In the context of drug testing, "reasonable suspicion" refers to the observation of specific, observable signs or behaviors that indicate an employee may be under the influence of drugs or alcohol. This standard is used to justify conducting a drug test without prior notice or prior random selection.

Indicators of reasonable suspicion may include erratic behavior, slurred speech, difficulty with coordination, or other physical signs that suggest impairment. The essence of reasonable suspicion lies in the objective assessment of the employee's behavior rather than subjective feelings or assumptions about the individual.

Recognizing this, it is crucial for employers to document and corroborate observable behaviors that lead to the decision to administer a drug test, ensuring that the process remains fair and justifiable.
