1. A motorcycle ahead of you is weaving slightly as it crosses a stretch of grooved pavement. What should you do?
Show answer
Answer D: Give the rider extra room until the surface improves
Grooves, metal plates and loose material affect a motorcycle far more than a car, so back off and let the rider deal with the surface.
-
2. A yellow sign shows a truck on a slope with the legend 7 PERCENT GRADE. What should a driver of a heavy vehicle do?
Show answer
Answer A: Select a lower gear before starting down
The percentage shows how steep the descent is, and choosing a low gear at the top lets the engine hold the vehicle back instead of the brakes overheating.
-
3. 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.
-
4. Your phone is in a mount on the dashboard rather than in your hand. What is true?
Show answer
Answer B: It still takes your eyes and mind off the road
A mount solves the hand problem but not the eye or the mind problem, and reading or tapping a mounted screen costs the same seconds of attention.
-
5. An arrow panel in a work zone shows four flashing lamps in caution mode instead of an arrow. What does that display mean?
Show answer
Answer A: Warning only, so pass the work area with caution in your current lane
Caution mode gives a general warning without directing a lane change, so drivers stay alert and pass the activity with care.
-
6. A preferential lane sign reads HOV 2+ and lists the hours it applies. During those hours, which vehicles may use the lane?
Show answer
Answer A: Vehicles carrying at least two people, counting the driver
The number on an HOV sign is the minimum number of occupants, driver included, that a vehicle must carry to use the lane while the restriction is in effect.
-
7. Warning signs such as stop ahead, yield ahead and signal ahead are installed mainly where
Show answer
Answer B: the traffic control device cannot be seen from far enough away
These advance warning signs are used when a crest, curve or obstruction keeps the stop sign, yield sign or signal from coming into view in time for a driver to react.
-
8. You are moving at walking pace through a crowded parking area. Which combination gives the steadiest control?
Show answer
Answer B: Steady throttle, the clutch held in the friction zone and light rear brake
Slipping the clutch in the friction zone against a steady throttle and a light drag of rear brake keeps power smooth and the machine stable below walking speed.
-
9. What is the function of a regulatory sign?
Show answer
Answer A: To inform road users of traffic laws or regulations that apply at that location
Regulatory signs state requirements that carry the force of law where they are posted, so disregarding one is a violation rather than a lapse of judgment.
-
10. Which color scheme is standard for the drums and barricades that channel traffic through a work zone?
Show answer
Answer C: Alternating orange and white retroreflective stripes
Drums and barricades carry alternating orange and white retroreflective stripes, and the traffic cones used in the same zones are predominantly orange.
-
11. 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.
-
12. What does a NARROW BRIDGE warning sign tell a driver?
Show answer
Answer A: The bridge is tighter than the road leading up to it
A narrow bridge still carries both directions, but with much less clearance than the approaches, so drivers should slow and hold their lane position carefully.
-
13. Which formation lets a group of riders stay close together while every rider keeps an adequate space cushion?
Show answer
Answer A: A staggered formation
A staggered formation keeps the group compact enough for traffic while still leaving each rider room to the front, the rear and both sides.
-
14. A large truck ahead of you swings toward the left just before turning right at an intersection. What should you do?
Show answer
Answer B: Stay back and never try to move into the gap between the truck and the curb
Long vehicles need extra room and often swing wide to complete a right turn, so the space that opens on their right closes again as the trailer sweeps through it.
-
15. May you park across the entrance to a fire station?
Show answer
Answer D: No, an emergency exit must never be blocked
Emergency vehicles must be able to leave the moment a call comes in, so their entrances and exits are kept clear at all hours.
-
16. Why do streetcar or light rail rails set into a street deserve extra care from a rider?
Show answer
Answer B: The groove alongside the rail can catch a front tire crossed at a shallow angle
The groove beside an embedded rail is just wide enough to trap a motorcycle tire, so cross rails at as steep an angle as your lane allows.
-
17. In the code that governs pavement markings, what does a double line stand for?
Show answer
Answer B: A maximum restriction
The marking code is consistent: a double line means the strongest restriction, a solid line discourages or forbids crossing, and a broken line is permissive.
-
18. 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.
-
19. You are riding where fresh pavement meets an older lane that sits an inch or two lower. How should you move across that edge?
Show answer
Answer A: Slow down and cross the edge at as sharp an angle as the lane allows
A pavement edge break can steer the front wheel along it if you meet it at a shallow angle, so slow, hold the bars firmly and cross it steeply.
-
20. A bag strapped to the back of your motorcycle works loose and starts to shift as you ride. What should you do?
Show answer
Answer C: Slow smoothly, pull off the road, and secure the load before riding on
A load that moves changes the balance of the motorcycle and can foul a wheel or the chain, so stop as soon as you safely can and fasten it properly.
-
21. 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.
-
22. What is the only reliable remedy for a driver who is sleepy?
Show answer
Answer A: Sleep
Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.
-
23. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?
Show answer
Answer A: Wait until the gates rise completely and the lights go out
Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.
-
24. You are the first to arrive at a crash on a rural road. What should you do first?
Show answer
Answer C: Park well clear of the scene, put on your hazard lights and call for help
Getting trained help on the way and keeping the scene visible does more good than anything an untrained bystander can do.
-
25. Which effect appears as a drinker's blood alcohol level climbs well past the first drinks?
Show answer
Answer D: Loss of muscle control and steady steering
Higher levels of alcohol reach the parts of the brain that control movement, which shows up as clumsy steering, late braking and poor lane control.
