Wild Animal Welfare: Deer and Vehicle Collisions

Deer-vehicle collisions kill thousands of deer and injure hundreds of people annually in the UK, causing traumatic suffering and representing a significant wildlife welfare issue.

Key Facts

An estimated 40,000-75,000 deer are killed in road traffic accidents in the UK each year
Collisions peak in May-June (dispersal of young deer) and October-November (rutting season)
Deer warning signs and reduced speed limits in high-risk areas reduce collision rates
Injured deer that escape after collision often die slowly from internal injuries
The Deer Initiative and local deer management groups advise on collision hotspot mapping

Welfare Considerations

Deer-vehicle collisions cause traumatic injury and death to many thousands of animals annually. Injured deer that are not immediately killed suffer from impact trauma, stress, internal injuries and dehydration before dying. Reducing collision rates through infrastructure measures, driver education and deer management in high-risk corridors is the most effective welfare intervention. Rapid, humane dispatch of road-injured deer by trained individuals is essential where possible.

What You Can Do

Report deer-vehicle collision hotspots to your local deer management group
Reduce speed in areas with deer warning signs, particularly at dawn and dusk in autumn
Contact the British Deer Society if you find an injured deer that requires humane dispatch
Support investment in deer warning signs and wildlife crossings on high-collision roads
