HALF a dozen cars spun out of control on the Western Freeway near Ballan last night, leaving police frustrated at drivers who did not adjust to weather conditions.
Six cars lost control on a notoriously hazardous section of the highway, stopped only by roadside fences and a large pool of water that had formed on the median strip between roads.
Nobody was injured, but police say the incidents made the dangerous conditions even more hazardous.
In torrential rain between 5pm and 8pm, tow trucks were forced to park partly on the road as they worked to free the cars, making the stretch even more dangerous.
Ballan Police Leading Senior Constable Ian Watson said in heavy rain, such as what occurred last night and is forecast again today, drivers had to start driving to the conditions.
Although the speed limit on the Western Freeway is 110km/h, he said it did not necessarily mean motorists had to travel at that speed.
"If they drove to the conditions we wouldn't have these incidents and the roads would be a lot safer," said Leading Senior Constable Watson.
