Ambulance Type 1AD is best described as which?

• A. Type 1 with a smaller GVWR.
• B. Type 1AD: Type 1 but with increases GVWR, storage, payload.
• C. Type 2 with increased GVWR.
• D. Ambulance Type 3.

Answer: (B)

Ambulance classifications differentiate by base chassis and how much weight and gear they’re designed to carry. A Type I ambulance uses a truck-style chassis with a separate patient compartment. The AD suffix means this is a Type I design but with increased GVWR, plus more storage and payload capacity. In other words, it’s still Type I in layout, but built to carry more equipment and heavier loads than a standard Type I. It isn’t a Type II or Type III, which refer to different chassis designs, and it isn’t a Type I with a smaller GVWR.
