Class A CDL Pre-Trip Inspection 2025 – 400 Free Practice Questions to Pass the Exam

During a pre-trip inspection, it is important that spare fuses are present and in good condition. This ensures that if any fuses in the vehicle are blown during operation, a driver can readily replace them to maintain the proper function of critical electrical systems. Having spare fuses available is not only a good practice but also adds to the overall safety and reliability of the vehicle.

While it might seem advantageous for spare fuses to be new and unused, the critical factor is that they are functional and can be relied upon when needed. Fuses that are broken or damaged would not serve their intended purpose, which can lead to operational issues. The color of the fuses matching the vehicle is irrelevant, as it's the functionality and presence that matter most. Therefore, ensuring that spare fuses are present and in good working condition is key to a thorough pre-trip inspection.
