What should be done before changing lanes?

Before changing lanes, it is essential to check mirrors and blind spots, and signal your intention to ensure the safety of all road users. This procedure helps in making an informed decision regarding the lane change. Checking mirrors allows you to see vehicles that may be alongside you or coming up behind you, while checking blind spots ensures that you are aware of any vehicles that may not be visible in your mirrors. Signaling your intention alerts other drivers of your planned maneuver, which enhances overall safety and helps avoid collisions. This thorough approach is a fundamental aspect of responsible driving and is critical for maintaining safe road conditions.

Accelerating quickly is not advisable, as it increases the risk of an accident and can surprise other road users. Simply asking passengers if it's safe does not provide the necessary awareness of your surroundings and places too much reliance on them. Additionally, checking only one mirror does not give you a complete view of your surrounding area, leaving potential hazards unrecognized. Therefore, a methodical and comprehensive approach is crucial in safely changing lanes.
