The bus came off a snowy road in Motala in central Sweden while it was taking pupils to school in what was one of several accidents to happen during the morning rush hour.
Around 20 pupils were travelling on the bus when it spun off a road as it turned a corner and landed on its side in a ditch.
Two children, both aged 12, were taken to hospital, but emergency services reported that neither had been seriously injured.
Police said they were investigating exactly what had caused the bus to come off the Karlsbyvägen road, but noted that there had been a number of accidents in the region, apparently caused by heavy snowfall and ice.

Marie Staerk, a forecaster at Sweden's weather agency SMHI told the TT newswire that there had been upwards of 20cm of snow in some parts of Svealand and Götaland on Monday morning.
She warned that more snow could fall during the day, turning into sleet by the evening and forming ice overnight as temperatures drop below freezing again.
"Then it [the snow] may freeze and again it may become cumbersome in traffic," she said.
