EMS & Emergency Medical Services
NFPA 1917, Standard for Automotive Ambulances (2019 edition) was, for years, the standalone design/performance/testing standard for new automotive ambulances — covering the patient compartment, chassis, low- and line-voltage electrical systems, and crash-test requirements. As of January 1, 2024, NFPA consolidated 1917 — together with NFPA 1901 (fire apparatus), NFPA 1906 (wildland apparatus), and NFPA 414 (aircraft rescue/firefighting vehicles) — into one new standard: NFPA 1900, Standard for Aircraft Rescue and Firefighting Vehicles, Automotive Fire Apparatus, Wildland Fire Apparatus, and Automotive Ambulances.
An ambulance contracted on or after January 1, 2024 is built to NFPA 1900. An ambulance contracted before that date, and still in service, was built to the legacy NFPA 1917 (2019) — that's simply which standard was current at the time, not an error to correct. When specifying a new ambulance purchase or writing a grant narrative, cite NFPA 1900, not the superseded 1917, unless you're specifically describing an existing, already-in-service unit.
NFPA 1900/1917 governs the *vehicle* — chassis, patient compartment construction, electrical systems, crash performance. It has nothing to do with clinical scope of practice, medication protocols, or EMS certification levels, which are governed separately (see *EMS Certification Levels: EMR, EMT, AEMT, and Paramedic*).
A combination or volunteer department that runs its own ambulance(s) is held to the exact same design standard as a large urban EMS system when purchasing new — the standard doesn't scale down by call volume or department size, only the purchasing process and financing path typically differ.
