PBT results are primarily used to assist officers in determining what?

The use of Preliminary Breath Test (PBT) results is crucial in helping officers make an informed decision about whether an arrest should be made. When an officer suspects a driver is under the influence, the PBT serves as a tool to measure the blood alcohol concentration (BAC) level. If the PBT indicates a BAC above the legal limit, it provides the officer with evidence to proceed with an arrest for DUI.

This determination is based on the immediate need for evidence to support an arrest, rather than assessing potential charges or defenses. Additionally, while the PBT results can influence the investigation, they are not typically used for verifying driver’s licensing status. Thus, the primary purpose of the PBT is to assist in making the decision about an arrest, ensuring that law enforcement can act accordingly to maintain public safety.
