Are you obliged to stop and inform the emergency services in this situation?

Why?

The person lying at the right-hand edge of the road may need urgent help. Stop safely, assess their condition, call 112 and provide assistance according to your abilities and the emergency operator's instructions. The duty to help also applies to a witness who did not cause the incident.
