How to stay safe as the threat of deer-vehicle collisions increases

It's estimated up to 700 human injuries and 20 deaths could occur this year across the UK due to deer-vehicle collisions.

As a result, Highways England, CLA (Country, Land and Business Association) and The Deer Initiative have joined forces to warn motorists about the heightened risk of deer-vehicle collisions this autumn.

The changes to the clocks this weekend means deer movement will coincide with peak commuting hours, increasing the likelihood of motorists seeing and colliding with a deer.

Highways England says: “We urge drivers to be more aware during this time of year and take note of the following advice:

Autumn sees a greater chance of encountering a deer in the road

“When you see deer warning signs or are travelling through a heavily wooded or forested stretch of road, check your speed and stay alert.

“If your headlights are on, use full-beams when you can; but dip them if you see deer, as they may ‘freeze’.

“More deer may follow the first one you see so be alert if you see one at first.

“Be prepared to stop. Try not to suddenly swerve to avoid a deer. Hitting oncoming traffic or another obstacle could be even worse.

“If you have to stop, use your hazard warning lights.”

Around two million deer are currently living wild in the UK.

October through to December is considered a high-risk period as deer will be on the move for the autumn mating season, also known as the rut.

The highest risk of a deer-vehicle collision occurring is said to be between sunset and midnight, and the hours shortly before and after sunrise.

Across the UK it is estimated that there could be up to 74,000 deer-related motor vehicle accidents this year alone, resulting in 400 to 700 human injuries and 20 deaths.

Richard Leonard, Head of Road Safety at Highways England, said: “We want everyone to reach their destination safely and without incident.

“The one time you might experience a close encounter with a deer is when you are behind the wheel, especially during the rutting season when their increased activity could bring them out onto the roads. Our advice to drivers is to stay vigilant, especially during dawn and dusk when the deer are more mobile, which coincides with the morning and evening rush hour. Slowing down will give you more time to brake if an animal darts out into the road without warning.”

Deer warning signs are placed in areas where deer are most active and road crossings are frequent. It might be a route you travel on regularly or a road you know well but wildlife behaviour can be unpredictable. Deer often travel in groups so if you’ve seen one and avoided it, one or two more could follow it.

The CLA represents farmers, landowners and rural businesses across England and Wales.

CLA Regional Surveyor Tim Woodward said: “As the clocks go back, motorists should be alert to the risk of deer running in front of vehicles which can happen with little or no warning.

“A collision with a deer can happen at any time of year but the darker evenings in the autumn increase the risk of the animals unexpectedly crossing roads and running straight into the line of oncoming traffic.

“Not only is this an animal welfare issue, but considerable damage can be done to a vehicle if it collides with an animal as large as a deer, and there is the risk that driver and passengers could be injured, too.

“Remembering how to react when you see deer can reduce the risk of a potentially life threatening accident.”

CLA, Highways England and The Deer Initiative are also offering advice to drivers on what to do if you see an injured deer on the roadside or hit a deer while driving.


Pull over at the next safe place.

Call the Police. They will deal with road safety issues and have access to a specialist who will know the best course of action for the animal if it is alive.


Keep yourself and anyone with you as safe as you can.

Park your car in the safest place with hazard lights on. Consider using it to also warn other road users.

Call an ambulance if human injuries warrant it.

Call the Police.


Not to approach live deer. Doing so may cause them to run across traffic causing another accident. If you attempt to move or handle live deer, you may be injured if they struggle.
