What does the orange sign on the motorway indicate?

The orange sign on the motorway is specifically designed to guide drivers to the nearest emergency phone. This is an important feature for enhancing safety on motorways, as it allows motorists to quickly locate a means of communication in case of an emergency, such as a breakdown or accident. The visibility and distinctive color of the orange sign help ensure it can be easily spotted even from a distance, allowing drivers to act promptly in urgent situations. Emergency phones are typically placed along motorways at regular intervals, providing essential support for highway safety.

The other options do not align with the function of the orange sign. While direction signs to service areas, lane usage restrictions, and speed limits are crucial aspects of road signage, they are represented by different color codes and symbols that convey those specific meanings to drivers.
