Why might an officer choose to consult with a supervisor after administering the HGN test?

An officer may choose to consult with a supervisor after administering the HGN test primarily for accountability and ensuring that the test was conducted properly. This step is crucial because the HGN test is a standardized field sobriety test used to assess potential impairment due to alcohol or drugs. Consulting with a supervisor helps to ensure that the results are interpreted correctly, any procedural nuances have been adhered to, and any potential issues that arise during the testing can be addressed appropriately. This oversight can provide additional layers of verification for the test results and bolster the integrity of the overall process, ultimately leads to more reliable assessments in the context of a DUI investigation.
