According to the Connecticut Drivers Manual:
Roundabouts/Rotaries/Circular Intersections Roundabouts or rotaries are intersections that are controlled by a circular island in the center. They may have one lane or two lanes. Entering traffic must yield the right-of-way to circulating traffic. Each road approaching them is marked with a yield sign and may also have yield line markings on the pavement.
They are easy to use. Simply position your vehicle correctly and use your turn signals to indicate where you want to go.
When approaching a roundabout or rotary, slow down. You must yield to traffic proceeding through them. If you plan to turn right, stay to the right as you enter. If you plan to go straight, you may stay in either lane. If you plan to turn left, stay to the left as you enter.
The governing statute is C.G.S.A. Sec. 14-239. Violations of the law are infractions.
Roundabouts improve safety, according to the Insurance Institute for Highway Safety:
Modern roundabouts are much smaller than older traffic circles — also known as rotaries — and roundabouts require vehicles to negotiate a sharper curve to enter. These differences make travel speeds in roundabouts slower than speeds in traffic circles.
Roundabouts promote safety in several ways. At traditional intersections with stop signs or traffic signals, some of the most common types of crashes are right-angle, left-turn, and head-on collisions. These types of collisions can be severe because vehicles may be traveling through the intersection at high speeds. With roundabouts, these types of potentially serious crashes essentially are eliminated because vehicles travel in the same direction and at low speeds— generally less than 20 mph in urban areas and less than 30-35 mph in rural areas. Installing roundabouts in place of traffic signals can also reduce the likelihood of rear-end crashes and their severity by removing the incentive for drivers to speed up as they approach green lights and by reducing abrupt stops at red lights.
Studies of intersections in the United States converted from traffic signals or stop signs to roundabouts have found reductions in injury crashes of 72-80 percent and reductions in all crashes of 35-47 percent.
