Overhead signs are large signs placed above roadways to provide important information to drivers. They help guide vehicles by displaying directions, distances, and warnings about upcoming exits or hazards. These signs are often illuminated for better visibility, especially at night or in poor weather conditions. In addition to road guidance, overhead signs can also indicate speed limits and lane usage, ensuring that drivers stay safe and informed. Commonly seen on highways and busy intersections, these signs play a crucial role in traffic management and help prevent accidents by keeping drivers aware of their surroundings and upcoming changes in the road.
