In Argentina, many highways and roads often pass through construction zones due to expansions, repairs, or maintenance of road surfaces and other roadway elements. This requires the presence of specific warning signs, particularly those with an orange background and black letters or symbols, which inform drivers about changes in lane configuration. It is crucial for both local and visiting drivers to understand these signals, as they are part of the necessary knowledge for obtaining a driving license and ensure safety on the roads.

The article emphasizes the color coding of traffic signals, where orange signals specifically alert drivers to work zones, indicating a need for caution. Other colors serve different purposes; for instance, red is used for stop and yield signs, while yellow warns of hazards. Understanding these signals helps prevent accidents and maintain a smooth flow of traffic, especially in areas under construction where changes are frequent.

Moreover, the LANE SHIFT signal is not just a warning for existing conditions but also plays a role in managing traffic behavior. When drivers observe these signals, they are prompted to adjust their lane position, which if not done smoothly can lead to sudden braking or erratic driving, thereby contributing to congestion. Thus, it becomes essential to respect these signals to minimize delays and ensure safety on the roads, especially in high-traffic regions where construction is ongoing.
