As backpack-laden students hike down sidewalks and catch buses for the start of the new school year on Tuesday, the police will be working to ensure that drivers are aware that school is back in session.

In Toronto, officers will be zeroing in on problems on roads, crosswalks in the areas in and around schools.

And it's not just problem drivers who will find themselves in police crosshairs, as officers will also be focusing on cyclists and pedestrians who aren't doing what they should be at intersections, crosswalks and the places in between.

"Enforcement will also be targeting aggressive driving offences, prohibited turns and distracted driving behaviours," police said in a news release issued Monday.

"The goal is to remind drivers that students and kids are travelling to school and it's important to stay extra vigilant this time of year," reported CBC Toronto's Neil Herland on Tuesday morning.

One year ago a 14-year-old high school student named Violet Liang died on the first day of class after she was struck by a dump truck. The C.W. Jefferys student was hit at an intersection near Finch Avenue West and Keele Street.

"The bottom line for anyone this morning: slow down, and keep your eye on the road," Herland reported.

A similar blitz will be taking place in Peel Region, where police warn they will have "zero tolerance" for drivers causing problems in school zones.  

Nearly 250,000 students are enrolled in public elementary and secondary schools in Toronto. And another 90,000-plus students attend Catholic schools in the city.
