Which action contributes to Eco-Driving?
Explanation: One of the many advantages of an eco-driving style, includes; increased fuel efficiency, reduced emissions and improved driver safety. The eco-conscious driver becomes a more efficient driver because they learn to read the road further ahead and display better anticipation skills. This reduces the need for harsh acceleration and braking which results in a more economical style of driving and a smoother journey.
