How can you check your blind spot when driving?

Checking your blind spot is crucial for safe driving, especially when changing lanes or merging. The safest and most effective way to ensure there are no vehicles or obstacles in your blind spot is by turning your head and looking over your shoulder. This action physically exposes you to the area that your mirrors might not capture, allowing you to make a more informed decision about your surroundings.

Using only mirrors is not sufficient because mirrors can create blind spots due to their angles and limitations. Relying solely on glancing at the dashboard does not give visibility to the areas around you that mirrors may miss. Assuming that no one is in your blind spot can lead to dangerous situations, as it leaves you unaware of nearby vehicles or cyclists that could be present. Thus, turning your head and checking your blind spot is the most reliable method for maintaining safety while driving.
