Difficulty: EasyEnvironmental Impact and Fuel Efficiency

Which driving habit helps to lower fuel consumption and reduce harmful exhaust emissions?

  1. A
    Coasting downhill in neutral to keep the engine at idle speed
  2. Anticipating road conditions early and easing off the accelerator smoothlyAnswer
  3. C
    Keeping tyre pressures slightly below recommended levels for better comfort
  4. D
    Accelerating briskly through lower gears to reach cruising speed immediately

Answer

Anticipating road conditions early and easing off the accelerator smoothly
Anticipating road conditions well ahead allows drivers to decelerate smoothly and avoid harsh braking. This gentle driving technique maintains steady vehicle momentum, significantly lowers fuel consumption, and cuts down toxic exhaust emissions.

Step-by-Step Solution

1
Identify the primary driving habits that cause excessive fuel consumption
Frequent sharp acceleration and harsh braking cause unnecessary energy loss and produce higher exhaust emissions.
Smooth driving maintains vehicle momentum and avoids wasting energy.
2
Evaluate how early hazard anticipation affects vehicle efficiency
Scanning ahead allows the driver to ease off the accelerator early, utilizing engine braking and fuel overrun cut-off mechanisms.
Eco-safe driving relies on planning ahead to minimise complete stops and abrupt speed changes.
