The driver who crashed into the truck had just fled from the police following refusing to stop for a check.
The accident then forced the driver to continue his run to shake off the police and will be arrested later. At the same time, the 4 other people also present in the car tried to flee in turn. Except for the driver’s mother, who stayed around waiting for the police to chase the four passengers. She therefore waited for them to leave to pick up her packet of fries bought earlier.
Of course she was arrested.
