You can obtain a copy a driver's manual at a local DMV office. Most states also have their DMV driver manuals online at each state's DMV website.
Driver's manuals cover a number of different topics, including the rules of the road in each state, the application procedure, safety tips, how to read traffic signals and signs, how to handle emergency issues, and how to change a driver's name and address. Manuals also help drivers learn about the effects of driving while under the influence of drugs or alcohol. Some DMV websites also enable individuals to take an online practice test.
