In Montgomery v. State, 174 Ga. App. 95 (329 SE2d 166) (1985) the Court concluded that a DUI suspect had not been compelled to perform field sobriety tests in violation of his right against self-incrimination, because "he was not threatened with criminal sanctions for his failure to perform the tests; he was neither physically forced to do the tests, nor was there a show of force tantamount to an actual use of force; and he did not refuse to perform the tests." Id. at 96 (1)
