Ambulance Type 3 AD is defined as?

• A. Type 3 with decreased GVWR, storage, and payload (12,000 lb or less)
• B. Cutaway van with standard box
• C. Type 3 with increased GVWR, storage, and payload (14,001 lb or more)
• D. Conventional Type 3 without changes

Answer: (C)

Ambulance Type 3 AD refers to a Type 3 ambulance built with a higher weight capacity and more storage/payload. The defining feature is a gross vehicle weight rating of 14,001 pounds or more, which signals a heavier-duty chassis and more equipment space than standard Type 3 units. This makes it distinct from a standard Type 3 or a cutaway van with a box, which don’t specify that increased GVWR. So the AD designation identifies the heavier, more capable configuration designed to carry more gear and potentially treat more patients.
