What is the best way to check your blind spot?

Turning your head and looking over your shoulder is the best way to check your blind spot because it provides the most comprehensive view of the areas around your vehicle that are not visible through mirrors. Blind spots are specific zones that mirrors do not cover, making it crucial to physically turn and check these areas to ensure that it is safe to change lanes or make maneuvers.

While using the rearview mirror and side mirrors can help in assessing the surrounding traffic, they do not eliminate blind spots. Relying solely on these mirrors can leave certain areas unchecked, potentially leading to accidents. Similarly, while vehicle sensors can assist in monitoring the environment, they can sometimes give false readings or miss objects that are nearby. Hence, the most reliable method remains the physical act of turning your head to gain a clear visual understanding of your surroundings.
