Why is it important to check blind spots before changing lanes?

Checking blind spots before changing lanes is crucial for ensuring road safety. Blind spots are areas around a vehicle that cannot be seen through the mirrors. When changing lanes, other vehicles, cyclists, or pedestrians may occupy these hidden areas, creating a risk of collision. By checking blind spots, drivers gain a complete awareness of their surroundings, which allows for safer lane changes.

This practice helps avoid accidents that can occur from assuming that the roadway is clear based solely on mirror visibility. Awareness of potential hazards in blind spots is essential, especially in environments with varying vehicle sizes, including smaller cars and larger trucks.

The importance of this practice extends beyond mere roadside etiquette; it is a vital aspect of defensive driving that significantly reduces the chances of accidents caused by unobserved vehicles. Recognizing this enables drivers to make informed decisions when changing lanes and enhances overall traffic safety.
