Which statement is NOT an exception to the rule against extended engine idling?

• A. Emergency equipment is in use.
• B. A suspect in the vehicle.
• C. A canine in the vehicle.
• D. The vehicle is being fueled.

Answer: (D)

Extended engine idling is allowed only in a few safety- or welfare-related scenarios. Those exceptions include situations where emergency equipment is in use, because you may need power for operations and cooling, and situations where a suspect or a canine is in the vehicle, to maintain safety, temperature, and ventilation for people or animals involved. The act of fueling, however, requires the engine to be off to prevent the risk of fire or ignition from flammable vapors. Because fueling does not permit idling, the statement about the vehicle being fueled is not an exception to the no-idling rule.
