So far automatic black ice indicators have been turned on eight times this winter on the Midland Highway between Blampied and Daylesford.

Regional director Ewen Nevett warned motorists not to rely on the automatic indicators and to remain cautious during the cold snap.

“As we find ourselves in the middle of another cold winter, I urge drivers to be extra vigilant of black ice on our region’s roads,” Mr Nevett said.

“The cold weather we’re known for in the Central Highlands means black ice is a serious problem, one which can have terrible consequences if drivers don’t use the roads carefully. “

The black ice warning system uses sensors to automatically detect black ice before it forms.

Amber flashing signs should then switch on and the information sent to VicTraffic app and website.

The traffic management centre is also able to switch on the warning signs if notified by the public.

Mr Nevett said drivers should slow down to the recommended 40 kilometres per hour when confronted with icy roads.

“Drivers need to be responsible when they are behind the wheel and aware of the conditions they are travelling in,” Mr Nevett said. 

“Sub-zero temperatures combined with overnight rainfall in the region gave a strong indication that black ice would form.

“Drivers need to be vigilant before taking to the roads on mornings like we saw today.”

Drivers are urged to check the latest weather conditions; check the VicTraffic app; delay travelling in poor conditions when possible; and to slow down to a safe speed.
