What might happen if you do not perform a blind spot check before changing lanes?

Performing a blind spot check before changing lanes is critical for ensuring the safety of all road users. If you neglect this important step, there is a significant risk that you could collide with another vehicle that is occupying your blind spot. Blind spots are areas around your vehicle that you cannot see directly through your mirrors, and assuming these areas are clear without checking can lead to dangerous situations. Other vehicles, including motorcycles or smaller cars, might be in your blind spot and not visible in your mirrors, increasing the chance of an accident if you proceed to change lanes without confirming their absence. This underscores the importance of being vigilant and checking blind spots to prevent collisions.
