What should an officer document if a breath test cannot be administered?

When a breath test cannot be administered, it is essential for an officer to document the reason for not conducting the test. This is crucial because it provides a clear record of the circumstances surrounding the incident, which can be critical in legal proceedings. Documenting the reason offers justification for the actions taken and can also help establish the credibility of the officer's decisions during the traffic stop.

For instance, if the breath test was not performed due to a malfunctioning device or if the driver was unable to take the test due to medical issues, having a documented reason ensures that there is clarity about why the standard procedure was not followed. This record can protect the officer and the agency by ensuring that all actions taken are well-supported and justified if challenged in court.

The other options, while they may also be important to document, do not provide the same level of necessary information regarding the specific situation that prevented the breath test from occurring.
