How do you check your blind spots before changing lanes?

Turning your head to look over your shoulder is the most effective way to check your blind spots before changing lanes. This action allows you to visually confirm that there are no vehicles, cyclists, or pedestrians in your blind spots, which are areas not visible through your mirrors. While mirrors can help you see a large portion of your surrounding area, they do not cover the entire field of view, particularly the areas directly beside and slightly behind your vehicle. By looking over your shoulder, you gain a comprehensive understanding of your surroundings, ensuring that it is safe to change lanes. This practice is a crucial component of safe driving and is often emphasized in driver education to prevent accidents caused by blind spot misjudgments.
