How Breath Testers are Used

BACtrack offers the most comprehensive line of Australian Standards Certified personal breath testers that are portable, compact and simple to use.

How to use Breath Testers

Alcohol breath testers use the quantity of alcohol in a person’s breath to assess the percentage of alcohol in a person’s blood, commonly known as Blood Alcohol Concentration (BAC). Here’s how to do it: 

  • When someone consumes alcohol, it passes through the larynx and enters the stomach and small intestine, swiftly being absorbed into the bloodstream. The BAC of an individual who has consumed an alcoholic beverage may be determined within minutes through breath testers.  
  • The liver then breaks down around 90% of the alcohol you ingest; the remainder, through urine and exhalation. And the breath testers will calculate the BAC based on the level of alcohol in the breath. 

When can a Police Breath Test You? 

The law enforcement officers have the authority to administer any breath testers if they have reasonable grounds to think you have: 

  • Been involved in a car accident 
  • Broken a law in which driving was a factor 
  • Acted in a way that suggests your driving skill is compromised (for example, swaying and speeding) 

Refusal of an Alcohol Breath Test

Drink driving is illegal in all Australian states and territories if you have more than 0.05% BAC level of alcohol in your bloodstream. An alcohol breath test administered by a police officer is the primary form of evidence used in trials for drink driving offenses to establish that an offender had a BAC of 0.05% or more at the time of the incident. In addition, refusal to take a breath alcohol test when necessary is illegal, but subject to specific exceptions. The Road Traffic (Miscellaneous) Regulations 2014 and The Road Traffic Act 1961 provide the regulations for performing a breath test. 

Anybody, not only police officers, may use breath testers. So, get your BACtrack portable breath tester now to make the correct decision about driving after a night out on the town. You’ll have peace of mind knowing that our products will deliver nothing less than outstanding results every time.
