The Latest UK Law on Driving with Dogs in The Car
As a nation of dog-lovers, it should come as no surprise that over 7 million dog owners in the UK travel with their pets in their car at least once a week. Whether it’s going on an adventure, visiting family, or even just attending a routine vet appointment, it’s commonplace to load your dog into your car and off you go.
However, a lot of pet owners don’t know that there are actually laws around how they can travel with their dogs in their car in the UK. If you don’t follow these laws, you can face fines or points on your license.
So if you are a dog owner, here’s what you need to know to travel safely and legally with dogs in your car by UK laws and regulations.
What Does the Law Say About Dogs in Cars in the UK?
In the UK, the law requires dogs to be suitably restrained when travelling in a vehicle. Rule 57 of the Highway Code specifically states that dogs must be secured so they cannot distract the driver or cause injury to themselves or others if the car stops suddenly.
Failure to restrain your dog properly could result in fines, penalty points on your driving licence, and even impact your car insurance coverage. It is considered careless driving if you allow your dog to roam freely or sit on your lap while driving since this distracts you and increases the risk of accidents.
How Must Your Dog Be Restrained in the Car?
Your dog needs to be secured in a way that fits their size and temperament safely. Restraint options that comply with the law include seat belt harnesses, secure dog crates, or dog guards that separate the boot from the rear seats.
Each method prevents your dog from moving about freely in the car, reducing driver distraction and protecting your dog from injury in an accident.

Are Dogs Allowed in the Front Seat?
While there is no specific prohibition against dogs travelling in the front seat, it is strongly discouraged because dogs in the front passenger seat can distract the driver.
Additionally, if your car has a passenger airbag, it poses a significant risk of injury to your dog during an accident. If your dog must be in the front, ensure they are properly restrained with a harness and that the airbag is disabled.
The Risks When Driving Without Restraining Your Dog
An unrestrained dog in your car can pose several risks when driving, and you’re also setting yourself up for financial punishment if you’re caught or if an accident should happen.
The biggest issue with an unrestrained dog in a car is around safety. A lot of drivers don’t think twice about letting their dog move about their car freely, but this can be a serious distraction and greatly increases the chance of an accident that not only endangers you and your dog but also others on the road. An accident that would likely invalidate your car insurance claim as you should not have had an unrestrained dog in your car in the first place.
If you were to suddenly stop or swerve while driving, an unrestrained dog is at risk of injury and can even injure yourself or your other passengers. Just like you shouldn’t allow anyone to travel in your car without their seat belt fastened, you shouldn’t travel with a loose dog that can become a hazard if you need to slam on your brakes.
Aside from the health and safety reasons, if you are caught driving with an unrestrained dog in your car then you can potentially face legal consequences including fines up to £5,000, penalty points, or even court appearances.
Can You Leave Your Dog Alone in the Car?
Leaving your dog unattended in the car poses a serious threat to their health. Temperatures inside vehicles can rise rapidly even on mild days, putting your dog at risk of heatstroke.
While the law does not specifically forbid leaving dogs in cars, neglect resulting in distress or injury can lead to prosecution under the Animal Welfare Act 2006. It is always safest to avoid leaving your dog alone in the car, especially in warm weather.
Tips for Comfortable and Safe Car Travel with Your Dog
Making car journeys comfortable and safe for your dog requires some preparation:
- Use an appropriate restraint that fits your dog correctly.
- Provide soft bedding or a dog mat inside crates to keep them comfortable.
- Ensure adequate ventilation and keep the car cool.
- Take regular breaks on long journeys to allow your dog to stretch and relieve themselves.
- Avoid feeding your dog immediately before travel to reduce motion sickness.
- Keep water available throughout the trip.
- Avoid letting your dog hang their head out of the window due to safety risks from debris and sudden stops.
Keeping Your Car Safe from Dog Damage
Even restrained dogs can inadvertently cause damage to car interiors by scratching, shedding hair, or drooling. Using effective defenders such as washable dog car seat covers, barrier rugs, and car boot liners for dogs can protect your upholstery and preserve your vehicle’s value while keeping your dog comfortable.
Key Legal Obligations and Safety Advice
Rule 57 of the Highway Code is there to keep you, your dog, and other road users safe when travelling with a dog in your car.
Remember, driving with an unrestrained dog risks fines, penalty points, accidents, and insurance issues, so make sure that you own a seat belt harness attachment or other form of dog guard before allowing your dog in your car.
And when getting your car ready for travel with your dog, be sure to keep your vehicle clean and comfortable with dog covers and boot liners like ours from Pet Rebellion.
