The spokesman, whose identity was not released, said the woman was fined $91 after police officers spotted her allegedly flossing her teeth and looking in her vehicle's rear view mirror, all while she was speeding along on the M4 motorway, The Sun said Saturday.
"We've caught women applying lipstick and makeup and men using an electric razor on their way to work," the spokesman said of the recent incident.
"But this is the first time we've seen someone flossing their teeth. It's particularly dangerous because you need to use both hands."
The Sun said after being stopped near Newport, South Wales, the female driver also received a stern warning about careless driving from the officers.
