What is the recommended action when you need to change lanes on the highway?

The recommended action when changing lanes on the highway is to signal, look around, and check mirrors. This approach emphasizes the importance of safety and awareness in driving. When changing lanes, signaling alerts other drivers of your intentions, which can help prevent accidents. Looking around involves checking your blind spots and being aware of the surrounding traffic before making the move, ensuring that there is enough space to change lanes safely. Additionally, checking mirrors provides a clear view of vehicles that may be approaching from behind or alongside you. This multi-step process helps ensure that the lane change is executed safely and responsibly, reducing the risk of collisions or misunderstandings with other drivers.
