It's possible to be charged with a DUI in Florida without taking a single sip of alcohol. Tiger Woods proved that this week when he blew a .000 and still ended up behind bars.
Jupiter, Fla., police on Wednesday released a dashcam video showing Woods taking sobriety tests. Woods told officers he had not been drinking, but had taken medication.
In the temperate eyes of state law, driving on drugs _ be they prescription or otherwise _ is equivalent to driving drunk.
"You just have to remember when you have taken these prescriptions, if you're impaired you're impaired, whether it's alcohol or drugs," said Sgt. Mark Wysocky, Florida Highway Patrol spokesperson.
It is difficult however to measure impairment and harder to get a conviction, especially in the case of prescription drugs.
A good roadside test doesn't exist for drug testing, according to the National Institute on Drug Abuse.
Unlike a breathalyzer, drug testing doesn't prove a driver was impaired behind the wheel.
In Florida, there are no legally defined levels of drugs that say a person was impaired.
