There's a new parts manager for C & A Transport: Ben Handley. Mike and Jerry wind up taking Ben along on a run; Ben doesn't seem to know much about trucks or mechanics, and he seems to have an alcohol problem. But when they come across a bad traffic accident on the road, Ben Handley gives first aid to the injured motorist-- long ago, Handley had been a doctor. Later, Mike gets Handley a job as a C & A company doctor.
[goof: it would help make the show more authentic if the doc knew how to pronounce the word ""defibrillator"" correctly.]
