Felony DUI Law Coming to Colorado?

Last year, Senate Democrats in Colorado killed a bill that would have made repeat DUI offenses a felony offense in Colorado, much to the surprise and chagrin of the proposed law’s supporters. But now a Weld County state representative is trying again, with a new bill that, if passed, would classify a charged driver’s third DUI in seven years as a class 4 felony.  A class 4 felony carries a 2-6 year prison sentence followed by a mandatory 5 year period of parole.  The ...

The Oldest Question: Do You take a Test?

Well, it may not be the oldest question, but it may be the most important. Since the 1940’s and the onset of cheap blood alcohol testing, it is one that lawyers and defendants must initially face following a DWI arrest. Should you or shouldn’t you take the test? The answer to this, like everything else in law, is it depends. Like predicting the weather, the answer to this question turns on a variety of factors. While much of what I ... Read More »

How a DUI/DWI Will Impact Your Travel Plans to Canada

Under current Canadian law, a DUI or DWAI conviction in Colorado (or elsewhere in the U.S.) may make you a “criminally inadmissible person.” An “inadmissible person” cannot visit or stay in Canada because they have been convicted of certain crimes in, or outside of, Canada. Despite meeting eligibility requirements, foreign individuals from any country may still be criminally inadmissible to Canada due to previous criminal conduct, or the criminal conduct of their dependents. In particular, if you are convicted of a ... Read More »

Breathalyzer Phone Apps Shouldn’t Be Relied On!

Like all states, Michigan’s legal limit is .08.  This means that if you take a breath test, and the breath test shows .08 or more, you can be convicted on this basis alone – even if you were driving just fine. Of course the police can also test your blood or urine. Here is what the judge would tell the jury about your breath test: If you find that there were 0.08 grams or more of alcohol per 210 liters of ... Read More »

Do Breathalyzers Measure Alcohol?

Breathalyzers don’t actually measure alcohol. That’s right.  What they actually detect and measure is any chemical compound that contains the methyl group in its molecular structure.  There are thousands of such compounds — including quite a few which can be found on the human breath. And this machine that determines a person’s guilt or innocence in a DUI case will “see” all of those chemicals as alcohol — and report a falsely high blood-alcohol concentration (BAC). Most breath machines used ... Read More »

More Problems with the Alcohol Testing Program in Florida

For years, the State of Florida Alcohol Testing Program, a division of the Florida Department of Law Enforcement has been denying that they possessed the software used in the Intoxilyzer 8000 in Florida.  When the Intoxilyzer 8000 first starting being used in Florida the software in it was version 8100.26.  Many judges throughout the State ordered FDLE to disclose the software in their possession.  In response the State allegedly sent all copies of the software back to CMI, the manufacturer ...

Drunk Driving Defense Requires Competent Experts

If your life has been suddenly disrupted by a Michigan drunk driving arrest, then be sure to hire a DUI lawyer specialist who also has access to the Nation’s top DUI experts.

Proposed Changes to Florida’s DUI Laws May Limit Defenses.

House Bill 299 is a 96 page proposed amendment to Florida DUI Laws. There are numerous proposed changes which will be discussed in future posts, but the subject of today’s post is the proposal that makes it illegal to have a breath or blood concentration of .08 or higher at any time after driving. According to House Bill 299 a person can be convicted of DUI if, “[t]he person has an alcohol concentration of .08 or more grams of alcohol ... Read More »

Breath Alcohol Doesn’t Exist!

An essential fundamental of experimental science is that if something can’t be measured, it does not exist. One noteworthy scientist, Mr. William H. George, phrased it this way: “[S]cience is measurement. If I cannot make measurements, I cannot study a problem scientifically.”[i] Understanding this primary tenant, a follow-up question might be; how precise must a measurement be in order to study something scientifically, and furthermore, if the thing being studied is not measured precisely, then does it exist at all?  ...

Colorado DUI Enforcement: The Myths Behind the Numbers

Law enforcement officials in Colorado say they made 1,342 DUI arrests between August 16 and September 3 — a time period during which they typically ramp up enforcement efforts in preparation for Labor Day Weekend, reports Just to put this in context, because it sounds like a lot, this works out to an annual number of 24,973 arrests.  The 10-year average is usually between 30,000 and 35,000 consistently. 1,300 arrests for 100 agencies over 19 days is two arrests every three ...
