Priority signs
A priority sign is a traffic sign that indicates the order in which vehicles shall pass intersection points. Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes. The general principle that establishes who has the right to go first is called 'right of way' or 'priority'. It establishes who has the right to use the conflicting part of the road and who has to wait until the other does so. The vehicle that does not need to wait is said to 'have the right of way' or to 'have priority.'

Must you always stop when giving way in Brazil?
No. A give-way control requires stopping when necessary to yield or obtain a safe view. A stop sign requires a complete stop even if the road appears empty.
