In 2001, a survey was carried out by the Netherlands Transport Research Centre (AVV) to assess the alcohol consumption of car drivers. All 25 police regions participated in this study. The measurements were performed in 71 study districts during random sobriety checks that took place from March 2001 through January 2002. The measurements related to a random sample of drivers participating in traffic in the night from Friday to Saturday and from Saturday to Sunday, both between 10 p.m. and 4 a.m. All the drivers stopped were administered a breath test. The 2001 sample contained more than 25,000 drivers. The AVV study is a follow-up to previous studies into drink-driving. Until recently, these studies had always been carried out by SWOV. Contrary to 2000, police supervision was expanded in 2001. The most important conclusion made in the 2001 study was the significant reduction in the number of drink-driving offenders compared to 2000. In 2001, the figures for drink-driving fell to 4.2%.
