Toronto police were out Tuesday to ensure that drivers are obeying the 40 kilometres-per-hour speed limit around schools now that children are back in class -- and that includes school buses.

"Unfortunately we had a school bus that was actually going to service the school just down the street from us," Sgt. Tim Burrows of the Toronto Police Services' traffic unit said Tuesday from a radar site near Don Mills Road and Eglinton Avenue East.

Officers clocked the bus going at 51 kilometres per hour in the school zone, he said.

But that driver wasn't the only speeder. An officer told another driver she was caught driving 63 km/h in the zone.

"We're seeing speeding in the school zones. Illegal parked vehicles, people not obeying the crossing guard's stop sign," Burrows said. "All of these things contravene safety."

In a two-hour period this morning, traffic officers handed out 25 tickets.

The safety blitz is scheduled to continue until Sept. 17.

In posts to his account on Twitter, the social messaging service, Burrows reminded parents and children to stop, look and listen before they crossed the street.

"Use your eyes and your ears before you move your feet. ~Elmer the Safety Elephant," he wrote.
