Correct Answer:

Check the vehicle's lights

Explanation:

The first step in a pre-trip vehicle inspection is to check the vehicle's lights. This step is crucial because the lights are essential for visibility and safety while driving. Ensuring that all lights—headlights, brake lights, turn signals, and hazard lights—are functioning properly helps in preventing accidents and ensuring that other drivers can see you on the road, especially in low visibility conditions. Starting with the lights allows the driver to identify any immediate issues that could lead to safety hazards during a trip. Once you are satisfied that the lights are functioning, you can then proceed to check other critical components, such as the oil level, tires, and brakes, which are also vital for the safe operation of the vehicle.
