You check blind spots by turning your head slightly and looking over your shoulder toward the area you can’t see in your mirrors. Mirrors show much of the road, but they can’t reveal everything, leaving certain lanes hidden from view. By briefly turning your head to scan those areas before changing lanes, you confirm the adjacent lane is truly clear and you won’t cut someone off or collide with a vehicle. Relying only on the rearview mirror can miss cars in the lanes next to you, turning the wheel toward the blind spot is unsafe and could drive you into another lane, and blinking won’t help you see what’s there. So the reliable method is to physically look to the side you plan to move into.
