Breathalyzer versus Blood Tests in Drunk Driving Cases

The most frequently used test in drunk driving cases is the breath test, or Breathalyzer test. The breath test is used more frequently that urine or blood tests to test for the blood alcohol level because it is less intrusive and the apparatus is easily portable and convenient to use, even in the field. Because blood tests are universally relied upon as stronger evidence than breath tests, the prosecution will seek it whenever it can. In many states, a blood test may only be administered in cases involving death or serious bodily injury, or when the motorist required medical treatment and the administration of a breath or urine test was impractical or impossible. ¤Although a motorist may refuse this test, the refusal is usually admissible in evidence against the motorist at the administrative or judicial hearing.

Criminal Offense of Failure to Assist an Injured Person

Motorists involved in any type of motor vehicle accident where personal injury or death occurs are required to remain at the scene until police arrive. All states have statutes setting out certain procedures a motorist must follow after involvement in a collision causing death or injury. Moreover, the statutes treat the term "accident" or "collision" to include all automobile collisions, intentional as well as unintentional.

Double Jeopardy Defense in DWI/DUI Cases

Drunk driving defendants have challenged the constitutionality of the states' dual use of administrative license suspension (ALS) statutes and criminal driving while intoxicated (DWI) prosecutions with the so-called Double Jeopardy Drunk Driving defense.

Elements of DUI/DWI Offenses Involving Operation of a Boat

All states have BUI laws making it unlawful to operate any vessel while under the influence of alcoholic drugs, certain controlled substances, and drugs. On navigable waters of the United States, federal law provides for a civil fine of not more than $ 5,000 for any person operating a vessel under the influence of alcohol or a dangerous drug. Alternatively, the boater may be charged with a class A misdemeanor.

Elements of DUI/DWI Offenses Involving Operation of Aircraft

It is unlawful for any person who is under the influence of intoxicating liquor or drugs to drive, operate, or take actual physical control of a motor vehicle in a public place. This is commonly referred to as driving under the influence (DUI) and operating under the influence (OUI). This offense also applies to operating aircraft, and many states specifically list an aircraft as a type of "vehicle" included in the applicable vehicle code. Other states cover the operation of an aircraft in a separate section within its code.
