If the Serpentine Belt Breaks, What Exactly Happens?

Took my DP in for its annual service visit and had to have my Cummins serpentine belt replaced because it was cracked.

Which got me to wondering . . . what exactly would happen if the belt broke while on the road?

    Several things. Most likely the water pump will not pump, making the engine overheat. Also the alternator will not charge the batteries. The A/C will not function.

    Might carry a spare.
