What should be checked during a pre-trip inspection?

During a pre-trip inspection, it is essential to check both tire pressure and brake functionality. These components are critical to the safe operation of any passenger vehicle. Proper tire pressure ensures that the vehicle has adequate traction, stability, and optimal fuel efficiency. Additionally, inspecting brakes is crucial because they are the primary system for stopping the vehicle safely. Ensuring that both tires are properly inflated and that the braking system is functioning well can prevent accidents and maintain passenger safety.

In the context of the other options, checking only the fuel levels or focusing only on the engine condition overlooks the importance of key safety features that can directly impact the vehicle's performance. Passenger seating arrangements, while important for comfort and safety in a passenger vehicle, do not address the immediate mechanical issues that could arise during operation. Thus, the combination of checking tire pressure and brakes is prioritized in a pre-trip inspection to ensure the overall safety and readiness of the vehicle.
