Spare electric fuses must be on the bus unless the vehicle is equipped with what?

• A. Circuit breakers
• B. AI system
• C. GPS
• D. ABS

Answer: (A)

Spare electric fuses must be on the bus because fuses serve as the protection for electrical circuits. The rule changes if the vehicle is equipped with circuit breakers, which take over that protective role. A circuit breaker trips when there’s an overload or fault, cutting the current to protect the circuit. After the fault is addressed, you can reset the breaker to restore power, so you don’t need to carry spare fuses. If the system relies on fuses rather than breakers, you’d still need to have spare fuses on hand to replace any blown ones. The other options (AI system, GPS, ABS) aren’t related to fuse protection or replacement requirements.
