Hi all. Very informative thread. However, be aware that not all Texas DMV Offices require a Road test to upgrade from a Class C to a Class B Non CDL License. I called around several DMV Offices and while most required both a written and a road test, one office did not require a road test. When I challenged them and said all other offices seemed to require a Road Test, they responded that it was at the discresion of the Manager at each office. So I travelled a little further a got an upgrade to a Class B Non CDL with just a written test.
So call a few different Texas DMV offices, you may be able to avoid the Road Test.
