1. A driver stopped at a red signal wants to turn right and this sign is posted at the corner. What is permitted?
Show answer
Answer A: Nothing: the turn is barred whether the signal is red or green
The restriction works independently of the signal, so the usual permission to turn right after stopping at a red light does not exist where this sign is posted.
-
2. An oncoming car is waiting to turn left across your path at an intersection. What is the safest response?
Show answer
Answer D: Slow, cover the brakes and pick a lane position that keeps an escape path
A car turning left in front of a rider is one of the most common motorcycle collisions, so the rider prepares to stop or swerve rather than trusting the driver to wait.
-
3. You turn from asphalt onto a loose gravel road. What should you do about your speed?
Show answer
Answer D: Lower it, since grip is reduced and stopping takes longer
Loose gravel gives far less grip than pavement, so speed must come down for both steering and stopping.
-
4. What do the grooves in a tire tread do on a flooded road surface?
Show answer
Answer B: They give the water a way to escape so the tread can touch the road
Tread grooves pump water out from under the tire so rubber can meet pavement. A worn tread moves less water, so hydroplaning starts sooner.
-
5. You reach a red light with a sign reading NO TURN ON RED. What may you do?
Show answer
Answer D: Wait for the green; no turn is allowed while the light is red
That sign removes the usual permission to turn on red at the intersection, so you must wait for a green indication.
-
6. What does this sign tell a driver about the road ahead?
Show answer
Answer A: The roadway changes direction ahead, so speed should be reduced before reaching it
It gives advance notice of a change in alignment so the driver can slow down before entering, since braking inside a bend uses up grip that is needed for steering.
-
7. On a long uphill grade a second lane opens on the right and a sign directs slower traffic into it. You are towing a trailer and holding up a line of vehicles. What should you do?
Show answer
Answer A: Move into the right-hand lane and let the faster traffic use the left lane
A climbing lane exists so that slow vehicles can be passed safely, and the slower vehicle is the one that belongs in it.
-
8. Federal law lets a state open its high-occupancy vehicle lanes to certain vehicles carrying only one person. Which of these is covered by that allowance?
Show answer
Answer B: Motorcycles
Federal law lets states allow motorcycles into high-occupancy vehicle lanes regardless of the number of occupants, because keeping riders in the flow is safer than the alternative.
-
9. You are following another vehicle down a long, steep grade. What should you do about the gap?
Show answer
Answer D: Make it longer, because both of you need more room to stop
Everything takes longer to stop on a downgrade, including the vehicle ahead, so the gap that works on the flat is no longer enough.
-
10. How should you follow a school bus in traffic?
Show answer
Answer A: Far enough back to see its lights and stop in time
A school bus stops often and with little warning, so a longer following distance gives you time to see the lights come on and stop clear of it.
-
11. A crash happens directly in front of you and vehicles are blocking both lanes. What should you do?
Show answer
Answer B: Stop at a safe distance, put on the hazards and warn the traffic behind
The greatest danger after a crash is a second collision, so stop short of it and make sure the traffic behind you can see the problem.
-
12. A turn restriction sign at the corner shows a range of times below the symbol. What does that mean?
Show answer
Answer A: The turn is banned only during the hours shown on the sign
Times posted under a regulatory symbol set the period during which the restriction applies; outside those hours the movement is permitted.
-
13. The temperature gauge climbs toward the red while you sit in slow moving traffic. What should you do?
Show answer
Answer A: Get out of the traffic as soon as it is safe and let the engine cool
A stationary motorcycle gets almost no airflow through the engine or radiator, so the cure is to stop creeping along in traffic and let it cool.
-
14. A friend who has been drinking insists on driving home. What is the right thing to do?
Show answer
Answer B: Take the keys and arrange a sober ride, even if the friend objects
An impaired driver is dangerous on any street at any speed, and coffee does not lower blood alcohol. Keeping the keys and finding another way home is the only safe choice.
-
15. You are turning left from a two-way street onto another two-way street. Where should you begin and end the turn?
Show answer
Answer B: Begin in the lane just right of the center line and finish just right of the center line of the new street
You approach a left turn from the lane closest to the center line and enter the new roadway just to the right of its center line, which keeps you clear of oncoming traffic.
-
16. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
17. A sign at the curb reads Tow-Away Zone. What does it mean for you?
Show answer
Answer C: That a vehicle left there can be removed at the owner's expense
In a tow-away zone the vehicle can be removed immediately and the owner pays the towing and storage charges to get it back.
-
18. A driver reaching a stop sign is required to do what?
Show answer
Answer D: Come to a complete stop and then proceed only when it is safe
A stop sign requires a full stop before the stop line, crosswalk or intersection, after which the driver may go on once the way is clear.
-
19. What is the PRIME position on a fuel supply valve used for?
Show answer
Answer D: To let fuel flow into the carburetor after the machine has stood unused
PRIME bypasses the normal vacuum control and lets fuel refill an empty carburetor, which helps a machine start after sitting for a long time.
-
20. Where must the engine cut-off switch be set before the starter button will crank the engine?
Show answer
Answer A: In the run position
The cut-off switch sits in the ignition circuit, so the engine will not start or run while it is set to off.
