1. A piece of farm machinery ahead of you is wider than its own lane. What should you do?
Show answer
Answer C: Hold back until you can see far enough to pass safely
Wide equipment leaves no gap inside the lane and may use part of the other side, so a pass needs a long clear view of the road ahead.
-
2. A pedestrian using a white cane or walking with a guide dog starts to cross the street ahead of you. What must you do?
Show answer
Answer A: Yield and stay stopped until the person has finished crossing
A white cane or guide dog identifies a pedestrian who may not be able to see your vehicle, so you must yield and wait rather than maneuver around the person. The horn can confuse the pedestrian or the dog.
-
3. A steady red arrow is displayed for your left-turn lane at a two-way intersection. What must you do?
Show answer
Answer C: Stop and remain stopped until an indication permits the turn
A steady red arrow prohibits the movement it points to, so the driver stops and waits for a green arrow, a flashing yellow arrow or another indication that permits the turn.
-
4. Your engine stalls while you are driving in traffic. What is the correct response?
Show answer
Answer A: Shift to neutral, try to restart it, and steer and brake toward the side of the road
With the engine off, power steering and power brake assistance fade, so steering and braking take more effort but still work. Neutral lets you attempt a restart while you coast to safety.
-
5. A yellow diamond shows two lanes narrowing into one. What does it require of a driver?
Show answer
Answer D: Adjusting speed and merging before the lane disappears
The lane ends sign gives notice that one lane will be dropped, so drivers should adjust speed and blend into the continuing lane in good time.
-
6. How long must an ignition interlock device stay installed after reinstatement following a second Iowa revocation under the intoxication chapter?
Show answer
Answer A: One year
Iowa Code section 321J.17 requires the interlock device for one year from the date of reinstatement following a second or subsequent revocation, unless a longer period is required by statute.
-
7. You have a green light and are turning right. Pedestrians are stepping off the curb into the crosswalk you are about to cross. What should you do?
Show answer
Answer B: Wait and let them cross before completing your turn
A green light does not release a turning driver from yielding to pedestrians already in the crosswalk of the street being entered.
-
8. A steady green downward arrow is displayed above the lane you are in. What does it tell you?
Show answer
Answer A: You may drive in that lane
A green downward arrow means the lane beneath it is open for travel in your direction.
-
9. You are approaching a sharp curve. When should you reduce your speed?
Show answer
Answer D: Before you enter the curve, so you can accelerate gently through it
Braking hard inside a curve uses up the traction that is already being demanded for cornering, so the slowing must be finished before you enter.
-
10. Which part of the space around your vehicle can you control best?
Show answer
Answer A: The space ahead of you
You choose your own following distance, so the gap in front is the space you truly control and the one that gives you time to react.
-
11. Why is following distance measured in seconds rather than in car lengths?
Show answer
Answer A: Because a time gap automatically grows with speed, while a fixed number of car lengths does not
A gap counted in seconds keeps the same margin of reaction time at any speed, whereas a fixed number of car lengths becomes far too small as speed rises.
-
12. What should you do about snow and ice on your vehicle before driving?
Show answer
Answer C: Clear all glass, mirrors and lights, and the roof and hood as well
Snow left on the roof or hood slides onto your windshield when you brake and blows into the path of drivers behind you, and covered lights make your vehicle hard to see.
-
13. You want to pass on a two-lane road where several people are walking on the narrow shoulder ahead. What should you consider?
Show answer
Answer D: There is no escape room if the pass goes wrong, so wait for a better place
A pass depends on having somewhere to go if it goes wrong, and a shoulder occupied by pedestrians removes that option for both vehicles.
-
14. The cars in front of and behind your parallel parked car have left you very little room. How do you get out?
Show answer
Answer D: Ease back and forth, turning the wheels each way, until you clear
Short movements with the wheels turned first one way and then the other walk the car out of a tight space without touching anything.
-
15. A loaded truck is coming up an entrance ramp as you approach in the right lane of the freeway. What is the most helpful action?
Show answer
Answer A: Adjust your speed to open a gap for it
A heavy vehicle accelerates slowly, so opening a gap or moving over costs you seconds and saves the truck driver from being forced to stop on the ramp.
-
16. Where is passing prohibited even when no line is visible?
Show answer
Answer D: On a curve or near the crest of a hill, at intersections and at railroad crossings
Passing is prohibited wherever your view of oncoming traffic is blocked or where vehicles may cross your path, which includes hills, curves, intersections and rail crossings.
-
17. A yellow horizontal rectangular sign showing one large arrow pointing left or right, facing traffic on the far side of a sharp bend, tells the driver
Show answer
Answer C: which way the roadway turns at that point
The large arrow sign is mounted on the outside of a sharp change in alignment so that a driver approaching head on immediately sees which way the road goes.
-
18. You reach a T intersection where the cross street has a ONE WAY sign pointing to the right. What may you do?
Show answer
Answer B: Turn right only, because the street carries traffic in that direction
The arrow shows the only direction traffic may travel, so the only legal movement from the terminating road is a right turn.
-
19. You find that your shoulder belt has some slack in it. Why does that matter?
Show answer
Answer D: You travel further before the belt restrains you, so injuries are worse
Slack lets your body build up speed before the belt takes hold, which increases the forces on you and the risk of hitting the interior.
-
20. A yellow diamond showing a bicycle is posted on a rural road. What should a driver expect?
Show answer
Answer A: Bicyclists crossing or riding along the roadway there
The bicycle warning sign is used where a bikeway crosses the road or where riders are likely to be in the traffic lanes, so drivers should look carefully and pass wide.
-
21. From which lane should a permitted U-turn be started?
Show answer
Answer A: The lane nearest the center line, the same one used for a left turn
A U-turn is begun from the far left lane for your direction, the same position used for a left turn, so you do not cut across traffic beside you.
-
22. Why must you never leave the engine running in a closed garage?
Show answer
Answer B: Because carbon monoxide builds up and can kill within minutes
Exhaust gas contains carbon monoxide, which has no smell or color and can reach fatal levels in an enclosed space very quickly.
-
23. What does this sign require of the driver?
Show answer
Answer D: Reducing speed and being ready to stop at the intersection ahead
The advance notice asks the driver to slow and be ready to stop, while whether a stop is actually needed depends on the indication displayed on arrival.
-
24. Under Iowa law, for how long after a license expires is a driver not considered to be driving with an invalid license?
Show answer
Answer B: 60 days
Iowa Code section 321.196 provides that a person shall not be considered to be driving with an invalid license during the sixty days following the license expiration date.
-
25. A wide crosswalk you are turning across has a refuge island in the middle. What should you assume about people standing on it?
Show answer
Answer D: They may step off the island into your path at any moment
An island is a pause in a crossing, not the end of one, so treat anyone on it as a pedestrian who is still crossing.
