Finally got through the WYDOT written knowledge exam and I'm relieved it's behind me. I failed twice before passing with an 82% and the main issue was underestimating how Wyoming-specific some of the rules are. The standard traffic law stuff is straightforward but there are questions about mountain driving, wildlife hazards, and winter road conditions that you won't find in generic prep materials.
My third attempt I spent about 3 weeks focusing specifically on Wyoming statutes rather than just general driving rules. I also went through the Wyoming Driver's Manual cover to cover twice, which I'd skipped before assuming I already knew most of it. There's content in there about passing on two-lane highways and rural intersection rules that showed up directly on the test.
The test center experience was fine — they're efficient and the computer interface is easy to navigate. You get 25 questions and need 20 correct, which sounds manageable but the wrong answer choices are designed to trip you up if you're guessing.
If you're preparing, don't skip the signs and signals section. I had at least 6 questions just on regulatory and warning signs and some of them were pretty obscure Wyoming-specific markings.
That 20/25 passing threshold feels lenient until you realize how the distractors are written. I got two questions where I was 100% sure of my answer and still got them wrong when I reviewed.
The wildlife and mountain sections got me on my first attempt too. I grew up in Wyoming and still missed three questions about snow chain requirements. The manual wording is very specific.
The signs section is no joke. I drilled those separately using flashcards for about a week and it definitely helped. Some of those regulatory signs look almost identical to each other.
