Is It Illegal to Leave a Pet in a Hot Car in Maine? Laws, Penalties, and What to Do
April 29, 2026

Maine summers can be deceptively warm. Even on a mild day when the outside temperature sits around 70°F, the interior of a parked car can climb to 90°F or higher within minutes — and on an 85°F day, that same interior can hit triple digits in under ten minutes.
If you have ever wondered whether leaving pets in hot cars in Maine is actually against the law, the answer is yes — and the consequences go further than many pet owners realize. Maine addresses this issue through its criminal cruelty statutes, giving specific authorities the power to intervene and holding owners accountable for putting animals at risk.
Is It Illegal to Leave a Pet in a Hot Car in Maine
Yes, it is illegal to leave a pet in a hot car in Maine. Under Maine Revised Statutes Title 17, Section 1031, paragraph K, it is a criminal offense to confine an animal in a building, enclosure, car, boat, vehicle, or vessel of any kind when extreme heat or extreme cold will be harmful to its health — and a violation of this paragraph is a Class D crime.
As of 2025, 32 states and the District of Columbia have laws that address leaving an animal unattended in a confined vehicle under dangerous conditions, such as intense weather conditions. Maine is among them, and its statute is rooted in the state’s broader animal cruelty framework rather than a standalone hot-car law.
Key Insight: Maine’s hot car prohibition applies to both extreme heat and extreme cold, meaning the law is relevant year-round — not just during summer months.
Maine provides for both criminal and civil prosecution paths. A person may be arrested or detained for the crime of cruelty to animals, while no person may be arrested or detained for the civil violation. The attorney for the State may elect to charge a defendant with either the criminal offense under Title 17 or the civil violation of cruelty to animals under Title 7, Section 4011.
This dual-track system gives prosecutors flexibility in how they handle cases, depending on the severity of the situation and the animal’s condition when discovered.

Which Animals Are Covered Under Maine’s Hot Car Laws
Maine’s hot car statute does not limit its protection to dogs and cats alone. Maine Friends of Animals confirmed that the state’s law covers animals broadly, including dogs, cats, horses, and others that may be in danger in a hot or cold vehicle.
The broader cruelty statute under Title 17, Section 1031 applies to “animals” generally, which under Maine law encompasses a wide range of species. Maine law defines “vertebrate” as a subphylum of chordate animals comprising those having a brain enclosed in a skull or cranium and a segmented spinal column, including mammals, birds, reptiles, amphibians, and fish. This broad definition means the protections are not restricted to traditional companion animals.
Important Note: While the statute broadly covers animals, practical enforcement most commonly involves dogs, cats, and horses. If you travel with a less common pet such as a rabbit, bird, or reptile, the law’s protections may still apply, but consult a qualified attorney for guidance on your specific situation.
Maine law also separately defines “small animal” as a bird, reptile, or amphibian or a small mammal other than a cat or dog, commonly kept as a household pet and that is an unrestricted species designated by the Commissioner of Inland Fisheries and Wildlife. This category of animals falls within Maine’s general animal welfare framework, reinforcing that the state’s protections extend well beyond just dogs and cats.

What Conditions Trigger a Violation in Maine
Maine law does not require that an animal already be visibly suffering before a violation occurs. The standard is forward-looking: the conditions must be such that extreme heat or extreme cold will be harmful to the animal’s health. This means an officer does not have to wait for signs of heatstroke to intervene.
Even on a relatively cool day at just 70°F, the internal temperature of a vehicle can reach 90°F. An 85°F day can push the interior to triple digits in just 10 minutes, and after 30 minutes, temperatures can reach 120°F. These temperature dynamics are why Maine’s law focuses on conditions that will cause harm, not just conditions that already have.
| Outside Temperature | Car Interior After 10 Min | Car Interior After 30 Min |
|---|---|---|
| 70°F | ~89°F | ~104°F |
| 80°F | ~99°F | ~114°F |
| 85°F | ~104°F | ~119°F |
| 90°F | ~109°F | ~124°F |
At 105–106°F, a pet is at risk for developing heat exhaustion. If the body temperature rises to 107°F, the animal has entered the critical zone of heat stroke. These thresholds underscore why rapid temperature escalation inside a vehicle is so dangerous.
Other factors that may contribute to a violation include a lack of ventilation, no access to water, and direct sun exposure. A cracked window is generally not considered sufficient protection. Most laws provide that the animal must be confined or unattended in a parked or stationary vehicle, and for a person to violate the law, the conditions in the motor vehicle must endanger the animal’s life. Some statutes specifically state that extreme hot or cold temperatures, lack of adequate ventilation, or failing to provide proper food or drink meet this definition.
Common Mistake: Parking in the shade or leaving a window cracked does not make a hot car safe for your pet. Interior temperatures can still reach dangerous levels within minutes, and neither measure reliably prevents a violation under Maine law.
Who Can Legally Rescue a Pet From a Hot Car in Maine
Maine takes a more restricted approach to who may legally break into a vehicle to rescue a distressed animal compared to some other states. Unlike the roughly 14 states that grant civil immunity to any person who rescues an animal from a hot car, Maine limits authorized rescue to specific categories of officials.
In 2011, Maine Friends of Animals submitted and passed improvements to the existing law, expanding the type of authorities that can help an animal in danger in a hot or cold vehicle. Originally, Maine law only allowed law enforcement officers (police and animal control officers) to intervene, but today first responders (firefighters, EMS) and security guards are also allowed to remove an animal in distress from an unattended vehicle without repercussion, as long as the law is followed.
The notice requirement is an important part of this process. A law enforcement officer, humane agent, or animal control officer who removes an animal must leave written notice in a secure and conspicuous location on or within the motor vehicle, bearing the officer’s or agent’s name and office and the address of the location where the animal may be claimed. A firefighter, first responder, or security guard who removes an animal must similarly leave written notice bearing the person’s name and the address of the location where the animal may be claimed.
An authorized person who removes an animal from a motor vehicle is immune from criminal or civil liability that might otherwise result from the removal. This immunity protection applies only to those authorized categories — it does not extend to private citizens acting on their own.
A well-intentioned civilian in Maine is bound by law not to break into a vehicle, so police should be contacted on a non-emergency line in these situations. Officers will then either send someone for assistance or provide further direction.

