Question 1 of 30
1. Your 20-year-old cousin is the designated driver tonight in New Jersey. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In New Jersey, drivers under 21 violate the zero-tolerance law once their BAC reaches 0.01%. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
2. An 18-year-old in New Jersey has one beer at a graduation party and then drives. At what BAC could this driver already be violating the zero-tolerance law?
Show answer & explanation
Correct answer: C. One beer can push a young driver to 0.01%, the level where New Jersey's zero-tolerance law kicks in. The rule protects new drivers, whose crash risk rises quickly with alcohol. Skip every drink if you plan to drive.
3. You have been driving through a no-passing zone. Which sign tells you the zone has ended and passing is allowed again when safe?
Show answer & explanation
Correct answer: D. A white regulatory sign reading PASS WITH CARE marks the end of a no-passing zone. You may pass again, but only when the road ahead is clear. The word CARE reminds you the choice is still yours to judge.
4. You are 17 and hold a New Jersey examination permit. What must be attached to any vehicle you drive?
Show answer & explanation
Correct answer: C. New Jersey's Kyleigh's Law requires GDL drivers under 21 to display a red reflectorized decal on the upper left corner of both license plates. The decals help police spot new drivers. Memory hook: two plates, two red decals.
5. You are in a left-turn lane facing oncoming traffic, and the signal shows a steady red arrow. What does the arrow mean?
Show answer & explanation
Correct answer: A. A steady red arrow prohibits the movement it points toward; you must stop and stay put until the signal changes. It shields turning drivers from crossing busy oncoming lanes. Think of a red arrow as a closed gate.
6. A teen walks into a New Jersey Motor Vehicle Commission (MVC) office in New Jersey to apply for a first learner's permit. The office can accept the application once the teen is what age?
Show answer & explanation
Correct answer: B. The MVC accepts learner's permit applications at age 16 in New Jersey. Bring proof of identity, residency, and usually a parent's signature, then pass the knowledge and vision screenings. Age is simply the first box to check.
7. A school bus with flashing red lights has stopped ahead on a two-lane New Jersey road. What must you do?
Show answer & explanation
Correct answer: B. On a two-lane New Jersey road, stop at least 25 feet from a school bus with flashing red lights; only drivers across a raised median may slow to 10 mph instead. Children dart unpredictably. Hook: red lights, 25 feet.
8. A truck ahead signals a right turn but first swings out toward the left. What should you do?
Show answer & explanation
Correct answer: C. Long vehicles swing wide to make right turns, and the tempting gap on their right closes like a trap once the trailer comes around. Hold back and wait. Do not slide into the right side of a turning truck.
9. You are driving through a residential district in New Jersey and see no speed limit signs. What is the default speed limit?
Show answer & explanation
Correct answer: C. Where no sign is posted, New Jersey's default residential limit is 25 mph. Homes mean driveways, pets, and kids near the road, so the default stays low. A posted sign overrides the default, so watch for one.
10. A school bus is stopped with red lights on the opposite side of a divided highway that has a concrete median. Must you stop?
Show answer & explanation
Correct answer: B. The median exception is the item testers and Reddit threads say people miss. A painted line is not a median. A real barrier or unpaved median means the far side typically may proceed with care. When in doubt, stop.
11. You are driving on a rural New Jersey roadway that has no posted speed limit signs. What is the maximum legal speed?
Show answer & explanation
Correct answer: B. On a rural New Jersey roadway with no posted signs, the legal maximum is 50 mph. Default limits ensure every road has an enforceable cap. Picture it: empty countryside, no signs, hold it at fifty.
12. You are on a through street. A driver on a driveway to your right is waiting to enter. Who must yield?
Show answer & explanation
Correct answer: B. Drivers leaving a driveway, alley, or parking lot yield to all traffic on the street, including bikes and people walking. The street already has the flow. Think: entering traffic waits; through traffic keeps moving unless a sign says otherwise.
13. You want to park on a street just before a crosswalk. What minimum clearance do most handbooks require?
Show answer & explanation
Correct answer: B. A common handbook rule is 20 feet from a crosswalk so turning drivers and pedestrians can see each other. Parking closer hides people in the stripes. Twenty before the walk, then the hydrant's fifteen, is the pair testers expect.
14. A quiet electric car is coming up behind a pedestrian in a parking lot. What extra care should you take?
Show answer & explanation
Correct answer: B. EVs and hybrids are hard to hear at low speed. Handbooks increasingly mention that quiet approach. In lots and on neighborhood streets, expect people to step out without looking. If they cannot hear you, you have to see for them.
15. A white sign with a green arrow and the word ONLY is mounted beside a traffic signal. When may you move in that direction?
Show answer & explanation
Correct answer: B. A signal-mounted green arrow with ONLY ties that movement to the arrow indication. Go that way when the arrow is on and the path is clear; otherwise wait. Arrows assign time as well as direction.
