PCV CPC Case Study 65

-->
Rachel, a bus driver transitioning to a fleet of modern buses, must adapt to vehicles equipped with auxiliary air systems and power-assisted steering (PAS). She is learning how these advanced systems affect the driving experience, especially the need for less effort in steering due to PAS. Rachel also needs to understand the safety features, such as the disabling of air-operated accelerators when the doors are open, and how to manage situations like a PAS failure, which requires significantly more effort to steer.

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.