Steps to Take When You See a Pet in a Hot Car in Maine
Knowing the right steps to take when you spot a pet in a hot car can make the difference between a safe outcome and a tragedy. Because Maine does not grant private citizens the legal right to forcibly enter a vehicle, your first priority is to act quickly through the proper channels.
- Document the vehicle. Note the make, model, color, and license plate number of the car. This information will be critical when you contact authorities or nearby businesses.
- Alert nearby businesses. If there are businesses nearby, notify their managers or security guards and ask them to make an announcement to find the car’s owner. Many people are unaware of the danger of leaving pets in hot cars and will quickly return to their vehicle once alerted.
- Call law enforcement or animal control. If the owner cannot be found, call the non-emergency number of the local police or animal control and wait by the car for them to arrive. In Maine, these are the authorized parties who can legally remove the animal.
- Stay with the animal. Remain near the vehicle so you can monitor the animal’s condition and provide information to responding officers when they arrive.
- Call 911 if the animal is in immediate distress. If the pet appears to be in acute danger — unresponsive, convulsing, or showing signs of severe heat stroke — call 911 rather than the non-emergency line to request a faster response.
Pro Tip: Save the non-emergency numbers for your local police department and animal control in your phone before you need them. In an urgent situation, having those numbers ready saves valuable time.
It is worth noting that even in jurisdictions without specific laws, endangering an animal’s life in this way could be prosecuted under general anti-cruelty statutes. So while your role as a bystander in Maine is to alert authorities rather than intervene directly, the law still provides a meaningful path to accountability for pet owners who put their animals at risk.

Penalties for Leaving a Pet in a Hot Car in Maine
The penalties for leaving a pet in a hot car in Maine can be significant, and they escalate with the severity of the situation and any prior history of animal cruelty violations.
Under Maine’s criminal cruelty statute, confining an animal in a car or other vehicle when extreme heat or extreme cold will be harmful to its health is a Class D crime. A Class D crime in Maine is a misdemeanor-level offense that can carry up to 364 days in jail and fines set by the court.
In addition to any other penalty authorized by law, the court shall impose a fine of not less than $500 for each violation of this section. The court may also order the defendant to pay the costs of the care, housing, and veterinary medical treatment for the animal, including the costs of relocating the animal.
| Offense Level | Classification | Minimum Fine | Additional Consequences |
|---|---|---|---|
| Standard cruelty violation (hot car) | Class D crime | $500 mandatory | Vet and care costs; possible jail time |
| Aggravated cruelty (extreme suffering or death) | Class C crime | $1,000–$10,000 mandatory | Potential imprisonment; animal forfeiture |
If the animal suffers extreme physical pain or dies as a result of being left in a hot car, the charge could be elevated to aggravated cruelty. A violation of the aggravated cruelty subsection is a Class C crime, and the court shall impose a fine of not less than $1,000 and not more than $10,000 for a first or subsequent violation.
Beyond fines and potential imprisonment, the court, as part of the sentence for a violation, may prohibit the defendant from owning, possessing, or having on the defendant’s premises an animal or animals for a period of time, up to and including permanent relinquishment. This means a conviction could result in losing the right to own pets entirely.
Important Note: Maine’s prosecutor has discretion to pursue either criminal charges under Title 17 or civil violations under Title 7. The path chosen depends on factors like the severity of harm, the number of animals involved, and any prior history of animal cruelty.
The owner may claim a removed animal only after payment of all charges that have accrued for the maintenance, care, medical treatment, and impoundment of the animal. These costs can add up quickly, particularly if the animal requires emergency veterinary treatment for heat-related illness.
Understanding Maine’s laws is one part of responsible pet ownership. Whether you keep a dog, a cat, or a low-maintenance pet, every animal in your care depends on you to make safe choices — and leaving them in a parked car on a warm day is a risk that Maine law takes seriously.
