Yes, leaving children unattended in a vehicle is illegal in many states, though specific age limits and time restrictions vary significantly[1]. California prohibits leaving children under 6 alone without supervision from someone at least 12 years old when conditions pose a risk[2]. Florida makes it illegal to leave children under 6 in a car for more than 15 minutes[3]. Texas restricts leaving children under 7 unattended for more than 5 minutes[4]. Even in states without specific statutes, child endangerment laws typically apply when leaving a child in a vehicle creates risk of harm[1].
The statistics behind these laws are sobering. Since 1998, 1,041 children have died from pediatric vehicular heatstroke in the United States[5]. An average of 37 children die each year after being left in hot vehicles, with 39 deaths recorded in 2024 and 31 already in 2025[5].
Vehicle interiors heat rapidly—even on mild days. A car parked in 70°F weather can reach 104°F within 30 minutes[6]. On a 90°F day, interior temperatures can exceed 130°F within the same timeframe. Children's bodies heat 3-5 times faster than adults, making even brief exposure dangerous.
The circumstances of these deaths reveal important patterns[5]:
Over half of victims (54%) were under 2 years old[5]. These statistics underscore why lawmakers treat leaving children in vehicles as a serious offense regardless of intent.
Laws vary considerably by state. Some specify exact ages and time limits; others rely on broader child endangerment statutes[1].
| State | Age Restriction | Time Limit | Key Provisions |
|---|---|---|---|
| California | Under 6 | Any duration if risk exists | Requires supervisor age 12+ if leaving child[2] |
| Florida | Under 6 | 15 minutes | Stricter if engine running or immediate danger[3] |
| Texas | Under 7 | 5 minutes | Requires companion age 14+ if leaving child[4] |
| Indiana | Under 6 | 30 minutes | Class A misdemeanor[7] |
| Michigan | No specific age | Risk-based | Illegal if circumstances pose unreasonable risk[8] |
| Illinois | Under 6 | 10 minutes | Must not endanger health/safety |
Approximately 20 states have passed legislation specifically addressing children left unattended in vehicles[1]. These laws typically set:
States without dedicated unattended child laws still prosecute cases under general child endangerment, neglect, or abuse statutes[2]. In New Jersey, courts have held that leaving a child alone for even 5-10 minutes can constitute abuse or neglect[9]. The absence of a specific statute does not mean the action is legal—it simply means prosecutors use different legal frameworks.
Consequences range from misdemeanor citations to felony charges depending on circumstances and outcomes[8].
Texas: Class C misdemeanor, fines up to $500[4]
Indiana: Class A misdemeanor, up to $5,000 in fines and one year imprisonment[7]
Michigan penalties escalate based on harm:
Beyond criminal charges, leaving children unattended in vehicles typically triggers Child Protective Services investigations[2]. Even first-time incidents may result in:
If another child or bystander is injured while attempting to rescue your child from a hot car, you may face civil lawsuits[2]. Many states have "Good Samaritan" laws protecting rescuers who break windows to save children, but the vehicle owner may bear liability for damages.

Courts and prosecutors consider multiple factors when determining charges and penalties[2]:
A parent who runs into a gas station for 2 minutes on a 65°F day faces very different consequences than one who leaves a toddler for 30 minutes during summer heat[2].
The safest approach is never leaving children alone in vehicles, regardless of duration or weather[5]. What seems like "just a minute" can extend unexpectedly due to lines, distractions, or emergencies.
