California lawmakers are pushing for a new statewide alert system that would help track down hit-and-run drivers. The bill calls for the creation of a "yellow alert" system, which would be similar to the current AMBER-Alert system used for missing or kidnapped children. 

Under the proposal, digital highway billboards would display the license plate and vehicle information of any cars involved in serious or fatal hit-and-run accidents throughout California. Supporters say the Golden State is dealing with an epidemic of hit-and-runs.
