Speed cameras in Prince George's County will stop issuing warnings and begin sending out actual tickets starting Wednesday.

County police said the end of the 30-day warning period for the county's new automated speed enforcement program means any driver going more than 12 mph over the speed limit in a school zone could receive a $40 ticket.

The cameras will remain in operation between 6 a.m. and 8 p.m. Monday-Friday in designated school zones.
