1. You are entering a marked work zone. What should you expect?
Show answer
Answer B: A reduced posted speed, narrowed or shifted lanes, and traffic that may stop suddenly
Work zones change the geometry of the road and can bring traffic to a halt without warning, so the posted work zone speed and increased following distance both apply.
-
2. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
-
3. You are leaving a freeway at an exit that has a deceleration lane. Where should you slow down?
Show answer
Answer C: After you have moved fully into the exit lane
Braking in a through lane surprises the traffic behind you, so you move into the exit lane at highway speed and then slow down inside it.
-
4. Some toll facilities use signs and markings with a purple background or a purple stripe. What do they identify?
Show answer
Answer D: Lanes reserved for vehicles with an electronic toll account
Purple is assigned to lanes and ramps restricted to vehicles with a registered electronic toll collection account, so drivers without one must stay out.
-
5. How do stimulant drugs such as amphetamines or cocaine typically affect driving?
Show answer
Answer D: They can make the driver overconfident and more willing to take risks
Stimulants create a false sense of alertness and encourage aggressive, risky driving. When they wear off, sudden fatigue can follow.
-
6. At night you are waiting to turn left and can see only the headlights of an approaching vehicle. Why should you allow a bigger margin?
Show answer
Answer D: Because lights alone make speed and distance hard to judge
With no other visual cues, two points of light give you very little information about how fast the vehicle is closing, so leave extra margin.
-
7. You are about to leave a roundabout when a pedestrian steps into the crosswalk on your exit. What should you do?
Show answer
Answer B: Yield to the pedestrian and wait for the crosswalk to clear
Roundabout crosswalks sit on the entries and exits, and drivers must yield to pedestrians using them.
-
8. The school bus stop ahead sign is installed where
Show answer
Answer C: a school bus stop cannot be seen from far enough away by approaching drivers
This school warning sign is used in advance of a bus stop that lacks adequate sight distance and cannot be relocated, so drivers are warned before the stopped bus comes into view.
-
9. What is the driver expected to do after passing this sign?
Show answer
Answer A: Begin slowing so that a complete stop can be made at the intersection ahead
It is used where the control at the intersection stays hidden until late, so braking should begin here rather than at the stop line.
-
10. What is the correct position for the feet while riding?
Show answer
Answer C: Firmly on the footrests with the toes level
Toes kept level stay clear of the pavement when the motorcycle leans and leave the foot ready to reach the brake pedal or shift lever.
-
11. 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.
-
12. A rider notices scalloped, uneven wear across the front tire. What does that suggest?
Show answer
Answer C: A suspension or wheel bearing fault that should be inspected
Cupped or scalloped wear normally points to worn fork components or loose wheel bearings letting the tire bounce as it rolls.
-
13. Why is it harder to read the road surface at night once it has rained?
Show answer
Answer B: The wet surface throws light away and hides holes and markings
Light from your headlight bounces off wet pavement instead of coming back to you, and reflections of other lights mask the surface, so slow down and open up your following distance.
-
14. You are riding in the middle of a tight cluster of cars on a multilane road. What is the best way to improve your safety?
Show answer
Answer C: Ride slightly faster or slower to open space and get clear of the cluster
A rider hemmed in on all sides has nowhere to go, so change your speed a little to open an escape path and leave the crowd.
-
15. You have a green arrow to turn left. What still applies?
Show answer
Answer D: You must yield to any pedestrian or vehicle still inside the intersection
A green arrow protects your turn from conflicting traffic, but you must still let anyone already in the intersection get clear before you move.
-
16. The group has become separated and the leader wants to wait for the missing riders. Where should the leader pull in?
Show answer
Answer C: In a parking area or other space that is clear of moving traffic
Waiting somewhere off the roadway keeps the parked machines and their riders out of traffic and gives the arriving riders room to pull in safely.
-
17. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?
Show answer
Answer B: Obstruction of the normal flow of traffic, which is prohibited in itself
Driving so slowly that other traffic is impeded is an offense in its own right when nothing about safety, weather or the road calls for it.
-
18. Your light turns green, but a vehicle from the cross street is still finishing a turn inside the intersection. What should you do?
Show answer
Answer B: Wait until that vehicle has cleared the intersection
A green indication lets you proceed only after yielding to pedestrians in the crosswalk and to vehicles already lawfully within the intersection.
-
19. What must you be sure of before you pull out to pass on a two-lane road?
Show answer
Answer A: That the road ahead is clear far enough for the whole pass
You need enough clear road to pull out, pass and return before any oncoming vehicle arrives, and you must judge that distance before you start.
-
20. The signal turns green as you approach an intersection. What is the safest practice?
Show answer
Answer B: Look left, then right, then left again, and make sure the intersection is clear before entering
A green light gives permission but does not guarantee the intersection is empty, and a quick scan catches a vehicle running the red or a pedestrian still crossing.
-
21. What is true about driving away from a crash you were involved in?
Show answer
Answer B: It is a serious offense, even if the other driver has driven away too
Leaving the scene is a criminal offense in every state, and the behavior of the other driver does not excuse it.
-
22. Which action becomes clearly more risky beyond this sign?
Show answer
Answer A: Using the left side of the roadway to overtake
With vehicles coming the other way on the same pavement, overtaking on the left needs enough clear road to pull out, pass and return, which is often not available.
-
23. Which statement best describes what the basic speed law requires of you?
Show answer
Answer C: That you never drive faster than is reasonable and safe for the conditions
Nearly every state has a basic speed law that makes the conditions the real limit: weather, traffic, light and road surface can all require a speed well below the posted number.
-
24. What does a shaft final drive need checked before a ride?
Show answer
Answer D: The fluid level in the final drive housing, and any sign of leaks
A shaft drive runs in its own oil bath, so the pre-ride check is the fluid level and any leak around the housing seals rather than tension or slack.
-
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.
