1. What is the job of the hard outer shell of a motorcycle helmet?
Show answer
Answer D: To spread impact force and to resist objects punching through
The shell distributes a concentrated blow over a wide area and stops sharp objects from reaching the head, while the liner underneath absorbs the energy.
-
2. Your vehicle has stalled on railroad tracks and no train is in sight. After getting everyone away, whom should you call first?
Show answer
Answer B: The railroad emergency number posted on the blue sign at the crossing, giving the crossing number
Every public crossing has a blue emergency notification sign with a phone number and a crossing identification number. That call lets the railroad stop or slow trains before they reach you.
-
3. Which quality matters most in a face shield?
Show answer
Answer B: It resists penetration and is free of deep scratches
A shield has to stop objects thrown up from the road and stay clear enough for undistorted vision, and it needs some airflow so that it does not fog.
-
4. 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.
-
5. A stop sign at a busy corner has a stop line and a crosswalk, but buildings block your view of the cross street. What is the correct sequence?
Show answer
Answer C: Stop at the line first, then edge forward and stop again to see
The first stop is required at the line or before the crosswalk, and a second stop farther forward is what actually lets you yield safely.
-
6. A mixed drink is made with two shots of spirits. How much alcohol is that?
Show answer
Answer C: About two standard drinks
A standard drink is a fixed amount of pure alcohol, so a glass poured with two measures counts as two drinks however it is served.
-
7. 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.
-
8. A law enforcement officer is directing traffic and waves you forward while the signal facing you shows red. What should you do?
Show answer
Answer A: Follow the officer's direction and proceed
Directions given by an officer controlling traffic take priority over signals, signs and pavement markings.
-
9. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
10. Where should a rider in the middle of a group direct their attention?
Show answer
Answer A: Well ahead through the group and around it, not just at the rider in front
Watching only the machine ahead hides the traffic and hazards further up the road, and it leaves the rider reacting late to everything the group meets.
-
11. When may a passenger get off the motorcycle?
Show answer
Answer D: Only after the rider has stopped, braced the machine and said so
A passenger climbing off before the rider is ready removes weight from the back of a machine the rider is still holding upright, which can drop it.
-
12. When is a wet road usually most slippery?
Show answer
Answer C: Just after the rain starts, before the surface oil is washed away
Oil and dirt lying on the pavement mix with the first water and cut traction badly until continued rain washes the residue to the side of the road.
-
13. The gates at a railroad crossing begin to come down as you approach. What must you do?
Show answer
Answer A: Stop and wait until the gates are fully raised and the lights stop flashing
Once the gates start down you must stop clear of the tracks and wait until they are fully raised and the warning lights have stopped.
-
14. 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.
-
15. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
16. On a multi-lane street, a yield line is painted well back from an unsignalized crosswalk rather than right at it. Why?
Show answer
Answer D: So drivers in the other lanes can see the pedestrian
Setting the yield line back keeps a stopped vehicle from hiding a crossing pedestrian from drivers in the next lane, which is a common cause of these crashes.
-
17. When is a driver at the highest risk of falling asleep at the wheel?
Show answer
Answer B: Late at night, early morning and mid afternoon
The body clock produces its deepest dips in alertness in the small hours and again in the middle of the afternoon, and crash records follow those dips.
-
18. What is the maximum lawful speed on a District street where no other speed is posted?
Show answer
Answer A: 20 mph
Unless a sign says otherwise, the maximum lawful speed on District streets and highways is 20 mph.
-
19. Why are ordinary denim jeans a poor choice for riding?
Show answer
Answer C: They wear through in a slide, giving little abrasion protection
Light denim abrades away in a fraction of a second on pavement, while leather or purpose made textile gear stays intact long enough to protect the skin underneath.
-
20. What is lane splitting?
Show answer
Answer B: A motorcycle riding between two lanes of traffic moving the same way
Lane splitting means riding along the line between two lanes of traffic going in the same direction rather than staying within a lane.
-
21. You expect to be out after dark on a sunny day's ride. What should you plan for eye protection?
Show answer
Answer B: Carry a clear shield to change to when the light drops
A tint that helps in daylight steals light you need at night, and riding with no eye protection is not the answer, so carry a clear shield and change it at dusk.
-
22. You are approaching a narrow bridge where the road has one lane in each direction and no shoulder. What should you do about passing?
Show answer
Answer B: Do not pass on or near the bridge
A narrow bridge gives neither vehicle anywhere to go, so passing is prohibited there in the same way as on a hill or in a tunnel.
-
23. You are clear of the tracks after your vehicle stalled on a crossing. Whom should you contact?
Show answer
Answer C: The emergency number posted on the blue sign at the crossing, or 911
Grade crossings carry an emergency notification sign with a railroad phone number and a crossing identification number so that approaching trains can be stopped, and 911 works if that sign is not visible.
-
24. May you stop briefly across the sloped ramp that joins the sidewalk to the street at a corner?
Show answer
Answer B: No, that ramp must stay clear for people using wheelchairs
A curb ramp is the only way many people can get from the sidewalk to the crosswalk, so blocking it even briefly is prohibited.
-
25. You are turning left across tracks that run along the center of the street. What should you do before crossing them?
Show answer
Answer B: Look along the tracks in both directions and cross only when clear
Rail vehicles running in the street can arrive from either direction and cannot stop quickly, so look along the tracks before you turn across them.
