South Australian cop in charge of road safety fined over bike selfie

A South Australia Police superintendent in charge of enforcing road safety has been fined after he used a mobile phone while riding a bike.

Superintendent Shane Johnson, who heads up SA Police's Traffic Services Branch, was issued an expiation notice after taking a selfie while cycling down a back street and posting it to his Strava account.

Johnson said he had been "winding down" after a 202-kilometre ride with friends on October 18 and was less than 100 metres from his home when he took the photo.

The image, obtained by the Adelaide Advertiser, shows the superintendent wearing a helmet and smiling while holding his phone for a selfie.

Johnson shared the image to GPS tracking app Strava, which cyclists and runners regularly use to log their rides.

Under SA law, cyclists must obey the same road rules as drivers and using a mobile phone while riding a bike is considered a traffic offence.

Johnson admitted using his phone while on a bike was a "lapse in judgement".

"I take full responsibility for my actions. I acknowledge I have done the wrong thing and accept the consequences," Johnson added.

"No-one is immune from road traffic laws.

"Every road user needs to remain alert and aware of the rules when using mobile phones not just for their own safety, but that of other road users."

The incident has been referred to the to SAPOL's Ethical and Professional Standards Branch.

An internal conduct investigation remains ongoing.
