1. A group in formation needs to change lanes. What is the safest way to do it?
Show answer
Answer A: The leader starts the change early enough for the whole group to complete it
Beginning the change early gives the entire formation the road and the time it needs to move over together instead of scattering across two lanes.
-
2. After an hour on a hot highway your tire pressure reads higher than it did in the morning. What should you do?
Show answer
Answer D: Nothing, because pressure rises when tires heat up
Air expands as the tire warms, so a hot reading is normally above the cold setting. Bleeding air off would leave the tire underinflated once it cooled.
-
3. About how far behind a tractor-trailer does the driver's rear blind spot reach?
Show answer
Answer C: Around 30 feet
The area behind a large truck is hidden for roughly 30 feet, so a driver tucked in there cannot be seen at all.
-
4. Before making a right turn at an intersection, what should you check besides oncoming traffic?
Show answer
Answer B: Your right blind spot and the crosswalk, for cyclists and pedestrians
Right turns often catch a cyclist or a pedestrian coming up on the right, so check the blind spot and the crosswalk before you turn.
-
5. You are behind a slow vehicle on a two-lane road and a marked passing lane begins a mile ahead. What is the sensible choice?
Show answer
Answer D: Wait for the passing lane rather than using the opposing lane
A passing lane lets you overtake without ever entering the lane used by oncoming traffic, which is far safer than a pass a minute earlier.
-
6. You are turning left out of a driveway onto a busy two-way street. What must you do?
Show answer
Answer D: Wait for a gap in both directions before you start to move
The turn crosses one direction of traffic and joins the other, so you need a gap in both before leaving the driveway rather than stopping across a lane.
-
7. What does research say about the effect of a full coverage helmet on a rider's ability to see and hear traffic?
Show answer
Answer B: It leaves the view and the useful hearing a rider needs largely intact
Certified helmets leave far more peripheral vision than a rider needs to check traffic, and riders wearing them still hear the sounds that matter.
-
8. 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.
-
9. An orange background with a black legend on a sign indicates
Show answer
Answer B: a temporary traffic control or work zone situation
Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.
-
10. A funeral procession with headlights on is crossing an intersection when your light turns green. What should you do?
Show answer
Answer A: Wait and let the whole procession go through
Most states let a funeral procession stay together once the lead vehicle has lawfully entered an intersection, and in every state you must yield to vehicles already in the intersection, so wait until the line has passed.
-
11. Why is it better for a passenger to hold the rider's waist or hips rather than the rider's shoulders?
Show answer
Answer A: Weight held low is less likely to disturb the rider's steering
Pulling on the shoulders feeds the passenger's movement straight into the rider's arms and handlebars, while a grip at the waist keeps that weight low and central.
-
12. Why does riding in moderately cold weather call for extra layers of clothing?
Show answer
Answer B: Chill and fatigue set in quickly and reduce the rider's control
Wind at riding speed strips body heat away fast, and a chilled, tired rider reacts more slowly and can slide into hypothermia.
-
13. What causes the side to side motion a rider feels when crossing a steel grid deck or rain grooves?
Show answer
Answer C: The tires following the ridges and grooves, which is normal and harmless
The tread follows the pattern in the surface, which produces a wandering feel. The motorcycle is not out of control, so relax on the bars and hold your speed.
-
14. How should the brake light be checked before a ride?
Show answer
Answer D: Confirm that the hand lever and the foot pedal each switch it on
Many motorcycles use a separate switch for each brake control, so both the lever and the pedal have to be tested one at a time.
-
15. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
16. What is sensible when you drive in an unfamiliar town for the first time?
Show answer
Answer C: Drive a little slower and give yourself more time to read the signs
In unfamiliar surroundings you need longer to take in signs, junctions and markings, and lower speed buys that time.
-
17. You are involved in a collision, even a minor one. What is your first legal duty?
Show answer
Answer A: Stop at or near the scene without blocking traffic more than necessary
Every driver involved in a crash must stop at the scene, and leaving before meeting that duty is a serious offense. Move the vehicles only as far as needed to clear the traffic lanes.
-
18. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
19. What should you confirm about your saddlebags before riding away?
Show answer
Answer A: That both are latched shut and neither is overloaded
An unlatched or overstuffed bag can swing open or sag into the rear wheel or the exhaust, either of which can wreck the machine's handling at once.
-
20. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?
Show answer
Answer D: The sign that forbids entering that roadway at all
The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.
-
21. You come to a place where a storm has dropped a power line across the road ahead. What should you do?
Show answer
Answer B: Stop well back, keep everyone away from it and report it to the police
A downed line may be live and can energize the ground around it, so keep well clear and let the utility or the police handle it.
-
22. A freeway sign reads BUSES ONLY ON SHOULDER 6 AM TO 9 AM. Who may drive on the shoulder then?
Show answer
Answer A: Only the vehicles named on the sign, during the hours shown
Shoulder running is granted by the sign to the class of vehicle and the hours the sign names, and it does not turn the shoulder into a general travel lane.
-
23. A bus stopped at the corner hides the crosswalk you are about to turn across. What should you do?
Show answer
Answer C: Turn slowly, ready to stop for anyone stepping out in front of it
People often step into the road from in front of a stopped bus, so approach the hidden crosswalk slowly and be ready to stop.
-
24. A farm implement ahead of you on a two-lane road is wider than its own lane. What should you do?
Show answer
Answer D: Hang back until you can see past it and pass only with a clear road
Wide equipment hides the road ahead and may extend farther across the center line than it appears, so the pass needs more room and a much better view.
-
25. You are passing a large truck on an open highway in a strong crosswind. What should you expect?
Show answer
Answer A: A push toward the truck, then a push the other way as you clear it
The truck shelters you as you go by and then releases you into the full gust, so the load on the steering changes twice during the pass.
