Speaker 1 (00:01): How to drive a roundabout. A modern roundabout is a form of intersection control that has one-way counterclockwise circulation around a central island. Entering traffic must slow to 15 to 20 miles per hour and yield to circulating traffic. While approaching the roundabout, use the same caution as approaching a yield sign. If necessary, stop and wait for a sufficient gap of the circulating traffic before entering. Vehicles already inside the roundabout have the right of way. It is courteous to signal right when exiting the roundabout. Here's an example of through movement. And here's an example of right turn movement. Here's an example of left turn movement. Truck aprons are the red concrete adjacent to the circulating roadway, and it's designed for large trucks, buses, and emergency vehicles to maneuver around the circulatory roadway. No other vehicles should drive on the aprons.
