I've written before about how your body naturally produces alcohol which can give false-positives to a breathalyzer machine, but there are other things that can get you into trouble with a breath-alcohol machine.

Breathalyzer machines don't actually detect alcohol at all, they detect the presence of the methyl group in the compound, which basically means false positives happen more often than you might think. There are thousands of things that contain the methyl group, and at least 10% of them have been found in the human mouth.

Scientists have been running tests to see what foods can give a false-positive to a breathalyzer machine. In one such experiment, test subjects blew a .05 BAC after eating bread.

A man in Australia was recently arrested for a DUI after eating at an ice cream shop. The ice cream went straight into his blood stream, and he blew a .018 on the breath-alcohol machine. Since he knew he did not consume any liquor, he brought some ice cream to court to prove that was the cause of his false-positive test.

Experts said consuming some foods or drinks before breath tests can cause a false positive reading. It is recommended that that test subjects wait at least 15 minutes in between eating and blowing into the machine. This is also the reason police in Colorado have to wait 20 minutes to administer a breath test, so they cut down on false positives.

Just remember, if you eat some bread ice cream, take a taxi home so you don't get in trouble for driving under the influence!

Some guy had a few drinks at a bar and decided to drive home one night. He his something on his way home, what he "thought was a large deer". He cleaned his car the next day and did some Google search to find out if repair shops were required to contact the police if they're suspicious of anything.

This guy actually hit a woman who was walking home from work, and killed her instantly. He didn't even bother to stop and see what he hit. When police announced they were looking for a red Jaguar, he still didn't call police because he had a black jaguar. He plays dumb, but he's smart enough to find out if repair shops talk to police. If he was really didn't think he did anything wrong he wouldn't have made those searches.

I usually write about ways to try to beat a DUI charges, but it's different when you kill somebody while you're driving drunk. That's also why I always say you should get a cab or call a sober friend if you're out drinking. Walk to a bus stop or a near-by hotel, or sleep in your car until you're sober.

The worst part of this accident, other than it being completely avoidable, is that he only got a 3 year sentence for not stopping to see what he hit, "fleeing a crime scene". No matter how dumb this guy pretends to be, he knew he did something wrong that night and he deserves to spend more than 3 years in prison for killing somebody.

During the trial, the prosecutor told the jury: "And I think what he did afterwords is extremely telling, also, the computer searches and Web pages. Auto parts, auto dealers out-of-state; auto glass, Las Vegas; auto glass reporting requirements to law enforcement, auto theft... The defendant didn't offer you any explanation for the auto theft, one, and he had a series of excuses for the other ones. But when you put them all together, the only reasonable conclusion was he was going to try to get the car fixed somewhere else far away so he wouldn't be found out, he was going to try and avoid having anything reported to law enforcement".
