Driver's License Test Prep

Driver's License Test Prep is a state-by-state knowledge test prep series. We publish a separate guide for each US state and DC, plus a free companion site with practice questions, study guides, and a universal road-signs reference.

What makes us different

• State-specific where it matters. Each state has its own fees, its own GDL rules, its own passing score, its own DUI penalties. Generic test-prep books paper over those differences. We don't.
• Tracked to the manual. Each guide tracks the official state driver manual for its state. When the manual changes, the guide gets a refresh.
• Free where it counts. The practice questions, the signs reference, and the study guides are all free on the site. The book adds the parts a website can't: an offline course you can mark up, and a companion that turns your diagnostic into a study plan that adapts as you practice.

Who writes it

The series is written by Robert Nolan, who builds each guide around the state's official driver manual: the same passing score and the same rules the knowledge test holds you to.
