Many students will return to school on Tuesday after pupil free days on Monday however police urge motorists to slow down regardless, also saying there will be a strong presence across public transport networks as well.

Some schools may not have pupil free days to start the week and teachers will be working, with school zones active between 8am and 9.30am in the morning, and 2.30pm and 4pm in the afternoon.

It's far from a polite request from police, abiding by those speed limits in those areas is an expectation.

"Everyone knows of the 40km/h limit in school zones, which have been in place for many years, and it's our expectation people comply with it and other safety requirements," Traffic and Highway Patrol Commander, Assistant Commissioner Karen Webb said.

She said police won't just be targeting speeding, they'll also continue to focus on other dangerous driving behaviours as well like double parking or using mobile phones while driving in those school zones, with students' safety the priority.

Commander of Police Transport Command North/Central Sector, Detective Acting Superintendent Todd Cunningham, echoed those sentiments, calling on the public to report those behaviours if they see them as well.

"We want everyone to arrive at their destination safely as students go back to school," he said.

"Police are here to help so if you see any suspiciuous activity, anti-social behaviour or crime please report it to Crime Stoppers or (call) triple zero if it's an emergency."

Drivers wanting additional reminders of the speed limit can also download the Speed Advisor App, which provides audio alerts about speed limit changes, including when you enter a school zone, or if you are speeding.
