What kinds of driving jobs will be most stable as gas prices rise?

Question

I got the book to study for the CDL and I see that there are different kinds of vehicles to test for. What kinds of vehicles will employ the most work stability for a driver as gas prices go up?

Answer 1

Public transportation is the magic word. As gas prices rise, people, especially commuters, look to subways and city buses. Rather than drive

their own cars. Bus driving positions, for local and long distance carriers, unlike trucking are expected to increase as fuel prices drop.

Answer 2

Operating heavy machinery in an oil refinery.
