These ambulances may look like coffins, but they are offering a lifeline to many patients in India.
Patients in tribal areas of Andhra Pradesh can call 108 and summon a bike ambulance immediately.
These areas are remote, have poor roads and cannot be easily accessed by regular ambulances.
The motorcycle-ambulances come with a stretcher and a safety guard. They are also equipped with first aid kits.
These unusual ambulances provide emergency care, shifting patients to nearby hospitals.
The residents in remote areas say the motorcycle-ambulance services are much faster than regular ambulance services.
With the service getting a good response, the state government plans to increase the number of bike ambulances from the present 122.
