When the operator of a vehicle and is pulled over by the police (or encounters police after being involved in an accident), the officer is permitted to conduct a breathalyzer test if he or she suspects that the person was driving the vehicle while intoxicated. The main function of a breathalyzer test is to measure an individual's blood alcohol content (BAC). Because it is not practicable for an officer of the law to check a motorist's blood alcohol content level at the scene by drawing a blood sample, the breathalyzer was created as a way to simply measure someone’s blood alcohol content level easily and instantaneously.
Police officers have been utilizing breath alcohol testing devices since the 1940s. The breathalyzer, which is the most frequently used testing device today, was created in 1954. It senses and measures the level of alcohol on an individual’s breath with the use of a chemical reaction. A Breathalyzer test kit consists of many vials of chemicals of differing colors that go through color changes when they come into contact with alcohol. The different color changes signify the amount of alcohol.
