The Laws About DUI And The Necessary Approaches To Find Out If Someone Is Driving Under The Influence Of Alcohol

by on July 6, 2010

If someone is in physical control of a motor vehicle, and is also under the influence of alcohol, this is called DUI or Driving Under the Influence. When a driver is DUI, this can be deadly because their ability to drive is impaired.

California is one state with strict DUI laws. You cannot drive under the influence in this state. It is illegal to drive a car, pilot a boat, or pilot a plane if you are intoxicated or under the influence of drugs. In fact, because of the extreme nature of the safety concerns when someone is flying a plane, there are very strict piloting laws on the books.

Being under the influence makes you unable to safely drive your vehicle. At as low a blood alcohol content (BAC) as 0.02%, you already have impairment in your ability to do two things at the same time (like steer and brake). When we increase the BAC to 0.08%, a driver will be unable to safely manage their vehicle and will pose a major danger if they attempt to drive.

That is why California instituted a law in 1990 that makes it illegal to drive with a BAC of 0.08% or more. If you are in California, and you are found to have driven with a BAC of this much or more, you will be arrested and charged with DUI.

California is not the only state to establish this rule. Additionally, in these states the law enforcement personnel are specially trained to be able to spot and assess drivers who may be impaired.

Law enforcement personnel use a variety of tools to accomplish this, including field sobriety tests (FST). In an FST, an officer will assess someone’s movement and reflexes in order to gauge impairment. It cannot identify the legal limit for DUI however. This requires knowledge of the BAC.

The most accurate measure of BAC comes via blood test or urine sample. A more commonly used method is to measure the alcohol via the person’s breath. The tool that is used for this is called a Breathalyzer.

When you consider DUI fatalities over time, you can see a statistically significant decrease since the 0.08% BAC law has been used.
