A fair bit, actually. The initial cost is higher due to the 4WD system and any necessary modifications. It’s an investment, really, but one that could save lives.

What are the main maintenance differences between 2WD and 4WD ambulances?

4WD ambulances have more components, which means more potential points of failure. This translates to increased maintenance, including regular checks of the transfer case, differentials, and drive shafts. You’ll need to keep an eye on those fluids!

Are there any legal requirements for ambulances to have 4WD?

Not a blanket requirement, no. However, regulations and standards often recommend 4WD for ambulances operating in challenging terrains or adverse weather conditions. It’s about ensuring patient safety and effective response.
