Perth traffic: Heavy fog prompts extreme caution warning for motorists with low visibility on major highways

Heavy fog has blanketed Perth, triggering warnings for motorists on their morning commute.

Eerie photographs show the CBD all-but covered in fog, with only the tallest buildings visible in the haze.

And Main Roads has warned some of the city’s major highways are particularly dangerous in such conditions.

Drivers taking Tonkin Highway between Brand Highway and Great Eastern Highway have been warned to drive carefully, as well as those using Graham Farmer Freeway near East Parade.

Northern parts of Perth and the Swan Valley area are some of the worst hit locations.

Main Roads WA issued an alert Thursday morning warning of “heavy fog” and urging motorists to drive to the conditions.

Due to reduced visibility, drivers are encouraged to switch their headlights on, ensure they keep a safe braking distance.

Drivers should also allow additional travel time to reach their destination.
