Sidewind, also known as crosswind or lateral wind, is a phenomenon that occurs when wind blows perpendicular to the direction of motion. This type of wind can be dangerous for vehicles, especially for high-sided ones, as it can cause instability and even lead to accidents. To avoid such situations, it is essential to understand and use the right terminology when describing such conditions. Some synonyms for the word side-wind include cross-breeze, diagonal wind, transverse wind, or flank wind. These words can help to better communicate weather forecasts and driving conditions to ensure safety on the road.
