Environmental awareness and an increased focus on health have put cycling on the agenda as a healthy and sustainable transport mode. While there are undoubtedly a lot of positive benefits stemming from a shift from car use to bike use, an increase in the number of bicyclists on the road might also have some negative impacts. More cyclists might reduce the number of cars on the road and give health benefits to the cyclists, but an increase in bike use might also lead to more cycling related accidents and an increase in unsafe cycling habits. One such cycling habit is cycling under the influence of alcohol (CUI). For many, the bike can serve as a practical and cheap alternative of getting home from bars, clubs or friends after one or many drinks. Little is known about alcohol consumption in combination with cycling in Norway. This study tried to understand some of the mechanisms behind CUI in Norway; the goal was to find out how prevalent CUI is in Norway, what the attitudes towards CUI in Norway are and what reasons there are for a person to ride a bike under the influence of alcohol. Data was collected in three complementing ways: First, informal focus group interviews in naturally occurring groups at pubs, bars and similar gave insights from stories and discussions among friends. Second, an online questionnaire gave more detailed information from a bigger part of the population and a broader category of questions. Third, focused interviews at nighttime on weekends and popular days to go out with persons about to park or leave on a bike, enabled the possibility of gaining information from cyclists influenced by alcohol to understand the considerations done when CUI actually happened. CUI can be seen as prevalent in Norway. Of 650 respondents in an online questionnaire, 82,6% (537 respondents) had done it some time during their life. Of these 537, 59,9%(322 respondents) had done it sometime the past year. These are more often male, young adults (20-39 years) and living in big Norwegian cities (>50 000 inhabitants). Attitudes are generally permissive towards a low level of alcohol influence, they become increasingly negative towards cycling under higher levels of influence. Permissive attitudes, having friends who also CUI and having family/friends who accept that a person does it, increase the possibility of doing it. Both higher cycling and drinking frequencies were associated with more CUI the last year. Typical reasons to ride a bike under the influence include nice weather, distances suitable for cycling and that riding a bike is enjoyable. The study uncovered a low knowledge of rules and regulations among the population. The law is quite vague, and possible problems related to enforcement of it was discovered. As CUI isprevalent in Norway, more data is needed on CUI related accidents, especially concerning riding a bike under a low level of influence.
