A woman's startling phone use on the freeway serves as a warning against dangerous driving this long weekend.
The 32 year old has been fined $400 and penalised 3 demerit points for an incident which is notching up the views online.
Another driver filmed the woman using her phone while travelling at 100kph on the Mitchell Freeway through Leederville.
She only stopped when another driver honked their horn to get her attention.
The footage is doing the rounds on Facebook and has already been viewed more than 100,000 times since Sunday.
With double demerits coming into force at midnight tonight, it's a timely reminder to put the phones down and keep your eyes on the road.
