Meanwhile motorists are being warned to watch out for icy conditions on roads, with frosty conditions expected through the week and a spate of ice-related crashes over the weekend.
Seven crashes on the Mamakus in the space of just two hours are being blamed on frosty conditions, according to Mrs Jones.
She said the road south of the Fitzgerald Glade proved problematic for drivers between 7am and 9.30am on Saturday morning. None of the seven crashes resulted in serious injuries.
With overnight temperatures expected to be 0C or below for the rest of the week, Mrs Jones said drivers needed to use common sense and slow down when driving.
She said people travelling early on cold mornings needed to expect ice. Quieter roads were at more risk of ice because there was more of a chance for ice to settle, she said.
