What should be done if a school bus driver's blood alcohol concentration is measured at any level?

If a school bus driver's blood alcohol concentration is measured at any level, it is essential to report to a supervisor immediately. This action is vital because even the presence of alcohol, regardless of the measured quantity, raises serious safety concerns regarding the driver's ability to operate the bus safely.

Reporting immediately ensures that appropriate measures can be taken to safeguard the safety of the passengers, the driver, and the public. It allows for timely intervention, which is critical since school buses transport children and other vulnerable populations. The situation demands prompt action to prevent any potential accidents or incidents that may arise from impaired driving.

The other actions would not address the serious implications of any alcohol level detected in a driver's system. Continuing to drive, even with caution, does not mitigate the risk involved. Driving with a passenger or seeking a medical check without first informing supervisors could lead to dangerous situations, undermining the safety protocols designed to protect everyone involved in school transport.
