What should you inspect during the pre-trip inspection?

During the pre-trip inspection, it is essential to thoroughly check a comprehensive list of components to ensure the vehicle's safety and functionality. This includes not only tires, brakes, and lights but also fluid levels and other critical vehicle components such as mirrors, wipers, and horn.

Inspecting tires involves checking for proper inflation, tread depth, and any visible damage. Brake checks are vital for assessing the system's effectiveness, while lights ensure visibility and signaling compliance. Fluid levels must be monitored to avoid issues during operation, covering everything from oil to coolant. Other components, such as the battery, belts, and hoses, are also critical to the vehicle's overall performance.

The approach taken in choice C emphasizes a holistic view of the vehicle's condition, which is in line with the standards for preparing for safe driving. Thorough inspections help prevent breakdowns and accidents on the road, making it a crucial practice for commercial drivers.
