In low visibility conditions, it is crucial to be aware of what cannot be seen in your mirrors because limited visibility can significantly increase the risk of not noticing other vehicles or obstacles nearby. When visibility is compromised, such as in fog, heavy rain, or during nighttime driving, it's easy to overlook vehicles that may be in your blind spots. This could lead to dangerous situations, such as collisions when changing lanes or merging. Therefore, making a conscious effort to check mirrors more frequently and understanding the limitations of visibility can help maintain safety on the road.

Other aspects, such as adjusting speed, recognizing traffic light colors, or noting road signs, are also important, but the priority should be on ensuring that you are aware of your surroundings, particularly those things that may not be readily visible to you.
