Traffic and Highway Patrol Command is reminding motorists of the need to take extra care during morning and afternoon school hours.

Police perform regular patrols around school zones and already this year have caught 27 people speeding and causing other offences in school zones in Dubbo.

During the 2013-14 financial year, that number jumps to 89.

"With parents, children, teachers and support staff moving in and around schools during peak times, motorists need to be fully aware of the 40km/h speed limits in force," Acting Assistant Commissioner Stuart Smith said.

"Recent incidents involving collisions and children crossing the road highlight the need to maintain the 40km/h speed limits, in order to be able to react to an unexpected event if needed."

This year 5328 infringements have been issued for speeding, parking, and other offences in school zones across NSW.

This compares to 10,750 infringements in total for 2013, and 10,515 in total for 2012.

While Police say incidents in Dubbo are still too common, the city doesn't appear in the top 10 areas for school zone infringements issued by police.

Auburn tops the list with 227, while the others include: Kingsgrove (155), Minto (142), Bathurst (101), Singleton (94), Condell Park (94), New Lambton (92), Lawson (80), Caringbah (78) and Surry Hills (74).

"Traffic and Highway Patrol Officers will continue to focus on speed, parking, and school crossing enforcement to ensure that our kids are safe when going to, or coming from school," Acting Assistant Commissioner Smith said.

Margaret Prendergast, General Manager of the NSW Centre for Road Safety, is urging parents to plan the trip to school.

"Always hold your child's hand while crossing the road up until the age of ten. Children need your help to spot danger like vehicles coming out of driveways.

They can also be easily distracted and wander into traffic.

"Drop off and pick up your child near the school gate and avoid calling them from across the road.

Ms Prendergast also urged parents to talk to their children about 'Stopping, Looking, Listening and Thinking' every time they cross the road.
