1. 1. About what share of alcohol in the body is eliminated by the liver?

   1. About 90 percent eliminated by the liver
   2. About 50 percent eliminated by the liver
   3. About 10 percent eliminated by the liver
   4. Nearly all eliminated through the lungs only
   Show answer

   About 90 percent eliminated by the liver. About 90 percent of the alcohol in the body is eliminated by the liver, at a constant rate of about one drink per hour that is about the same for all persons. Halving that share, dropping it to a tenth, or assigning elimination mainly to the lungs misstates the pathway. Because the rate cannot be hurried, showering, coffee, and exercise are useless for sobering up, and only time reduces blood alcohol levels.

2. 2. A green-and-white sign ahead lists a destination and its distance. What job is that sign doing?

   1. Guide signs set speed limits and turn requirements
   2. Guide signs provide directions, routes, and information
   3. Guide signs warn drivers about hazards ahead
   4. Guide signs identify railroad crossings and track numbers
   Show answer

   Guide signs provide directions, routes, and information. Guide signs help drivers understand where they are, which road they are using, and how to reach a destination. They provide directions, routes, and related information rather than setting speed limits or turn requirements. Diamond-shaped signs generally warn about hazards, while railroad signs identify crossings and may show track information. The color of a guide sign is determined by the type of information it gives, so the destination and distance on this sign point to its guidance function.

3. 3. After parking on a hill, which steps complete the routine before leaving the vehicle?

   1. Engine idling, keys left, doors unlocked
   2. Engine off, keys left, windows lowered fully
   3. Engine off, keys taken, and car locked
   4. Engine idling briefly, keys taken, car unlocked
   Show answer

   Engine off, keys taken, and car locked. Finishing a hill park means switching the engine off, taking the keys along, and locking the car after wheels and brake are set. Leaving the motor idling, abandoning keys inside, dropping every window, or walking away with doors unlocked each drops part of that closing routine and invites theft or an unattended roll. Run through brake, wheel angle, engine, keys, and locks as a single checklist before stepping away from the vehicle.

4. 4. In fog, what speed difference makes crash chances extremely high?

   1. More than 5 mph difference from other traffic
   2. More than 15 mph difference from other traffic
   3. More than 10 mph difference from other traffic
   4. More than 25 mph difference from other traffic
   Show answer

   More than 15 mph difference from other traffic. Fog punishes speed mismatch: crash chances run extremely high whenever a vehicle's speed differs from other traffic by more than 15 mph. Five or 10 mph understates the stated threshold, and 25 waits far too long to react. Use low beam headlights, add front fog lights where fitted, reserve red rear fog lights for heavy fog, and stop at the nearest safe place when a great speed difference threatens. Scan for taillights and slow vehicles.

5. 5. What must a driver remember about judging an oncoming motorcycle before turning left?

   1. Look again and judge motorcycle speed before turning
   2. Motorcycles always travel slower than cars nearby
   3. Turn quickly since motorcycles can stop faster
   4. Sound horn and turn if rider does not wave
   Show answer

   Look again and judge motorcycle speed before turning. Left turns in front of oncoming motorcycles cause a large share of car cycle crashes, because drivers miss the motorcycle or misjudge its speed. Assuming slower travel, turning quickly on superior motorcycle braking, or demanding a wave all skip the directed double look. Identify the motorcycle as a critical object, fix its speed, and confirm a signaled rider truly turns rather than continuing straight, since motorcycle signals rarely cancel automatically.

6. 6. Your gas pedal sticks while you are driving. After concentrating on steering, what should you try next?

   1. Pump the brake pedal rapidly until the car slows
   2. Try to free the stuck pedal with your foot
   3. Shift into reverse while the car is moving
   4. Turn the key to lock to cut engine power
   Show answer

   Try to free the stuck pedal with your foot. Keep your eyes on the road and keep steering while you try to free the stuck pedal with your foot. If the pedal will not come loose, push in the clutch or shift to neutral, use the brakes, stop at the nearest safe place, and turn off the ignition. Pumping the brakes rapidly belongs to a brake failure drill, and turning the key toward lock while moving can lock the steering. Once stopped, find what caused the sticking and have it repaired before driving again.

7. 7. During an Interstate emergency stop at night, what should mark the vehicle besides flashers?

   1. Headlights left on high beam facing traffic
   2. A passenger waving a flashlight in the lane
   3. Flares or reflectors placed at night
   4. Doors opened wide on the traffic side door
   Show answer

   Flares or reflectors placed at night. Four way flashers run during an Interstate emergency stop, and night adds flares or reflectors to warn approaching drivers earlier. Blinding traffic with high beams, sending a passenger into the lane with a flashlight, or swinging traffic side doors open manufactures fresh hazards instead of marking the stopped car. Set the warning devices from the safe side, keep occupants away from moving lanes, and stay alert for secondary crashes nearby.

