Among Algeria’s many diverse customs, an intriguing local tradition is said to persist in some regions regarding road etiquette. It is alleged that when a driver honks their horn while overtaking another vehicle on the right side—an unusual maneuver given typical traffic norms—the driver being overtaken is expected to respond with a subtle gesture, commonly a flash of the headlights or a quick hand wave. This practice is not codified in formal traffic laws but appears in oral local lore and anecdotes shared by long-time residents. The tradition is believed to emphasize mutual respect and acknowledgement on the road, highlighting Algerian values of politeness and community, even in the bustling and sometimes chaotic urban traffic scenes. While not officially documented, visitors and newcomers sometimes find this tradition surprising, as it contrasts with straightforward traffic regulations elsewhere. It's worth noting that actual enforcement practices are aligned with standard traffic laws, and this custom remains part of Algeria’s rich tapestry of unwritten social norms rather than formal legal requirements.
