A breathalyzer is a device used to estimate a person's blood alcohol concentration (BAC) from a breath sample. Here's a breakdown of key information:
* How it works:
* Breathalyzers measure the amount of alcohol in exhaled breath.
* Because there's a correlation between alcohol in the breath and alcohol in the blood, the device can estimate BAC.
* Essentially, the device measures the amount of alcohol in the lungs, and then calculates the corresponding blood alcohol level.
* Use in DUI enforcement:
* Law enforcement officers use breathalyzers to determine if a driver is operating a vehicle under the influence of alcohol.
* The results of a breathalyzer test can be used as evidence in court.
* The legal BAC limits vary by location.
* Key points:
* Breathalyzers provide a relatively quick and non-invasive way to assess alcohol impairment.
* They are a common tool in DUI/DWI (driving under the influence/driving while intoxicated) enforcement.
* It is important to know that the results of these test can have legal implications.
I hope this information is helpful.
