Haaland, 24, was mobbed by a group of supporters as he left the Etihad Stadium behind the wheel of his luxury £250,000 Mercedes Maybach.
However, in footage that has been viewed tens of thousands of times on TikTok, Haaland appeared to have scrolled through his phone while stopped in traffic.
Accompanied by his girlfriend Isabel Haugseng Johansen, the frontman was filmed picking up the phone and briefly glancing up at a camera outside the window.
Haaland, who sported a blue hoodie, continued to brazenly check his device in the centre of the dashboard before putting it down as traffic started to move.
Manchester City striker Erling Haaland was seemingly caught on his phone behind the wheel
The incident comes just a year after he was caught using his phone while driving his Rolls-Royce Cullinan, worth £300,000, on a dual-carriageway in Manchester.
'His car was surrounded by fans taking pictures and videos. He seemed totally unfazed and didn't think anything of scrolling through his phone while driving.
'He's a role model to so many young kids - he should know better.
Just hours earlier, Haaland had scored City's first goal against Arsenal. The champions went on to secure a late point after John Stones' dramatic stoppage-time equaliser.
With the footage having gone viral, Haaland has been criticised by road safety campaigners who have branded his behaviour 'incredibly dangerous'.
Lucy Straker, Campaigns Manager at Brake, said: 'It is important for any person in a position of influence to act responsibly in these situations, so that those who look up to them can follow their example.
'Using any phone while driving is dangerous - driving is a highly complex task requiring a person's full attention, as any error can be catastrophic.
'The temptation of looking at a phone can never be worth someone's life. We are relieved that in this instance no one was hurt or killed.
Drivers caught using a mobile phone behind the wheel in the United Kingdom face being hit with a £200 fine and six points on their driving licence.
