What should you do before changing lanes?

Before changing lanes, it's essential to ensure your safety and the safety of others on the road. The correct action involves checking your mirrors and blind spots as well as signaling your intention to change lanes. Checking the mirrors allows you to see vehicles or obstacles behind and to the sides of you, while assessing blind spots is crucial for detecting any vehicles that may not be visible in your mirrors, such as those right next to you or slightly behind.

Signaling your intention is important for communicating with other drivers. It alerts them that you plan to change lanes, giving them the opportunity to adjust their speed or position accordingly. Failing to signal can potentially lead to accidents, as other drivers may not be aware of your movements.

This combination of checking mirrors, checking blind spots, and signaling creates a comprehensive strategy for safe lane changing, helping to minimize risks on the road.
