it can be fused but it should be used as it's directed

From the Asheville Drivers Manual:

Traffic circles can be tricky, but with just a little caution and common sense they can be an efficient means of getting you where you want to go. Just remember these helpful tips:

1. When approaching a traffic circle, stay alert! Observe traffic patterns around you. Is there an automobile already within the traffic cirle? If so, do not enter the traffic circle. Stop and wait for assistance.

2. Look around. Can you see another automobile from where you are, either directly or in a rear-view, side-view, or vanity mirror? If so, do not enter the traffic circle. Stop and wait for assistance.

3. Think back. How has your journey been so far? Do remember seeing any other automobiles at any time today? How about last week? Last month? Ever? If so, do not enter the traffic circle. Stop and wait for assistance.

4. While waiting for assistance, turn down the volume on your car stereo system and tune into your surroundings. Do you hear honking behind you? If so, that is the sign of an impatient driver. He's probably half-German and thinks he knows how to drive better and more efficiently than you do. He's right. Regardless, do not enter the traffic circle. Stop and wait for the angry man behind you to get tired, grow old, and die. That'll teach him.

Happy driving, Asheville!
