Abstract
The statistics show that 562,000 screening breath tests were reported in England and Wales during 1991, a decrease of 34,000 from 1990, but an increase of 22,000 over 1989 figures. There were 83,000 positive screening tests, representing 15 percent of the total; since 1988, the number of positive results has decreased by 18,000 even though the number of tests performed has increased significantly. Of the 83,000 figure, 78,000 were positive evidential tests, a decrease of 11,000 from 1990. The number of tests performed after vehicular accidents decreased by 15,000 in 1991, of which 12 percent were positive. Sixty-one thousand screening tests were conducted during the 1991 Christmas season, of which 3,300 were positive. 4 figures, 12 tables, and 13 notes
