What is the correct action to take during a lane change?

The correct action to take during a lane change involves signaling your intention, checking your mirrors, and examining your blind spots before moving into the adjacent lane. This combination is essential for ensuring the safety of both the driver making the lane change and other road users.

Signaling alerts other drivers of your intention to change lanes, allowing them to adjust their speed or position if necessary. Checking mirrors provides a quick reference of the vehicles in adjacent lanes and helps ensure there are no vehicles in your immediate vicinity that could pose a danger. Most importantly, examining blind spots is crucial because mirrors do not always provide a complete picture of surrounding traffic; some vehicles may be in areas that are not visible in standard mirrors.

Focusing solely on any single item in this process, such as changing lanes without checking surroundings or only signaling once already in the new lane, would likely lead to hazardous situations. Each step plays a vital role in a safe and effective lane-change maneuver, emphasizing the importance of thorough awareness of one's environment.
