Breath analysis is the most common method of testing for blood-alcohol content in use today. Personal breathalyzers estimate the concentration of alcohol in the body by measuring the amount of alcohol exhaled from the lungs.
Drivers can pass a roadside sobriety test and still be breaking the law. It is illegal to operate a vehicle, boat or aircraft when the blood alcohol level exceeds the legal limit.
Notice the test for impairment does not take into account the abilities of the driver. In most states, a criminal offense occurs where the concentration of alcohol exceeds 80 mg per 100 ml of blood (.08% BAC), without having to prove impairment.
So police officers use some of the latest technology to detect alcohol levels in suspected drunk drivers and remove offenders from the roads.
Breath alcohol tests are proven, reliable, efficient and helpful.
Having the correct information is so vitally important when making the dangerous and potentially expensive decision to drive after a few drinks.
We all rely on speedometers to keep our driving speed within the legal limits. But, what if cars came without speedometers, and the police still enforced speeding laws with high tech radar guns?
It would be really difficult to tell what a particular speed feels like if you never had your speed tested, nor had any previous experience with 30 mph for example.
Yet, not many people really know what .05% or .08% BAC feels like, unless you have a way to get it measured.
How can an ordinary person be expected to obey the law, unless they have personal breathalyzers to measure their levels of intoxication?

Nobody wants a DUI conviction or its consequences -- you risk a night in jail, thousands of dollars in fines and legal fees, the embarassing publication after a trial.
If you are not sure you had better not drive, just play it safe and call a cab.
