Reminder for drivers that as children head back to school in Nassau County so too, will the speed cameras in school zones.
Officials say speed cams will be fully operational at 25 locations this week.
That will more than double eventually.
Drivers caught speeding in school zones will be fined $80 for a first offense.
The cameras were first installed in July, but all 40,000 speeding tickets were dismissed after county officials discovered about a quarter of them were generated incorrectly.
