1. A highway lane is marked with a large white diamond and signed as a high-occupancy vehicle lane. Who may use it?
Show answer
Answer B: Only vehicles carrying at least the number of occupants shown on the sign, during the posted hours
The diamond marking identifies a preferential lane whose occupancy requirement and hours of operation are stated on the accompanying signs.
-

General service signs cover facilities such as hospitals, fuel, food, lodging, camping, telephones and rest areas, all shown in white on blue.

3. Under Wyoming statute, what is the default speed limit on an unpaved road for which no specific maximum speed limit has otherwise been established?
Show answer
Answer C: 55 miles per hour
Wyoming statute sets 55 miles per hour as the default maximum on an unpaved road for which no other maximum speed limit has been established.
-
4. You are the first to arrive at a crash on a rural road. What should you do first?
Show answer
Answer C: Park well clear of the scene, put on your hazard lights and call for help
Getting trained help on the way and keeping the scene visible does more good than anything an untrained bystander can do.
-
5. Heavy trucks have worn deep ruts into a highway lane and rain has filled them. What is the danger?
Show answer
Answer D: Water collects in them, so the tires can lose contact with the road
Ruts hold standing water long after the rest of the lane has drained, which makes them the most likely place to start hydroplaning.
-
6. You are in the middle lane of a one-way street with three lanes when a police car approaches from behind with lights and siren. What should you do?
Show answer
Answer C: Pull to the nearest curb and stop clear of the lanes
On a one-way street you clear to whichever curb is closest, so the emergency vehicle gets a clear path down the open lanes.
-
7. A deer crosses the road in front of you and disappears into the trees. What should you expect?
Show answer
Answer B: That other deer are likely to follow it across the very same stretch of road
Deer usually move in groups, so one crossing the road is a warning that more may follow.
-
8. You have fitted small convex blind spot mirrors to the door mirrors. What is true of them?
Show answer
Answer A: They help a good deal, but you should still look over your shoulder as well
Add-on mirrors reduce but do not remove the blind spot, and they make vehicles look smaller and further away.
-
9. A mixed drink is made with two shots of spirits. How much alcohol is that?
Show answer
Answer C: About two standard drinks
A standard drink is a fixed amount of pure alcohol, so a glass poured with two measures counts as two drinks however it is served.
-
10. What should you do about snow and ice on your vehicle before driving?
Show answer
Answer C: Clear all glass, mirrors and lights, and the roof and hood as well
Snow left on the roof or hood slides onto your windshield when you brake and blows into the path of drivers behind you, and covered lights make your vehicle hard to see.
-
11. You cannot avoid a wide puddle that covers only the right half of your lane. What should you expect?
Show answer
Answer D: The water can tug the vehicle toward that side, so slow before it and grip the wheel
Water dragging on the tires of one side only pulls the vehicle that way. Reduce speed before you reach it and hold the wheel firmly.
-
12. Your vehicle has antilock brakes. What should you never do in an emergency stop?
Show answer
Answer A: Pump the pedal up and down
The system already releases and reapplies the brakes many times a second. Pumping the pedal interrupts it and makes the stop longer.
-
13. In heavy stop-and-go traffic, why does using both lanes right up to a merge point help?
Show answer
Answer D: It stores the queue in two lanes, so the backup is shorter
Filling both lanes halves the length of the queue and keeps it away from the traffic upstream, which is why alternating at the merge point works better when traffic is slow.
-
14. You arrive at an intersection where the traffic signals are completely dark after a power failure. What should you do?
Show answer
Answer A: Treat the intersection as an all-way stop and take turns
When a signal is dark or out of order, drivers on every approach must stop and proceed in turn, exactly as at a four-way stop.
-
15. A grade crossing is marked only with a crossbuck and has no lights or gates. What does the crossbuck require of you?
Show answer
Answer C: Yield to rail traffic and cross only when no train is approaching
The crossbuck requires road users to yield the right-of-way to rail traffic, so you must look and listen and be ready to stop.
-
16. You have turned right into the nearest lane but you need the left lane soon. When should you move over?
Show answer
Answer A: After the turn is finished, once you have checked mirrors and blind spot
Complete the turn in the proper lane first, then make a normal lane change with mirror and blind spot checks once you are established on the new street.
-
17. In a normal signal cycle, what comes after a steady red indication?
Show answer
Answer A: A green indication that starts the next movement
Yellow is a warning that a movement is ending, so it never precedes a green; a red is followed by a green or a green arrow.
-
18. When is a child ready to use a vehicle seat belt without a booster seat?
Show answer
Answer A: When the lap belt lies across the upper thighs and the shoulder belt crosses the chest
Belt fit, not age, decides readiness. Until the child is tall enough for the lap belt to sit on the thighs and the shoulder belt on the chest, a booster is needed.
-
19. It is cold and the road looks wet, but you notice the tires of vehicles ahead are throwing up no spray. What does this suggest?
Show answer
Answer B: The surface has frozen and is probably icy
Water throws spray, but ice does not. A shiny road with no spray in freezing temperatures is a strong sign of black ice, so slow down and avoid sudden inputs.
-
20. Why are tall vehicles such as SUVs and vans at extra risk in sudden steering maneuvers?
Show answer
Answer B: Their higher center of gravity makes them more likely to roll over
The higher a vehicle's mass sits, the more it leans in an abrupt turn, and a sharp swerve can tip it over. Smooth, gradual steering inputs are essential in tall vehicles.
-
21. Your engine stalls while you are driving in traffic. What is the correct response?
Show answer
Answer A: Shift to neutral, try to restart it, and steer and brake toward the side of the road
With the engine off, power steering and power brake assistance fade, so steering and braking take more effort but still work. Neutral lets you attempt a restart while you coast to safety.
-
22. What will the driver have to do at the point this sign refers to?
Show answer
Answer C: Slow down and let conflicting traffic go first, stopping if that is what it takes
Further along, the driver has to let conflicting traffic and pedestrians go first, reducing speed and stopping whenever that is necessary to avoid interfering with them.
-
23. Does Wyoming's handheld texting ban apply to a law enforcement officer using a device while performing official emergency-response duties?
Show answer
Answer C: No, the statute exempts a person operating an emergency response vehicle making necessary official communications
Wyoming statute exempts a person operating an emergency response vehicle from the texting ban while making communications necessary to official emergency-response duties.
-
24. In plain words, what is understeer?
Show answer
Answer B: The vehicle keeps going straight even though the wheels are turned
Understeer means the front tires have run out of grip, so the vehicle takes a wider line than the one you steered.
-
25. You stop behind another vehicle at a traffic light. How much space should you leave?
Show answer
Answer D: Enough to see where its rear tires touch the pavement
Seeing the rear tires on the road leaves room to steer around the vehicle if it stalls, and gives a cushion if you are struck from behind.
