What Is Kentucky’s Implied Consent Law?
Under KRS 189A.103, Kentucky drivers are deemed to have given their consent to chemical testing if they are arrested on suspicion of impaired driving. This consent includes breath, blood or urine tests but does not apply to preliminary breath tests done before arrest (usually at the roadside).
What Are The Consequences Of Refusal In A DUI Case?
When you refuse a breathalyzer in Kentucky or another chemical test to determine your blood alcohol content (BAC), there are immediate and serious consequences. As such, the police are required to inform you that refusal will result in the immediate suspension of your driver’s license until your DUI case is resolved. You will also be ineligible for a hardship license.
In addition, refusal of testing can be used as evidence against you in court and can result in enhanced penalties, including double the mandatory jail time, if you are later convicted of the DUI charge.
The 20-Minute Observation Rule And Independent Testing Rights
In Louisville, Kentucky, breathalyzer results must follow the 20-minute observation rule. Officers are required to observe the individual continuously before administering the test. Any violation of this rule can affect the reliability of the results and allow them to be challenged in court.
Additionally, DUI blood test laws in Kentucky allow individuals to request an independent blood or urine test after the state conducts its test. We help ensure that this option is not ignored and that any failure to honor it is brought forward in your defense.
