1. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
2. Halfway through a curve you realize you are going too fast. What is the best response?
Show answer
Answer C: Ease off the gas gently and look where you want to go
Easing off transfers a little weight to the front tires without upsetting the balance, and looking through the curve keeps your steering smooth.
-
3. The word SCHOOL is painted in large letters across the roadway. What is it doing?
Show answer
Answer D: Backing up the signs marking a school zone
Word markings on the pavement reinforce a message that is already signed, and a driver looking at the road ahead cannot miss them.
-
4. Fog thickens until you can barely make out the vehicle ahead. What is the safest action?
Show answer
Answer A: Slow right down and, if needed, leave the road at a safe place
In heavy fog the only safe speed may be very low, and if it drops below what the road allows, the answer is to pull well clear of the traffic lanes.
-
5. What is the function of a regulatory sign?
Show answer
Answer A: To inform road users of traffic laws or regulations that apply at that location
Regulatory signs state requirements that carry the force of law where they are posted, so disregarding one is a violation rather than a lapse of judgment.
-
6. A farm implement ahead of you on a two-lane road is wider than its own lane. What should you do?
Show answer
Answer D: Hang back until you can see past it and pass only with a clear road
Wide equipment hides the road ahead and may extend farther across the center line than it appears, so the pass needs more room and a much better view.
-
7. What is the correct order of steps as you finish parking an automatic on a grade?
Show answer
Answer C: Turn the wheels, set the parking brake, then select park
Setting the parking brake before shifting into park lets the brake take the load, instead of leaving the whole weight of the car on the parking pawl.
-
8. Two roads come together at a shallow angle under a MERGE sign, with no yield line on either one. What is expected of you?
Show answer
Answer D: Adjust your speed and position so you blend smoothly into the other traffic
A merge means neither road ends at a stop; drivers adjust speed and position so that the two streams fit together without stopping.
-
9. The crossbuck, formed by two rectangular arms crossed in an X, is placed
Show answer
Answer D: on each highway approach to a railroad grade crossing
The crossbuck marks the location of a highway-rail grade crossing and is required on each highway approach to that crossing.
-
10. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
11. Your left-turn lane faces a steady green ball and oncoming traffic is heavy. What are you allowed to do?
Show answer
Answer C: Move into the intersection and turn when a safe gap appears
A green ball permits the turn but gives no priority, so you may move into the intersection and wait there for a gap in the oncoming traffic.
-
12. On a school speed limit sign, the part carrying the word SCHOOL is shown
Show answer
Answer A: in black on a fluorescent yellow-green background
The SCHOOL portion of the school speed limit sign uses the same fluorescent yellow-green background as school warning signs, while the speed portion keeps the standard regulatory appearance.
-
13. Some states allow a left turn against a red light. Which movement is it?
Show answer
Answer A: A left turn from a one-way street onto another one-way street
The movement generally allowed on red is one-way to one-way, because the turn does not cross any lane of oncoming traffic; a few states also extend it to a two-way street turning onto a one-way street.
-
14. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
15. You are leaving a freeway at an exit that has a deceleration lane. Where should you slow down?
Show answer
Answer C: After you have moved fully into the exit lane
Braking in a through lane surprises the traffic behind you, so you move into the exit lane at highway speed and then slow down inside it.
-
16. An orange sign showing the symbol of a person holding a flag or a sign paddle means that
Show answer
Answer D: a person is controlling traffic ahead and the driver must obey that person
The flagger sign warns that a trained flagger is directing traffic further on, and the flagger's instructions govern movement through the work zone.
-
17. What is the minimum period of confinement for a second Iowa operating while intoxicated conviction?
Show answer
Answer D: Seven days
Iowa Code section 321J.2 requires a minimum of seven days in the county jail or a community-based correctional facility for a second offense, up to a maximum of two years.
-
18. What happens in Iowa when a driver fails to pay a fine, surcharge, or court costs from a traffic conviction?
Show answer
Answer B: The clerk mails a notice and, if sixty days pass unpaid, the department suspends the license
Iowa Code section 321.210A has the clerk of the district court notify the person by regular mail and report the failure after sixty days, whereupon the department suspends the license until payment is made.
-
19. You find that the road surface has turned to sheet ice. What speed is appropriate?
Show answer
Answer A: A crawl, slow enough that you could stop without braking hard
Ice can cut grip to a fraction of normal, so stopping takes many times the usual distance and only a crawl leaves any margin.
-
20. A pedestrian has stepped into a crosswalk at an intersection ahead of you. What is your obligation?
Show answer
Answer C: Yield and let the pedestrian finish crossing before you proceed
Drivers must yield to pedestrians in a crosswalk, and an intersection has a legal crosswalk whether or not lines are painted on the pavement.
-
21. You reach a stop-controlled intersection at the same time as a driver on your left, but that driver is already moving through the crossing. Who goes first?
Show answer
Answer C: The driver who is already inside the intersection
A vehicle already in the intersection has the right of way, and the rule about yielding to the right applies only before anyone has entered.
-
22. Which sequence describes a well-made turn?
Show answer
Answer A: Signal, move into the correct lane, slow down, check, then turn
Tell others first, take your position, lose the speed before the corner, take a final look, and only then steer through the turn.
-
23. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?
Show answer
Answer D: Only at the openings where the solid lines are broken
The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.
-
24. A fire truck with lights and siren has just passed you and is heading down the same road. How closely may you follow it?
Show answer
Answer B: Well back, because following a responding emergency vehicle closely is illegal
Following a responding emergency vehicle closely is prohibited; the exact minimum distance is set by each state, so stay far enough back to keep the scene and other responders clear.
-
25. What is worth carrying in the vehicle during a winter trip?
Show answer
Answer A: A blanket, a flashlight, a scraper and a small shovel
A winter kit keeps you warm and visible if you are stopped for hours, and lets you clear glass and dig the wheels out. Hot water can crack cold glass.
