Driving under the influence, or D­U­I, means driving or operating a motor vehicle in a public place while intoxicated. It is usually a misdemeanor. This offense can also be defined as a D­W­I or driving while intoxicated, or an O­W­I meaning operating while intoxicated. All three charges are punishable to differing degrees depending on each state's laws. If you are arrested for driving under the influence, you may be asked to take a blood, urine, or breath test. If at all possible, try to speak to your attorney before taking such a test. However, some police departments require that you be tested before you are allowed to make a phone call. The decision whether or not to take the test may be an important one. You do have the right to refuse the test. However, your refusal could cause you to lose your driver's license for up to one year. Your refusal will also be made known to the court. The police will forward all evidence, including the results of the blood alcohol test, to the prosecutor's office where a decision about whether to prosecute will be made. If they decide to prosecute, you should obtain a good lawyer with considerable experience in this field. Depending on the court proceedings, officer testimony, and test results, you may be charged with a D­U­I, D­W­I, or O­W­I. Usually these charges incur large fines, jail time, and community service along with the suspension of driving privileges. For more information, contact an attorney or law enforcement agency.
