In this evaluation of the environmental components of the Swedish driver education class B, license holders that obtained a license since half a year have been asked how much education in environmental friendly driving they have received. Their answers have been used to define a group of 25 drivers with much such education (group M) and a group of 25 drivers with little or none such education (group L). These drivers have driven 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 behaviours. As a reference, an expert/educator in environmental friendly driving “E” has also driven the same road as the others with the purpose of indicating what is possible to achieve.
