HC Deb 04 August 1980 vol 990 c74W
Dr. Roger Thomas

asked the Minister of Transport which countries of which he is aware with traffic problems and densities similar to those in the United Kingdom have introduced random testing of motorists for alcohol levels in body fluids; and whether in those countries such procedures have reduced the incidence of road traffic accidents and consequent mortality and morbidity.

Mr. Fowler

I understand that random testing is permitted in Belgium, Canada, Denmark, Finland, France, the Federal Republic of Germany, the Netherlands, Norway, Sweden and Yugoslavia. The evidence I have about the effect on accidents and casualties is inconclusive.
