Dogs and cats should travel in the back seat using a properly secured carrier, crate, or vehicle safety harness designed for pets. Do not allow a pet to ride loose, sit on the driver’s lap, travel in the front seat, or put its head outside the window.
Safe pet travel protects the animal, the driver, and everyone else inside the vehicle. An unrestrained pet can distract the driver, move into the footwell, interfere with vehicle controls, or be injured during a sudden stop.
Prepare before leaving, select an appropriate restraint, bring identification and supplies, and plan regular breaks during longer trips.
How should dogs and cats ride in a car?
Pets should ride securely restrained in the back seat or in a properly designed cargo-area restraint system.
Small dogs and cats can travel in a secured carrier. Larger dogs may use a vehicle safety harness or an appropriately secured travel crate.
The restraint should prevent the pet from roaming through the vehicle, entering the driver’s space, falling into the footwell, or being thrown during a sudden stop.
The Centers for Disease Control and Prevention recommends keeping seat-riding pets in the back seat using a harness attached to the seat buckle. Crates should be secured so they cannot slide or shift. [1]
What is the safest restraint for a pet in the car?
The right restraint depends on the pet’s size, the vehicle, and whether the product has been independently evaluated for vehicle travel.
| Restraint | Best suited for | Safety considerations |
|---|---|---|
| Secured pet carrier | Cats and small dogs | The carrier should be properly sized, ventilated, closed, and attached according to the manufacturer’s instructions. |
| Vehicle safety harness | Medium and large dogs | Use a harness designed specifically for vehicle restraint rather than a collar or standard walking harness. |
| Secured travel crate | Dogs that are comfortable in crates | The crate must be properly anchored and large enough for the pet to stand, sit, lie down, and turn around. |
| Cargo-area crate | Larger dogs in suitable SUVs or vans | Use a properly rated crate and anchoring system. Confirm that the vehicle’s cargo connection points can support the system. |
Do not attach a vehicle restraint directly to a pet’s collar. A collar can place dangerous pressure on the neck during sudden movement.
Do not assume that every product advertised as “crash tested” passed an independent test. Look for clear test evidence or independent certification.
The Center for Pet Safety independently certifies qualifying harnesses, carriers, and crates. It also warns that manufacturer claims of crash testing do not automatically mean a product passed testing. [2]
Can a dog or cat sit on the driver’s lap?
No. A pet should not sit on the driver’s lap while the vehicle is moving.
A pet on the driver’s lap can block the steering wheel, interfere with pedals or vehicle controls, restrict movement, and pull the driver’s attention away from the road.
Even a normally calm pet may react suddenly to another animal, a loud sound, traffic, or an open window.
The National Highway Traffic Safety Administration defines distracted driving as any activity that takes attention away from safe driving. Keeping pets secured prevents them from becoming an avoidable distraction. [3]
Can a pet ride in the front seat?
The back seat is the recommended location for dogs and cats traveling in passenger vehicles.
The front seat places the pet close to the driver and front airbag. It also makes it easier for the pet to interfere with steering, controls, and the driver’s view.
Secure the pet in the back seat using an appropriate carrier or vehicle safety harness.
Should dogs ride with their heads outside the window?
No. Dogs should remain fully inside the vehicle while it is moving.
Airborne dirt, stones, insects, branches, and road debris can injure a dog’s eyes, ears, nose, or face. A dog may also attempt to climb or jump through an open window.
Keep windows high enough to prevent the pet from putting its head or body outside. Use the child-window lock if your vehicle has one.
Both the CDC and ASPCA advise against allowing pets to ride with their heads outside the window. [1] [4]
How do you prepare a pet for car travel?
Begin with short, positive car trips and gradually increase the travel time.
-
Introduce the restraint at home
Allow your pet to inspect the carrier, crate, or harness before the first drive. Use praise and small rewards to create a positive association.
-
Practice inside a parked car
Secure your pet while the vehicle is parked and turned off. Keep the first session brief.
-
Take a short drive
Begin with a drive lasting only a few minutes. End the trip somewhere calm or familiar.
