What is the main purpose of the DOT drug testing program?

The primary purpose of the Department of Transportation (DOT) drug testing program is to ensure the safety of drivers and the public. This program is designed to prevent substance abuse among transportation employees, particularly those in safety-sensitive positions, which include roles such as commercial drivers, pilots, and rail workers.

By conducting regular drug testing, the DOT aims to reduce the risk of accidents and injuries that can result from impaired driving or operation of transportation vehicles. The underlying goal is to promote a safe working environment and protect the well-being of both employees and the general public.

The other choices, while they may relate to various aspects of workplace policies, do not capture the central aim of the DOT drug testing initiative. Maintaining employee confidentiality, compliance with labor laws, and providing treatment for those who test positive are important factors in the broader context of employee support and legal frameworks, but the core focus of the DOT program is on safety.