16. In New Jersey, what is the youngest age at which you can apply for a learner's permit?
Show answer & explanation
Correct answer: B. New Jersey issues learner's permits starting at age 16. The permit opens the first stage of graduated licensing, where you build skills with a supervising adult before earning fuller privileges. Know your state's number; it varies nationwide.
17. Only one road sign is shaped like a sideways pennant, a triangle with its point aimed to the right. Which sign is it?
Show answer & explanation
Correct answer: A. The sideways yellow pennant is used for one message only: NO PASSING ZONE. It stands on the left side of the road where passing begins to be unsafe. One shape, one meaning makes it instantly recognizable.
18. What does NHTSA say happens to alcohol after it enters the bloodstream?
Show answer & explanation
Correct answer: A. Official NHTSA drunk-driving guidance says alcohol passes into the bloodstream where it accumulates until it is metabolized by the liver. The leftover coffee-or-shower sobriety claim is not on that page; this nearby official body text is.
19. Can a small amount of alcohol affect driving, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA drunk-driving guidance says even a small amount of alcohol can affect driving ability. Even small amounts of alcohol affect one’s brain and the ability to drive. Testers invent leftover one-beer-is-nothing courtesy.
20. A 30-year-old driver in New Jersey takes a chemical test after a crash. Prosecutors can prove DUI from the test result alone once the BAC is at least which value?
Show answer & explanation
Correct answer: D. A test showing 0.08% or higher proves per-se DUI in New Jersey without any other evidence of impairment. Lawmakers chose that threshold because crash risk climbs sharply near it, though alcohol degrades driving skills at lower levels too.
21. Traffic around you on a New Jersey highway posted at the state maximum starts flowing faster than the signs allow. Your personal legal limit remains which speed?
Show answer & explanation
Correct answer: C. Other drivers speeding does not raise your limit; on New Jersey's fastest highways it stays 65 mph. Move right and let them pass instead of matching them. Speed limits bind each driver individually, whatever the surrounding traffic does.
22. In a New Jersey 65 mph zone, what happens to the fine if you are caught speeding 10 mph or more over the limit?
Show answer & explanation
Correct answer: C. Speeding 10 mph or more over the limit in a New Jersey 65 mph zone doubles your fine under N.J.S.A. 39:4-98.6; construction-zone violations double too. High-speed crashes are deadlier. Hook: push past 75, pay twice.
23. The posted limit is unchanged, but traffic, weather, and light have all gotten worse. What does the basic speed rule require?
Show answer & explanation
Correct answer: C. The basic speed rule says you may not drive faster than conditions safely allow, no matter what the sign posts. Rain, darkness, and crowds shrink your margin for error. Conditions set the real limit; the sign sets the ceiling.
24. Ahead of a raised concrete median you see a white sign reading KEEP RIGHT with an arrow curving to the right. What should you do?
Show answer & explanation
Correct answer: A. KEEP RIGHT tells you the roadway splits around an island, median, or obstruction, and all traffic must pass on the right side. Passing left would put you into oncoming lanes. Follow the arrow around the obstacle, then continue straight.
25. You are 25 and had wine at a dinner party in New Jersey. Before driving home, you check the law. At what BAC does driving become illegal for you?
Show answer & explanation
Correct answer: D. For adult drivers in New Jersey, driving is illegal at a BAC of 0.08% or above. Because impairment starts before the limit, the safest plan after drinking is a ride share, taxi, or sober designated driver.
26. If your car stalls on a railroad track, what does NHTSA say to do first?
Show answer & explanation
Correct answer: A. Official NHTSA railroad-crossing guidance says If your car stalls on a track, quickly get everyone out — even if you don’t see a train coming. Run away from the tracks and your car to avoid being hit by flying debris. Call the number on the blue emergency notification system sign.
27. A solid white line, instead of a broken one, separates your lane from the next lane going the same way. What is it telling you?
Show answer & explanation
Correct answer: A. A solid white line between same-direction lanes discourages lane changes, and it appears where drifting is risky, such as near intersections and ramps. The firmer the line looks, the firmer the message: hold your lane.
28. What is double parking, and why is it against the rules?
Show answer & explanation
Correct answer: D. Double parking means standing or parking in the roadway alongside a vehicle already parked at the curb. It blocks a travel lane, hides pedestrians, and pins in the parked car, so the practice is prohibited on public streets.
29. A traffic light is circular yellow after you have already entered the intersection on green. What should you do?
Show answer & explanation
Correct answer: B. Once you are in the intersection on green, a yellow that follows means finish the crossing smoothly. Stopping mid-box blocks others and can get you hit from behind. Yellow before the line means stop if you can; yellow after the line means clear out.
30. Until what age does NHTSA say to keep a child in the back seat?
Show answer & explanation
Correct answer: A. Official NHTSA car-seat guidance says Keep your child in the back seat at least through age 12. All children under 13 ride in the back seat for maximum safety. Rear-facing is required under age 1.
