The study is aimed at understanding if (a) declared driving behavioural changes due to familiarity can be observed through surveys; (b) self-reported route familiarity can be related to negative safety performances (crashes and fines); (c) the relationships are stable across different countries. Driving on habitual routes could imply different behaviours than on generic routes, and possibly different safety performances. The relationships between route familiarity and safety performances are often searched through experimental studies or accident data analyses. Surveys were spread to young Italian and Norwegian drivers, asking both general and specific questions on the habitual route travelled and the recently experienced crashes and fines. 316 answers, 235 Italian and 71 Norwegian, were analysed. Comparisons of self-reported driving scores between generic and habitual routes were performed. Logistic regressions having as response variables negative outcomes (crashes and fines) on frequent routes, different behaviour on habitual routes, and nationality were developed. Different relationships were highlighted, concerning differences in perceived ability on the habitual route, a possible excess of self-confidence, which however are differently related to crashes and fines. Different tendencies were found for the same variables in the two countries, sometimes opposite. Surveys are suggested as useful to reveal familiarity-behavioural changes/negative outcomes relationships. Considering international studies may reveal significant driving behavioural differences and patterns. The results have some potential applications for driver education, since some relationships between familiarity effects in young drivers and negative safety outcomes were noted.
