Combinations of field sobriety tests and chemical tests for alcohol and drugs are used to make arrests and secure convictions for operating a vehicle while impaired (OVI).

The officer administering the tests determines whether a suspect has passed, making the outcome subjective. The tests themselves pose difficulties completely unrelated to the use of intoxicants. Uncontrolled eye movements often afflict people with a lazy eye or a past brain injury. Poor hearing, inner-ear conditions, bad balance, and bad footwear can produce a poor performance on the walk and turn. Elderly and overweight individuals may simply lack the muscle strength and coordination to complete these physical tasks.
Regarding the chemical tests, refusing to provide a breath, blood, urine sample will result in an immediate license suspension. Failing a chemical test also results in an immediate license suspension and will later be introduced as evidence in your case.
The results of the chemical test can be unreliable for several reasons. Poor collection methods, lack of refrigeration, improper sample labeling, improper machine maintenance, and improper calibration can all lead to inadmissible results. The custody of each sample must be fully documented and unbroken. A knowledgeable Ohio sobriety test attorney will know how to check on and challenge each of these procedural details.
Police rely heavily on their interpretations of field sobriety tests to make an arrest and then perform lab tests for alcohol and drugs. Prosecutors and judges put great faith in the lab results.
