A Perth motorist has taken distracted driving to new levels after they were filmed writing at the wheel in Midland.

Terry Doessel filmed the driver of a white SUV with a pen and notepad in hand, travelling in a 60km/h zone on Morrison Road.

Mr Doessel said he captured the footage on Monday morning while he was a passenger in another car.

“I was just talking with my wife and I noticed the white paper through the window,” Mr Doessel said.

“I am always looking for people on mobile phones and wish it was easier to report them.”

The video was uploaded to Facebook with the accompanying caption, “surely it could wait.”

A number of distracted WA drivers have been filmed posing a threat to others on the road this year, most notably a P-plater eating a bowl of cereal back in April.

The fine for distracted driving would likely incur the same penalty as using a mobile phone at the wheel - $400 and three demerit points.
