A CDL holder must submit to drug and alcohol testing in specific circumstances that align with federal regulations aimed at ensuring safety on the road. The correct answer indicates that testing is required when a driver is randomly selected for testing or if they are involved in an accident.

Random selection is a crucial component of the testing process, as it helps maintain a consistent and unbiased method for ensuring drivers are not under the influence of drugs or alcohol while operating commercial vehicles. This randomness is intended to deter substance abuse among drivers, thereby enhancing public safety.

Additionally, drug and alcohol testing must be conducted following an accident, particularly if there is a fatality, injury, or significant property damage involved. This is important because it establishes accountability and safety standards in the commercial driving industry, allowing for thorough investigations of incidents that could be influenced by substance use.

In contrast, testing upon request by fellow drivers or only during initial employment does not address the broader regulatory framework established for ongoing safety monitoring or responsiveness to incidents, which is critical in the field of commercial driving.
