What are non-standardized field sobriety tests?
Non-standardized sobriety tests have not been standardized by the National Highway Transportation Safety Administration (NHTSA). This means that police officers are not required to follow any specific guidelines or standards when giving these types of field sobriety tests. Like standardized sobriety tests, the objective of these non-standardized sobriety tests is to help the officer determine probable cause for arresting an individual for DUI / DWI. An inherent issue with non-standardized field sobriety testing is the fact that the administration of these tests may vary a great deal from one police officer to the next.
Because there are no “set standards” when giving non-standardized sobriety tests, they are typically called into question by experienced DUI / DWI lawyers during DUI prosecutions.
There are several non-standardized field sobriety tests that are commonly giving by police officers to individuals they believe may be driving while impaired.
