The Medical Rapid Access Transports or MRATs are part of the regional Mass Casualty Incident transportation plan and provide a capability to access and provide medical attention in off-road situations. As of July 2021, there are four MRATs in active service (Hampton, Chesapeake, York County and Virginia Beach) with two more on order for Newport News and Norfolk. The Hampton Roads MMRS program was able to purchase these off-road ambulances through a grant and there are plans to add four more MRATs for use in Suffolk, Portsmouth, Isle of Wight and James City Counties.
