When a Deer Is Involved in a Road Traffic Incident
This morning, we were called to assist Surrey Police with a deer that had been involved in a road traffic incident.
On arrival, one of our team assessed the deer. Initially, there were no obvious external signs of injury. However, after a period of careful monitoring, it became clear that the deer had suffered head trauma, combined with signs of capture myopathy.
What is capture myopathy?
Capture myopathy is a serious stress-related condition that can occur in deer following extreme fear, stress, exertion, pursuit, restraint or handling.
The body’s intense response to stress can cause significant muscle damage and can affect vital organs. Sadly, in severe cases, capture myopathy can be fatal.
Importantly, the effects aren’t always immediately obvious. An animal may initially appear relatively normal but deteriorate as the effects of trauma and extreme stress develop. This is why careful assessment and monitoring by appropriately trained people is so important.
What should you do if you see a deer on the road?
If you see a deer, slow down and be prepared for it to move suddenly. Where there is one deer, there may be others nearby.
If a collision is unavoidable, don’t put yourself or other road users at greater risk by making a sudden or dangerous manoeuvre.
If you see an injured deer following a road traffic incident:
Do not approach or attempt to handle the deer.
Keep yourself and other road users safe.
Take note of the exact location and direction of travel.
📞 If the situation presents an immediate danger, the road is obstructed, or there is a risk to people, call 999 and ask for the police.
Even if a deer doesn’t appear badly injured, it can be suffering from internal injuries, head trauma or the effects of severe stress.
Never assume that because a deer can stand or move away, it is uninjured.
Deer are incredibly good at masking pain and distress, and injuries may not be immediately visible. After a road traffic incident, give the situation to trained professionals rather than trying to catch, move or treat the animal yourself.
At Animal Ambulance & Rescue, we are here to assist with these challenging situations and work alongside the police when requested, putting animal welfare and public safety first.
See a deer → slow down.
Hit a deer → keep yourself safe.
Immediate danger → call 999.
Never attempt to handle an injured deer yourself.
