A THC breathalyzer could revolutionize roadside sobriety testing for drivers suspected of impairment. This can be measured through both a breathalyzer test or a blood test. After Gaetz was arrested, he refused to take a breathalyzer test. His Breathalyzer used chemical oxidation and photometry to determine alcohol concentrations. Barry was then taken to the U.S. Capitol Police station for a breathalyzer test. Knox is shown taking a breathalyzer test and is subsequently placed on suspension. At the police station, Cloyd and Hughes both consented to a breathalyzer test. In 2001, Northwest fired a pilot who failed a breathalyzer test after a flight. One major application for this reaction is in old police breathalyzer tests. A breathalyzer is a device for estimating BAC from a breath sample. Trailers are used to conduct breathalyzer testing. The first Canadian test of the breathalyzer was in Ontario in 1954. Larger breathalyzer devices found in police stations can then be used to produce court evidence. He was twice administered a breathalyzer and twice blew a 0.000. Some designated driver services have formed a special bond between breathalyzer manufacturers/distributors.
