1. At an intersection where turning on a red arrow is not permitted, the signal shows a red left arrow next to a steady green ball. What may you do?
Show answer
Answer D: Go straight or turn right if permitted, but not left
An arrow controls only the movement it points to, so here the red arrow stops the left turn while the green ball still allows the other movements.
-
2. Which ability does alcohol usually affect first?
Show answer
Answer A: Judgment and self control
Alcohol reduces judgment and inhibition before a drinker notices any clumsiness, which is why an impaired driver often feels perfectly capable while already driving worse.
-
3. Two lanes at the corner are marked for right turns. What does that require of you?
Show answer
Answer A: Keep your own lane through the turn and into the matching new lane
Dual turn lanes work only if each vehicle stays in its own lane all the way round and finishes in the corresponding lane of the new street.
-
4. Why does full riding gear matter on a short trip around the neighborhood?
Show answer
Answer D: Pavement takes skin off at 25 miles an hour just as it does at 55
Serious injuries happen at ordinary street speeds and close to home, so gear that is worth wearing on a long trip is worth wearing on a short one.
-
5. How do the traffic laws apply to riders traveling in a group?
Show answer
Answer D: Every rider is responsible for obeying the law on their own machine
Riding in company changes nothing legally, and each rider answers individually for speed, signals and every other rule of the road.
-
6. If the rear wheel locks during a straight line stop on a good surface, the rider should:
Show answer
Answer B: Keep it locked until the motorcycle has come to a complete stop
Releasing a locked rear wheel while the motorcycle is out of line can snap it upright violently, so on a straight path the rear brake is held until the motorcycle stops.
-
7. Why should baggage be kept as low as possible on a motorcycle?
Show answer
Answer C: A high load raises the center of gravity and makes the machine unstable
Weight carried high changes the balance of the motorcycle and makes it feel top heavy in turns and in crosswinds.
-
8. 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.
-
9. Two vehicles reach a four-way stop at the same moment from adjacent roads. Who should go first?
Show answer
Answer A: The driver on the right
When two drivers stop at a four-way stop at the same time, the driver on the left yields to the driver on the right.
-
10. You are the second vehicle waiting to turn left on a green ball. Where should you wait?
Show answer
Answer A: Behind the stop line, until the first vehicle has actually turned
Only the lead vehicle should move into the intersection to wait; a second vehicle inside it is likely to be stranded there when the light changes.
-
11. The driver ahead of you is straddling the lane line and is not signaling. How should you respond?
Show answer
Answer B: Stay back until you can see which lane that driver will take
A vehicle astride the line could move either way, so the only safe place is behind it where both possibilities are still covered.
-
12. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
13. You are stopped at the yield line of a roundabout when an emergency vehicle comes up behind you with lights and siren. What should you do?
Show answer
Answer A: Stay out of the roundabout and pull over to the right of your lane if there is room
Never enter a roundabout ahead of an emergency vehicle and never stop inside one; wait clear of the entry so the crew can get through.
-
14. What does the RESERVE position on a fuel supply valve do?
Show answer
Answer C: It draws on the small amount of fuel left at the bottom of the tank
A fuel supply valve normally offers OFF, ON, RESERVE and PRIME, and RESERVE taps the last of the fuel so the rider can reach a station.
-
15. As speed rises, which part of the total stopping distance grows the fastest?
Show answer
Answer B: The braking distance, which grows far faster than speed itself
Perception and reaction distances grow in step with speed, but braking distance grows roughly with the square of speed, so it dominates at higher speeds.
-
16. As a driver keeps drinking, in what order are driving abilities usually lost?
Show answer
Answer C: Judgment, then vision, reaction time and coordination
Alcohol reaches the parts of the brain that handle judgment first, and only later does it visibly affect sight, reactions and muscle control.
-
17. Who should set the pace of a group ride?
Show answer
Answer A: The last rider in the group, so that nobody is forced to hurry to keep up
The tail ender sets the pace: every rider watches the mirrors for the rider behind, and if someone falls back the whole group slows a little to stay together.
-
18. About how far does a vehicle travel in one second at 60 mph?
Show answer
Answer A: About 88 feet
At 60 mph you cover about 88 feet every second, which is why a glance of only two or three seconds means driving the length of several vehicles blind.
-
19. No plaque stating days or hours accompanies this sign at the intersection. When does the restriction apply?
Show answer
Answer D: At all times, since nothing limits it to particular periods
A regulatory restriction runs continuously unless a supplemental plaque states the days or hours during which it applies.
-
20. What is a designated driver?
Show answer
Answer A: Someone who agrees to drink nothing at all
A designated driver drinks no alcohol whatsoever, because any amount begins to affect judgment and the whole point is a sober driver.
