1. Cannabis is legal for adults in some states. What does that mean for driving?
Show answer
Answer C: Driving while impaired by it is still an offense
Legal possession has nothing to do with driving law, and every state treats driving while impaired by cannabis as an offense.
-
2. Which feature matters most in clothing meant to keep a rider warm?
Show answer
Answer C: A windproof outer layer, since moving air strips body heat fast
Wind blowing through clothing carries away heat faster than anything else, so a windproof outer shell over insulating layers is what keeps a rider warm.
-
3. You are traveling at the same speed as a vehicle in the next lane, just behind its rear door. What should you do?
Show answer
Answer B: Change your speed so that you leave that driver's blind spot
That position is the classic blind spot. Slow slightly or move ahead so the other driver can see you before deciding to change lanes.
-
4. On a street with parking along the curb, the shared lane marking is painted well out from the curb face. What does that placement tell a bicyclist?
Show answer
Answer C: To ride clear of the doors of parked cars
The marking is set at least eleven feet from the curb where parking is allowed so that riders are guided outside the reach of an opening door.
-
5. You are waiting to turn left across two oncoming lanes when a driver in the near lane stops and waves you through. What should you do?
Show answer
Answer D: Turn only after checking the far lane yourself
The waving driver cannot give away the right of way of the traffic in the second lane, which may not be stopping at all.
-
6. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
7. On a rainy road, where can a rider usually find the best traction?
Show answer
Answer A: In the tire tracks left by the vehicles ahead
Vehicles ahead push water aside and keep their tracks clearer of oil, so those tracks generally give better grip than the rest of the lane.
-
8. What must a driver be prepared to do at the point this sign refers to?
Show answer
Answer D: Turn left or right, because the road being traveled ends there
The road ends at another roadway, so the driver must slow, give way to traffic on the through road and turn in one direction or the other.
-
9. A deer has just crossed in front of you on a stretch signed for animal crossings. What is the best assumption?
Show answer
Answer B: More animals are likely to follow the first one
Deer travel in groups, so one animal crossing usually means others are about to follow, and a driver should slow and keep scanning both shoulders.
-
10. The lane control signal above your lane changes to a steady yellow X. What should you do?
Show answer
Answer A: Prepare to leave the lane, because it is about to be closed
A steady yellow X is the warning that the lane below it is about to close, giving drivers time to move over before the red X appears.
-
11. Lights set into the pavement along both edges of a crosswalk start to flash yellow as you approach. What do they tell you?
Show answer
Answer D: Someone is crossing and has to be given way
In-roadway warning lights flash only when a pedestrian activates the crossing, so a flashing pattern means somebody is in or entering the crosswalk.
-
12. A raised area crosses the roadway and carries a series of white markings on its face. What are those markings for?
Show answer
Answer A: To make the hump visible so drivers slow for it
Speed hump markings warn drivers that the pavement rises, which matters most at night or when the hump is in shadow.
-
13. What does Iowa law say about riding a motorcycle between lanes of traffic?
Show answer
Answer C: It is prohibited on Iowa highways
Iowa Code section 321.275 states that a motorcycle or motorized bicycle shall not be operated between lanes of traffic or between adjacent lines or rows of vehicles.
-
14. 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.
-
15. What fine does Iowa assess for a first operating while intoxicated conviction?
Show answer
Answer A: One thousand two hundred fifty dollars
Iowa Code section 321J.2 sets the first-offense fine at one thousand two hundred fifty dollars, part of which the court may waive if no injury resulted and the defendant obtains a temporary restricted license.
-
16. On a hot summer day you notice long black strips of crack sealant snaking across the pavement. What should a rider know about them?
Show answer
Answer A: They soften in heat and can be slippery, especially under a leaned tire
Crack sealant gets soft and greasy in the heat, so treat those strips as a low traction surface and avoid braking or hard cornering on them.
-
17. What should you do as you approach your exit from a roundabout?
Show answer
Answer A: Signal right and check the crosswalk for pedestrians before leaving
A right signal tells following drivers and waiting drivers that you are leaving, and pedestrians cross at the exit leg, so the crosswalk must be checked.
-
18. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
19. A black and white regulatory sign facing traffic at a divided section reads KEEP LEFT. What does it require?
Show answer
Answer D: Passing the island or obstruction on its left side
Keep Left is posted at an island or obstruction that traffic must pass on the left, which is the opposite of the far more common Keep Right situation.
-
20. A group has just stopped at a stop sign. How should the formation be restored?
Show answer
Answer B: Riders should pull away one at a time and take up the stagger once moving
Motorcycles need room to pull away and get up to speed, so the staggered formation is taken up again only after the riders are rolling.
-
21. You are starting from a stop on a snowy, icy street and the drive wheels begin to spin. What should you do?
Show answer
Answer C: Ease off the accelerator and start again more gently
Spinning tires polish the surface and dig in. Very gentle pressure on the accelerator, and a higher gear if you have one, gives the tires the best chance to grip.
-
22. When should a passenger get on the motorcycle?
Show answer
Answer D: After the engine has been started and the operator is ready
Mounting after the engine is running and the operator is settled keeps the motorcycle stable and spares the operator a long balancing act with the extra weight aboard.
-
23. How can you tell a tire has reached its wear limit without measuring it?
Show answer
Answer C: The wear bars across the grooves become level with the tread
Molded bars sit at the bottom of the grooves. Once the surrounding tread has worn down to them, the tire has reached the end of its safe life.
-
24. What does a steady yellow traffic light tell the driver facing it?
Show answer
Answer A: The green movement is ending and a red indication is about to appear
A steady yellow warns that the related green movement is being terminated and that red will follow, so you should stop if you can do so safely.
-
25. You are in a minor collision on a busy road. No one is hurt and both vehicles can be driven. What is the recommended thing to do?
Show answer
Answer C: Move the vehicles out of the travel lanes to a safe spot before exchanging information
Vehicles left in traffic after a minor crash invite a second, often worse, collision. Clearing the lane protects everyone, and you still exchange details and report as required.
