1. What does a NARROW BRIDGE warning sign tell a driver?
Show answer
Answer A: The bridge is tighter than the road leading up to it
A narrow bridge still carries both directions, but with much less clearance than the approaches, so drivers should slow and hold their lane position carefully.
-
2. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
3. You reach an intersection with no signs, signals or markings clearly before a vehicle that is approaching on your right. What is the rule?
Show answer
Answer B: You may go first because you got there first
At an uncontrolled intersection the first driver to arrive goes first; the yield to the right rule only settles a tie.
-
4. You are turning onto a street that has two lanes going your way. Which lane should you enter?
Show answer
Answer B: The lane closest to you, changing lanes later if you need to
Turn into the nearest lane going your direction and make any lane change afterwards, when you have signaled and checked that it is clear.
-
5. You are on an entrance ramp merging onto a freeway. Who has to give way?
Show answer
Answer B: You must yield and fit into a gap in the traffic already on the freeway
Traffic entering a highway must yield to traffic already on it. Use the acceleration lane to match speed and merge into a gap.
-
6. You are waiting to enter a two-lane roundabout and traffic is circulating in both lanes. What must you do?
Show answer
Answer A: Yield to traffic in both circulating lanes before you enter
Every entry to a roundabout is a yield point, and at a two-lane roundabout that means giving way to vehicles in either circulating lane.
-
7. Why should pant legs be secured and bootlaces tucked away?
Show answer
Answer A: Loose fabric and laces can tangle in the chain, the controls or a wheel
Anything hanging near the moving parts of a motorcycle can be caught and pulled in, which can trap a foot or lock the rear wheel.
-
8. Your light is green but the traffic beyond the intersection is stopped and there is no room on the far side. What should you do?
Show answer
Answer A: Wait behind the line until you can clear the far side
Entering an intersection you cannot clear blocks the cross traffic when their signal turns green, so you wait behind the line.
-
9. Rain has been falling steadily for half an hour. How does traction compare with the first minutes of the shower?
Show answer
Answer C: It usually improves somewhat, because the early oil film has washed away
Rain floats oil and dust to the top at first, so the road is most slippery in the early minutes, and a longer downpour rinses much of that film away. The pavement is still wet and grips less than when it is dry.
-
10. Why is a motorcycle particularly hard for other drivers to judge at night?
Show answer
Answer A: Its single headlight gives no width cues for distance and speed
Drivers judge distance from the spacing between a pair of headlights, and a single lamp gives them nothing to measure, so they routinely misjudge how close and how fast a motorcycle is.
-
11. Which federal standard must a motorcycle helmet meet to be sold for on-road use in the United States?
Show answer
Answer B: FMVSS No. 218
Federal Motor Vehicle Safety Standard No. 218 sets the impact, penetration and retention requirements for motorcycle helmets sold in the United States.
-
12. On a motorcycle with a standard shift pattern, where is neutral found?
Show answer
Answer C: Between first gear and second gear
The usual pattern is one down and the rest up, with neutral sitting half a click between first and second gear.
-
13. You stop behind another vehicle at a traffic light. How much space should you leave?
Show answer
Answer D: Enough to see where its rear tires touch the pavement
Seeing the rear tires on the road leaves room to steer around the vehicle if it stalls, and gives a cushion if you are struck from behind.
-
14. For how long may an Iowa motorcycle instruction permit be issued, and can it be renewed?
Show answer
Answer C: Up to four years from the birthday anniversary in the year of issuance, and it is not renewable
Iowa Code section 321.180B makes an instruction permit valid for a period not to exceed four years from the licensee's birthday anniversary in the year of issuance and states that a motorcycle instruction permit issued under that section is not renewable.
-
15. A line beside your lane is painted about twice the normal width. What does the extra width convey?
Show answer
Answer B: Greater emphasis on the restriction it carries
Width is part of the marking code: a wide line carries more emphasis than a normal one, which is why it is used at gores and channelizing lines.
-
16. Two left-turn lanes are marked at the intersection and you are in the left one. What must you do?
Show answer
Answer A: Stay in your own lane all the way around the turn
With dual turn lanes each driver must hold a lane through the whole turn and come out in the matching lane of the new street.
-
17. You are parking on a one-way street where parking is allowed on both sides. What must still be true?
Show answer
Answer D: The vehicle must face the direction the traffic flows
Either curb may be used on a one-way street where signs allow it, but the vehicle must always be headed in the direction traffic moves.
-
18. 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.
-
19. Where should the hooks of an elastic luggage cord be attached?
Show answer
Answer D: To solid points on the frame or the rack that will take the pull
Hooking a cord to bodywork, a signal stalk or a cable can break the part or damage the wiring, and the load is loose the moment the anchor fails.
-
20. 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.
-
21. How should a rider approach a curve whose radius keeps tightening the further you go into it?
Show answer
Answer A: Enter more slowly than the curve first appears to need, saving lean for the exit
In a decreasing radius curve the sharpest part comes last, so a slower entry leaves both speed and lean angle in reserve for where they are needed.
-
22. When are the hazard warning lights properly used?
Show answer
Answer A: When your vehicle is stopped or barely moving and is a hazard
Hazard lights warn that your vehicle is an obstruction; they do not authorize illegal parking and they hide your turn signals while driving.
-
23. Blue pavement markings are used together with white markings at
Show answer
Answer D: parking spaces reserved for people with disabilities
Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.
-
24. A vehicle in front of you has already begun turning left into a driveway when the gap you were waiting for opens up. What should you do?
Show answer
Answer B: Wait and let that driver finish the turn
A vehicle that has lawfully started a maneuver keeps the right of way until it is finished.
-
25. How much following distance should you keep behind a motorcycle?
Show answer
Answer C: At least three to four seconds
A motorcycle can slow or stop very quickly and is easily upset by a surprise, so allow three to four seconds instead of the usual car gap.
