You come to a New Jersey traffic circle. A YIELD sign faces you at the entrance, and several cars are already moving around the circle. What should you do?

Correct answer: Slow down, let the cars in the circle go by, and enter when there is a safe gap.

Why

The manual says New Jersey has no set rules for traffic circles: the traffic pattern that each circle has had for years, a major highway running through it, and the stop or yield signs at its entrances decide who goes first. Always check the signs and watch what the drivers already in the circle are doing before you enter. When nothing tells you who has the right-of-way, use the basic rule for an uncontrolled intersection: the vehicle on the left yields to the vehicle on the right.
