The study shows that a driving licence tuition system should be produced which would ensure that all those who obtain a driving licence have practised all items included as test items in the driving test. This can (apart from the awaited changes in the introductory tuition, new curriculum B and enhanced skid training) mean changing the existing driving test. One reason for this is that analyses of tuition patterns and driving test results show that those who have a larger proportion of their tuition covering certain items (for example, hard braking during private tuition and overtaking on 70 km/h roads and 90 km/h roads during driving school lessons) have a greater chance of not passing instead of passing the driving test. Another reason is that several of the items which the greatest proportion of those who have recently passed the test have never practised, either privately or with a driving school, also belong to the items that are included only to a small extent in the driving test. Examples of this are the items efficient braking, overtaking and driving in a roadwork's area. This should indicate that learner drivers and/or lay instructors, and also driving instructors/driving schools, in some way are aware of this fact, for which reason they conduct less tuition covering these items. The study was carried out with three aims; to describe how people aged 18-24 who have recently got their driving licence (category B driving licence) went through their driving instruction; to investigate, whether it can be explained why certain 18-24-year-olds passed the category B driving licence test, or did not pass it, respectively; and to describe what deficiencies of competence there are with 18-24-yearolds who did not pass the category B driving licence test.
