The driver, a 43-year-old Castlemaine man, was unhurt and ambulance units were turned away after initially being called.

The truck and trailer were travelling south along Ballan-Daylesford Road, near Bunding, when it lost traction and jack-knifed.

Two heavy-haulage tow trucks righted the truck before towing it away just before midday.

A front-end loader and a forklift assisted in clearing away concrete tiles, pallets and other debris which was scattered across the road.

Four police units set up road blocks at the Western Freeway turnoff and at the north end of the crash on Ballan-Daylesford Road.

Ballan’s Senior Constable Mark Dunne said emergency services were called to the scene after 6.30am.

“The vehicle has lost traction and the vehicle has overturned and jack-knifed,” Senior Constable Dunne said.

He said speed did not appear to have been an issue in the crash, however the incident was still being investigated.

He said the incident served as a timely reminder to drivers to be wary of road conditions.

“It’s a warning to all drivers to be aware of road conditions, particularly due to climatic conditions at this time of year,” he said.

The mercury plummeted to a low of minus 4.6 degrees at 4.22am and was at minus 3.6 degrees at 6.30am – about the same time as the crash.

The accident comes after dozens of motorists slid off roads in the region at the weekend due to black ice.

Emergency services scrambled across Ballarat on Saturday morning after 26 accidents were reported.

Ballarat was dusted with snow and experienced its coldest day in 20 years on Friday, prompting emergency services to warn motorists of black ice.
