What's the Passing Score on Wyoming's CDL General Knowledge Test?

40 of 50 questions correct — 80% — passes Wyoming's CDL general knowledge test.

Why the test itself is the cheap part to retake

Wyoming's written knowledge tests carry no fee, so failing and retaking the general knowledge test costs nothing directly out of pocket — unlike a state that charges per attempt.

That doesn't mean failing is free overall, though: it still costs time, and the CLP and skills-test fees paid afterward don't shrink just because the knowledge test itself was free.

Where the real financial stakes actually sit

A $45 Commercial Learner's Permit and an $85 skills exam, paid in advance, come after the knowledge test — both nonrefundable regardless of how the later stages go.

Passing the general knowledge test cleanly the first time keeps that spending on track, rather than adding an avoidable delay before the CLP's mandatory 14-day hold can even start.

Setting a real practice target

Aim for a consistent 90% or better in practice, not just the 80% floor, since test-day pressure tends to shave a few points off a relaxed practice score.

A topic-by-topic breakdown after each attempt — air brakes, combination vehicles, cargo securement — reveals a specific weak spot an overall percentage would otherwise hide.
