When is it important to check blind spots?

Checking blind spots is crucial before changing lanes or merging because these actions require you to be fully aware of your surroundings. Blind spots are areas around your vehicle that are not visible through your mirrors, and other vehicles or obstacles may occupy these zones without your knowledge. Therefore, by turning your head and checking these blind spots, you ensure that the lane is clear of any vehicles, cyclists, or pedestrians that might not be visible using mirrors alone.

Failing to check blind spots can lead to collisions, as merging or changing lanes without ensuring that it is safe can put others at risk. It's a proactive safety measure that every driver should incorporate into their routine, not just during specific situations or intervals. Understanding this helps reinforce the importance of comprehensive situational awareness at all times while driving, rather than relying on assumptions based on mirror visibility alone.
