Roundabouts
The essentials
This topic explains the general logic of entering, driving around and leaving a roundabout. Priority must be determined according to the signs installed at that location and the general rules, not from the circular shape alone.
What to remember
A roundabout sign by itself does not mean that traffic already circulating always has priority; priority is also determined by signs at the entrance and any active control. Choose the correct lane before entering, maintain your lane while circulating, and signal in good time before leaving without cutting across the path of a vehicle in an adjacent lane.

A traffic circle is arranged at the intersection. The roadway you are approaching an intersection has two lanes. Which lane do you have to take to turn when entering the intersection?
- Right lane
- Left lane
- Right or left lane
The correct answer: Right or left lane
A roundabout may be entered from either the right or left lane unless signs or lane markings prescribe another arrangement. Choose the lane according to the intended exit and avoid abrupt lane changes. When entering, also obey the priority signs and yield to traffic that has the right of way.
Which driver is violating traffic rules while exiting a roundabout?
- The light vehicle driver
- Both drivers
- No one
The correct answer: The light vehicle driver
The correct answer is “The light vehicle driver”. The order is determined by active control and priority signs, then by road status and, under equal conditions, the right-hand rule and intersecting paths. Remember the order: control → priority signs/road status → right-hand rule when conditions are equal.
The red car:
- Has right of way, because it is approaching the roundabout from the right of the blue car.
- Must yield to the blue car already traveling on the roundabout.
The correct answer: Must yield to the blue car already traveling on the roundabout.
The correct answer is “Must yield to the blue car already traveling on the roundabout.”. The order is determined by active control and priority signs, then by road status and, under equal conditions, the right-hand rule and intersecting paths. Remember the order: control → priority signs/road status → right-hand rule when conditions are equal.
