Icy conditions are causing havoc on Victorian roads as the big chill settles across central Victoria.
After more near-zero temperatures this morning, rain and sleet have turned into black ice on many roads, making them treacherous hazards.
In the worst reported incident, ice is being blamed for a huge herbicide spill after a truck rolled on black ice on the Calder Alternative Road at Lockwood about 3.45am.
The truck was carrying 64 20-litre drums of weed killer, many of which have now spilled causing emergency services to close the road in both directions.
A CFA spokeswoman said specialists from the Environment Protection Agency and 20 firefighters wearing splash suits were attempting a “recovery proceedure”.
“They are using over-sized drums to take away the broken drums,” said the spokeswoman.
The male truck driver has been taken to hospital.
