We found the PDF from the TxDOT website which has the official Texas Driver Handbook (2017). Here is that link:

From the “Introduction” section of that resource:
The Texas Department of Public Safety, Driver License Division, is committed to creating a faster, easier, and friendlier driver license experience and a safer Texas. One step toward achieving these important goals is to continu-ously improve the Texas Driver Handbook by providing you with accurate information on traffic laws, clear images of road signs, examples of common driving situations, and general safety tips. We have also included special tips to emphasize important information you need to know.Although the Texas Driver Handbook has been revised, its primary purpose remains the same: 1) to help you qualify for a Texas driver license, and 2) to help you become a safer driver.The information contained in this handbook is not an official legal reference to Texas traffic laws. The information provided is only intended to explain applicable federal and state laws you need to understand in order to success-fully operate a motor vehicle in Texas. If you would like to know the actual language of any traffic or criminal laws referenced in this handbook, please refer to the Texas Transportation Code and Texas Penal Code. Once you receive your Texas driver license, keep this handbook as a reference on traffic safety and update it as needed. The Texas Legislature meets every two years and regularly makes changes to traffic laws.
If you are 18 years of age to 24, and would like to get a drivers license in Texas, then you have to take a 6 hour adult driving course either at a local driving school or online. Should you take the online option then the State has several vendors who are authorized to sell the online course before you can get your learner’s permit. One such company is Drivers Education of America, and here is a video explaining the benefits of the online course:
You also can take such a course at a local driving school such as 1-2-3 Driving School, serving the East Dallas/Garland/Mesquite/Plano/Richardson/Wylie/Murphy area: https://goo.gl/maps/6hDjrLdhdFD8sShaA
