They're trained to spot drunk drivers and now DRUGGED drivers too

RACINE CO. (WITI) -- For officers patrolling the roads, there are some obvious "tells" when it comes to spotting drunk drivers. But what if the driver is high on something else?

In 2013, Racine County deputies made nearly 800 OWI arrests -- and the majority of those drivers were drinking. Most of them exhibited blood-shot eyes, slurred speech, alcohol on their breath -- all obvious signs. But when it comes to heroin and other opiates, those "tells" aren't so obvious.

For the first time in the county, five officers from several law enforcement departments went through an intensive four-week program to be certified "drug recognition experts."

"Someone who is using heroin, marijuana, alcohol, these other types of drugs also exhibit different signs and symptoms that associate with being impaired," said Racine County Sheriff Chris Schmaling.

The officers will use a more intensive field test to recognize the unique symptoms for a variety of illegal drugs -- and be able to make an arrest, even if a driver passes a breathalyzer test.

The newly-trained officers are part of the Caledonia, Sturtevant and Mount Pleasant Police Departments. They will not only help identify when someone is high behind the wheel, they'll also follow through and testify in court as an expert witness.
