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 from that state's own driver manual, for readers who would rather understand a rule than memorize an answer.
