Breath analyzing is the most popular form of testing for blood alcohol content in use today. Personal breathalyzers measure within a good estimate on what this level is by simply measuring the level of alcohol in one’s breath. You exhale into the device and it gives you an estimate reading.
In the past, when a drive was stopped for suspicion of DUI, the officer would preform a ’sobrity test’.
These would include having the drive perform functions such as walking in a straight line with one foot directly in front of the other, or placing their arms stretched out and then reaching in and touching the tips of their nose.
Unfortunately this is nothing more than a primitive way of detecting someone’s ability to drive. Essentiately these past tests would not be able to detect if someone was driving over the legal BAC limit.
If someone is more used to drinking, they would be able to handle more amount of alcohol and would be able to perform these functions with greater ease.
This is hardly fair to everyone. With the introduction of the breathalyzer these test are still performed but not as often, and not as the only source of detecting.
With the introduction of personal breathalyzers, the power to detect BAC levels is put into the persons hands and gives them a tool to better judge their BAC level.
This introduces a level of fairness considering your can be charged and arrested for drunk driving without knowing for sure, or having an easily accessible way of knowing if you are doing it or not, outside of guessing.
It’s very simple to pick up a small, compact keychain breathalyzer online and doing so can really save you a lot of hassle if you get caught with a BAC that is over the legal limit.
If you think of it on the same level as speedometers in our cars telling us how fast we are going, it makes sense that with that knowledge if we go over a certain speed we are capable of getting a speeding ticket because of the officers radar gun.
If we didn’t have speedometers in our car we would simply have to guess what speed and could very easily mistake it, and when we were pulled over and given a ticket it would hardly be fair since we had no way of even knowing we were breaking the law in the first place.
Personal breathalyzers are the same thing, only with detecting blood alcohol content, and not the speed of how fast we are driving.
