During a DUI investigation, the officer will in most cases ask the driver to take a breath or blood alcohol test to determine the amount of alcohol or drugs in the driver's system. The driver's blood alcohol concentration (BAC) or the concentration of drugs in the driver's system is often used as evidence to prove a DUI in court.
This article gives an overview of the law requiring a driver to submit to DUI chemical testing and the consequences of an unlawful refusal.
Kentucky's implied consent law basically says that any person who drives in Kentucky thereby agrees to take one or more chemical tests if requested to do so by an officer. However, the driver is required to take the test only if the officer has reasonable grounds to believe the driver was in violation of the state's DUI laws. These chemical tests may include breath, blood, or urine samples.
Evidentiary uses. It may be more difficult for a prosecutor to prove a DUI without a valid chemical test. But the fact that a driver refused to submit to testing can actually be used against him or her at trial. Although a refusal doesn't exactly prove intoxication, prosecutors often argue that the person refused testing to hide intoxication.
Enhanced penalties. Refusal of a lawfully requested chemical test is not a crime in Kentucky but can be used to enhance the penalties of a DUI. DUI convictions involving refusals carry twice the normal minimum mandatory jail time. Any person who refuses testing and is charged with a DUI will not be permitted to plea to a lesser offense.
License revocation. If the driver refuses testing and is not found guilty of DUI, the judge can still revoke the driver's license if the prosecutor can show that reasonable grounds for the DUI arrest existed and the driver refused a lawfully-requested test. If the prosecutor is successful, the judge will revoke the driver's license as though the driver had been convicted (there's a 30 day to 36-month revocation depending on how many prior offenses the driver has).
Restricted license. Similar to how it works with a DUI conviction, persons with a revoked license for refusing a BAC test are eligible for a temporary restricted license to drive for certain purposes like work, school, and treatment. But the court will order the driver to install and use an ignition interlock device (IID) as a condition of the restricted license.
If you've been arrested or cited for refusing a chemical test in Kentucky, it's a good idea to get in touch with a DUI lawyer. DUI law is complicated and every case is different. A qualified DUI attorney can tell you how the law applies to your case and help you decide on the best course of action.
