Illegal Police Stops (by DaytonDUI)

Protecting You From Illegal Police Stops! The Fourth Amendment of the United States Constitution protects you against unreasonable searches and seizures, which  includes being unlawfully or illegally pulled over or stopped by law enforcement.  An officer cannot simply pull you over based on a hunch or intuition.  When a police officer observes a traffic violation, he or she is justified in initiating a limited stop for the purpose of issuing a citation.  State v. Brickman(2001), 11th Dist. No. 2000-P-oo58, 2001 Ohio App. LEXIS 2575.  The legal standard applied to traffic stops is reasonable and articulable suspicion, which means that the officer has reason to...

DUI Blood Tests: Whole Blood vs. Serum/Plasma

Ohio Administrative Code 3701-53-03(A) sets forth the techniques and methods for determining the concentration of alcohol in blood, urine and other bodily substances.  Pursuant to that rule, Ohio allows for testing including gas chromatography and enzyme assays.  To challenge a blood test, it is important to know if the State has tested the blood as whole blood or as serum/plasma.  Operation with a concentration of alcohol is prohibited if the concentration in whole blood is equal to or exceeds .08%, R.C. 4511.19(A)(1)(b).  However, the prohibited concentration for whole blood is a concentration equal to or exceeding .096%, R.C.4511.19(A)(1)(c).  The high...

DaytonDUI, Defending a Breath Test Case

"I'll Huff and I'll Puff and Blow Your House Down" Did you know that your breathing pattern can significantly alter the concentration of alcohol on your evidential breath test?  According to scientific research, "[t]he subject's test manner of breathing just prior to providing breath for analysis can significantly alter the concentration of alcohol in the resulting exhalation." (Jones, 1982, Schoknecht, 1989) as cited in Physiological Aspecs of Breath-Alcohol Measurement, Alcohol Drugs & Driving Vol. 6, No. 2, A.W. Jones.Hyperventilation "...

The Prescription Drug Defense

While many people think of impaired driving as involving alcohol, we are increasingly seeing people accused of being impaired by prescription drugs.  Clients are surprised to learn that the same harsh penalties that apply to alcohol impairment also apply to prescription drug impairment.  You need an attorney who knows how to fight a drugged driving case.Drugged driving cases involving prescription drugs present a problem for law enforcement as indicators of prescription drug use are less apparent.  The standardized field sobriety tests are crude tools for detecting alcohol and may be useless in determining prescription drug impairment.  Challenging the officer's observations...

Intoxilyzer 8000 Is Unreliable!

Today, in State v. Heather Reid, Case No. TRC 1100716 in the Circleville Municipal Court, Judge Gary Dumm has ruled that "The State of Ohio cannot expect this Court to find the Intoxilyzer 8000 reliable when the State refuses to address known problems and explain why those problems can be ignored."The Court calls for independent laboratory testing to address the issues raised by the adoption of the Intoxilyzer 8000: RFI, sample size of the chamber, volume of the sample tested, possible operator manipulation of the results, possible CMI modifications of the software without the knowledge of ODH and slope detector...

DUI Science: Fat vs. Thin/Man vs. Woman/Young vs. Old

After consuming alcohol, will a fat person or a thin person have a lower BAC? Alcohol loves water and will move into spaces where water is the most prevalent.  Fatty portions of the body have a low water content and absorb little of the alcohol, while muscular portions of the body have a high water content and absorb much alcohol.  As it is carried to all parts of the body by the blood, the alcohol distributes itself in proportion to the water content of the various parts of the body.  It is the presumed relationship between the amount of alcohol in...

Morphine, Heroin and the Horizontal Gaze Nystagmus

In the past years, my office has seen an increase in the number of “drugged” driving cases we receive. While arrests for marijuana make up the vast majority of those cases, we are also seeing a dramatic rise in prescription drug cases along with traffic stops implicating harder drugs such morphine and heroin.As with other impaired driving cases, it is vital that you know the observations that would be consistent with impairment by that drug.  It is also vital that you determine if the “standardized field sobriety test” protocol adopted in Ohio is applicable in recognizing clues of impairment due...

Standardized Field Sobriety Tests

The Standardized Field Sobriety Test (SFST) is a battery of three tests administered and evaluated in a standardized manner to obtain validated indicators of impairment and establish probable cause for arrest. These tests were developed as a result of research sponsored by the National Highway Traffic Safety Administration (NHTSA) and conducted by the Southern California Research Institute. A formal program of training was developed and is available through NHTSA to help law enforcement officers become more skillful at detecting DWI suspects, describing the behavior of these suspects, and presenting effective testimony in court....

Reasonable & Articulable Suspicion

One of the major decision points in the OVI arrest process is the officer’s decision to remove a suspect from his or her car and conduct standardized field sobriety testing.  The officer is trained to arrive at this “decision point” by conducting an interview and using specific “pre-exit interview techniques” which include asking for two things simultaneously; asking interrupting or distracting questions; and asking unusual questions. (NHTSA Student Manual VI-4).  Additional techniques which an officer may employ include and Alphabet test (begin with E and end with P); a Countdown test (count out loud backward starting with 68 and ending...
