1. If you operate while intoxicated, your driving privileges will be revoked for a minimum of how long — even without a criminal conviction?

Show answer & explanation

Correct answer: 180 days

2. Which screening or test is required of every applicant when applying for an Iowa license?

Show answer & explanation

Correct answer: A vision screening

When you apply for your license you must complete a vision screening and pass the knowledge test. Applicants under 18 must also show they completed an Iowa-approved driver’s education course.

3. How close to a fire hydrant may you park?

Show answer & explanation

Correct answer: No closer than 5 feet from the hydrant

Do not park closer than five feet from a fire hydrant, or in a designated hydrant red zone, so firefighters can reach the hydrant in an emergency.

4. A driver entering a road from a driveway, alley, or roadside must do what?

Show answer & explanation

Correct answer: Yield to vehicles already on the main road

Drivers entering a road from a driveway, alley, or roadside must yield to vehicles already on the main road, and must also yield to pedestrians when crossing a sidewalk.

5. Even when your vehicle has advanced driver-assistance systems (ADAS), you must:

Show answer & explanation

Correct answer: Still be able to operate the vehicle yourself if the technology fails or is unavailable

ADAS features increase safety only if used correctly. Most warning systems are passive and do not prevent a crash on their own. You must still be able to operate the vehicle if the technology becomes inoperable or you drive a vehicle without it.

6. Where are car/motorcycle collisions most likely to occur?

Show answer & explanation

Correct answer: At intersections

Intersections are the most likely places for car/motorcycle collisions. Make sure you see the motorcycle and know its speed before you start to turn or enter an intersection.

7. A solid green light means you may go, but only under what condition?

Show answer & explanation

Correct answer: When the intersection is clear and you have yielded to vehicles and pedestrians in it

A solid green light means go, but only when the intersection is clear. Yield to vehicles and pedestrians already in the intersection, and give trapped traffic time to clear.

8. What do blue traffic signs mark?

Show answer & explanation

Correct answer: Services for travelers, such as rest areas, hospitals, fuel, and lodging

Blue signs direct you to services for travelers such as rest areas, tourist sites, hospitals, lodging, fuel stations, and restaurants.

9. How can you use your brake lights to communicate with a driver following too closely?

Show answer & explanation

Correct answer: Tap the brake pedal three or four times quickly to signal you are about to slow down

If you are going to slow down where another driver does not expect it, or the vehicle behind you is following too closely, tap your brake pedal three or four times quickly to let them know you are about to slow down.

10. If the speed limit is 45 mph or less, Iowa law requires you to signal at least how far before you turn?

Show answer & explanation

Correct answer: 100 feet

Iowa law requires you to signal at least 100 feet before a turn when the speed limit is 45 mph or less. Where the limit is faster than 45 mph, you must signal at least 300 feet before turning.

11. What happens with repeat OWI offenses in Iowa?

Show answer & explanation

Correct answer: They are increasingly severe, with longer license revocations and harsher criminal penalties

Repeat offenses for operating while intoxicated are increasingly severe, resulting in longer driver’s license revocations and harsher criminal penalties.

12. Under what condition is the behind-the-wheel driving test NOT required?

Show answer & explanation

Correct answer: When you satisfy the Iowa-approved driver’s education course requirement

A driving test is not required if you satisfy the driver’s education course requirement. Applicants who complete an approved course generally are not given a DOT drive test.

13. How close to a stop sign are you allowed to park?

Show answer & explanation

Correct answer: No closer than 10 feet from the stop sign

Do not park closer than 10 feet from a stop sign. Parking too close can block the sign from the view of other drivers.

14. At an uncontrolled intersection (no stop sign or signal) where two vehicles arrive at roughly the same time, who yields?

Show answer & explanation

Correct answer: The driver on the left yields to the driver on the right

At an uncontrolled intersection, all drivers must slow down and approach carefully. When two vehicles arrive at roughly the same time, the driver on the left must yield to the driver on the right.

15. In Iowa, not wearing a seat belt is:

Show answer & explanation

Correct answer: A primary offense — you can be stopped solely for not wearing one

Not wearing a seat belt is a primary offense in Iowa, meaning an officer can stop you for that reason alone. The violation is punishable by up to a $50 fine per passenger, and $100 per passenger under 18.

16. When driving behind a motorcycle, you should allow a following distance of at least:

Show answer & explanation

Correct answer: 3 to 4 seconds

Allow at least a 3- to 4-second following distance behind a motorcycle. This gives the rider room to maneuver or stop in an emergency; stay even further back when the road is wet or slippery.

17. What does a flashing yellow arrow signal mean?

Show answer & explanation

Correct answer: Yield to oncoming traffic and pedestrians, then turn proceeding with caution

A flashing yellow arrow means yield to oncoming traffic and pedestrians, then turn while proceeding with caution — oncoming traffic has a green light.

18. A fluorescent yellow-green sign is used for what type of warning?

Show answer & explanation

Correct answer: Pedestrian, bicycle, and school warning signs

Fluorescent yellow-green is used for pedestrian, bicycle, and school warning signs — its bright color draws extra attention to vulnerable road users.

19. How does higher speed affect the distance needed to stop?

Show answer & explanation

Correct answer: At higher speeds it takes longer to stop

At higher speeds it takes longer to stop. The faster your vehicle is going, the more distance it takes to turn, slow, or stop.

20. On a road where the speed limit is faster than 45 mph, you must signal at least how far before you turn?

Show answer & explanation

Correct answer: 300 feet

When the speed limit is faster than 45 mph, Iowa law requires you to signal at least 300 feet before you turn. At 45 mph or less the requirement is at least 100 feet.
