The technology is sound, and is almost always followed up with a blood test once the guy gets to jail. For people who come into the ER following an accident, blood is ALWAYS taken for a BAC and drugs of abuse.
The problem is defense loyiz who will throw whatever they can, regardless of how ludicrous it is, up against the wall, hoping some of it will stick.
If you blow the field sobriety test, blow the breathalizer and blow the blood test, you have no defense. Pay your fine, lose your license and watch your insurance rates (assuming you can find another insurance company to issue you a policy) go into low orbit.
Bull shit
And lose your security clearance, lose your job, lose your chances of finding another job. Lose your home (because you lost your job). Lose your car. Possibly lose your kids (if you're a custodial parent). Lots to lose if you get busted driving drunk. That's why people are fighting it a lot more these days. There's so much more at stake than there used to be.
It used to be a DUI was a bad weekend. Face the music, pay a fine and bum a ride for a few weeks. These days it is a career killer and a major, life-changing conviction that closes a lot of doors.
I'm not arguing good or bad, just that it is what it is.

Yeah Right ; Tell that to every diabetic teatotaler who blows a violation...
The tech is not sound. Independent peer-reviewed science says the machines are unreliable. In fact, the underlying basis for establishing BAC is flawed.
Also, FST’s are bogus as well. Even the DOT research shows cops find 60% of 0.00 BAC folks impaired.
Lowering the DUI BAC level is causing all the defense bar push back. What states should concentrate on is locking up the high BAC drunks those folks are ones that kill people.
