1. How does becoming chilled affect a rider before any shivering is obvious?
Show answer
Answer D: It slows reactions and clouds judgment while the rider still feels fine
Cooling degrades reaction time and decision making before the rider notices it, so dress for the coldest part of the ride and stop to warm up rather than pressing on.
-
2. A large truck passes and hits you with a blast of wind. Which lane position leaves you the most room for error?
Show answer
Answer A: The center portion of the lane
A rider in the center portion of the lane has space on both sides to absorb the push of a wind blast without being shoved out of the lane.
-
3. You have tied a load down with cords that are longer than you need. What should you do with the loose ends?
Show answer
Answer D: Secure the loose ends so nothing can reach the chain, the wheel or the road
A dangling cord can be caught by the rear wheel or the chain and jam it, which can lock the wheel without any warning to the rider.
-
4. A car is coming straight at you in your lane and there is no time for it to move back. What should you do?
Show answer
Answer A: Brake, sound the horn and steer to the right, toward the shoulder or ditch
Steering right takes you away from the other vehicle even if its driver corrects course, and the shoulder or ditch is survivable.
-
5. What does black ice usually look like from the driver seat?
Show answer
Answer C: A patch of pavement that simply looks wet or slightly glossy
Black ice is clear, so you see the dark road through it and read it as a wet patch. In freezing weather, treat any wet looking patch as ice.
-
6. How does a rider open the throttle to increase speed?
Show answer
Answer C: By rolling the right handgrip toward the rider
Rolling the right handgrip toward you opens the throttle, and rolling it away closes it so the engine slows.
-
7. The left-turn signal facing you shows a flashing yellow arrow. What does it mean?
Show answer
Answer C: You may turn left after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow permits a left turn but gives no protection, so you must yield to oncoming vehicles and to people in the crosswalk.
-
8. Where does the restriction that starts at this sign come to an end?
Show answer
Answer D: Where the centerline markings show that overtaking is allowed again
The sign marks the start of the restricted section, and the centerline markings along the road show how far it runs and where overtaking becomes lawful again.
-
9. A NO LEFT TURN sign carries a plaque reading 7 AM TO 9 AM MON TO FRI. What does the assembly mean?
Show answer
Answer A: The turn is banned only during those hours on those days
A time plaque limits the restriction to the periods shown, so outside those hours and days the left turn may be made normally.
-
10. A school crossing guard steps into the roadway and holds up a stop paddle. What must you do?
Show answer
Answer D: Stop and stay stopped until the guard and the children have left the road
A crossing guard directs traffic with legal authority; you must remain stopped until both the guard and the children are clear of the roadway.
-
11. You are wearing a high visibility jacket. How should that change the way you ride?
Show answer
Answer B: You still ride as though drivers have not seen you
Bright gear improves your odds of being noticed but guarantees nothing, so keep the lane position, space cushion and escape routes that protect you anyway.
-
12. Traffic is backed up just past the exit you want to use at a single-lane roundabout. What should you do?
Show answer
Answer D: Wait at the yield line until you can pass through and exit
You must not enter a roundabout unless you can clear it, because stopping inside blocks every other entry.
-
13. Where is reflective material most effective at attracting a driver's attention at night?
Show answer
Answer A: On the arms, legs and helmet, where the movement draws the eye
Reflective patches that move as the rider rides are noticed sooner than static ones, and a helmet sits high where drivers are already looking.
-
14. You are behind three slow vehicles on a two-lane road and the way ahead looks clear. What is the sound decision?
Show answer
Answer D: Pass one vehicle at a time, if the road allows it
Passing several vehicles in one move keeps you in the oncoming lane far too long and leaves nowhere to go if a vehicle appears.
-
15. A yellow diamond shows a horse with a rider. Besides slowing down, what else should a driver do?
Show answer
Answer C: Avoid using the horn or revving the engine
The equestrian crossing sign warns of horses on or across the road, and a sudden noise can startle an animal into the traffic lane.
-
16. What does the Iowa electronic device statute say the word use includes?
Show answer
Answer C: Holding, viewing, or manipulating the device
Iowa Code section 321.276 defines use to include holding, viewing, or manipulating an electronic device, which is why simply having it in the hand can be a violation.
-
17. How should a passenger swing their leg when getting off the motorcycle?
Show answer
Answer D: High and clear of the exhaust and the rear of the machine
A leg dragged low across the back of the motorcycle can catch the seat or the luggage and will find the hot exhaust, so it is lifted well clear.
-
18. A driver in the left lane of a freeway realizes only when level with this sign that the ramp beside it is the one they need. What is the correct action?
Show answer
Answer A: Carry on to the next interchange and turn back from there
There is no safe way back to a ramp once it has been reached from the wrong lane, so the driver keeps going to the next interchange, where the ramps are built for that movement.
-
19. The crossing gates begin to lower while your vehicle is still on the railroad tracks. What should you do?
Show answer
Answer B: Keep going forward and push through the gate if it should block your way
Gates are made to break away, and driving forward off the tracks is far safer than staying between them or backing up.
-
20. A yellow diamond shows an arrow bent into a series of reversing turns. What does it warn about?
Show answer
Answer A: Three or more changes of direction close together
The winding road sign replaces a string of separate curve signs where several bends follow one another with only short straights between them.
-
21. Once a driver has joined the route this sign begins, how is the rest of the way marked?
Show answer
Answer B: By further markers of the same kind at each turn, until the original road is rejoined
The alternate route is signed continuously, with a marker at every turn, so a driver with no local knowledge can follow it back to the original road.
-
22. The curb ahead is signed as a bus stop. May you wait there with your vehicle?
Show answer
Answer C: No, the space must stay clear for buses
A bus stop must stay open so that a bus can reach the curb and let passengers on and off safely, so no other vehicle may occupy it.
-
23. You are driving on an open highway in a strong crosswind. What is the safest adjustment?
Show answer
Answer A: Reduce speed and keep a firm grip, expecting gusts on bridges and beside large vehicles
Gusts hit hardest in open gaps, on bridges and when passing high-sided vehicles, so a lower speed and a firm grip let you correct before you are pushed out of your lane.
-
24. You are stopped at a red light waiting to turn right where the turn is allowed. Besides traffic from the left, what must you check?
Show answer
Answer D: Both crosswalks, and anyone approaching along your right side
A right turn on red crosses the crosswalk in front of you and enters the one on the cross street, and cyclists often approach along your right.
-
25. In a work zone, the flagger's instructions conflict with the pavement markings still visible on the road. Which do you follow?
Show answer
Answer B: The flagger, because a person directing traffic outranks the markings
An authorized flagger controlling a temporary traffic control zone overrides signs, signals and markings, and drivers must obey the flagger's signals.
