The truck driver behind the wheel of a prime mover that collided with a Loreto school bus on the Western Freeway has applied for leave to appeal his prison sentence, which exceeds 12 years. The crash, which occurred near Bacchus Marsh, involved a school bus carrying students when it was struck from behind, leading to serious consequences and a major investigation. The driver is now arguing the sentence imposed is excessive, with the matter set to be reviewed by the court as part of the appeals process.
