Prosecutors in the northern city of Bruges said they had opened a triple murder investigation but refused to comment on whether the mother was suspected.
"She has not been officially questioned yet and the investigating judge does not want to say anything at this stage," prosecutor's spokesperson Yves Segaert said.
Belgian media reported that the 30-year-old mother, a nurse, was taken to hospital after deliberately driving her car into a motorway bridge pillar around 10 km (six miles) from the family home near Bruges in the early hours of Wednesday morning.