-
Increase travel time gradually
Add a few minutes to later trips as your pet becomes more comfortable.
-
Watch for travel stress
Heavy panting, repeated vocalizing, drooling, vomiting, trembling, or attempts to escape may indicate stress or motion sickness.
-
Ask your veterinarian for help
Discuss frequent motion sickness, severe anxiety, medical conditions, or medication needs before a long trip.
The CDC and ASPCA recommend preparing pets with a series of short drives before attempting a longer road trip. [1] [4]
What should you pack when traveling with a pet?
A pet travel kit should include water, food, medication, identification, waste supplies, veterinary records, and familiar comfort items.
- Fresh water
- Pet food and treats
- Food and water bowls
- Leash and secure collar or harness
- Waste bags or litter supplies
- Prescribed medications
- Pet first-aid supplies
- Vaccination and medical records
- Cleaning supplies and towels
- A familiar blanket, bed, or toy
- A current photograph of your pet
- Contact details for your veterinarian
- Contact information for an emergency veterinarian near your destination
Keep essential supplies where they can be reached without unpacking the entire vehicle.
When should you feed a pet before a car trip?
Feed your pet a light meal approximately three to four hours before leaving rather than feeding inside the moving vehicle.
Bring plenty of water and offer it during safe stops. Long trips should include regular opportunities for dogs to stretch, use the bathroom, and drink.
Keep dogs leashed before opening the vehicle door. Cats should remain inside a closed carrier unless they are in a secure indoor location.
CDC travel guidance recommends feeding three to four hours before departure and making frequent stops during longer drives. [1]
What identification does a traveling pet need?
Pets should have a registered microchip and a secure collar with current contact information.
Confirm that the microchip company has your current phone number and address. Add a temporary travel tag containing your mobile number and destination information when appropriate.
Carry a recent photograph of your pet and copies of relevant vaccination and medical records.
Travel documentation requirements may differ by state, country, airline, and transportation provider. Check the rules before leaving and ask your veterinarian whether a health certificate is required.
The CDC recommends microchipping pets, updating contact information, keeping vaccinations current, and checking destination requirements before travel. [1]
Can you leave a pet alone in a parked car?
No. Never leave a dog or cat unattended inside a parked vehicle.
Vehicle temperatures can become dangerous quickly, even when the outside temperature feels mild or the windows are partly open.
Cold weather also creates a risk because a parked vehicle may hold dangerously low temperatures.
Plan stops so that a responsible adult can remain with the pet or choose pet-friendly locations where the animal can accompany you safely.
The CDC and ASPCA advise never leaving an animal alone in a parked vehicle because both heat and cold can become life-threatening. [1] [4]

Frequently asked questions about pet car safety
What is the safest way for a dog to ride in a car?
A dog should ride in the back seat using a properly fitted vehicle safety harness or inside a secured travel crate. Use a product designed for vehicle travel and follow the manufacturer’s installation instructions.
What is the safest way for a cat to ride in a car?
A cat should remain inside a closed, ventilated carrier secured in the back seat. Do not allow a cat to roam freely inside the vehicle.
Can a dog ride in the front passenger seat?
The back seat is the recommended location. The front seat places the dog close to the driver and front airbag and increases the risk of distraction.
Can a dog ride with its head outside the window?
No. Road debris, insects, branches, and other objects may injure the dog’s eyes, ears, nose, or face. A dog may also attempt to climb or jump through an open window.
Should a dog’s car restraint attach to its collar?
No. Vehicle restraint systems should not attach directly to a collar. Use a properly fitted safety harness designed for vehicle use or an appropriate carrier or crate.
How often should dogs stop during a road trip?
Dogs should receive regular opportunities to drink, stretch, and use the bathroom. The exact timing depends on the dog’s age, health, and normal routine. Puppies, senior dogs, and pets with medical conditions may need more frequent stops.
Can you leave a pet in the car with the windows open?
No. Partly opened windows do not prevent the vehicle from reaching dangerous temperatures. Never leave a pet unattended in a parked vehicle.
