What does the term "passenger compartment" include?

The term "passenger compartment" refers to all areas accessible to occupants within the vehicle. This includes not just the front seats, but also the back seats and any additional seating areas that are designed for passenger use. It encompasses the space where passengers can sit, as well as any areas where they can store personal items, interact, and be comfortable during transit.

Understanding the passenger compartment in this way is vital for several reasons, including safety assessments, accident investigations, and vehicle inspections. Recognizing this space helps in determining where passengers are located and what potential risks they might face in the event of a collision. Additionally, it aids in understanding vehicle design and functionality from a user perspective, ensuring that all accessible areas intended for passenger use are included in assessments or regulatory compliance checks.
