Driver's education, driver's ed, or driving tuition or driving lessons is a formal class or program that prepares a new driver to obtain a learner's permit or driver's license. The formal class program may also prepare existing license holders for an overseas license conversion or medical assessment driving test or refresher course. It may take place in a classroom, in a vehicle, online, or a combination of the above. Topics of instruction include traffic code or laws and vehicle operation. Typically, instruction will warn of dangerous conditions in driving such as road conditions, driver impairments, and hazardous weather. Instructional videos may also be shown, demonstrating proper driving strategies and the consequences for not observing the rules.
