Iowa Permit Practice Test 2
A second full-length Iowa practice test: 30 fresh multiple-choice questions with zero repeats from Test 1. You need 80% correct to pass the real Iowa DOT Knowledge Test.
Question 1 of 30
1. Under Iowa's school bus law, known as Kadyn's Law, what penalty can a first conviction for illegally passing a stopped school bus bring?
Show answer & explanation
Correct answer: A. Iowa Code 321.372, the Keep Aware Driving — Youth Need School Safety Act, makes a first offense a simple misdemeanor: $345 to $930 in fines, up to 30 days in jail, or both. A second offense becomes a serious misdemeanor.
2. You finished driver education and have held your Iowa instruction permit with a clean record for six straight months. At what age can you apply for the special minor's restricted license to drive yourself to school?
Show answer & explanation
Correct answer: B. Iowa's special minor's restricted license, often called the school license, opens at 14 1/2 for students meeting driver-ed and clean-permit requirements. It allows unsupervised trips to school by the most direct route. Hook: half a year past fourteen.
3. Your headlights suddenly go dark while you are driving at night. What should you do first?
Show answer & explanation
Correct answer: C. First flick the headlight switch and dimmer, since the problem may be a loose connection; then use parking, hazard, or turn lights to stay visible while you leave the road. Never keep driving blind hoping the lights return.
4. In a work zone, an orange sign warns of a flagger ahead. The flagger signals you to stop, even though the traffic light beyond is green. What should you do?
Show answer & explanation
Correct answer: C. Flaggers control traffic through work zones, and you must obey their directions even when they conflict with posted signs or signals. They can see hazards you cannot. Remember: in a work zone, the person outranks the light.
5. What happens when a car hydroplanes on a wet road?
Show answer & explanation
Correct answer: C. Hydroplaning happens when tires ride up on a layer of water instead of the pavement, erasing steering and braking grip. Higher speeds make it far more likely. Ease off the gas smoothly; think of tires turning into water skis.
6. Before Iowa issues you a full driver's license at 17, how much supervised driving must be certified from your time at the intermediate stage?
Show answer & explanation
Correct answer: C. Iowa's final graduated step requires 12 consecutive intermediate months plus 10 more supervised hours, 2 of them after dark. Coached practice continues even after you drive alone. Remember the ladder: 20 hours before 16, 10 before 17.
7. You are passing a slow truck on a Iowa highway posted at the state's maximum limit. Even while passing, your legal ceiling stays at which speed?
Show answer & explanation
Correct answer: B. Passing grants zero extra speed allowance; in Iowa the ceiling on those top-posted highways stays 70 mph. If you cannot complete the pass within the limit, wait for a better gap. The limit binds every maneuver, always.
8. Besides nighttime, when should you turn on your headlights?
Show answer & explanation
Correct answer: D. Turn on your headlights whenever conditions cut visibility, including rain, fog, snow, dusk, or dawn, because lights help other drivers spot you as much as they help you see. Handy habit: wipers on or gray sky means lights on.
9. Under Iowa's implied consent law, what does refusing a chemical test after a lawful OWI arrest trigger, even for a first refusal?
Show answer & explanation
Correct answer: D. Holding an Iowa license means you have already agreed to sobriety testing under Iowa Code 321J.6. Refusal brings an automatic one-year revocation plus a minimum $1,250 fine, harsher than failing the test. Refusing costs more, not less.
10. An 18-year-old in Iowa 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 0.02%, the level where Iowa'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.
11. The signal shows a green arrow for your left turn. What does having a 'protected' turn mean?
Show answer & explanation
Correct answer: B. A green arrow gives you a protected turn: conflicting traffic is held by a red signal. Still glance for people or vehicles already in the intersection, because protected means favored, not guaranteed safe.
12. The light is steady green as you reach an intersection. Which statement is true?
Show answer & explanation
Correct answer: B. A green light means you may proceed, but only after yielding to pedestrians and vehicles still clearing the intersection. Green grants permission, not protection, so look left, right, and left again before you enter.
13. On a highway, you look for the way to your destination city. What kind of information do signs with a green background give you?
Show answer & explanation
Correct answer: D. Green guide signs point the way, listing destinations, how many miles remain, and which exits to take. They inform rather than command, so no action is required. Think of green as the color that says go this way.
14. You approach an intersection with no signs or signals, and another vehicle approaches from a cross street at about the same time. Who should yield?
Show answer & explanation
Correct answer: A. At an uncontrolled intersection, slow down and yield to any vehicle that reaches it at about the same time from your right. Without signs, this default rule sorts out conflicts. Same tiebreaker as a four-way stop: right goes first.
15. In freezing weather, why do bridges and overpasses ice over before the roads around them?
Show answer & explanation
Correct answer: C. A bridge has cold air on top and underneath, while ordinary pavement is warmed by the ground below, so bridges freeze first. Slow down before crossing one in cold weather and avoid sudden braking or steering there.
