What is a crucial factor to consider before changing lanes?

Before changing lanes, it is essential to check mirrors and blind spots. This practice helps ensure that there are no vehicles or obstacles in the way that could lead to a collision. Mirrors provide a view of the vehicles behind and beside you, allowing you to gauge the distance and speed of other drivers. However, mirrors have limitations and may not capture areas directly adjacent to your vehicle, known as blind spots. By physically checking these areas, a driver can confirm that it is safe to change lanes without endangering themselves or others.

This component of safe driving is crucial for maintaining awareness on the road and preventing accidents, reinforcing the importance of situational awareness and vigilance when maneuvering the vehicle.
