Wow, test was a breeze this time. A note for others: There are two manuals. The first is a large newsprint type ‘Texas Commercial Motor Vehicle Drivers Handbook’ which has *everything* in it. Good to read through, familiarize, and reference. For actual studying for the test, it is best to use the second book, a school bus yellow ‘Texas Drivers Handbook’, chapter 15. Also note Chapter 8–3 for the speed/vehicle chart.
Also, for record, a ‘non-commercial’ license is called a Class A (or B) exempt.
