Washington permit test practice
Mr. Driver’s Ed is a free study app for the written knowledge test you take for a learner’s permit in Washington. It has no ads, and every question in it cites the page of the official handbook it was written from, so you can check any answer against the book. Here are ten of its Washington questions, each with its answer, the reason, and its citation.
Ten Washington practice questions
These are taken word for word from the app’s Washington question bank. The handbook is Washington State Driver Guide. In this handbook one printed page number can appear on two different pages, so each citation gives the page’s position in the PDF file instead.
