A new hit-and-run alert system is taking effect today.

The system is named after Jean-Paul Guerreo, also known as DJ Jinx Paul, who was struck and killed in a hit-and-run in Brooklyn nearly a year ago.

Under the new law, alerts will go out to the public within 24 hours of a hit-and-run accident involving a fatality or serious injury.

The alert will include information about the vehicle police are searching for.

Officials say New York City averages at least one hit-and-run per week.
