1. A small plaque mounted under this sign shows a numeral such as 2 or 3. What does that numeral report?
Show answer
Answer A: How many sets of tracks the crossing carries
The plaque states the number of tracks at that location, which is a warning that a second train may be running on another track behind the first.
-
2. You feel drowsy, so you open a window and turn the radio up. What does that achieve?
Show answer
Answer B: Very little, because the drowsiness comes back
Cold air and loud music are not sleep, so the alerting effect lasts a minute or two and the driver is soon just as sleepy and closer to a lapse.
-
3. You are about to slow down sharply for a turn. Which check comes first?
Show answer
Answer A: A look in the mirror to see how close the traffic behind you is
Any hard slowing needs a mirror check first, because the driver behind is the one who has to react to it.
-
4. On a rural two-lane road you pass small blue signs, each naming one business with an arrow and a distance. What are they?
Show answer
Answer D: Tourist-oriented directional signs for traveler businesses
Tourist-oriented directional signs carry a white legend on blue and are used on rural conventional roads to guide travelers to eligible businesses.
-
5. A front tire blows out at highway speed. What should you do?
Show answer
Answer B: Hold the wheel firmly, ease off the accelerator and slow gradually before leaving the road
A blowout pulls the vehicle toward the failed tire, and hard braking or sharp steering can turn that pull into a spin, so a firm grip and gradual slowing keep the vehicle straight.
-
6. You have driven at 70 mph for an hour and then exit onto a town street. What is the common risk?
Show answer
Answer B: Your sense of speed adapts, so 35 mph feels slow and you drive too fast
After a long stretch at high speed the brain adapts, so town speeds feel unnaturally slow; check the speedometer instead of trusting the feeling.
-
7. The motorcyclist ahead of you keeps moving from one side of the lane to the other. What should you understand?
Show answer
Answer B: The rider is avoiding surface hazards and staying where drivers can see the bike
Riders shift their lane position to avoid debris, grease strips and potholes and to be seen. That movement is normal and never an invitation to share the lane.
-
8. You have parked a manual transmission car facing downhill. Which gear should you leave it in?
Show answer
Answer D: Reverse, along with the parking brake set firmly
Facing downhill the car would roll forward, so reverse gear opposes that movement while the parking brake and turned wheels back it up.
-
9. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?
Show answer
Answer B: Obstruction of the normal flow of traffic, which is prohibited in itself
Driving so slowly that other traffic is impeded is an offense in its own right when nothing about safety, weather or the road calls for it.
-
10. A vehicle is sitting in your blind spot and you need to change into that lane. What should you do?
Show answer
Answer B: Adjust your speed to open a clear gap, then check again and move over
Changing your speed either drops the other vehicle behind you or lets it move ahead, which turns the blind spot back into open space.
-
11. Once a driver has joined the route this sign begins, how is the rest of the way marked?
Show answer
Answer B: By further markers of the same kind at each turn, until the original road is rejoined
The alternate route is signed continuously, with a marker at every turn, so a driver with no local knowledge can follow it back to the original road.
-
12. 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.
-
13. How do extra passengers affect a driver, especially a new one?
Show answer
Answer A: They increase the chance of distraction and of crashes
Conversation, laughter and horseplay pull a driver's attention away from the road. Crash risk for young drivers rises with each additional passenger.
-
14. Your vehicle does not have antilock brakes and you must stop quickly on a slippery road. What is the correct technique?
Show answer
Answer B: Apply the brakes firmly without locking the wheels, releasing slightly if they lock
Locked wheels slide and cannot steer. Squeezing the brakes to just short of lockup, and easing off if they lock, gives the shortest stop with control.
-
15. School warning signs use which background and legend colors?
Show answer
Answer A: A black legend and border on a fluorescent yellow-green background
School warning signs carry a black legend and border on a fluorescent yellow-green background, a shade chosen so they stand out from ordinary yellow warning signs.
-
16. Your vehicle is stuck in deep snow and you run the engine for heat while waiting for help. What must you check?
Show answer
Answer C: That the exhaust pipe is clear of snow
Snow packed around the tailpipe pushes exhaust back into the cabin, and carbon monoxide can kill without warning. Clear the pipe and crack a window open.
-
17. The word SCHOOL is painted in large letters across the roadway. What is it doing?
Show answer
Answer D: Backing up the signs marking a school zone
Word markings on the pavement reinforce a message that is already signed, and a driver looking at the road ahead cannot miss them.
-
18. A city transit bus ahead of you has stopped at the curb with its passenger door open. What does the law require of you?
Show answer
Answer D: Nothing special, but pass slowly and watch for people
The mandatory stop applies to a school bus showing red flashing lights, not to a transit bus, though a careful driver still slows for crossing passengers.
-
19. How can you tell that a child safety seat is installed tightly enough?
Show answer
Answer C: It moves less than an inch side to side or front to back at the belt path
A correctly installed seat is nearly immovable where the belt or lower anchors pass through it. Excess movement lets the child's body travel farther in a crash.
-
20. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?
Show answer
Answer C: No, the shoulder is not a travel lane
Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.
-
21. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
22. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
-
23. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
-
24. Your low beams light about 250 feet of road, but at your speed you would need more than that to stop. What is that called?
Show answer
Answer D: Overdriving your headlights
When your stopping distance is longer than the stretch of road your headlights show, you cannot react to anything you finally see. Slow down until you can.
-
25. You are stopped inside an intersection waiting for a gap to turn left. How should your front wheels be positioned?
Show answer
Answer C: Pointing straight ahead until you actually begin the turn
If your wheels are already turned left and another vehicle strikes you from behind, you would be pushed into oncoming traffic.
