DVSA Environmental Awareness 2 — Questions and Answers
Question 1: How can removing unnecessary items from your vehicle improve fuel efficiency?
- It can't — the difference is negligible
- Extra weight increases fuel consumption, so removing unnecessary heavy items reduces fuel use (Correct answer)
- Only removing roof items makes a difference
- Weight only matters for electric vehicles
Correct answer: Extra weight increases fuel consumption, so removing unnecessary heavy items reduces fuel use
Every extra kilogram your vehicle carries requires more fuel to move. Removing unnecessary heavy items from the boot or cabin reduces weight and improves fuel economy.
Question 2: What is the environmental benefit of using a roof box only when needed?
- Roof boxes have no environmental impact
- Removing it when not in use reduces aerodynamic drag and can save up to 20% on fuel at motorway speeds (Correct answer)
- It only saves about 1% fuel
- It only matters on electric vehicles
Correct answer: Removing it when not in use reduces aerodynamic drag and can save up to 20% on fuel at motorway speeds
An empty roof box significantly increases aerodynamic drag, especially at higher speeds. Removing it when not in use can reduce fuel consumption by up to 20% at motorway speeds.
Question 3: What does Euro 6 refer to in relation to vehicle emissions?
- The price of fuel in Europe
- The current European emission standard that limits the amount of pollutants a vehicle can produce (Correct answer)
- A type of fuel
- A European road classification
Correct answer: The current European emission standard that limits the amount of pollutants a vehicle can produce
Euro 6 is the current European emission standard that sets maximum limits for pollutants including nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM) from vehicle exhausts.
Question 4: How does eco-driving benefit you financially as well as environmentally?
- It doesn't — it only helps the environment
- Smoother driving reduces fuel consumption, tyre wear, and brake wear, saving money (Correct answer)
- It only saves money on electric vehicles
- The savings are too small to notice
Correct answer: Smoother driving reduces fuel consumption, tyre wear, and brake wear, saving money
Eco-driving techniques reduce fuel consumption by 10-15%, extend tyre and brake life, and reduce maintenance costs. This translates to significant financial savings over time.
Question 5: What is the congestion charge in London?
- A charge for using the motorway
- A daily charge for driving in the central London zone during specified hours to reduce traffic and pollution (Correct answer)
- A parking fee in London
- A toll for crossing the Thames
Correct answer: A daily charge for driving in the central London zone during specified hours to reduce traffic and pollution
The congestion charge is a daily fee for driving within central London during charging hours (typically 7am-6pm, Mon-Fri and some weekends). It aims to reduce congestion and improve air quality.
Question 6: Which type of alternative fuel vehicle produces zero tailpipe emissions?
- Diesel hybrid
- Fully electric (battery electric) vehicle (Correct answer)
- Petrol hybrid
- LPG vehicle
Correct answer: Fully electric (battery electric) vehicle
Fully electric (battery electric) vehicles produce zero tailpipe emissions as they are powered entirely by electric motors and batteries with no internal combustion engine.
