What type of evidence does a successful PBT result provide?

The successful result of a Preliminary Breath Test (PBT) provides circumstantial evidence for establishing probable cause. This means that while a PBT can indicate that a driver has consumed alcohol, it does not serve as definitive proof of intoxication or guilt. Law enforcement officers often use PBT results to develop a reason to take further steps, such as making an arrest or conducting a more comprehensive evaluation of a driver’s condition.

Circumstantial evidence is crucial in the context of assessing someone's intoxication since it helps build a case based on the overall circumstances rather than providing irrefutable proof. This is particularly important in legal situations where a variety of factors, such as behavior, physical condition, and other observations, are taken into account to support the determination of probable cause for further investigation.

In contrast, conclusive evidence of guilt or direct evidence of drug use, as suggested by other options, would imply a level of certainty that is not afforded by the PBT results alone. Similarly, PBT results are not considered uncontested evidence in court as they can often be challenged or require corroboration with other forms of evidence to support the case fully.
