What Are the DUI Tests and is a Warrant Required in Oceanside?

Field Sobriety Tests: No Warrant

Police officers test for impairment in driving under the influence cases with a number of different tests. These include physical field sobriety tests - testing for horizontal gaze nystagmus, walk a straight line, heel to toe, stand on one leg, touch your nose, finger count, counting backwards, alphabet, 30-second time estimate, and hand pat. Field sobriety tests often involve several of these observational tests. The "suspect" is judged on appearance, following instructions and test performance.

Is the DUI Field Breath Test admissible in Vista Courts?

Generally the DUI field breath test or P.A.S. (Preliminary Alcohol Screening) test is admissible in Vista and throughout California absent any foundational errors in the procedures and calibration. The PAS test is administered usually in the field at the "stop" by a police officer. The DUI field breath test is not as reliable as other types of alcohol tests, and the jury may be so instructed if the case goes to trial.
