A 3-minute lesson from the Louisiana course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Roundabouts are circular intersections that reduce congestion and the conflicts that cause crashes at ordinary intersections. The key rule: traffic entering yields to traffic already circulating.
Know the rule
Vehicles travel counterclockwise around a raised center island, and entering traffic yields to circulating traffic.
Don't move into the center lane too soon; the longer you're in it, the more likely you'll meet someone coming the other way. Watch for vehicles pulling out of entrances and side streets.
You want to turn left at a roundabout. Signal left on the approach, yield to circulating cars, then enter to the right and go counterclockwise. About three-quarters of the way around, switch to your right signal and exit.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
When entering a roundabout, who has the right-of-way?
Traffic already circulating
The entering vehicle always has priority
Whoever is turning right
The vehicle on the left
Answer: Traffic already circulating
Entering traffic must yield to vehicles already circulating in the roundabout.
