Wyoming CDL Practice Test

Correct answer: 18 years old

You must be at least 18 to hold a Wyoming CLP or CDL — the manual lists "persons under 18 years of age" among those who cannot get a Wyoming CDL. Driving a CMV in interstate commerce still requires you to be 21 (49 CFR 391.11); an 18-to-20-year-old is limited to intrastate operation.

Correct answer: 365 days

A Wyoming CLP is valid for 365 days. You must obtain and pay for your CDL before the CLP expires, and you must hold the CLP for at least 14 days before you may take the skills test.

Correct answer: At least 14 days

The driver must hold the CLP for at least 14 days before skills testing. This matches the federal minimum in 49 CFR 383.25 and gives you time to practice with a qualified CDL holder seated beside you.

Correct answer: $45

A Wyoming CLP of any class costs $45. The manual’s fee table lists the CLP at $40 plus a $5 technology fee imposed on all driver licenses and CDL skills tests, for the $45 total shown on WYDOT’s fee schedule. Fees are subject to change.

Correct answer: 80 percent

All Wyoming CDL written tests are multiple choice, and the passing score is 80 percent — the federal standard in 49 CFR 383.135 that applies in every state and to every section (General Knowledge, Air Brakes, and Combination).

Correct answer: You may take a different version the same day, but no single version may be taken more than once in a day

An applicant who fails one version of a written test may take another version the same day, but each version cannot be taken more than once in the same day. You only have to retake the test you failed, not the ones you already passed.

Correct answer: It is by appointment only, and the $85 fee is forfeited if you fail or miss the appointment without cancelling

Wyoming skills tests are conducted by appointment only for an $85 fee (an $80 base plus the $5 technology fee). If you fail, or fail to appear without cancelling with the exam station at least 24 hours ahead, the fee is forfeited and you must reschedule and pay again.

Correct answer: The applicant — Wyoming does not furnish test vehicles, and it must represent the class applied for

The state does not furnish vehicles for skills testing. You must supply a legally registered, safe vehicle representative of the class of license you are seeking, and it must be driven to the site by someone licensed for that class. Placarded vehicles may not be used.

Correct answer: There is a firearm in the vehicle

A skills test will not be administered if there is a firearm in the vehicle. The test vehicle must also be legally registered, meet minimum safety standards, and not be a placarded vehicle.

Correct answer: 20/40 in each eye, with or without correction

A reading of 20/40 in each eye is required. If your best corrected vision is worse than 20/40 in each eye, you receive a "K" restriction limiting you to intrastate driving only. Glasses or contacts worn during the screening must be worn whenever you drive.

Correct answer: No — a sleep debt can only be paid off by sleeping; you cannot overcome it with willpower

Sleep is not like money — you cannot save it up ahead of time. If you do not sleep enough you build a sleep debt that can only be paid off by sleeping. You cannot overcome it with willpower and it will not go away by itself.

Correct answer: Between midnight and 6 a.m.

Your body is used to sleeping during certain hours. Many heavy motor vehicle accidents occur between midnight and 6 a.m., when tired drivers can easily fall asleep — especially drivers who do not regularly drive at those hours.

Correct answer: A brief nap of four or five seconds — at 55 mph that is more than 100 yards traveled with no one driving

If you are drowsy you can have "micro-sleeps" — brief naps lasting around four or five seconds. At 55 mph that is more than 100 yards. Sleep is not voluntary: you can fall asleep and never even know it.

Correct answer: Stop and sleep, or at least pull off at a safe place and take a nap

When your body needs sleep, sleep is the only thing that will work. Stop at the first signs of sleepiness, even if earlier than planned. If you cannot stop for the night, pull off at a safe place and take a nap — a half-hour nap beats a half-hour coffee stop.

Correct answer: Keep a window or vent cracked open, or use the air conditioner, to stay cool and alert

A hot, poorly ventilated vehicle can make you sleepy. Keep the window or vent cracked open or use the air conditioner. Also take short breaks before you feel really drowsy — stop, walk around, and inspect your vehicle.

Correct answer: Do not drive — but in an emergency you may drive to the nearest place where you can safely stop

If you become so ill that you cannot operate a motor vehicle safely, you must not drive. However, in case of an emergency, you may drive to the nearest place where you can safely stop.

Correct answer: Rest — sleep is the only thing that can overcome fatigue

Sleep is the only thing that can overcome fatigue. Do not rely on coffee or caffeine, and do not count on the radio, an open window, or other tricks to keep you awake — they will not make a tired driver alert.

Correct answer: Any road condition or road user that is a possible danger

A hazard is any road condition or other road user — driver, bicyclist, or pedestrian — that is a possible danger. Seeing it early gives you time to act before it becomes an emergency.

Correct answer: It gives you more time to act and avoid a crash

Seeing a hazard early gives you time to check mirrors, signal, and change speed or lanes smoothly. A driver who does not see it until the last moment must react suddenly, which is much more likely to lead to a crash.

Correct answer: The driver is uncertain and might suddenly return to the highway in front of you

The braking, uncertain driver might suddenly return to the highway. Right now the car is a hazard; if it cuts in front of you, it becomes an emergency. Plan an escape while it is still only a hazard.
