PCV CPC Case Study 64

-->
Liam, an experienced coach driver, has been introduced to driving modern minibuses equipped with auxiliary air systems and power-assisted steering (PAS). He needs to adapt his driving skills to these new features, understanding how they influence vehicle control and safety. Liam must be particularly aware of the operational aspects of PAS, including its dependency on the engine running and the increased effort required in steering if it fails. Additionally, he needs to comprehend the safety measures, such as air-operated accelerators being disabled when doors are open.

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.