8. 8. For a restricted license based on extreme inconvenience, how far from school or employment must the applicant live?

   1. At least one mile from school or employment
   2. At least ten miles from school or employment
   3. Five or more miles from school or employment
   4. At least twenty miles from school or employment
   Show answer

   Five or more miles from school or employment. A restricted license for extreme inconvenience is for an applicant aged 14 or 15 whose household faces a real travel hardship. The applicant must already have held an instruction permit and must live five or more miles from school, employment, or both. The Wyoming Highway Patrol approves these applications. The license then works only from 5 a.m. to 8 p.m. and within 50 miles of home, and a moving violation or driving outside those limits brings suspension. One mile understates the distance test, while ten and twenty miles raise it beyond the stated line.

9. 9. What should be done if a vehicle spins out ahead on an icy hill?

   1. Pass the spun vehicle on the icy shoulder
   2. Stop and help push the vehicle uphill again
   3. Turn around on the hill and descend quickly
   4. Stay in line and wait for a snowplow
   Show answer

   Stay in line and wait for a snowplow. A vehicle spun out on an icy hill is a signal to stay in line and wait for a snowplow to clear the way, reaching the top quicker than improvising. Passing on the icy shoulder, pushing by hand on slick footing, or turning around mid hill all risk joining the blockage. Patience defines ice and snow driving generally: start slowly and steadily, point front wheels straight, and expect four wheel drive vehicles to skid on sudden power changes too.

10. 10. Most fatal heavy vehicle crashes are caused by which driver, per cited statistics?

    1. Most are caused by the passenger vehicle driver
    2. Most are caused by the heavy vehicle driver
    3. Responsibility is split equally in most cases
    4. Most are caused by road design failures cited
    Show answer

    Most are caused by the passenger vehicle driver. National Highway and Traffic Safety Administration statistics cited in the manual attribute most fatal crashes between heavy vehicles and other vehicles to the passenger vehicle. Assuming truck drivers cause most, splitting blame evenly, or blaming road design contradicts that finding and the behavior it targets. Trucks are not large cars: accelerating, braking, hill climbing, lane switching, and turning all take distances and timing passenger drivers routinely misjudge.

11. 11. What does a steady amber light require if a driver can stop safely?

    1. Speed up to enter before the light turns red
    2. Proceed at the same speed through the junction
    3. Stop only after crossing the stop line area
    4. Stop before entering the intersection if possible
    Show answer

    Stop before entering the intersection if possible. A steady amber light means stop before entering the intersection if possible, and proceed carefully only when stopping safely is impossible. Speeding to beat the red, cruising through unchanged, or stopping beyond the stop line all misapply the warning stage between green and red. Green itself permits entry only when the way is clear with yielding to vehicles and persons already in the intersection, so amber is the last orderly chance to halt.

12. 12. Why is driving 10 to 15 mph slower than traffic hazardous for poor night vision drivers?

    1. Slower driving is always safer in every context
    2. Other drivers expect slow vehicles at night hours
    3. Large speed differences from traffic create danger
    4. The hazard is only fuel waste from slow travel
    Show answer

    Large speed differences from traffic create danger. Compensating for poor night vision by driving far slower creates its own hazard, because speeds 10 to 15 mph below other traffic reproduce the speed difference danger named in fog guidance. Slower is not automatically safer, night expectations do not protect a slow vehicle, and fuel waste is not the stated concern. The better compensation limits driving to slower speeds on well lighted streets or to daytime only, matching exposure to actual visual ability.

13. 13. Why must drivers stay alert even when they hold the right of way?

    1. Others may fail to yield and crashes must be avoided
    2. Right of way holders are liable for all crashes
    3. Traffic laws reward insisting on right of way always
    4. Yielding when entitled is prohibited by statute law
    Show answer

    Others may fail to yield and crashes must be avoided. Holding the right of way never suspends alertness, because others may fail to yield and every driver should do everything possible to avoid a crash. Entitled drivers are not automatically liable, insistence is not rewarded, and defensive yielding violates no statute. The laws only indicate who must yield rather than granting possession, bicyclists count as vehicles within the same framework, and recognizing other vehicles and pedestrians early is what keeps a legal claim from becoming a collision.

14. 14. Who cannot obtain a Wyoming driver license under the eligibility list?

