1. Why should riding boots come above the ankle?
Show answer
Answer C: The ankle is easily broken and is left bare by a low shoe
The ankle takes a lot of damage when a motorcycle goes down or a foot is trapped, and a low shoe leaves it completely unprotected.
-
2. A yellow diamond shows two lanes narrowing into one. What does it require of a driver?
Show answer
Answer D: Adjusting speed and merging before the lane disappears
The lane ends sign gives notice that one lane will be dropped, so drivers should adjust speed and blend into the continuing lane in good time.
-
3. What condition does this sign warn a driver about?
Show answer
Answer B: Another road joins the road being traveled, from one side
It announces a side road entering the main roadway, so the driver should expect vehicles waiting to pull out and other vehicles slowing to turn in.
-
4. Your low beams light about 250 feet of road, but at your speed you would need more than that to stop. What is that called?
Show answer
Answer D: Overdriving your headlights
When your stopping distance is longer than the stretch of road your headlights show, you cannot react to anything you finally see. Slow down until you can.
-
5. You are waiting in a left-turn lane at a green light when a fire engine with lights and siren comes toward you in the oncoming lanes. What should you do?
Show answer
Answer D: Hold your position and let the fire engine pass
Turning across the path of an approaching emergency vehicle is exactly what you must not do; stay put until it has gone by.
-
6. 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.
-
7. A driver who wants to reverse direction arrives at this sign. What is allowed?
Show answer
Answer C: Going on and reversing direction only where the maneuver is permitted
The restriction removes that maneuver at that spot entirely, so the driver has to continue and turn the vehicle around at a place where it is not prohibited.
-
8. Halfway through a curve you realize you are going too fast. What is the best response?
Show answer
Answer C: Ease off the gas gently and look where you want to go
Easing off transfers a little weight to the front tires without upsetting the balance, and looking through the curve keeps your steering smooth.
-
9. Why can a motorcycle ahead of you slow down without any warning light showing?
Show answer
Answer B: The rider may slow by downshifting or rolling off
Riders often lose speed by closing the throttle or changing down, which does not switch on the brake light, so watch the machine itself and keep back.
-
10. 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.
-
11. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
-
12. A steady red arrow is displayed for your left-turn lane at a two-way intersection. What must you do?
Show answer
Answer C: Stop and remain stopped until an indication permits the turn
A steady red arrow prohibits the movement it points to, so the driver stops and waits for a green arrow, a flashing yellow arrow or another indication that permits the turn.
-
13. On a rainy road, where can a rider usually find the best traction?
Show answer
Answer A: In the tire tracks left by the vehicles ahead
Vehicles ahead push water aside and keep their tracks clearer of oil, so those tracks generally give better grip than the rest of the lane.
-
14. What should a group agree on before the ride begins?
Show answer
Answer A: The route, the fuel and rest stops, and the hand signals to be used
Settling the route, the stops and the signals before departure keeps the group together and avoids sudden, confusing decisions once it is moving.
-
15. You are approaching the crest of a hill and cannot see the road beyond it. What should you do?
Show answer
Answer C: Slow down and keep well to the right
Beyond a blind crest there may be a stopped vehicle, a cyclist or an oncoming driver crossing the center line, so reduce speed and hold your own side.
-
16. A sign with a green background and a white legend normally provides
Show answer
Answer A: directions, distances and destinations
Green is the background color of the guide sign series, which names routes and destinations and gives the distance to them.
-
17. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
18. A yellow diamond on an exit ramp shows a truck tipping over onto two wheels. Which drivers does it concern most?
Show answer
Answer D: Those in tall vehicles carrying a high load
The truck rollover sign warns that the curve can overturn a vehicle with a high center of gravity, so such drivers must slow well below the normal ramp speed.
-
19. Why does full riding gear matter on a short trip around the neighborhood?
Show answer
Answer D: Pavement takes skin off at 25 miles an hour just as it does at 55
Serious injuries happen at ordinary street speeds and close to home, so gear that is worth wearing on a long trip is worth wearing on a short one.
-
20. 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.
-
21. 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.
-
22. You have just returned to your own lane after passing. Why should you not slow down straight away?
Show answer
Answer A: The vehicle you passed is close behind and needs room to stop
Returning and then braking leaves the driver you just overtook with almost no following distance, which is how a pass turns into a rear-end collision.
-
23. How should a helmet sit on the head once it is fastened?
Show answer
Answer C: Level on the head, with the eye port giving a clear view of the road
A helmet worn level protects the forehead and gives full vision, while one pushed back leaves the forehead exposed in a crash.
-
24. About how far does a vehicle travel in one second at 60 mph?
Show answer
Answer A: About 88 feet
At 60 mph you cover about 88 feet every second, which is why a glance of only two or three seconds means driving the length of several vehicles blind.
-
25. At a stop sign with a painted stop line and a crosswalk, where must you stop?
Show answer
Answer D: At the stop line, before it and before the crosswalk
You stop at the stop line first, and only if there is no stop line do you stop before the crosswalk, and only if there is neither do you stop before entering the intersection.
