Which of the following is true concerning medical examinations for CMV drivers?

The statement that falsifying results can lead to serious consequences is accurate due to the critical nature of medical examinations for commercial motor vehicle (CMV) drivers. These examinations are not just routine; they ensure that drivers meet specific health and safety standards necessary to operate large vehicles on public roads.

When a driver provides false information or fabricates results regarding their health status, they compromise their own safety, the safety of others on the road, and potentially violate legal regulations governing commercial driving. The consequences can include severe penalties such as the suspension of driving privileges, legal action, and increased liability in the event of an accident. Hence, maintaining integrity in medical examinations is essential to uphold safety standards and legal compliance in the industry.

The other options are inaccurate in the context of CMV driver medical examinations. Medical exams are mandatory rather than optional (which contradicts the first choice), and they assess not only physical health but also other health-related aspects that could affect driving ability. Lastly, while personal health information is generally protected, results may still be shared under certain circumstances in accordance with regulations and organizational policies.
