Milan Area C is like a special area in Milan where cars have to pay extra money if they want to drive inside it.
Think of it like a big circle on map of Milan that only certain cars can go inside. It's called "Area C" because it's the third circle around the city center.
The reason they made Area C is to help cut down on pollution in Milan. When too many cars are driving around in a small area, it can make the air really dirty and hard to breathe.
So, the government made a rule that if you want to drive in Area C, you have to pay some extra money. This is called a "congestion charge."
The amount of money you have to pay depends on what kind of car you're driving and what time of day it is. At certain times, you may not even be allowed to drive in Area C at all.
The goal of Milan Area C is to make the air cleaner and healthier for everyone who lives in Milan. So, if you're driving there, make sure you check the rules carefully so you can stay safe and healthy!
