CDL Knowledge Tests

New Mexico MVD provides study material that allows you to see what material the Federal Government requires you to know before they can issue a CDL endorsement to your license.  CDL Knowledge Testing is how MVD determines that you have read the material and more importantly that you understand it.  In & Out MVD offers several CDL Knowledge Tests, however, you must specify and choose the test that pertains to the class of CDL and endorsement you are applying for.  Please know that In & Out MVD does not offer the CDL Skills Test, only the CDL Knowledge Tests.
