Employers may legally require employees to undergo testing for illegal substances under certain conditions, which is why this choice is the most accurate. The legal framework surrounding drug testing often considers factors such as the type of job, the industry standards, safety regulations, and the company's drug-free workplace policies.

In many jurisdictions, employers can implement testing programs, especially for positions that involve safety-sensitive tasks, such as operating heavy machinery or transportation. For instance, the Department of Transportation requires drug testing for certain employees in safety-sensitive positions to ensure public safety and compliance with federal regulations.

Furthermore, employers often need to inform employees about the testing policies and obtain consent, ensuring that they comply with privacy laws and any applicable labor agreements.

While some options may suggest that testing is categorically allowed or forbidden, the reality is nuanced. Thus, understanding the specific legal and contextual factors involved is critical for recognizing when drug testing can be mandated legally.
