What Happens if You Are Accused of DUI With a Child in the Car?

 Posted on October 11, 2026 in DUI/DWI/BUI

A DUI charge becomes more serious when a child under 18 is in the vehicle. Tennessee law adds extra jail time and a separate fine, and the penalties increase further if the child suffers serious bodily injury or loses their life. If you are accused of DUI with a child passenger in 2026, an Anderson County, TN criminal defense lawyer can explain the charges and possible defenses.

How Much Jail Time Does a Tennessee DUI With a Child Carry?

Tennessee builds the enhancement directly into its DUI penalty statute. Under Tenn. Code Ann. § 55-10-402, a person convicted of DUI who was accompanied by a passenger under 18 adds at least 30 days in jail. That 30 days is served in addition to any incarceration imposed for the DUI itself. A first DUI already carries a mandatory 48 hours, so the two stack rather than overlap.

A separate $1,000 fine applies under Tenn. Code Ann. § 55-10-403, on top of the fine for the underlying offense. Since the 30-day jail term is mandatory, a judge cannot suspend that time, replace it with probation, or reduce it based on your record or circumstances. Avoiding it requires beating the DUI charge or resolving the case without a conviction on that count.

When Does a DUI With a Child Become a Felony in Tennessee?

The charge escalates sharply if the child is injured. When a child under 18 in the vehicle suffers serious bodily injury as a result of the DUI, the offense becomes a Class D felony and is punished as vehicular assault. If the child loses their life because of the DUI, the offense becomes a Class B felony and carries the penalties for causing a death while driving under the influence. That carries a sentencing range measured in years rather than days.

Serious bodily injury is defined by Tennessee law. It can include:

• An injury that creates a substantial risk of death

• Being unconscious for a long time

• Extreme physical pain

• An obvious or long-lasting change to the person’s appearance, such as scarring

• Long-term loss of function or a serious decline in how a body part, organ, or the mind works

• A broken bone suffered by a child age 12 or younger

Whether an injury meets this standard can be disputed because it can determine whether the offense is charged as a misdemeanor or felony.

Can DCS Open a Case After a DUI Arrest With a Child in the Car?

A DUI arrest with a child passenger often generates a referral to the Department of Children's Services. That investigation operates separately from the criminal case. DCS can open an investigation, interview your children, speak with teachers and relatives, and recommend services. In some situations, it petitions a juvenile court, which can affect custody and visitation.

A DCS finding can be entered even when the criminal case is still pending or eventually dismissed. DCS records are confidential, but information you share with a caseworker can still reach law enforcement and be used in your criminal case.

What Defenses Apply to a DUI With a Child Passenger in Tennessee?

Because the child-passenger enhancement depends on a valid DUI conviction, many defenses focus first on challenging the DUI charge itself. Possible defenses include:

• Challenging whether police had reasonable suspicion to stop the vehicle

• Challenging whether the officer had probable cause to make the arrest

• Questioning how field sobriety tests were given or scored

• Challenging how breath or blood evidence was collected, handled, or tested

• Using video evidence that conflicts with the officer’s report

• Disputing whether a child under 18 was actually in the vehicle

• Challenging whether the DUI caused the child’s injury in a felony case

Felony cases may also depend heavily on medical records and accident reconstruction evidence.
