Speed bumpBrazil
3. Speed bump
A speed bump is a raised traffic-calming device placed across all or part of a road to make drivers reduce their speed. It is commonly used near homes, schools, crossings, parking areas and other places where low vehicle speeds are important.
Speed bumps vary in shape, height and legal status. Drivers should approach them at a low, controlled speed and follow any warning signs or speed limits that apply.

How should I recognise and approach a speed bump in Brazil?
Brazil’s Traffic Code addresses ondulações transversais, commonly called lombadas, as physical speed-reduction devices subject to the national traffic authority’s criteria. Distinguish one from a raised pedestrian crossing.

Which speed should I use at a raised device in Brazil?
Read the accompanying speed restriction and reduce speed before the device. A numerical limit is a maximum; the height, profile, visibility and presence of pedestrians can require a slower approach.

Does a raised road surface give pedestrians priority in Brazil?
A raised device alone does not identify pedestrian priority. If it incorporates a crossing, apply the crossing’s controls and the national rules. Pedestrians on a marked crossing have priority, subject to signal-controlled rules. If the signal changes before they finish, let them complete the crossing. At an unsignalised junction, pedestrians already crossing also have priority.
