Approximately 74,000 deer-vehicle collisions occur annually in the UK, causing significant welfare harm to deer and representing a growing road safety concern.
Deer-vehicle collisions cause acute traumatic injury that is often severe - broken limbs, internal injuries, and cranial trauma are common. Deer that survive the initial impact are rarely treated: they cannot be safely approached, veterinary response is slow, and humane killing by an untrained person is both difficult and illegal. Injured deer may lie by roadsides for hours before dying or receiving intervention. This welfare vacuum - where injured deer experience prolonged suffering with no practical rescue pathway - is addressed only partially by trained deer management volunteers with firearms licenses who can provide swift humane dispatch. Driver behaviour modification and infrastructure improvements reduce the frequency of these events.
