Abstract
Between the mid-1980s and the early 1990s, DUI in the Netherlands decreased strongly: in weekend nights, the proportion of drivers with an illegal BAC (> 0.5 g/L) dropped from 12% in 1983 to 3.9% in 1991. This favourable development followed the introduction and extension of random breath testing, facilitated by the introduction of electronic screening devices and evidential breath testing. In recent years, however, DUI has not decreased any further, and even tended to increase. This may have been caused by an indecisive government policy towards drink-driving.
