Am I Ready for the Iowa Permit Test?
12-question diagnostic · 4 easy, 4 medium, 4 hard · Updated July 12, 2026
Twelve questions, deliberately mixed: four easy, four medium, four of the hardest in our verified Iowa bank. The real test needs 80% — but a diagnostic this short needs a margin, so read your result like this: 11+ of 12, you're ready to book; 9–10, you're close — drill the 25 hardest first; below that, work the full test ladder before test day.
Answer each question to see the explanation. Your score is tallied against the real passing bar at the end.
1. In Iowa, the official name for the offense of drunk or drugged driving is:
Show answer & explanation
Correct answer: Operating While Intoxicated (OWI)
Iowa’s offense is called “Operating While Intoxicated” (OWI). It is defined as operating a vehicle with a blood alcohol concentration (BAC) of .08 or higher, or with any amount of a controlled substance in your system.
2. In Iowa, who is required to have a permit or license?
Show answer & explanation
Correct answer: Anyone operating a motor vehicle, motorcycle, or moped on public roads
In Iowa, anyone operating a motor vehicle, motorcycle, or moped on public roads is required to have a permit or license.
3. The large blind spots around a truck or bus where the driver cannot see you are called:
Show answer & explanation
Correct answer: “No-zones”
Large trucks have blind spots — called “no-zones” — around the front, back, and sides. If you can’t see the truck driver in the truck’s mirror, the driver can’t see you.
4. What must you do at a solid red traffic signal?
Show answer & explanation
Correct answer: Come to a complete stop
A solid red light means come to a complete stop and wait until the light changes and it is safe to proceed.
5. If you park next to a curb, how close to the curb must your vehicle be?
Show answer & explanation
Correct answer: Within 18 inches of the curb or closer
If you must park on a roadway with a curb, park within 18 inches of the curb or closer so your vehicle does not become a hazard to traffic.
6. What is the #1 cause of traffic-related fatalities in Iowa?
Show answer & explanation
Correct answer: Failure to yield the right-of-way
Failure to yield the right-of-way is the number one cause of traffic-related fatalities in Iowa. The law says who must yield; it does not give anyone the right-of-way.
7. How can you check whether your tire tread is still safe?
Show answer & explanation
Correct answer: Insert a penny head-first into the tread; if the tread does not reach the top of Lincoln’s head, the tire is unsafe
Stick a penny into the tread “head” first. If the tread does not reach at least the top of Lincoln’s head, the tire is unsafe and should be replaced. Worn tires increase stopping distance and can cause hydroplaning.
8. Which of the following makes you an Iowa resident for driver-licensing purposes?
Show answer & explanation
Correct answer: Living in Iowa continuously for 30 days
You are considered an Iowa resident for licensing purposes if you do any one of several things — including living in Iowa continuously for 30 days, registering to vote here, enrolling your child in an Iowa public school, or accepting a permanent job in Iowa.
9. Truck drivers sometimes swing wide to the left before making a right turn. You should:
Show answer & explanation
Correct answer: Not cut in between the truck and the curb
Truck drivers sometimes swing widely left to negotiate a right turn and can’t see cars directly behind or beside them. Cutting in between the truck and the curb increases the chance of a crash — give them room.
10. 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.
11. 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.
12. How close to a fire station entrance may you park?
Show answer & explanation
Correct answer: No closer than 20 feet from the entrance
Do not park closer than 20 feet from a fire station entrance, so emergency vehicles can enter and exit freely.
