How often should you check your blind spots while driving?

The correct choice emphasizes the importance of being aware of your surroundings, especially when changing lanes or merging. Checking your blind spots before executing these maneuvers is crucial for ensuring that no vehicles or cyclists are in those areas that are not visible in your mirrors. This practice helps you avoid potential collisions and contributes to safer driving, as you are actively monitoring the positions of other road users.

While other situations like checking at intersections or monitoring regularly could be important, they do not specifically focus on the critical moments when lane changes and merges occur. Such actions are high-risk, and ensuring you have a clear understanding of what's in your blind spots can make a significant difference in the safety of both yourself and others on the road.
