The actual driving knowledge test is not available online, but most states offer practice tests on their state division of motor vehicle websites. In addition, websites such as DriverKnowledge.com and Driving-Tests.org offer practice driving knowledge tests based on the selected state.
To access the practice driver knowledge test on DriverKnowledge.com, the user clicks on the Start Your DMV Driving Test button. He then clicks on the state for which he wishes to take the practice test, and he receives a list of tests specific to signs or rules that he can take. Tests are available primarily in English, but there is at least one Spanish option as well. The website also provides information regarding the procedures and costs involved in obtaining a license in the selected state.
At Driving-Tests.org, clicking on the Start button provides the user with a list of states. After choosing the desired state, the user chooses from a number of tests on general knowledge, signs, and fines and limits. Test lengths range from 25 to 150 questions. Most are in English, but at least one Spanish-language test is available. This page also presents an FAQ covering the procedures and documentation necessary to obtain a driver's license in the state.
