Brazil
6. Roundabout
A roundabout is a circular road arrangement in which traffic travels around a central island in one designated direction. Vehicles enter and leave through connecting roads, and traffic signs or local rules determine who has priority.
Drivers should reduce speed, choose a suitable lane, observe all road users and signal as required when leaving. The direction of travel, entry priority, lane use and rules for cyclists and pedestrians depend on local traffic signs and regulations.

Who has priority at a roundabout in Brazil?
At an unsigned Brazilian rotatória, the Traffic Code gives priority to vehicles already circulating. Follow the actual signs or signals where they regulate the junction.

How should you choose a roundabout lane in Brazil?
Choose your intended exit before entering and follow the lane arrows and destination signs. Keep to the marked route and make any permitted lane change only when safe; having priority over entering traffic does not give you priority to change lanes.

What should you check when leaving a roundabout in Brazil?
Check the lane you will cross or enter, signal the manoeuvre as required and look for cyclists and pedestrians at the exit. Obey any separate crossing controls and do not force an exit across another vehicle’s path.
