What do PBT results help to corroborate?

PBT results, which refer to Portable Breath Test results, play a significant role in confirming or supporting an officer's decision to make an arrest. When a law enforcement officer conducts a PBT, it provides immediate feedback on a driver's blood alcohol concentration (BAC) level. If the PBT indicates that a driver has surpassed the legal BAC limit, it provides substantial evidence that can validate the officer's judgment regarding impairment.

This corroboration is crucial in the context of a traffic stop, as it reinforces the observations the officer has made during the Standardized Field Sobriety Tests and other indicators of impairment. Consequently, having the PBT results supports the officer’s decision to proceed with an arrest, making it an essential tool in DUI enforcement.

The other options, such as driving history, field appearance, and blood alcohol content, while related to the overall context of DUI enforcement, do not specifically focus on the direct role PBT results play in validating the arrest decision.
