When you have an opportunity to perform a service and make $100, you would choose to do so over providing the same service for $50. The inclination to maximize payment for a job performed is natural and makes sense. Unfortunately, truck drivers make similar decisions, but at great risk to other drivers on the road. How? By driving more hours than is legally allowed, or by driving past the point where driver fatigue sets in. Most people don’t realize that truck drivers are often paid by the job.
