1. What does the choke, or enrichener, do on a motorcycle that has one?
Show answer
Answer B: It gives the engine a richer fuel mixture so a cold engine will start
A cold engine needs more fuel in proportion to air, and the choke supplies that richer mixture until the engine warms up.
-
2. Which part of the body operates the gearshift lever?
Show answer
Answer B: The left foot
The gearshift lever sits ahead of the left footrest and is moved up or down with the left foot.
-
3. Railroad tracks cross the road at a slight angle. What is normally the safest way to cross them?
Show answer
Answer B: Ride straight across while staying inside your own lane
Riding straight ahead within your lane is usually safe on tracks that cross the road, because swerving to square them up can carry you into another lane or into oncoming traffic.
-
4. At night you are judging your distance from the rider ahead by their tail light. What is the risk?
Show answer
Answer A: A single small light gives a poor sense of how far away it really is
Distance is very hard to judge from one small light in the dark, so riders should leave extra space rather than trust the impression the light gives.
-
5. The road ahead is broken up with potholes and rough patches. What should you do?
Show answer
Answer C: Slow down, since a hole hit at speed can wreck a tire or wheel
A lower speed cuts the impact on tires, wheels and suspension and gives you time to choose a line through the rough surface.
-
6. A downpour has just started on a street with a visible dark strip down the middle of the lane. Where should you ride?
Show answer
Answer A: In the left or right portion of the lane, away from the greasy center strip
Dripped oil and grease build up in the center of the lane, and water floats that film to the top, so the tire tracks on either side offer better grip.
-
7. You are following a car at night with the high beam on. What should you do?
Show answer
Answer C: Switch to the low beam so the driver ahead is not blinded
A high beam fills the mirrors of the vehicle ahead and blinds its driver, which is dangerous for the very driver most able to affect the rider.
-
8. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
9. You are stopped at a steady red arrow pointing right, and no sign or state rule permits turning on a red arrow. May you turn right?
Show answer
Answer A: No, you must wait until the red arrow goes out and a green signal appears
A steady red arrow prohibits the movement it points to until a signal permitting it appears. Only a posted sign or a specific state rule allows a turn on a red arrow after a complete stop, so without one you must wait.
-
10. A sign on a long descent points to a RUNAWAY TRUCK RAMP a mile ahead. What is that ramp for?
Show answer
Answer C: Stopping a vehicle whose brakes have failed
An escape ramp climbs into deep gravel or sand to bring a vehicle with failed brakes to a halt, so no one should stop or park in it.
-
11. You are in the acceleration lane and the gap you were aiming for is now beside you. What is the best adjustment?
Show answer
Answer A: Change your speed a little to line up with a gap, then merge smoothly
The acceleration lane is for matching both the speed and the position of a gap, and small speed adjustments are what line the two up.
-
12. When should a helmet be replaced?
Show answer
Answer B: After a crash, or if the shell is cracked or the straps are frayed
The energy absorbing liner is designed to crush once, so a helmet that has taken an impact or shows damage no longer offers full protection.
-
13. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
14. 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.
-
15. The word SCHOOL is painted in large letters across the roadway. What is it doing?
Show answer
Answer D: Backing up the signs marking a school zone
Word markings on the pavement reinforce a message that is already signed, and a driver looking at the road ahead cannot miss them.
-
16. 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.
-
17. Your front wheel drops off the edge of the pavement onto a lower shoulder. What is the safest way back?
Show answer
Answer D: Ride straight, slow down, then turn back sharply enough to cross the edge
Trying to climb a raised pavement edge at a shallow angle lets the tire slide along it, so the rider settles first and then crosses the edge at a sharp angle.
-
18. In a tight, slow speed turn such as a parking lot U-turn, the rider should:
Show answer
Answer C: Lean the motorcycle while keeping the body upright
Keeping the body upright while the motorcycle leans lets the machine turn tightly and helps the rider hold balance at very low speed.
-
19. A lane along the right edge is set off by a solid white line and marked with a bicycle symbol. How should a driver treat it?
Show answer
Answer B: Stay out of it except for the short distance needed to turn or cross where that is allowed
A marked bicycle lane is set aside for bicycle traffic, and motor vehicles may enter it only briefly where turning or crossing is permitted.
-
20. Why is parking too close to a street corner prohibited?
Show answer
Answer D: Because it hides approaching traffic and pedestrians
A vehicle parked at a corner blocks the view that both drivers and pedestrians need before entering the intersection.
-
21. Which combination best reduces the chance of hydroplaning?
Show answer
Answer D: Good tread depth, correct tire pressure and lower speed in the rain
Tread channels water away, correct pressure keeps the tire's shape, and lower speed gives the tire time to push water aside. Hydroplaning can begin at surprisingly modest speeds.
-
22. Approaching the point this sign refers to, which hazard is most likely?
Show answer
Answer A: A vehicle pulling out from the entering road into the driver's path
The main risk is a driver on the entering road who misjudges the gap and pulls out, so covering the brake and being ready to slow is the sensible response.
-
23. On traffic control devices, the color green shows direction to a destination and also shows
Show answer
Answer C: that a movement is permitted
Green carries two assignments: guidance toward destinations, and the idea that the movement shown is allowed, as on a green arrow.
-
24. What does a sign showing a bicycle inside a red circle with a diagonal slash prohibit?
Show answer
Answer D: Riding a bicycle on that roadway
This is a selective exclusion sign, used where bicycles are banned from a road such as a freeway or a tunnel.
-
25. 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.
