The accused, a municipal bus driver, was charged with dangerous driving causing death after her bus rammed into a line of stopped cars at full speed, killing one driver.
The Crown relied on Engine Control Module (ECM) data showing the accelerator was fully depressed and brakes were not applied until seconds after impact.
The defence argued the brakes failed and challenged the ECM's reliability, pointing to a botched police inspection and the unexplained destruction of the bus before trial.
The court admitted the accused's spontaneous utterances at the scene that the brakes failed.
Finding that the Crown failed to exclude the reasonable possibility of mechanical failure, the court acquitted the accused.
