What is an inferred recommendation if a subject displays multiple indicators of impairment?

When a subject displays multiple indicators of impairment, the most logical step is to assess further with breath or blood alcohol testing. This recommendation is based on the need for a more definitive measure of impairment, as field sobriety tests can provide observable signs of intoxication but are inherently subjective and can be influenced by various factors, such as the environment or the individual's physical abilities.

Breath or blood alcohol testing offers quantifiable data regarding a person's blood alcohol concentration (BAC), which is a more objective measure of impairment. This helps law enforcement officers make informed decisions regarding arrest and further legal action.

Using other methods like conducting a field sobriety test or making a visual assessment might provide initial observations, but they do not provide the concrete evidence needed in a situation where impairment is suspected. Offering a ride home does not address the potential legal implications or safety concerns related to a subject's impairment. Therefore, the inference to conduct breath or blood alcohol testing is appropriate in this scenario.
