Traffic delays occur when vehicles cannot move as quickly as usual due to various factors. Common causes include road construction, accidents, or heavy traffic during peak hours. These delays can lead to longer travel times and increased frustration for drivers and passengers. In urban areas, traffic signals and intersections can also contribute to delays, especially when they are not synchronized properly. Weather conditions, such as rain or snow, can further exacerbate the situation, making roads slippery and reducing visibility. Understanding these factors can help drivers plan their routes more effectively.
