27. Crossing animals
An animals-crossing warning indicates a place or road section where wild animals, livestock or ridden animals may enter or cross the road. Animals may appear suddenly, move unpredictably or be difficult to see in darkness, vegetation or poor weather.
Drivers should reduce speed, scan both sides of the road and remain prepared to stop. The warning sign does not itself give animals priority or impose a numerical speed limit, but drivers must avoid frightening, endangering or colliding with them.

What does an animals-crossing sign mean?
It warns that animals may enter or cross the road in the area ahead.
Which animals may the sign refer to?
Depending on the symbol and local conditions, it may refer to deer, cattle, horses, sheep, goats, wild boar or other animals.
How can you recognise an animals-crossing sign?
It is commonly a triangular warning sign displaying the silhouette of an animal. The species shown may indicate the type of animal most likely to be encountered.
Does the sign mean animals are always present?
No. It indicates an increased likelihood of animals crossing, not that animals will be present every time.
Does the sign impose a speed limit?
No. The normal posted or general speed limit remains applicable, but drivers must reduce speed when necessary to react safely.
Do animals have priority because of the sign?
No automatic priority is created by the warning sign. Drivers must nevertheless avoid danger and allow animals already on the road to pass safely.
How should you approach an animal-crossing area?
Reduce speed, increase your following distance and scan the road, verges, fields and vegetation for movement or reflected eyes.
When are wild animals most likely to appear?
Animal activity is often greater around dawn, dusk and darkness, although animals may cross at any time.
Why should you expect more than one animal?
Many animals travel in groups. When one animal crosses, others may follow immediately from the same direction.
Should you sound the horn?
Avoid unnecessary horn use or engine revving because it may frighten an animal and make its movement less predictable. Use a warning only when reasonably necessary to prevent danger.
Should you use full-beam headlights?
Use the appropriate lights without dazzling other road users. When an animal is visible, reduce speed and avoid relying on full beam to make it move away.
What should you do when an animal is on the road?
Slow down smoothly, stop when necessary and allow it enough time and space to leave. Avoid sudden acceleration or aggressive steering.
Should you swerve to avoid an animal?
Avoid an uncontrolled swerve that could cause a collision with another vehicle, tree, barrier, cyclist or pedestrian. Brake firmly while maintaining control and steer only when a safe escape path is clearly available.
How should you pass livestock?
Pass only when the animals and their handlers have sufficient space. Drive slowly, avoid noise and be prepared for an animal to change direction unexpectedly.
How should you pass a horse and rider?
Reduce speed, leave a large lateral distance and pass quietly. Avoid sounding the horn, accelerating sharply or passing when oncoming traffic prevents sufficient clearance.
Must you follow instructions from an animal handler?
Follow lawful instructions from an authorised person and cooperate with handlers controlling animals on or across the road.
May you overtake near an animal crossing?
The warning sign does not necessarily prohibit overtaking, but overtaking should be avoided when animals, limited visibility or approaching traffic make the manoeuvre unsafe.
What if an animal appears behind another vehicle?
Maintain enough following distance to see beyond the vehicle ahead. Be prepared for it to brake suddenly when an animal enters the road.
What should motorcyclists and cyclists do?
Reduce speed, keep both hands firmly in control and avoid sudden movements. Animals may react unexpectedly to quiet or fast-approaching two-wheeled vehicles.
What should you do after hitting an animal?
Stop safely, activate the hazard warning lights and check for injured people. Contact the emergency services or police when necessary and do not approach a wounded wild animal, which may defend itself.
Should you move an injured or dead wild animal?
Normally not. Keep a safe distance and allow the police, wildlife authorities or an animal-rescue service to handle it.
Can animals be present without a warning sign?
Yes. Drivers remain responsible for observing the road and adjusting their speed even where no animal warning sign is displayed.
