Jovanna Penn-Reina waited, frightened and injured, for firefighters to cut her from the car in which she was a passenger.
She could see her friend Caleb Jackson slumped in the front seat, and thought he was probably dead.
"It felt like I was stuck there for ages. I was really frightened and couldn't stop crying," she said.
Jovanna and Caleb, with fellow Cullinane School students Pita Phillips and Tobias Todd, were the actors in a mock crash organised by Students Against Drink Driving (SADD).
The mock crash involved a driver, with three passengers in the car, being distracted by talking on a cellphone. The car hit a tree in the Jubilee Stadium carpark, killing the front seat passenger and trapping the injured backseat passengers.
