A roundabout is a special type of intersection where cars go in a circle instead of straight through. Imagine a big circle with some other smaller circles on it to help cars move around. When you enter a roundabout, you have to give way to the cars already in it. Don't worry, there are signs and arrows to guide you which way to go. So, you have to drive carefully and slow down as you approach the circle. You keep moving around the circle until you find the exit you need to take. Remember, you always have to give way to cars coming from your right, just like in a regular intersection. Roundabouts are really safe and they help traffic flow better because cars don't have to wait for red lights or stop signs.
