Wyoming CDL Practice Test

WYDOT sets an 80% pass mark for every written CDL test but doesn’t publish their size. Our practice tests use the usual CDL format: General Knowledge 50 questions (40 to pass), Hazardous Materials 30 (24), Air Brakes 25 (20), and Combination, Tank, Doubles/Triples, Passenger and School Bus 20 each (16).

The October 2024 Wyoming Commercial Driver License Manual: its Wyoming Information pages (who can’t get a CDL, exemptions, restriction codes, CLP and testing rules, renewals, traffic stops, move-over law) and the national CDL text, including Wyoming’s winter driving tips and its 100 to 500 ft school bus amber-light rule.

You retake only the test you failed. The manual lets you try a different version the same day, but no version more than once a day. Written tests stay valid for the term of the CLP.

No. Walk in to a driver exam office; on a busy day you may wait for a free testing station. Only the skills test is booked ahead, and there's no charge for the written tests.

When you've never been licensed in the U.S., your last license was expired, revoked or denied for two years or more, your privilege was revoked, canceled or disqualified, you upgrade your class or add an endorsement, or you remove the L (air brake) or air-over-hydraulic restriction, which also takes a pre-trip and road test.

80% on each of the 8 tests, each graded on its own (General Knowledge: 40 of 50). Every test's numbers are in the table on this page. Always confirm the current tests with the Wyoming Department of Transportation (WYDOT), Driver Services Program. Why 80% in every state →

365 days. You must hold it at least 14 days before the skills test, finish any Entry-Level Driver Training first, and get the CDL before the CLP expires.

Book it by appointment and bring your own representative vehicle: registered, safe, not placarded and with no firearm inside, driven to the site by someone licensed for it. The test has a pre-trip inspection, basic control and a road test.

20/40 in each eye and 70 degrees of horizontal vision in each eye. Worse vision brings a K (intrastate only) restriction; an alternative vision standard program exists for out-of-state driving.

Farm and ranch vehicles within 150 air miles, firefighting equipment, military equipment driven by service members, and personal RVs under 39,001 pounds. These drivers still need a Class C license.

Wyoming Department of Transportation (WYDOT), Driver Services Program lists the current fees for the commercial learner permit, the CDL tests and the license on its official fee page.

WYDOT tests in Casper, Cheyenne, Cody, Evanston, Gillette, Rawlins, Riverton, Rock Springs and Sheridan, and in Afton in season. Third-party examiners exist too, but they may test only their own employees, volunteers or students, and can't charge for it.

Book and pay ahead through oneWYO, at a driver exam office or through the CDL help desk. Cancel at least 24 hours before or the fee is lost, as it is after a failed test, so a retest is booked and paid again. If your entry-level training can't be confirmed by test time, the test is cancelled.

With Passenger or School Bus on the permit, no passengers apart from other trainees and the CDL holder supervising you (School Bus also needs Passenger). With Tank, only an empty tank that holds no hazmat residue. Your supervisor sits in the front passenger seat and holds a CDL for that class.

Not since January 1, 2026. Your examiner sends it through the National Registry and has until midnight of the next day to do so, and Wyoming can't issue a learner permit or CDL until it arrives. A medical certificate lasts two years at most.

Anyone 18 or older with a valid Wyoming driver license. Apply in person at a driver exam office to be photographed, show your documents and, if your type of driving needs one, a DOT medical card, then pass the general knowledge test, any other written tests for your class and a vision screening.

Yes. If you hold a valid U.S. military license, you must pass every written test for the class of license you already hold, and you may not have to complete Entry-Level Driver Training.

No, a personal RV needs a Class C license, but one of 39,001 pounds or more needs the Z endorsement on it. You pass a written test and either a skills test in a similar vehicle or an affidavit of competency signed by someone licensed to drive that weight.

Entry-Level Driver Training for first-time applicants, the TSA security threat assessment, and the hazmat written test. Transferring an out-of-state hazmat endorsement means taking the test again, and Wyoming CDL holders retest if no pass is on record within two years.

Possibly, for driving only inside Wyoming: the state reviews intrastate waivers for drivers who miss the federal standard on vision, hearing, diabetes or a limb, and adds a K restriction. Federal programs, such as the alternative vision standard and the FMCSA's limb certificate, can open out-of-state driving.

Yes, if it's under five years old: the examiner confirms it with TSA, and the Wyoming endorsement runs only for the time left on it, unless you start a new check for a full term. To keep hazmat at renewal you renew in person and pass the hazmat test again each time.

Yes, but without the hazmat endorsement. Allow at least 30 to 60 days for the TSA application and fingerprints. If you take the CDL first, you reapply and pay another license fee to add hazmat once TSA approves, and the license with H isn't released until TSA tells Driver Services you're cleared.

Two serious violations in three years, such as speeding 15 mph or more over, following too closely or texting at the wheel of a CMV, mean 60 days; a third means 120. A major offense, such as DUI in any vehicle or leaving a crash scene, costs a year (three with hazmat), and a second costs the CDL for life.

Drivers with a Passenger or Hazmat endorsement stop at every crossing; other commercial drivers slow down. A crossing violation means a 60-day disqualification, and 120 days for a second.

Start again with a new learner permit, which means passing every knowledge test for the class, holding the permit at least 14 days and passing the skills test. After a lifetime disqualification you can ask to be relicensed after 10 years, but never with hazmat.
