What is the primary purpose of checking blind spots before changing lanes?

The primary purpose of checking blind spots before changing lanes is to avoid obstacles that are not visible in mirrors. Even though motorcycle mirrors provide crucial information about the traffic directly behind and beside you, they often do not cover the full area adjacent to your bike, especially on either side. This area is referred to as the blind spot, and vehicles, cyclists, or pedestrians can be present in these areas without being detected by your mirrors.

By physically turning your head to check these blind spots, you ensure that you have a complete view of your surroundings before executing a lane change. This step is essential for maintaining safety on the road and preventing potential accidents. The correct choice emphasizes the importance of awareness and vigilance while riding, key factors in motorcycle safety.

While the other options may seem relevant, they do not capture the primary reason for this critical safety measure. Maneuvering a motorcycle effectively involves various factors, but checking blind spots specifically addresses the unseen risks. Determining the speed of adjacent vehicles or making lane changes quicker is secondary to ensuring a clear path when changing lanes, thus reinforcing why avoiding obstacles in blind spots is the focal point of this practice.
