What is the correct way to initialize a lane change?

The correct approach to initiating a lane change involves multiple critical steps that ensure safety and compliance with driving regulations. First, it is essential to check your mirrors to understand the positions of vehicles around you. This includes checking the side mirrors and the rearview mirror to gauge both your immediate surroundings and the overall traffic situation.

Next, checking your blind spots is crucial because there may be vehicles that are not visible in your mirrors. These blind spots are areas to the side and rear of your vehicle where other vehicles may linger, and failing to check these areas before changing lanes can lead to collisions.

Finally, signaling your intent to change lanes is necessary to communicate with other drivers. Proper signaling lets those around you know your intentions, allowing them to react accordingly. This sequence of checking mirrors, checking blind spots, and then signaling creates a safe protocol for changing lanes.

The other options do not adequately cover the necessary steps or prioritize safety. For instance, signaling and changing lanes immediately skips vital checks, which can endanger yourself and others. Simply checking the rearview mirror or only one type of check does not provide the comprehensive awareness needed before making a lane change.
