With the robust ambulance network missing across the country, the central government has come up with the National Ambulance Code with necessary amendments in the Central Motor Vehicles Rules (CMVR), 1989, which defines the constructional and functional requirements for road ambulances.

In this, four variants of ambulances have been approved: Type A Road Ambulance: Medical First Responder; Type B Road Ambulance: Patient Transport Vehicles; Type C Road Ambulance: Basic Life Support Ambulance and Type D Road Ambulance: Advanced Life Support Ambulance.
