  1. What is eco-driving and why is it important for professional HGV drivers?

    Answer: A driving style that reduces fuel consumption, emissions, and vehicle wear through smoother, more efficient driving

    Eco-driving involves techniques such as smooth acceleration, anticipating traffic flow, maintaining steady speeds, and correct gear use. It can reduce fuel consumption by 10-15%, lower emissions, reduce brake and tyre wear, and improve road safety.

  2. How does tyre pressure affect fuel consumption?

    Answer: Under-inflated tyres increase rolling resistance, increasing fuel consumption by up to 3%

    Under-inflated tyres increase rolling resistance, meaning the engine has to work harder to move the vehicle. This can increase fuel consumption by up to 3% and also causes uneven tyre wear, reducing tyre life and potentially compromising safety.

  3. What is the purpose of the UK Clean Air Zones (CAZs)?

    Answer: To reduce air pollution by charging vehicles that do not meet emission standards to enter designated areas

    Clean Air Zones charge vehicles that do not meet minimum emission standards (typically Euro 6 for diesel HGVs) to enter designated urban areas. Cities including Birmingham, Bristol, and Bath have implemented CAZs to improve air quality.

  4. What is AdBlue and why is it used in modern HGVs?

    Answer: A urea-based solution injected into the exhaust to reduce nitrogen oxide (NOx) emissions

    AdBlue is a urea-based solution used in Selective Catalytic Reduction (SCR) systems. It is injected into the exhaust to convert harmful nitrogen oxides (NOx) into harmless nitrogen and water, helping vehicles meet Euro 6 emission standards.

  5. How does excessive engine idling affect the environment?

    Answer: It produces unnecessary emissions, wastes fuel, and contributes to local air pollution

    Excessive engine idling produces unnecessary CO2, NOx, and particulate emissions while wasting fuel. Many local authorities have anti-idling bylaws, and unnecessary idling near schools, hospitals, or residential areas is particularly problematic.

  6. What is the 'green band' on an HGV rev counter?

    Answer: The most fuel-efficient rev range for normal driving

    The green band on the rev counter indicates the most fuel-efficient operating range for the engine. Driving within this range (typically 1,000-1,500 rpm for modern HGVs) optimises fuel consumption and reduces emissions while maintaining adequate performance.
