Which of the following is NOT a result of failing an HGN test?

The conclusion drawn regarding the comprehensive drug assessment being the option that does not result from failing an HGN test aligns with the understanding of DUI procedures and their associated processes. When an individual participates in an HGN test, it is primarily a field sobriety test designed to detect impairment from alcohol or certain drugs.

Failing the HGN test typically leads to several immediate consequences, including the possibility of arrest based on the officer's evaluation of impairment. Additionally, legal implications related to DUI charges often arise, as the HGN test results can be used as evidence in court. Furthermore, if the individual is arrested for DUI, they may face an immediate suspension of their driver's license depending on the state's regulations.

In contrast, a comprehensive drug assessment is not a direct result of failing the HGN test itself. Such assessments are often utilized as a means of evaluating an individual's substance use and may be required through court sentences, rehabilitation programs, or other interventions, rather than being an automatic consequence of failing the HGN. Thus, this demarcation makes the option about the comprehensive drug assessment the correct choice, as it does not directly correlate with failing the test.
