What should an officer do if the driver shows signs of intoxication upon initial contact?

When an officer encounters a driver who displays signs of intoxication, conducting a preliminary breath test is an essential step in the process. This action helps to establish evidence of the driver's blood alcohol concentration (BAC) and can substantiate the officer's observations regarding the driver's level of impairment. The preliminary breath test, often referred to as a PBT, is a vital tool that aids in making an informed decision about whether to proceed with an arrest or further investigation.

This step is crucial not only for gathering evidence but also because it allows the officer to comply with legal standards and procedures regarding DUI enforcement. By obtaining a breath sample for analysis, the officer is following established protocols that help ensure that any subsequent charges are supported by reliable evidence.

Other actions, such as informing the driver of potential penalties, documenting behavior for a report, or issuing a warning, may be relevant in certain contexts, but they do not directly address the immediate need to assess the driver's intoxication level. Conducting a preliminary breath test is a proactive measure that aligns with the responsibilities of an officer addressing suspected DUI situations.
