DIESEL MECHANIC
Fixes the trucks that move America. Steady demand, transportable skills, growing complexity with modern emissions systems. Rhode Island is not a right-to-work state — union density is higher than average and prevailing wage rules cover most public projects.
The License.
Most states issue a journeyman license (allows you to work under a licensed contractor) and a separate master or contractor license (allows you to pull permits and run your own business). The journeyman license typically requires completing your apprenticeship and passing a written exam; the master/contractor license requires additional field hours — usually 2 years as a journeyman — and a separate exam.
Requirements in Rhode Island: confirm current hour and exam requirements directly with Rhode Island Contractors' Registration and Licensing Board (CRLB). Rules update frequently and our data reflects published standards as of early 2025.

The Exam.
Automotive and diesel technician licensing is not universally required by state — ASE certification is the industry standard and is portable across states. Some municipalities require shop licenses even where state licensing is absent. Prevailing wage requirements in Rhode Island apply to most public-sector projects, which ties exam and licensure to wage scale compliance for contractors.
Be honest about pass rates. Many licensing boards do not publish them. When they do, first-time pass rates for journeyman exams in the trades typically run 50–75%. Preparation time varies — most serious candidates spend 60–120 hours on exam prep. Use code books from the correct edition, not what's currently in print.
