To increase their visibility at intersections, motorcyclists should flash their headlights. This action captures the attention of other drivers, making the motorcyclist more noticeable amidst various stimuli at intersections. Increased visibility is crucial in these high-risk areas where vehicles cross paths and unexpected movements are common. Flashing headlights act as an additional non-verbal cue to alert drivers of the motorcyclist's presence, thereby reducing the risk of collisions.
