌟

Imagine there's a big, important rulebook for how clean cars should be across the whole country. This rulebook helps keep our air fresh so we can all breathe easier and play outside without coughing!

Now, some states, like California, have a special superpower. They have permission to make their own rules even *stronger* than the national ones! Think of it like a teacher letting one student do extra credit because they want to learn even more. California uses this superpower to make sure cars and trucks in their state produce even less yucky stuff called 'smog' that pollutes the air.
