How should you check your blind spots?

Looking over your shoulder before changing lanes is crucial for checking your blind spots because mirrors alone do not provide a complete view of the area around your vehicle. While mirrors can help you see some of the traffic surrounding you, they may not adequately capture vehicles or objects that are in the blind spots—areas to the sides or directly behind your vehicle that are not visible in the rearview or side mirrors.

By physically turning your head and looking over your shoulder, you can directly observe these blind areas and ensure that it is safe to make a lane change or maneuver. This practice enhances your situational awareness and reduces the risk of collisions caused by unseen vehicles or obstacles.
