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
Even if you are not convicted of OWI in criminal court, your driving privileges will still be revoked for a minimum of 180 days if you operate while intoxicated.
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.
