Florida DUI Penalties

• A fine between $2,000 and $5,000
• At least 30 days in jail, but could be sentenced up to 5 years. Regardless of the full sentence, 48 consecutive hours of confinement will be required.
• Driver's license revocation lasting 10 years
• Ignition Interlock Device must be installed on your vehicle for at least 2 years
• Your vehicle will be impounded for at least 90 days, not overlapping with any time spent in jail

How much will a third DUI cost you if it's been over 10 years? If more than 10 years have passed, your third DUI conviction will be classified as a First Degree Misdemeanor and the penalties will be less severe.

If you have no prior convictions within a 10-year period, you may not face any jail time, but the maximum sentence is 12 months. You will likely face a fine between $1,000 and $2,500 and will need to have an ignition interlock device installed in your vehicle for 2 years.

Fourth-Time DUI Penalties

The penalties for a fourth DUI offense include a minimum fine of $2,000, up to five years in prison and a mandatory permanent driver's license revocation. Unlike for lessor offenses, you will not be eligible to apply for a hardship license for driving to and from work. You would also have a felony conviction on your criminal record, which could make it exceedingly difficult for you to find suitable employment.

About the Ignition Interlock Device

Ignition interlock devices are used as a tool for monitoring a convicted DUI offender's driving, by requiring the individual to provide a clean breath sample before starting the car and at random intervals while driving.

If you have alcohol on your breath the vehicle will be immobilized and the failed test will be reported to your probation officer. The Florida DHSMV reports that six months of ignition interlock device use can cost over $600 in expenses for installation and monthly calibration and monitoring.
