Texas CDL General Knowledge Practice Exam

During a pre-trip inspection, which of the following items is NOT checked?

1. A. Tire pressure

2. B. Brakes

3. C. Amount of fuel in the vehicle

4. D. Lights and reflectors

The correct answer is: C. Amount of fuel in the vehicle

During a pre-trip inspection, checking the amount of fuel in the vehicle is not a typical focus because the primary concerns are ensuring that safety-related and operational components of the vehicle are functioning properly. The pre-trip inspection is primarily aimed at identifying any mechanical issues that could lead to accidents or vehicle breakdowns while on the road. Tire pressure is crucial for maintaining proper handling and safety, as under-inflated or over-inflated tires can affect stability and braking. Brakes are one of the most critical safety features, and their condition must be assessed to ensure the vehicle can stop effectively. Lights and reflectors are equally important as they enhance visibility for both the driver and other road users, particularly in low-light conditions. While having an adequate amount of fuel is necessary for operational readiness, it is not typically categorized as a safety or mechanical concern during the inspection but rather as a matter of operational efficiency. Thus, the correct answer highlights that fuel levels are monitored more for planning, rather than being a critical point of inspection.
