Controlled Substances and Alcohol Testing Management Information System (MIS) Statistical Data
Controlled substances and alcohol testing rates.
The FHWA is announcing the motor carrier industry's 1994, 1995, and 1996 controlled substances and alcohol testing positive rates. The controlled substances testing positive rate was 2.6 percent in calendar year 1994, 2.8 percent in 1995, and 2.2 percent in 1996. The alcohol testing ``violation'' rate was 0.14 percent in 1995, and 0.18 percent in 1996. Because the violation rate was below 0.5 percent for two consecutive years, the FHWA is announcing it is lowering the random alcohol testing rate for calendar year 1998 to 10 percent, in accordance with the provisions of the testing regulations.
