What is one possible outcome of administering a PBT?

The administration of a Preliminary Breath Test (PBT) serves a specific purpose in evaluating a driver's impairment due to alcohol consumption. When a law enforcement officer administers a PBT, it provides quantitative data regarding the presence and concentration of alcohol in the individual's breath, which can help establish whether the driver is under the influence of alcohol at the time of the stop.

This test measures the breath alcohol concentration (BrAC) and can act as a useful indicator of impairment, supporting the officer’s observations and physical tests conducted during the Standardized Field Sobriety Test (SFST). If the PBT result indicates a level above the legal limit, it can serve as evidence to confirm the chemical basis of the subject's impairment, reinforcing the case for further action such as an arrest.

The other options presented pertain to administrative matters or records which are not relevant to the immediate assessment of impairment that the PBT is designed to gauge. For instance, confirming a driver's license status or vehicle registration involves checking the identity and legal standing of the vehicle and driver rather than assessing alcohol impairment. Similarly, reviewing previous driving records does not provide real-time data on the current state of impairment. Thus, the primary function of the PBT is closely tied to determining whether alcohol is
