Although, in theory, the HGN should be a helpful indicator of intoxication, it raises many concerns in practice. As Phoenix DUI lawyers, we’d like you to know about the problems with the HGN test during a DUI stop, including:
What's the Problem with the HGN in Arizona DUIs?
- Non-medical training of officers. Generally, police officers in Arizona complete a weekend-long training course that covers field sobriety tests, including the HGN. The trainers are usually also officers, and they are generally not medically trained to administer and interpret the results.
- Improperly administered testing. For the HGN test to give the most accurate results, your head must stay still, the object used must be a certain distance from you, etc. In actual practice in the field, these tests are often administered improperly, especially if the potential offender has been observed to be unsteady on his or her feet.
- Other conditions may cause similar results. Intoxication is not the only condition that can give a positive result for the HGN. Neurological disorders, ear infections, epilepsy, and even high blood pressure are among the numerous conditions that could cause a false positive on a DUI eye test in Arizona.
