PCV CPC Case Study 62

-->
James, a seasoned bus driver, has recently started driving a newer model equipped with both auxiliary air systems and power-assisted steering (PAS). He must adjust to the differences in handling and control compared to older buses he previously drove. James needs to understand how the air-operated systems function and their interlinking with safety features, like the disabling of accelerators when doors are open. Additionally, he must be aware of the operational nuances of PAS and the necessary actions in case of a system failure.

There are 7 multiple choice questions in this PCV CPC case study. Read this carefully and ensure you fully understand the scenario before starting the test. You need to score 6 out of 7 to pass.
