Who has the authority to order a test based on reasonable suspicion?

Answer: C — Your trained supervisor

The authority to order a test based on reasonable suspicion rests with a trained supervisor. This is because trained supervisors have received specific instruction on what constitutes reasonable suspicion related to substance abuse. They are equipped to observe behavior or signs that may indicate a violation of the company's drug and alcohol policies. This ensures that the decision to request a test is made based on established criteria and a professional assessment, rather than impulse or misunderstanding. Meanwhile, other choices like any driver, a co-worker, or the company owner lack the specific training required to recognize the signs of impairment or substance abuse effectively. While a co-worker or the company owner may have concerns, they do not have the formal training to assess situations in the same way. Therefore, only a trained supervisor is authorized to take the necessary steps to ensure compliance with safety regulations and the integrity of the testing process.
