What should you check during a pre-trip inspection?

Answer: B — Tires, lights, brakes, and mirrors

During a pre-trip inspection, it is crucial to check tires, lights, brakes, and mirrors because these components are essential for safe vehicle operation. Tires need to have the correct pressure and tread depth to ensure good grip and handling. Faulty brakes can compromise stopping power, which is critical for safety. Lights, including headlights, taillights, and turn signals, must be functional for visibility and effective communication with other road users. Mirrors are vital for checking blind spots and ensuring awareness of surrounding traffic. While checking engine fluid levels, interior cleanliness, and GPS functionality may also be important, they do not address the immediate safety factors that can impact driving. Thus, focusing on tires, lights, brakes, and mirrors helps ensure that the vehicle is roadworthy and reduces the risk of accidents.
