At a controlled intersection, how can you know that another driver has seen you?

In the context of traffic interactions at controlled intersections, the best choice is that you can never know for certain if another driver has seen you. Even if you employ strategies like making eye contact, observing signals, or gauging their speed, these actions do not guarantee that the driver is aware of your presence.

Making eye contact can suggest awareness, but distractions or obstructions can prevent the driver from seeing you even if you believe the interaction has occurred. Similarly, a driver may signal their intention to turn or change lanes but may not fully notice or account for your motorcycle in their path. Observing a driver's speed may provide some context about their intent, yet it does not confirm that they are aware of your presence or capable of reacting safely.

In traffic situations, it's essential to assume that other drivers may not see you until you can clearly confirm otherwise, prioritizing caution and defensive driving. Therefore, the idea that you can never really know if another driver has seen you reflects the unpredictability and need for caution while navigating intersections.
