Engine idling impacts include effects on fuel efficiency and a company’s bottom line. Which option lists these impacts?

• A. Fuel Efficiency
• B. Your Company’s Bottom Line
• C. How Quickly a Vehicle Can Accelerate
• D. Both A and B

Answer: (D)

Engine idling wastes fuel because the engine runs without moving the vehicle, so fuel is used without productive work. That wasted fuel lowers fuel efficiency and increases operating costs, which directly hit a company’s bottom line. Because idling affects both how efficiently fuel is used and how much money is spent on fuel, the most complete answer is the one that lists both impacts. The option about acceleration isn’t a direct consequence of idling, since acceleration relates to throttle response and power rather than idle time. Saying only one of the two effects misses part of the impact, while including both captures the real cost and efficiency implications of idling.
