SIGNIFICANCE OF BREATH TEST RESULTS
The results of breath analysis are presented digitally and may be interpreted as follows.
The following chart expresses BrAC in the measuring units of mg/L.
BrAC (mg/L) SIGNIFICANCE
0.05 Not associated with a positive measure of alcohol
0.10 Not necessarily indicative of alcohol consumption
≥0.25 Positive alcohol control and unsafe to drive a vehicle
BrAC readings up to 0.05 mg/L may appear from naturally occurring substances in the
body and are not associated with a positive measure of alcohol.
Readings up to 0.10 mg/L may occur from alcohol contamination from foods,
beverages or medicines and are not necessarily indicative of alcohol consumption.
Readings of 0.25 mg/L and greater are indicative of a level of alcohol at which it is
unsafe to drive a vehicle and may lead to a traffic violation.