16. On a highway you pass a white regulatory sign reading MINIMUM SPEED 40. Why is that sign posted?
Show answer & explanation
Correct answer: D. A minimum speed sign requires you to travel at least the posted speed when conditions allow. Highways post it because vehicles moving far below the flow cause rear-end and lane-change crashes. Too slow can be as dangerous as too fast.
17. You are studying for the Iowa permit knowledge exam and want to schedule it as early as the law allows. You can hold a learner's permit beginning at which age?
Show answer & explanation
Correct answer: C. In Iowa, 14 is the earliest age for a learner's permit, so plan your knowledge exam around that date. Study the official handbook, since permit questions come from it, and arrive with the required documents ready.
18. Under Iowa's zero-tolerance law, what BAC level counts as a violation for a driver under 21?
Show answer & explanation
Correct answer: B. Iowa's zero-tolerance law sets the under-21 threshold at 0.02%, far stricter than the adult standard. Underage drinking is illegal to begin with, so the safest and simplest rule is zero alcohol before driving, always.
19. Children are playing near the curb on an unposted neighborhood street in Iowa. Unless a sign says otherwise, the fastest you may legally drive here is which speed?
Show answer & explanation
Correct answer: A. The default residential limit in Iowa is 25 mph unless otherwise posted. With children nearby, you should often go slower still, because stopping distance grows quickly with speed and kids can dart into the street without warning.
20. Under zero-tolerance laws, what happens to a driver under 21 caught with any measurable alcohol in their system?
Show answer & explanation
Correct answer: A. Every state enforces zero tolerance: drivers under 21 face penalties, typically license loss, for any measurable amount of alcohol. Because underage drinking is illegal, no level is acceptable. For young drivers, the only safe number is zero.
21. Which parking spot is illegal no matter how briefly you plan to stay?
Show answer & explanation
Correct answer: D. Parking within the cleared space around a fire hydrant is always illegal, because firefighters may need instant access to connect hoses. Blocking a hydrant can cost lives during a fire. If you see a hydrant, leave the whole area open.
22. You are lawfully arrested for impaired driving and refuse the chemical test. What should you expect?
Show answer & explanation
Correct answer: C. Refusing the test triggers its own penalty: license suspension under implied-consent laws, separate from any court case. Refusal does not make the problem disappear. Remember, saying no to the test means saying goodbye to your license.
23. When you finish parallel parking, how should your car be positioned?
Show answer & explanation
Correct answer: A. End a parallel park close to the curb and parallel with it, so your vehicle does not poke into the traffic lane. A car sticking out invites sideswipes and mirror strikes. Tuck in tight; the lane belongs to traffic.
24. Setting cruise control on a rural Iowa interstate posted at the state maximum, you should set it no higher than which speed?
Show answer & explanation
Correct answer: B. The state maximum in Iowa is 70 mph, so cruise control should never be set above it where that limit is posted. Think of the posted limit as a ceiling for ideal conditions, never a required speed.
25. You see a red-and-white triangular sign reading YIELD as you approach a traffic circle. What should you do?
Show answer & explanation
Correct answer: B. A yield sign tells you to slow down, check for traffic with the right-of-way, and stop only when necessary to let it pass. It keeps merges smooth without forcing pointless stops. Think of yield as give way, not always stop.
26. In Iowa, supervised behind-the-wheel practice with a permit can begin once a teen reaches which age?
Show answer & explanation
Correct answer: C. Supervised practice starts at 14 in Iowa, once the teen holds a learner's permit. Every practice hour with a licensed adult builds judgment that classroom study alone can never teach, which is why the permit stage exists.
27. You are low on fuel on a long highway drive. Signs of which color point you to services such as gas, food, lodging, and hospitals?
Show answer & explanation
Correct answer: B. Blue signs mark motorist services, including fuel, food, lodging, rest areas, and hospitals. They let travelers plan a stop before leaving the highway. When your body or your car needs something, look for blue.
28. In Iowa, a driver who is 21 or older commits a per-se drunk-driving offense once their blood alcohol concentration reaches which level?
Show answer & explanation
Correct answer: B. 'Per se' means the number alone proves the offense. In Iowa, that number is 0.08%. No other proof of bad driving is needed at that level, and alcohol can still impair you below it.
29. How does the alcohol in a regular beer compare with a standard glass of wine or a single shot of liquor?
Show answer & explanation
Correct answer: B. A standard beer, glass of wine, and shot of liquor each deliver about the same alcohol, so switching drinks does not protect you. Your body counts drinks, not drink types. One is one, whatever the glass looks like.
30. An emergency vehicle is stopped on the shoulder ahead with lights flashing. What do move-over laws require?
Show answer & explanation
Correct answer: D. Every state has a move-over law: shift a lane away from stopped emergency or service vehicles with flashing lights, or slow well down when changing lanes is unsafe. Roadside workers stand inches from traffic; give them that lane.