    1. Persons who wear corrective lenses while driving
    2. Persons over 21 years of age applying first time
    3. Persons whose privileges are suspended in any state
    4. Persons licensed in a compact member state before
    Show answer

    Persons whose privileges are suspended in any state. Eligibility excludes persons whose driving privileges are suspended, canceled, denied, or revoked in Wyoming or any other state, verified through the Problem Driver Pointer System on all applicants. Corrective lenses merely add restriction B, first time applicants over 21 are routine, and compact state licensing is honored rather than disqualifying. The same list bars persons under 16, examination failures, persons judged legally incompetent, habitual alcohol or substance users, and immigration law violators.

15. 15. Before turning in front of a motorcycle signaling a turn, what should be confirmed?

    1. Assume the signal means the rider will turn
    2. Turn quickly since the rider can stop faster
    3. Wave the rider through then turn behind them
    4. Be sure the rider is turning, not going straight
    Show answer

    Be sure the rider is turning, not going straight. Motorcycle turn signals rarely cancel automatically, so a blinking signal may be stale; confirm the rider actually turns rather than continuing straight before pulling into the intersection ahead of the bike. Assuming the turn, relying on motorcycle braking, or waving the rider through substitutes hope for that confirmation. Motorcyclists hold the same rights and full lane width as other vehicles, and the car driver who misreads the signal causes the classic left turn crash.

16. 16. By how much should speed be reduced on a wet road under Wyoming guidance?

    1. Reduce speed by at least 15 to 20 mph
    2. Reduce speed by at least 5 to 10 mph
    3. Reduce speed by half on any wet road
    4. Keep posted speed and increase following gap only
    Show answer

    Reduce speed by at least 5 to 10 mph. Wet pavement calls for cutting speed by at least 5 to 10 mph from the dry road pace. Slashing 15 to 20 mph overshoots the stated adjustment, halving speed belongs to packed snow, and holding posted speed while only adding gap ignores the explicit reduction. Match the remedy to the surface: wet gets the modest cut, packed snow takes half, and ice demands a crawl. Recheck grip gently where traffic permits when conditions look doubtful.

17. 17. Where should pedestrians cross at a roundabout in Wyoming?

    1. Pedestrians should cross only in crosswalks
    2. Pedestrians may cross at any point on circle
    3. Pedestrians cross through the central island area
    4. Pedestrians should cross behind entering vehicles only
    Show answer

    Pedestrians should cross only in crosswalks. Pedestrians at a roundabout cross only in the marked crosswalks, where approaching drivers expect them and must yield. Crossing at random points, cutting through the central island, or stepping behind entering vehicles places walkers where circulating drivers are scanning left for gaps instead. Drivers slow and yield to pedestrians in those crosswalks both on entry and while exiting, so walkers should stay within the paint and cross one approach at a time.

18. 18. Why is loitering in a truck's blind spot while passing dangerous?

    1. The truck driver can see and will compensate
    2. The truck driver cannot take evasive action safely
    3. Loitering saves fuel for the passing vehicle
    4. Cruise control passing is recommended beside trucks
    Show answer

    The truck driver cannot take evasive action safely. A passenger vehicle lingering in a truck's blind spot, perhaps on cruise control barely faster than the truck, leaves the truck driver unable to take evasive action without striking an unseen car. Assuming the high seated driver sees everything ignores the large side and rear No Zones trucks carry, and fuel saving never justifies the exposure. Maintain consistent speed, pass with sufficient pace, and stay out of No Zones rather than traveling inside them.

19. 19. How long does moving a foot from accelerator to brake take in the stopping sequence?

    1. About one quarter of a second to move foot
    2. About two seconds to move the foot over
    3. No measurable time to move the foot across
    4. About three quarters of a second to move foot
    Show answer

    About three quarters of a second to move foot. Identifying a danger, predicting what could happen, and deciding what to do takes at least one second before the execution step begins. Execution starts by moving a foot from the accelerator to the brake, and that foot movement alone takes about three quarters of a second. A quarter second makes the move sound quicker than it is, two seconds stretches it well past the stated time, and zero time ignores a real delay. At 55 mph, a passenger vehicle needs roughly 130 to 140 feet to stop after braking begins.

20. 20. How much safety benefit does a hands-free cell phone give over a hand-held phone while driving?

    1. It removes nearly all distraction from a call
    2. It makes long conversations safe at highway speed
    3. It allows a driver to read messages without risk
    4. It provides little safety benefit over hand-held phones
    Show answer

    It provides little safety benefit over hand-held phones. Talking on a phone takes attention from identifying hazards, predicting what others may do, and deciding in time, whether the phone is held or mounted. Federal studies link phone use of both kinds with crashes and near misses, and hands-free equipment gives little safety gain because conversation itself distracts. Reading messages is a separate danger and is prohibited while operating a vehicle. The safer habit is to pull well off the highway and stop before calling or texting, then return full attention to traffic before merging back.
