CUM-ISC Lost second belt, stuck along freeway...driveable?

I have a 99 Monaco Dynasty with Cummins ISC-330.
The serpentine belt is FINE, but the second belt that goes up to a pump just flew apart.

I'm stuck along the freeway and am waiting for Good Sam Roadside assistance to figure out a solution. However, the mobile mechanic they were going to dispatch says the belt is not available within a couple hundred miles.

So, if I need to camp out for a bit, I'm wondering if it's driveable for short distances without the second belt.
What does that pump do?

A/c......start it up and verify you have no a/c

The second belt is likely for the air conditioning compressor. The serpentine belt drives the alternator and waterpump. Make certain the damaged belt will not interfere with any other components. Watch your gauges, you should be ok.

Looks like the dash A/c compressor to me
If so it is driveable. Start engine see if A/C gets cold if it does not I am right and you can drive
