What is the proper way to change lanes?

Answer: B — Signal, check mirrors and blind spots, and then change lanes when safe

The proper way to change lanes involves a sequence of important safety steps to ensure that the maneuver is executed safely and without impacting other road users. Signaling is the first step because it alerts other drivers of your intention to change lanes, which is essential in maintaining safe driving conditions. Next, checking mirrors provides you with information about the traffic situation around you. However, mirrors alone cannot provide a complete picture, especially regarding vehicles in blind spots. That is why checking blind spots, which involves turning your head to look over your shoulder, is also crucial. This step helps to ensure that there are no vehicles or obstacles in the lane you wish to move into, which could lead to accidents if overlooked. Only after signaling and thoroughly checking both mirrors and blind spots should you proceed to change lanes, and only when it is safe to do so. This method minimizes potential risks and promotes a safer driving environment for everyone on the road.
