Every Driver Faces Animal Strikes as 54% of DfT Injury Collisions Happen in Darkness

• Government data analysed by Volvo shows 54% of animal-related injury collisions happen in darkness, against 28% of all injury accidents.
• Between 2021 and 2025, 1,939 people were injured or killed in more than 1,500 animal-related crashes, and 79% happened on country roads.
• The law makes you report a strike on a dog, horse or farm animal to police within 24 hours, but deer and cats are not on the legal list.

Darker Evenings Put Animals and Drivers on a Collision Course on Country Roads

The clocks went back on Sunday, and the drive home from work now starts in the dark. On an unlit country road, a deer, a dog or a loose horse can step into your headlights with almost no warning. New figures show how often that ends in injury.

Volvo has analysed the latest five years of Department for Transport (DfT) data on animal-related road collisions. The headline finding is stark: 54% of animal-related injury collisions happened in the dark. Across all injury accidents, only 28% happen after dark. Put another way, animals turn darkness into a far bigger risk than it is for ordinary crashes, close to double the share.

What the Five-Year Figures Show

From 2021 to 2025, 1,939 people were injured or killed in more than 1,500 animal-related accidents. That works out at about 390 casualties a year. Of those collisions, 28% were fatal or serious, so more than one in four left a driver, passenger or rider with a life-changing injury or worse.

Place is the biggest factor. 79% of animal-related collisions happened on country roads, the lanes and A-roads where there is no street lighting, no pavement and often no fence between the tarmac and the field. If you live in a village, drive to a rural workplace or take a regular route past farmland or woodland, you are in the group these figures describe.

The totals cover only incidents recorded by the police. Volvo says the true number of animal strikes on the nation’s roads is likely to be substantially higher, as plenty of collisions end with a dented bumper and a shaken driver rather than a police report. The British Deer Society estimates that more than 40,000 deer are injured or killed in collisions with vehicles every year.

One caution on the numbers. The 54% and 28% figures compare the share of each type of collision that happens in the dark. They do not show that an individual trip after dark carries a set multiple of daytime risk. The comparison still makes the central point: animal collisions cluster in darkness far more than other injury crashes do.

Why Dark Country Roads Catch Drivers Out

Volvo UK managing director Nicole Melillo Shaw says greater awareness of road risks as the nights draw in can make trips safer, that animals can appear with little warning, and that the incidents are concentrated in darkness and on rural roads. She says staying alert and adapting your speed remain essential on darker winter drives.

The mechanics explain why. Dipped headlights on an unlit road light only a short stretch ahead. Travel at 60mph and you cover 88 feet every second, so an animal that appears at the edge of your beam leaves you very little time to react.

Clocks going back moves the evening commute into the dark for millions of drivers, and Volvo’s analysis shows that darkness is where animal collisions cluster. A road you drive every week in daylight becomes a different proposition after five o’clock.

Newer cars are starting to help. Volvo says its Large Animal Detection technology works with the car’s sensors and automatic braking system, in the same way pedestrian and cyclist detection does. The company is clear that the technology backs up a driver rather than replacing one, and that staying alert remains essential.

What the Law Says If You Hit an Animal

Section 170 of the Road Traffic Act 1988 sets the rules after an accident. If your vehicle hits an animal and you do not give your name and address to someone with reasonable grounds to ask for them, you must report the accident to police. The report has to be made at a police station or to a constable “as soon as is reasonably practicable and, in any case, within twenty-four hours”.

The catch is the definition. The Act says “animal” means horse, cattle, ass, mule, sheep, pig, goat or dog. Cats are not on that list, and neither are deer. So the statutory duty applies if you hit a dog or a loose pony, and the Act does not spell out the same duty for a deer or a cat.

That does not mean you should drive off. A dog with a collar belongs to someone, a horse in the road can cause a second crash, and a deer lying injured in a lane is a hazard to the next driver. The legal list tells you when a report is compulsory; it does not tell you when reporting is sensible. Check your own insurance policy too, as your insurer will want to know about damage to your car whatever the animal.

What the Highway Code Tells You to Do

The Highway Code addresses animals in Rule 214. It tells drivers: “When passing animals, drive slowly. Give them plenty of room and be ready to stop.” It also says: “Watch out for animals on unfenced roads.” Do not scare them by sounding your horn, revving your engine or accelerating hard once you have passed. If a herd blocks the road, stop and switch off your engine until the animals have left.

Rule 215 covers horses. When you see a horse on a road, you should slow to a maximum of 10mph. It reminds drivers that horses are flight animals and can move incredibly quickly if startled, and that feral or semi feral ponies need the same consideration as ridden horses.

Rule 214 goes further than slowing for animals you can see. It tells drivers to look out for animals being led, driven or ridden on the road and to take extra care. Rule 213 adds that on narrow sections of road, horse riders can ride in the centre of the lane, and drivers should let them do so for their own safety, so they can see and be seen. In practice that means waiting behind a rider on a narrow lane until it is safe to pass, rather than edging past.

Practical Ways to Cut Your Risk on Winter Evenings

You cannot remove the risk, but you can shrink it. Volvo’s advice is to stay alert and adapt your speed, and the figures say that counts most on rural roads after dark.

• Slow down on unlit country roads, even where the limit is 60mph. The limit is a ceiling, not a target.
• Watch the verges and gateways, and treat any deer warning sign as a real instruction to slow.
• Follow Rule 214 when you see animals ahead: drive slowly, give them room and be ready to stop.
• Keep your windscreen and headlights clean, and get the aim of your headlights checked at your next service.
• Know your route. A lane that is quiet in daylight sits among the country roads where 79% of animal collisions happen.

After a strike, stop somewhere safe if you can, switch on your hazard lights and check for injuries to anyone in the car. Photograph the scene and any damage before you move the vehicle, and note the road name and time. If the animal is a dog or a horse, give your details to the owner or report the accident to the police within 24 hours, as the Act requires.

The darkest months are only starting, and the 54% figure shows when the danger is highest and where. Slow down on the lanes, keep your eyes on the verges, and treat every dark country road as one where something could step out.
