Systems and methods are provided for processing notifications regarding issues with nearby vehicles. A roadside reporter receives notifications from individuals or computing devices reporting problems or violations associated with nearby vehicles, and the notification for uniqueness and authenticity. Upon determining that the notification is unique and authentic, the roadside reporter system notifies the driver of the nearby vehicle and other relevant parties about the problem or violation. The roadside reporter may issue rewards to the reporting user. The roadside reporter system further allows the driver of the nearby vehicle to respond to the notification, and subsequently provides the driver with incentives to address the problem or violation.
