Four Alarm Mini-Ambulance

The Four Alarm is the largest production model ambulance we offer, capable of transporting four attendants (including driver) and one patient.  The deck features a swing-down handrail and can be configured to accommodate either a standard spine board or a full-size ambulance cot.  The front seat swivels 180-degrees so that the attendant can tend to the patient’s head if need be.

Built atop the proven Yamaha Drive chassis the Four Alarm is available in both gas and electric power and comes standard with custom paint, lift-kit, and a slew of other features.
