Abstract
The statistics show that 597,000 breath screening tests were administered in England and Wales in 1990; this represented a 10-percent increase over 1989 and a 49-percent increase over 1987. Ninety-three thousand tests were positive, a decrease of 5000 from 1989; these reductions occurred despite the large increase in testing. The positive proportion of breath tests fell to 16 percent in 1990 from 18 percent in 1989 and 25 percent in 1987. The number of tests after traffic accidents totaled 130,000 in 1990, of which 12 percent were positive. There were 89,000 positive evidential tests, a decline of nearly 6000 from 1989. During the 1990 Christmas campaign period against drunk driving, 73,000 screening breath tests were carried out, of which 5 percent were positive. 12 tables and 12 notes
