DUI Laws in Kentucky
What is DUI and what does it mean? KRS 189A.010 REVISED 10/01/00 
​DWI/DUI is an abbreviation of driving while under the influence of intoxicants (alcohol) or of any substance or substances which impair driving ability. Other substances can include illegal drugs, prescription drugs, inhalants such as glue, gasoline, spray paint etc., and/or over the counter medications. Kentucky's DUI law has an "Illegal Per Se" provision. "Illegal Per Se" (On the face of or by itself) means it is illegal to drive with a blood or breath alcohol content of 0.08 or higher.

Prosecutors no longer have to prove defendants were impaired if they are being tried for the per se clause of K.R.S. 189A.010. Requires that test be given within 2 hours of operation of motor vehicle for results to be admitted into evidence in per se DUI prosecutions.

*Operators can be convicted at levels lower than .08 based on other evidence which indicates impairment.
*Drivers under the age of 21 are deemed to be under the influence at .02 breath or blood alcohol level.
*Commercial vehicle drivers operating commercial vehicles are deemed to be under the influence at a breath or blood alcohol level of .04. Commercial vehicle operators may also be placed out of service for 24 hours for any detectable amount of alcohol or controlled substance in their system. KRS 281A.210

​Implied Consent
Implied Consent applies to any person who operates or is in physical control of a motor vehicle or a vehicle that is not a motor vehicle anywhere in Kentucky. Implied Consent means that when a person operates or is in physical control of a motor vehicle or a vehicle that is not a motor vehicle as defined by statute in Kentucky they have been deemed to have given consent to one (1) or more tests of blood, breath and urine, or combination for the purpose of determining alcohol concentration or presence of a substance which may impair one's driving ability. Only through a test of blood, breath or urine can alcohol levels be accurately measured. The breath test is precise and efficient in measuring BRAC.
It analyzes a breath sample to determine the amount of alcohol in the breath. A blood test measures the amount of alcohol in the blood. (Alcohol concentration means either grams of alcohol per 100 milliliters of blood or grams of alcohol per 210 liters of breath.)

License Suspension for Refusal to Take Alcohol or Subsequent Tests
It should be noted that all of the offenses listed below are for refusals within a five year period.
1st Offense 30 to 120 Days 3rd Offense 24 to 36 Months
2nd Offense 12 to 18 Months 4th Offense or subsequent-60 Months

Whether you are found guilty or innocent of the DUI charge, you will remain answerable for the Refusal and risk license suspension.
BAC - Stands for Blood Alcohol Concentration and refers to the amount of ethyl alcohol in the blood.

The metabolism of alcohol takes place in the liver. The body can burn approximately ½ ounce of alcohol in one hour. The liver eliminates approximately 90 percent of the alcohol from the body. The rest is eliminated through the lungs, perspiration, and urine. The only thing that sobers you up is time. If you drink or take substances which affect you physically/mentally...DO NOT DRIVE!!!
​Open Container Law
This new provision prohibits an open alcoholic beverage in the passenger area of a motor vehicle while on the public highways or right of way. To learn more about these laws, visit http://www.nhtsa.dot.gov/people/injury/research/OpenContainer/.

License Plate Confiscation and Ignition Interlocks for Repeat Offenders
Ignition Interlock Device
Drivers convicted of a second or subsequent DUI will forfeit their license plates to the courts during the period in which the driver license is suspended. The court may order an ignition interlock device to be installed on the violator's vehicle after the driver serves a statutory suspension period. The ignition interlock device prevents a driver from operating that vehicle if the driver's BAC is .02 or greater.
