The driver, a 28-year-old man who was known to police for committing minor offences, was arrested at the scene, polices sources said.
Unconfirmed reports have claimed the driver suffered from major psychological problems.
The crash is believed to have taken place in front of Saint-Exupery high school in the suburb of Blagnac.
The Mayor of Toulouse, Jean-Luc Moudenc took to Twitter and said: "Very shocked by the aggression against the students in Blagnac. We offer them and their families all of our support"
