Having a passenger under 18 in the vehicle raises a Florida DUI the same way a 0.15 reading does. Under section 316.193(4), the fine and jail rise and a six-month ignition interlock becomes mandatory even on a first conviction. It also carries a collateral risk that a high reading does not, because an arrest with a child in the car can trigger a separate child-welfare process.
| Penalty | What the law provides |
|---|---|
| Fine, first offense | $1,000 to $2,000, against $500 to $1,000 without the enhancement |
| Jail, first offense | Up to 9 months, against up to 6 months without it |
| Ignition interlock | Mandatory minimum 6 months on a first conviction |
| Who counts as a minor | A passenger under 18 years of age at the time of the offense |
| Higher offenses | The enhanced fine and jail figures carry up the ladder to second and third offenses |
Driving under the influence with a person under 18 in the vehicle is an enhancement under section 316.193(4), Florida Statutes, parallel to the 0.15 enhancement. Program terms last verified June 2026.
The same enhancement path as a high reading
The minor-in-vehicle enhancement runs parallel to the 0.15 enhancement. Either one moves a first DUI into the higher fine and jail range and adds the mandatory interlock, and both carry up the ladder to second and third offenses. The difference is that the minor enhancement does not carry the section 316.656 plea bar that a 0.15 reading does, so a reduction is not automatically foreclosed, though prosecutors tend to hold a firmer line when a child was present.
The collateral risk to watch
Beyond the criminal penalties, an arrest with a child in the car can draw a child-protective inquiry that runs separately from the criminal case. That second track can carry its own consequences and its own deadlines, which is why a DUI with a minor needs careful handling from the first day rather than treating it as just a heavier first offense.

Minor in vehicle questions
What is the penalty for a DUI with a child in the car?
Driving under the influence with a passenger under 18 triggers the same enhancement as a 0.15 reading under section 316.193(4). On a first offense it raises the fine to $1,000 to $2,000, raises the jail ceiling to nine months, and makes a six-month ignition interlock mandatory. The enhanced figures also carry up to repeat offenses.
Who counts as a minor for this enhancement?
A passenger who was under 18 years of age at the time of the offense. The enhancement is about the presence of that minor in the vehicle, and it applies on top of the base DUI penalties for the offense level involved.
Does a DUI with a minor lead to a child welfare case?
It can. Beyond the criminal enhancement, an arrest with a child in the car can draw the attention of child protective authorities, which is a separate process from the criminal case. That collateral risk is one reason these cases need careful handling from the start.
Can a DUI with a minor be reduced?
It is harder than a standard first DUI because the presence of a child makes prosecutors less flexible, but it is not automatically barred the way a 0.15 reading is under section 316.656. Whether a reduction or diversion is realistic depends on the facts, the reading, and the State Attorney.
How does the state prove a minor was present?
The state relies on the officer's observations, statements, and any documentation of who was in the vehicle and their age. The presence and age of the passenger are facts the defense can examine, the same as any other element of the enhancement.

Florida DUI penalties are set by section 316.193, Florida Statutes, and related statutes including sections 322.28, 322.271, and 316.656.

Every case turns on its own facts, and past results do not guarantee a similar outcome.
