1. A yellow sign shows a truck on a slope with the legend 7 PERCENT GRADE. What should a driver of a heavy vehicle do?
Show answer
Answer A: Select a lower gear before starting down
The percentage shows how steep the descent is, and choosing a low gear at the top lets the engine hold the vehicle back instead of the brakes overheating.
-
2. A driver is thinking about overtaking a slower vehicle and sees this sign a short distance ahead. What does it mean for that pass?
Show answer
Answer B: The pass must be finished before the restricted section begins
The sign marks the start of a section where passing is prohibited, so a driver may not be on the left side of the road beyond it; any pass has to be completed before that point or not started at all.
-
3. A piece of farm machinery ahead of you is wider than its own lane. What should you do?
Show answer
Answer C: Hold back until you can see far enough to pass safely
Wide equipment leaves no gap inside the lane and may use part of the other side, so a pass needs a long clear view of the road ahead.
-
4. A line of short dashes set closer together than an ordinary lane line runs beside your lane where a ramp leaves the highway. What does a dotted line of that kind convey?
Show answer
Answer A: A warning that the lane is about to change function
Dotted lines give guidance or warning about a downstream change, such as a lane that becomes an exit only lane or a lane line carried across an intersection.
-
5. Compared with dry pavement, how much room does a vehicle need to stop on packed snow?
Show answer
Answer D: Several times as much
Grip on packed snow is a fraction of that on dry pavement, so stopping distance grows several times over. Antilock brakes help you steer, not stop shorter.
-
6. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
7. Besides motorist services and tourist information, a blue sign background is also used for
Show answer
Answer B: evacuation route signing
Blue is assigned to road user services, tourist information and evacuation routes, so hurricane and other evacuation routes are signed in blue.
-
8. You must cross a stretch of water lying across the road that you know is shallow. What is the right technique?
Show answer
Answer A: Slow down before you reach it and cross steadily in a low gear
Slow before the water, then keep a steady low speed so you do not throw water over the engine or lose steering. Test the brakes gently once you are through.
-
9. You are parked legally, but a police officer tells you to move the vehicle. What should you do?
Show answer
Answer B: Move it as directed, because an officer overrides the signs
Directions from a police officer or a firefighter take precedence over signs and markings, whether they are directing traffic or clearing a street.
-
10. You and a driver coming from the opposite direction reach a four-way stop at the same time and you are both going straight ahead. What happens next?
Show answer
Answer D: Both of you may move off together, because your paths do not cross each other
Opposing vehicles that are both going straight do not cross paths, so they can move off together once the intersection is clear.
-
11. How much should you normally reduce your speed on a road covered with packed snow compared with dry conditions?
Show answer
Answer C: By about half
Packed snow roughly doubles the distance needed to stop, so a common guideline is to cut speed by about half. On ice, slow to a crawl.
-
12. You hear a bang and one of the front tires deflates while you are on the highway. What happens to the vehicle?
Show answer
Answer D: It pulls strongly toward the side that failed
The collapsed tire drags heavily on that corner, so the vehicle veers toward it. Hold the wheel firmly, keep your line and let the speed fall before leaving the road.
-
13. You have parked but your car sits across the line into the next space. What should you do?
Show answer
Answer B: Pull out and park again fully inside one space
A car over the line takes a space away from someone else and leaves too little room for the doors of the vehicles beside it.
-
14. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?
Show answer
Answer A: Wait until the gates rise completely and the lights go out
Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.
-
15. When is a driver at the highest risk of falling asleep at the wheel?
Show answer
Answer B: Late at night, early morning and mid afternoon
The body clock produces its deepest dips in alertness in the small hours and again in the middle of the afternoon, and crash records follow those dips.
-
16. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
17. What should you do as you approach your exit from a roundabout?
Show answer
Answer A: Signal right and check the crosswalk for pedestrians before leaving
A right signal tells following drivers and waiting drivers that you are leaving, and pedestrians cross at the exit leg, so the crosswalk must be checked.
-
18. What is the safest way to pass a bicyclist on a road with two lanes going your way?
Show answer
Answer D: Change lanes completely, as you would for a car
A bicycle is entitled to the room a vehicle needs, and moving into the next lane gives the rider space to swerve around a drain or a pothole.
-
19. What does a NARROW BRIDGE warning sign tell a driver?
Show answer
Answer A: The bridge is tighter than the road leading up to it
A narrow bridge still carries both directions, but with much less clearance than the approaches, so drivers should slow and hold their lane position carefully.
-
20. How does braking distance change if you double your speed?
Show answer
Answer D: It grows much more than twice as long
Braking distance increases with the square of speed, so doubling speed roughly quadruples the distance needed to stop.
-
21. You have a steady green ball to turn left, and the oncoming traffic gets a green left arrow. What does that mean for you?
Show answer
Answer C: Oncoming vehicles will turn across your path, so you must wait
A green ball is permissive, so when the oncoming side receives a protected arrow those vehicles have priority and you must yield until they clear.
-
22. A 20-year-old Nevada driver tests at .04 percent alcohol concentration. What happens to the driving privilege?
Show answer
Answer C: It is suspended, because Nevada acts against drivers under 21 at .02 percent or more
For a driver under 21, a test showing .02 percent or more but less than .08 percent leads to an administrative suspension of the driving privilege.
-
23. A turn restriction sign at the corner shows a range of times below the symbol. What does that mean?
Show answer
Answer A: The turn is banned only during the hours shown on the sign
Times posted under a regulatory symbol set the period during which the restriction applies; outside those hours the movement is permitted.
-
24. 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.
-
25. On a regulatory sign, what does a red circle with a diagonal slash drawn over a symbol mean?
Show answer
Answer D: The movement or action shown by the symbol is prohibited
A red circle with a diagonal slash is the standard way of showing that the movement pictured inside it, such as a U-turn or a right turn, is not allowed.
