Promotions – Look around - a majority of senior engineering positions are occupied by PEs. An increasing number of companies are requiring registration for advancement.
Consulting – Only PEs can consult in private practice and serve as expert witnesses in court.
Respect – PEs gain the respect of peers within the engineering community. Registered engineers also enhance their employers reputation.
Professionalism – Registration by a majority of engineers is essential if you are to enjoy the benefits of established professions such as medicine and law.
It's the Law – This is probably the most important reason. Tennessee State law reserves use of the word "engineer" for licensed professional engineers
