Northern Roads and Public Order Safety Sergeant Nick Clark said tomorrow would be the focus day of the campaign in the North. 

Police will be targeting drink and drug-driving along with speeding and parking offences around school areas.

``These operations can be run any time of the day and can target any group of people,'' Sergeant Clark said.

```The main thing for parents to do with children is if the school has designated crossings or traffic lights nearby use them.

``Be aware there's going to be large volumes of traffic in and around schools being the first day back.''

Sergeant Clark said traffic incidents near schools were an intermittent problem, however, some schools had ``taken very proactive roles and assisted greatly with controlling movements''.

``Just take care around schools, there's going to be a lot of kids back from their school holidays (and) a lot of extra traffic and pedestrian traffic on the roadways,'' he said. 

Don't go faster than 40 km/h when you pass a school zone sign on official schooldays during the times on the sign. 

Don't go faster than 40 km/h within 50 metres of a bus with a school bus warning sign and lights. This includes driving behind or towards a bus.
