Numbers to know

3 questions from the Kentucky practice test

1. 1. Under Kentucky’s implied consent law, what has a driver implicitly agreed to do when operating a vehicle?

   1. Take a lawfully requested test of blood, breath, urine, or a combination
   2. Refuse every chemical test unless arrested
   3. Take only a roadside breath test
   4. Submit only to a test requested in the licensing state
   Show answer

   Take a lawfully requested test of blood, breath, urine, or a combination. Operating a vehicle carries implied consent to a lawfully requested test of blood, breath, urine, or any combination of those tests. The agreement is broader than a roadside breath test and does not depend on where the driver received a license. Refusing is not a protected default; the manual says refusal may lead to license suspension and may be used as evidence. When stopped on suspicion of impairment, identify whether the request is lawful and understand the consequences before responding.

2. 2. What penalties does Kentucky list for a first DUI conviction within ten years?

   1. A $200 to $500 fine, 48 hours to 30 days in jail, and a 4 to 6 month suspension
   2. A $1,000 fine and 1 year in jail
   3. A warning and a class
   4. A 30 day suspension only
   Show answer

   A $200 to $500 fine, 48 hours to 30 days in jail, and a 4 to 6 month suspension. For a first alcohol conviction within a ten year period, the Kentucky manual lists a fine of $200 to $500 plus court costs, 48 hours to 30 days in the county jail, and a license suspension of four to six months. Under KRS 189A.010 the court may impose the fine, the jail term, or both. A driver under 18 may get a longer suspension. A $1,000 fine with a year in jail overstates the first offense, and a warning or a 30 day suspension understates it.

3. 3. At what BAC within two hours of driving does Kentucky treat a DUI as aggravated?

   1. .08 or higher
   2. .15 or higher
   3. .02 or higher
   4. .10 or higher
   Show answer

   .15 or higher. One aggravating circumstance is an alcohol concentration in the blood or breath of .15 BAC or higher within two hours of stopping driving, which brings mandatory jail time. Point zero eight is the ordinary DUI line for adults, and .02 is the under 21 limit and the interlock setting. Point ten is not in the list. Other aggravating circumstances include going more than 30 mph over the limit and carrying a passenger under 12.
