How we write and review our content
- Every page has one author, who writes and maintains the text. The byline at the top says who.
- A second person reviews the text against the CBR's course material and the RVV 1990 (the Dutch traffic rules and signs regulations). The byline names them under "Reviewed by".
- When the rules or the exam change, we update the page. "Updated" is the date of the last change to the content, "Reviewed on" the date the page was last checked.
