What does a motorway signal indicating 'Change lane' imply?

The indication 'Change lane' on a motorway signal suggests that it may be beneficial to transition into another lane. This typically implies that there could be a more suitable lane available for travel, either for reasons of speed, safety, or flow of traffic. For instance, it could be due to obstacles, slower vehicles, or conditions ahead that may not be ideal for the current lane.

When a driver sees this signal, it prompts them to assess their surroundings and consider whether moving to another lane would improve their driving situation. The emphasis is on the potential for enhanced driving conditions, which is vital for maintaining traffic efficiency and safety on the motorway. This is particularly relevant in emergency response scenarios where timely and effective maneuvers can have significant implications.
