During a recent OVI jury trial, the judge and I disagreed about the function of standardized field sobriety tests (SFSTs). During a sidebar, I argued the tests do not measure driving impairment; they predict blood alcohol concentration (BAC). The judge’s opinion was SFSTs measure impairment of driving ability. The judge’s opinion prevailed, despite being wrong, because the judge’s opinion always prevails in the judge’s courtroom (unless and until an appellate court says otherwise). This particular judge is intelligent, well-intentioned, and better educated on DUI/OVI issues than most judges and lawyers. If this judge misunderstands the purpose of SFSTs, it’s a topic worth addressing.

Fourth amendment law does not lend itself to mathematical formulas. Rather than using equations to decide Constitutional issues, courts look at the totality of the circumstances and make decisions on a case-by-case basis. This is particularly true when it comes to the issue of whether an officer had probable cause to justify an arrest. However, one theorem illustrated by a recent Ohio OVI case is this: clues on Field Sobriety Tests (FSTs) does not equal Probable Cause (PC).
