Drivers can reduce their vehicle's environmental impact through sensible driving habits and routine checks. Match each vehicle condition or driving habit to its direct consequence on fuel efficiency and emissions.
- Carrying unnecessary heavy clutter in the bootIncreases vehicle mass, requiring more energy to accelerate
- Driving with under-inflated tyresIncreases rolling resistance against the road surface, burning extra fuel
- Leaving the engine running while parked for a long periodCauses unnecessary exhaust emissions and wastes fuel while stationary
- Driving at speed in an unnecessarily low gearForces the engine to work at unnecessarily high RPM, consuming excess fuel
Answer
Carrying heavy clutter matches increasing vehicle mass; under-inflated tyres matches increasing rolling resistance; idling when parked matches producing emissions while stationary; driving in a low gear matches running the engine at high RPM.
Each habit or condition directly corresponds to a specific physical cause of inefficiency: extra weight requires more engine work to move; under-inflation raises rolling resistance; engine idling burns fuel at zero miles per gallon; and low gear selection keeps engine revs wastefully high.
