A warning period began Monday for new red light enforcement cameras in Southwest Philadelphia.
The cameras are set up at the intersection of 58th Street and Baltimore Avenue.

The Philadelphia Parking Authority says the warning period lasts from now until February 12.
After that, anyone caught running the red light will be fined $100.
Red light cameras are currently operating at more than 30 intersections across Philadelphia.
The PPA says they have helped cut red light running by nearly 60 percent.
