Three Port Lincoln teenagers seriously injured in a crash involving a stolen car on Monday night are expected to face charges.
The boys, two aged 13 and one aged 15, sped past a police car on St Andrews Terrace in a blue Mazda at about 9.45pm.
Police attempted to stop the car, which did not have any tail lights, but it sped off and collided with a silver Ford Ranger at the intersection of St Andrews Terrace and Stevenson Street.
The youths were taken to hospital but the occupants of the Ford escaped without serious injury.
Police checks revealed the Mazda had been stolen from Pine Freezers Road.
