While much of the training is classroom-based, the deputies were able to test subjects hands-on Wednesday to give themselves a benchmark of how an impaired driver would react to field sobriety tests. Master Deputy Jon Osborne.
Year-to-date in 2012, York County Sheriff’s Deputies have made 188 DUI arrests — a stark increase over the 137 total DUI arrests in 2011.
Osborne says the tests give officers a benchmark as to how to accurately give suspected drunk drivers field sobriety tests.
And while sobriety tests seen on TV — like walking in a straight line — are part of the test, one of the more accurate sobriety tests involves measuring eye movement.
Osborne says there are a number of tests — called cues — that when added together, help determine if a suspect is driving above the legal limit. Osborne says giving every suspected drunk driver a breathalyzer test is, among other things, just not practical.
The three test subjects in Wednesday’s training were kept under close supervision all day and were driven to and from the county’s training center.
