What are the potential implications for a driver who fails the HGN test?

When a driver fails the Horizontal Gaze Nystagmus (HGN) test, the most significant implication is that they could be arrested and charged with DUI (Driving Under Influence). The HGN test is a standardized field sobriety test used by law enforcement to assess a driver's level of impairment due to alcohol or drugs. If the officer observes specific indicators of impairment during the test, it strengthens the case for legal action against the driver.

Upon failing the HGN test, the officer may gather further evidence, which could lead to an arrest and the initiation of DUI charges. Legal consequences for a DUI can include fines, license suspension, mandatory alcohol education programs, and even jail time, depending on the severity of the offense and whether it is a repeat offense. The test's results provide important evidence in court, so it plays a critical role in the legal process surrounding impaired driving incidents.
