The best way to increase your chances of being seen at an intersection is to:

Riding in the center portion of the lane with your lights on is an effective strategy to enhance visibility at intersections. This position allows you to be more easily seen by other drivers, as it places you in a spot where you can attract attention more effectively, given that many vehicles typically look toward the center of their lane. Additionally, having your lights on increases your visibility, even during the day, making it far less likely for other road users to overlook you. This combination of positioning and lighting is crucial in preventing accidents, especially in busy and potentially hazardous areas like intersections.

Riding in the right portion of the lane may put you in a position where you could be in a driver's blind spot, while opting to stay at the far side of the lane could make it more difficult for oncoming vehicles to notice you. Slowing down and waving might attract attention, but it does not necessarily improve your visibility or positioning in a way that enhances safety.
