### Driving as well as fixing?

Diesel mechanics who road-test or move trucks are often asked to hold a commercial driver's license. If that fits your plans, [VerifiedCDLSchools.com](https://verifiedcdlschools.com/) lists CDL training providers and checks them against the FMCSA Training Provider Registry.

Training & tuition

## What training costs

Tuition comes only from published College Scorecard figures. Apprenticeship sponsors do not publish tuition in federal files, so they show “Contact program.”

| Schools with published tuition (775) | $544 | $4,770 | $58,300 | College Scorecard annual tuition & fees (in-state low end; out-of-state high end where they differ) |
| Registered apprenticeship sponsors (16) | Contact program | | | Not published in the DOL file. Registered apprenticeships are usually paid jobs with related classroom instruction. |
Ranges are computed only from rows with a sourced figure. We never estimate tuition.
