In the movie, The Man With Two Brains, Steve Martin’s character is subject to ridiculous roadside sobriety tests. Some of the tests to which Ohio drivers are subjected are also suspect. One such test is the Finger Dexterity test.
While not part of the three-test Standardized Field Sobriety Test battery, the Finger Dexterity test is prescribed by officer training as a tool to be used to determine if the officer is justified in continuing the detention of the driver. If reasonable articulable suspicion of impairment is shown, the officer is justified in asking the driver to exit the car to take standardized tests. The test is not scientifically validated to demonstrate impairment, but Ohio police officers use it anyway. The non-standardized tests are allowed into evidence despite their lack of correlation to impairment.
Below is an example of the Finger Dexterity test. Demonstrate the test to your friends and co-workers to see if you can spot signs of intoxication.
