BREATHALYZER TESTS Meaning and
Definition
-
Breathalyzer tests, also known as breath alcohol tests or breath tests, are a commonly used method to measure the level of alcohol in a person's breath. It is a portable, handheld device that analyzes the alcohol content present in an exhaled breath sample, providing an estimate of the individual's blood alcohol concentration (BAC).
Using a breathalyzer test is a quick and non-invasive way for law enforcement officers to determine if a person has consumed alcohol and whether they are potentially driving under the influence (DUI) or driving while intoxicated (DWI). It is typically utilized during traffic stops or at sobriety checkpoints.
The device operates by utilizing the principle of alcohol concentration in the breath being proportional to the alcohol concentration in the blood. The breathalyzer measures the amount of alcohol in the breath sample provided by the individual, and this measurement is then converted into an approximate BAC reading.
Breathalyzer tests play a critical role in enforcing alcohol-related laws, promoting public safety, and deterring drunk driving. They provide law enforcement with a practical means to assess impairment and make informed decisions about whether to take further action, such as administering other tests or making an arrest.
It's important to note that while breathalyzer tests are widely used and have become a standard tool for assessing alcohol intoxication, they are not infallible and their accuracy can be influenced by various factors. Therefore, breathalyzer results may be subject to challenge or confirmation through additional, more precise testing methods.

Etymology of BREATHALYZER TESTS
The word "Breathalyzer" is a portmanteau, combining "breath" and "analyzer". Its etymology can be traced back to the early 20th century. In 1927, a scientist named Dr. Robert Frank Borkenstein developed a device to measure the alcohol concentration in a person's breath, which he initially called the "Drunkometer". Later, in the 1950s, he further improved the device and renamed it the "Breathalyzer".
The term "Breathalyzer" became a genericized trademark for all breath-testing instruments used to determine blood alcohol concentration (BAC). It is important to note that "Breathalyzer" specifically refers to devices manufactured by the company originally founded by Dr. Borkenstein, now known as "Intoximeters". However, the term has been widely adopted to describe similar devices produced by various manufacturers.
