Eyewitness News has learned that four out of 10 drivers stopped for DUI in Florida refuse breathalyzers. That is in spite of what is printed on Florida’s drivers licenses, “Operator of a motor vehicle constitutes consent to any sobriety test required by law.” Traditionally, the Fourth of July weekend is among the deadliest on Florida’s roads. If this year is like most, dozens of people will be killed by drivers who have been drinking. “It is a very dangerous weekend to be on the road,” said Assistant State Attorney Michelle Perlman. It is also very frustrating for law enforcement. The word is out in Florida that if you’re suspected of driving drunk you should not submit to a breath test. “I think in county court, DUI is probably 40 percent of the docket,” said Perlman. However, at least four out of 10 in Florida refuse a breath test, making prosecution more difficult.
