A recent report by the National Highway Traffic Safety Administration shows that the number of drunken driving arrests has been declining. Surveys show that in 2007, the number of drivers having a blood alcohol level of 0.08% or higher have declined to 2.2%. In 1973, the percentage of intoxicated drivers was 7.5%. Unfortunately, the number of drivers testing positive for drugs has increased. With 16% of drivers testing positive for drugs, law enforcement agencies are utilizing urine testing if drugs are suspected. In Hillsborough County, if a breath alcohol reading shows a result of .05% or lower, a urine test will be requested to test for the presence of drugs.
