When facing an OVI (Operating a Vehicle while Impaired) charge in Ohio, defendants may find themselves subjected to various physical and mental tests administered by law enforcement officers. While certain tests like the Horizontal Gaze Nystagmus (HGN), Walk and Turn, and One Leg Stand are recognized as "standardized" by the National Highway Traffic Safety Administration (NHTSA) and have undergone validation studies, officers frequently employ other tests that lack this crucial standardization. One such test that has become increasingly common is the Modified Romberg Balance (MRB) test.
