The near-accident involving youngsters from Heverlee and Antwerp nearly happened at 6AM last Sunday. The children's parents intend to file a complaint.
One of the parents told VRT News: "It was dreadful. For several moments the children thought they were going to die."
The parents are also upset by the lack of communication.
"We as parents weren't told a thing, while the company should have informed us extensively."
The teenagers all received an email, though some were shocked because it did not contain any apologies. A spokesman for the travel firm explained that the drivers switched places at the next car park.
