A 3-minute lesson from the New York course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
A modern roundabout is a circular intersection where traffic moves counterclockwise around a central island and entering traffic yields. Low speeds and curved entrances make roundabouts safer than many ordinary intersections, as long as everyone follows the yield-at-entry rule.
A common roundabout design: central island, splitter islands, crosswalks and yield lines
Modern roundabout
A circular intersection with yield control of entering traffic, where traffic moves counterclockwise around a central island.
You approach a single-lane roundabout. A car is circling toward you from the left and a pedestrian is in the crosswalk. Yield to both, then enter when there's a gap. Signal right as you near your exit and yield again to anyone in the exit crosswalk.

What is the maximum design speed for vehicles circulating inside a modern roundabout?
30 mph or less
45 mph or less
15 mph or less
There is no design speed limit
Answer: 30 mph or less
Roundabouts are designed so vehicle speed is restricted to 30 mph or less within the circle.
