The aim of the study was to measure the effects of the education in environmental friendly driving that is included in the Swedish driver education for license class B on fuel consumption and a selection of driving behaviour that are typical for environmental friendly driving among drivers with license since half a year. Comparisons were made between a group of 25 drivers who estimated that they had much  education in environmental friendly driving and a group of 25 drivers who estimated that they had  little or none such education. Those with much education in environmental friendly driving had participated more in both driving lessons and theory lessons at driving schools than those with little education. The drivers drove an instrumented car along a pre-defined road of 30 km where 12 parts were used to collect data about fuel consumption and a selection of different driving behaviour.  The results show that education in environmental friendly driving during driver licensing has had an effect on fuel consumption. The group with much education used 8.7 percent less fuel than the group with little education. However, an expert/educator in environmental friendly driving who was driving the same roads had a much lower fuel consumption. This can probably be explained by the more complex driving behaviour, such as driving in mixed traffic with zero consumption and to minimize declutching and braking to the advantage of engine braking, requiring a higher mental load of novice drivers.
