15. 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 Spain?
At a Spanish glorieta, vehicles already on the circular carriageway have priority over vehicles entering, subject to the controlling signs or signals. A divided circular junction with a road running through the island is not treated as an ordinary glorieta merely because of its shape.

How should you choose a roundabout lane in Spain?
Follow the lane signs and markings. On an ordinary roundabout, arrange to reach the outer lane before your exit, giving way to traffic already in any lane you wish to enter. Urban lane-choice rules and specially marked layouts can differ; do not cut across another vehicle to reach an exit.

What should you check when leaving a roundabout in Spain?
Normally leave from the outer right-hand lane and signal the exit. If you cannot move there safely in time, continue round rather than cut across another lane. Watch for pedestrians and cyclists at the exit and obey any special lane markings or signals.
