What should be checked during a pre-trip vehicle inspection?

During a pre-trip vehicle inspection, it is essential to maintain a comprehensive routine that covers various critical components of the vehicle to ensure safety and operational efficiency. The correct answer emphasizes the importance of checking lights, brakes, tires, and fluid levels, as these are fundamental elements that directly impact vehicle performance and safety on the road.

Lights are crucial for visibility and communication with other drivers, ensuring that signals are displayed for turns and stops. Brakes are imperative for stopping the vehicle safely and preventing accidents, making their inspection a high priority. Tires must be checked for proper inflation and tread depth to ensure good traction and handling under various conditions. Additionally, fluid levels (such as oil, coolant, and brake fluid) should be monitored to avoid mechanical failures during a trip.

The other choices consider partial aspects of vehicle safety but do not encompass the full scope needed for thorough pre-trip inspections. For example, only checking oil and fuel levels excludes critical safety elements like brakes and tires. Similarly, focusing solely on external damage and interior cleanliness neglects mechanical components essential for safe operation. Limiting inspections to just brakes and lights disregards other significant factors like tire condition and fluid levels that can affect the vehicle's overall performance. Thus, the highlighted option provides a well-rounded approach to
