Aim Research suggests an association between population drinking and a large number of outcomes. However, driving while under the influence of alcohol (DWI) is conspicuously absent from this list of outcomes. The aim of this study was to estimate the relation between DWI and total consumption of alcohol on annual timeseries data for Norway and Sweden. Design, setting, and measurements For Norway, we used data on convictions for DWI per 100000 inhabitants (aged 1569 years). The DWI proxy for Sweden comprised the proportion (%) of all police-reported traffic accidents with personal injuries where the driver was under the influence of alcohol. Data on total alcohol sales in litres of pure alcohol per inhabitant (aged 15 years and older) were used as proxy for total alcohol consumption. We focused on the period 195789, during which the legislation concerning DWI remained unchanged in Norway as well as in Sweden. The statistical analyses were based on co-integrated models. Findings The estimates of the association between DWI and per capita alcohol consumption were strongly significant in Norway as well as in Sweden. For Norway, the estimated elasticity equalled 2 (P<0.001) and for Sweden 1.5 (P<0.001). Conclusions In Norway and Sweden, as total population level of alcohol consumption increases or decreases so does the incidence of driving while intoxicated.
