This is the most common question that many drivers ask. Anyone who has driven a vehicle has undoubtedly experienced that moment when they are going to change lanes only to see another vehicle there. This scenario could very well win the debate that there are really blind spots. There are other drivers that easily believe that they need another mirror to solve this problem.
Blind spot mirrors really help the driver achieve more visibility of the blind spots. One important reason for their function is because these mirrors see more ground compared to the mirrors installed in the vehicle. They are also positioned in a strategic way that gives the driver a better angle thereby providing him better visibility.
