A 25-year-old man received non life-threatening injuries when a tractor he was operating while spreading fertiliser overturned on a steep ridge along the Brucknell Road near Timboon about 11.30am.

It is understood he was working for a contractor and the tractor rolled about 80 metres down a slope.

The driver was taken to Warrnambool Base Hospital with lacerations to a leg and possible head and neck injuries.

A car also rolled over on the Cobden-Lavers Hill Road near Gribbles Road at Jancourt and at Woorndoo a truck collided with a pole. Mortlake and Lake Bolac police attended the accident scene.

Warrnambool police Senior Sergeant Russell Tharle reminded all motorists to be aware and drive to the road conditions.

"If it's a windy, rainy day motorists need to alter their driving behaviour accordingly," he said.

"We haven't had much rain recently and today's downpour mixed with oil on the road has led to the road surfaces being slippery.

"At this time of year drivers should check the inflation and tread of their tyres, ensure that windscreen wipers front and rear are working effectively and check your demister."
