How can drivers improve fuel efficiency?

• A. By decreasing tire pressure
• B. By maintaining steady speeds and reducing idling time
• C. By accelerating rapidly
• D. By driving at high speeds

Answer: (B)

Maintaining steady speeds and reducing idling time is a highly effective way for drivers to improve fuel efficiency. When a vehicle accelerates or decelerates frequently, it consumes more fuel due to the extra energy required to overcome inertia. By driving at a consistent speed, especially on highways, drivers can optimize their fuel consumption.

Additionally, minimizing idling time is crucial. When a vehicle is idling, it continues to use fuel without any movement, which leads to waste. By turning off the engine during long stops or when waiting, drivers can conserve fuel. These practices not only enhance fuel efficiency but also contribute to a reduction in emissions, supporting better environmental outcomes and saving money on fuel costs.

In contrast, options involving decreasing tire pressure and high-speed driving typically result in reduced fuel economy, while rapid acceleration also leads to increased fuel consumption.
