In Portugal, drivers must yield to vehicles already circulating within the roundabout when entering. This 'cedência de passagem' (giving way) rule applies regardless of the number of lanes, unless specific signage indicates otherwise.
Generally, use the rightmost lane for the first exit. For subsequent exits or for straight-ahead traffic, choose the lane that best suits your intended exit, following lane markings and signs. The Código da Estrada and specific road signage are the ultimate guides.
Common errors include failing to yield on entry, incorrect lane selection for exits, not signaling the intention to exit, and exiting from an inner lane by cutting across outer lanes. The IMT exam heavily scrutinizes these behaviours.
You must signal your intention to exit the roundabout by using your right indicator before reaching the exit you intend to take. This signals your manoeuvre to other road users.
The Código da Estrada establishes general principles for 'cedência de passagem' and lane discipline. Specific signage at the roundabout, such as 'Give Way' or 'Stop' signs, or directional panels, may further define priority and lane usage for that particular junction.
