Which driving habit improves fuel economy the most?
- A Rapid acceleration and hard braking
- Smooth, gradual acceleration and gentle braking
- C Frequent high-speed bursts
- D Idling for long periods to keep the engine warm
Why: Smooth acceleration and gentle, anticipated braking use far less fuel than aggressive starts and hard stops.
How do under-inflated tires affect fuel consumption?
- A They reduce fuel consumption
- B They have no effect
- C They only matter in summer
- They increase fuel consumption due to higher rolling resistance
Why: Low tire pressure increases rolling resistance, making the engine work harder and burn more fuel, so keep tires properly inflated.
What is the best way to reduce fuel wasted while stopped or waiting?
- A Rev the engine periodically
- B Leave it idling all day
- Avoid unnecessary idling by shutting the engine off when stopped for a while
- D Idle in a higher gear
Why: Unnecessary idling burns fuel and produces emissions for no benefit; turning the engine off during longer stops saves fuel.
Driving at a steady, moderate speed instead of a high speed mainly helps because:
- Aerodynamic drag and fuel use rise sharply at higher speeds
- B Higher speeds use no extra fuel
- C It is the only legal way to drive
- D It increases engine wear
Why: Air resistance climbs rapidly with speed, so a steady moderate speed uses noticeably less fuel than running fast.
"Progressive shifting" saves fuel by:
- A Holding each gear to high RPM before shifting
- Shifting up early, keeping engine RPM low while accelerating
- C Skipping the clutch entirely
- D Accelerating in neutral
Why: Progressive shifting means upshifting as early as practical to keep RPM low, which reduces fuel burn during acceleration.
How does anticipating traffic ahead help fuel economy?
- A It only helps in the city
- B It allows you to drive faster
- C It has no fuel benefit
- It lets you maintain a smoother, steadier speed with less braking
Why: Reading traffic far ahead lets you ease off early and keep a smooth speed, avoiding the fuel waste of repeated hard braking and acceleration.
