When the Commission on Accreditation of Ambulance Services (CAAS) released its Ground Vehicle Standard GVS V1.0 for new ambulances in 2016, they were not finished with their work on creating positive change in EMS vehicles.  In fact, they were just getting started.

“We created and published the initial CAAS Ground Vehicle Standard at the request of numerous industry associations who were seeking an ambulance standard for the broad spectrum of EMS,” states Mark Van Arnam, Administrator of the CAS GVS Standard. “These same stakeholders convinced us that there was a severe need for a standard for remounted ambulances.”

And now as CAAS prepares for release of GVS V2.0 in July 2019, the newly developed GVS Remount Standard that is included as a part of the updated V2.0 document stands out as a major development in enhancing the safety, quality and durability of remounted ambulances as the most rapidly growing segment of the emergency vehicle market.

Project Kickoff

CAAS started their project to develop a new Remount Standard in June 2017 by convening an open Ambulance Remount Forum. That event was attended by over 175 people who had varied interests in remounted ambulances.

Participants included Final Stage Ambulance Manufacturers (FSAMs), independent remounters, EMS Providers, regulators, federal partners and other subject matter experts.

Information and feedback gathered at that meeting provided the groundwork for the Remount Standard development project. (See “Rethinking Remounts,” JEMS, August 2017)

CAAS is an ANSI accredited Standards Developer Organization that defines the “gold standard” for operations in the medical transportation industry. As such, CAAS operates under ANSI procedures for development of its standards.

Mark Postma, Co-Chair of the GVS Committee says, “CAAS developed the Ground Vehicle Standard through a two-year process that complied with ANSI’s Essential Requirements.  We created a Remount Standard Work Group using that same process of committee members balanced by organization type.”

The development of a comprehensive Remount Standard with specific and defined requirements proved to be a substantial task. “The ambulance remount business and process is complex with numerous moving parts,” says Van Arnam.  “In some ways, the development of the Remount Standard was more difficult than the initial GVS V1.0 standard project for new ambulances.”

After thousands of man-hours of meetings and group participation over the course of two years, the GVS Remount Standard is finally complete.  “We had a rapidly growing industry segment producing critical lifesaving emergency vehicles, with basically no standards for the remounters or their products,” said Postma. “We have now set the bar by establishing real standards that must be met with a primary focus on safety.”

New Considerations

A review of the actual standard shows that they have done exactly that. For starters, there are requirements that the actual Remounter must meet in order to comply. It is now clear that federal law considers an ambulance Remounter as a new vehicle manufacturer.

Accordingly, they are required to register with NHTSA as such and meet the same federal requirements as any vehicle manufacturer.  This includes strict compliance with all applicable Federal Motor Vehicle Safety Standards that apply to ambulances and their chassis.

Also, The Remounter must also meet stringent requirements for certification of multistage motor vehicles as required by federal law. This would include providing Final Certification of the actual vehicle as being compliant with all applicable FMVSS and NHTSA standards.

In addition, the Remounter is obligated under the new GVS standard to provide the purchaser with such items as product liability insurance coverage, garage keepers insurance coverage, vehicle warranty and verification of financial resources.

Process and Product

And that’s not all.  There is a complete section on actual production process requirements that a Remounter must meet for every vehicle. This type of thing is very common for the Final Stage Ambulance Manufacturers to have, but it is likely to be new ground for many Remounters.

Process documentation of strict compliance with FMVSS, the Incomplete Vehicle Document (IVD) requirements for the specific chassis utilized as well as the OEM Body Builder’s Guide for that chassis, is all part of the new minimum standard and something that the Remounter must have and should be provided to the purchaser upon request.

The Remounter must have a process for determining the suitability of the existing body module to be remounted and be able to present that information accurately to the owner of the ambulance, as well as performing steps to inform the purchaser of any unseen defects or deficiencies found during the remount procedure.

In addition, a Scope of Work document is required which includes an itemized proposal of the overall project, as well as weight, balance and minimum payload projections for the specific vehicle with the new chassis.

The new standard provides special attention to FMVSS safety standards that are federal requirements and must be considered in the remount process.

Specific requirements for the modular body door locks and latches, as well as seats, belts and anchorages in the patient compartment are also delineated in detail.

Additionally, the GVS Committee has included consideration for some of the new NIOSH/SAE Safety Standards (that are currently required in all new vehicles) for inclusion in remounts as applicable.

Compliance to the new SAE standards for Patient Compartment Seating (SAE J3026) and Equipment Retention (SAE J3043) are both required on a remounted ambulance for any new installation or modification of the corresponding features from that which was provided in the original production vehicle.

Compliance with the new SAE J3027 Litter Integrity, Retention and Patient Restraint requirement is required for all Remounts.  New safety requirements for console retention, backup camera and anti-theft device are also required for all units.

Testing and Documentation

The Ambulance Manufacturer’s Division (AMD) of the National Truck Equipment Association, the trade association of North American ambulance builders, maintains and publishes the AMD Standardized Test Methods that are used by all ambulance manufacturers for performance tests and quality control in production of new ambulances.

While a few of these AMD tests are destructive type testing for prototype vehicles, the majority of them can be utilized for testing a single one-off production vehicle.

The GVS Remount Standard specifically identifies and requires 15 of these AMD Standardized Tests that must be performed on every remount produced under the standard. These tests are quite varied, and cover such items such as sound level, lighting performance, high/low voltage testing and aspirator performance.

While labeling and documentation requirements for new ambulances is well understood, this is an area that has been confusing and historically lacking on some remounts.  GVS now clearly establishes the requirements and expectations for these items in remounted ambulances.

First, the NHTSA federal requirement for the Final Stage Manufacturer (Remounter) to provide a Final Stage certification label is distinctly noted.

GVS made strong advances on vehicle labeling and documentation with their V1.0 requirements for new ambulances. The GVS new Ambulance Certification Sticker as well as both their Vehicle Compliance and Payload Verification documents provide the vehicle purchaser and state inspectors with vital vehicle information.  

The GVS Remount Standard now creates a similar labeling and documentation system for remounts. An Ambulance Remount Compliance sticker and accompanying document templates will now provide that same vital information for remounted ambulances.



While the GVS new vehicle sticker is blue, the Remount compliance sticker and accompanying documents are coded in red and provide critical vehicle information.

Not a Recertification

The GVS Remount Standard explicitly states that that the GVS Ambulance Remount Compliance sticker verifies that the ambulance has been remounted in accordance with the GVS Remount Standard and does not provide or imply certification to a new ambulance standard.  

The US General Services Administration has made it clear that the original “Star of Life” certification sticker is not transferable to a remounted ambulance, and that a valid certification sticker must display the correct VIN number of the chassis currently in use.

A suggestion is made that the purchaser contact their State or local EMS licensing authority to determine the eligibility of their vehicle to be relicensed within their operating area following a remount process.

“The ambulance remount business has grown exponentially over the past 10 years,” stated Van Arnam. “In this era of tight budgets and difficult reimbursement, the economies of remounting an ambulance can make real sense for many purchasers. It is important however, that remounts are done without compromising the safety of the patient or the crew riding in the vehicle.  The CAAS GVS Remount Standard establishes real standards for safety and quality while maintaining the economic advantages of remounting.”
