Where the material comes from
Last updated 15 August 2026
This course is assembled out of other people’s work: federal regulation, state licensing manuals, court decisions, government photography, and photographs and footage made by people who chose to license them for reuse. Those licences carry obligations, and this page is part of meeting them.
The teaching material
Federal regulations
Title 49 of the Code of Federal Regulations, read from the electronic CFR, which is the continuously updated version. Where a rule is quoted, it is quoted verbatim and the part and section are named on screen. Federal government works are not subject to copyright in the United States.
The model manual and the state manuals
Most states publish a commercial driver licence manual adapted from the model manual maintained by the American Association of Motor Vehicle Administrators. State manuals and their diagrams are used as reference and are credited to the issuing state agency by manual title, edition, and page or figure number wherever one appears.
Case law
Decisions are read from the courts’ own published opinions and cited by case name, court and year, so any of them can be pulled and read in full. Judicial opinions are in the public domain.
Images, footage and diagrams
Everything shown falls into one of four buckets, and nothing else is used.
- United States government works. Photography and diagrams published by federal agencies, which are free of copyright but are still credited to the agency that made them.
- Creative Commons licensed work. Where a licence requires attribution, the photographer’s name and the licence are shown with the image and repeated in the video description. Where a licence forbids commercial use or derivative works, the image is not used, because this is a commercial channel and the images get resized.
- Licensed stock. Bought under a licence that permits this use.
- Original material. Diagrams, animation and photography made for the course.
Per video credits appear in the video itself and in its description, because that is where somebody watching can actually see them. This page is the standing statement of how the sourcing works.
State agency marks
Agency logos, seals and vehicle liveries are shown to teach recognition: knowing which agency has pulled you over is part of the job. They belong to those agencies, they are used for identification only, and nothing here implies that any state or federal agency endorses, sponsors or approves this course. Federal seals in particular are restricted by 18 U.S.C. 701 regardless of copyright, and are never used on anything resembling a certificate or credential.
Generated imagery
Some illustration and background material is machine generated. It is used for atmosphere, objects and scenes only, and never to depict a document, a regulation, a licence, a form or a page of text. An image generator will render a heading correctly and then invent plausible looking body text underneath it, and an invented regulation on screen is a false statement of law no matter how good it looks.
If a credit is wrong
Tell us and it gets fixed. Attribution errors are treated as errors, not as complaints: a missing or wrong credit is corrected in the video description immediately and in the video itself at the next rebuild. If you hold rights to something used here and want it removed, say so and it comes down while it is sorted out rather than after.
