Like the official knowledge test questions, our practice questions are based on your state's official DMV manual, but they cover even more topics. We have seen many real DMV tests and read many different versions of your state’s driver manuals.
Although the official Department of Motor Vehicles does not make the official questions public, we can confidently say that we know what your DMV wants to ask on the test and what topics they want to test you on. We actually "over-prepare" you so that the official exam will seem simple by comparison.
It's very likely that the questions you'll get at the DMV will be about the same concepts, since both the official test and our practice tests are based on the same source (official manual). However, you should be prepared that the questions on the official test will be worded differently. Make sure you read the question carefully and pay special attention to the ones containing a negation or "all/none/some/any of the above" clauses.
