While driving on an expressway in extreme fog, what should you look for?

When driving on an expressway in extreme fog, it is crucial to be aware of your surroundings and make safe decisions. Looking for the closest exit is particularly important in such conditions because visibility can be severely reduced, making it difficult to see other vehicles, road signs, or potential hazards. Identifying the nearest exit allows you to plan a safe route off the expressway, where you can wait for conditions to improve or find a safer environment.

While headlights from oncoming vehicles, emergency flashers, and potential hazards on the roadway can also be important considerations, focusing on the closest exit provides a clear course of action. This approach prioritizes your safety and helps avoid the risks associated with remaining on a busy or unclear expressway when visibility is compromised.
