A conviction for driving under the influence in the state of Kentucky may result in the court-ordered installation of an ignition interlock device in each of the offender’s motor vehicles. In addition to this, the penalties for DUI offences vary depending upon the driver’s record.
| Offense | Fine | Jail Time | Suspension Period |
| 1st | $200 to $500 + $375 service fee | 48 hours | 30 to 120 days |
| 2nd | $350 to $500 + $375 service fee | 7 days – 6 months | 12 – 18 months (or earlier with an ignition interlock device) |
| 3rd | $500 to $1000 + $375 service fee | 30 days – 12 months | 24 – 36 months (or earlier with an ignition interlock device) |
| 4th | At the court’s discrention | 120 days or more | 60 months (or earlier with an ignition interlock device) |
There are some other things to note about Kentucky’s DUI laws:
- An offender who has 2 or more previous DUI offences must surrender their license plates to the state while serving their suspension.
- Even after the suspension period is over, a driver using an ignition interlock system may be required to continue using it for an addition 6 to 30 months.
- For especially egregious DUIs, the penalties will likely be in excess of what you find above.
- An offender may also be required to seek treatment for substance abuse.
