MOST speeding infractions are of drivers caught between 10 kilometres an hour and 19km/h above the speed limit, according to the RAA, prompting reminders to slow down.
This comes as the school holidays are on, leading to an increase of vehicles on regional road trips.
Police figures show, for each of the past five years, the majority of speeding motorists were travelling between 10km/h and 19km/h above the limit.
Last year more than 108,000 drivers were detected at such high speeds, representing 55 per cent of all speeding offences caught on camera or by police officers.
The police figures also show high level speeding is occurring on suburban streets and at pedestrian crossing, as well as major roads, highways and freeways, RAA Safety and Infrastructure senior manager Charles Mountain said.
"It's a great concern that tens of thousands of drivers a year are caught travelling at such excessive speeds, which can have catastrophic consequences for all road users,'' he said
"RAA is urging drivers to stick to the speed limit and arrive safely every time they get behind the wheel.
"Motorists must also be aware there will be more traffic on regional roads during the upcoming school holidays and they should allow plenty of time to arrive safely at their destination.''
Mr Mountain said at this stage the state's 2020 road toll is less than the same time last year, but tragically is higher than both 2017 and 2018 and has recorded a high percentage of rural fatalities.
He also warned drivers to guard against fatigue and distraction and said it was up to all road users to prioritise safety.
He urged motorists to ensure their vehicles were roadworthy, especially before driving holidays, including inspecting tyres, lights, windscreen wipers and spare tyres.
