1. The accelerator sticks open while you are driving. What is the first thing to do?
Show answer
Answer A: Shift into neutral and brake while steering off the road
Neutral disconnects the engine from the wheels so the vehicle can be braked normally, while shutting off the ignition may lock the steering and remove power assistance.
-
2. 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.
-
3. A driver on the street this sign governs is preparing to turn left at the next corner. Which lane should the vehicle be in beforehand?
Show answer
Answer A: The lane closest to the left curb
All the traffic here runs the same way, so nothing is coming toward the driver and the turn is taken from the extreme left lane rather than from beside the middle of the roadway.
-
4. What is the safest way to deal with a vehicle sitting in your blind spot?
Show answer
Answer A: Slow a little or move ahead so that it is no longer beside you
You cannot control the other driver, but you can change your own speed so that the vehicle is no longer hidden beside you.
-
5. You are clear of the tracks after your vehicle stalled on a crossing. Whom should you contact?
Show answer
Answer C: The emergency number posted on the blue sign at the crossing, or 911
Grade crossings carry an emergency notification sign with a railroad phone number and a crossing identification number so that approaching trains can be stopped, and 911 works if that sign is not visible.
-
6. A high-occupancy vehicle lane is separated from the general lanes by a pair of solid white lines with a gap every so often. Where may you enter or leave it?
Show answer
Answer D: Only at the openings where the solid lines are broken
The solid lines forbid crossing, so entry and exit are limited to the designated openings where the marking is broken.
-
7. On an overhead guide sign, the small exit number panel sits above the left-hand end rather than the right. What does that placement tell you?
Show answer
Answer A: The exit leaves from the left side of the roadway
The exit number plaque is placed on the side from which the ramp leaves, which gives advance notice of the unusual left-hand exit.
-
8. Does using a hands free device remove the risk of distraction?
Show answer
Answer A: No, the conversation still takes attention away from driving
Hands free equipment removes the manual part of the distraction but not the mental part, and a driver deep in conversation can look straight at a hazard without registering it.
-
9. How should a driver respond to this sign?
Show answer
Answer C: Slow down before reaching the rough spot and cross it at a steady, low speed
Losing speed before a sharp rise in the pavement keeps the vehicle settled, while braking or accelerating on top of it unsettles the suspension and costs grip.
-
10. What fine does DC set for exceeding the speed limit by 16 to 20 mph?
Show answer
Answer A: 150 dollars
Driving 16 to 20 mph over the limit in DC carries a 150 dollar fine, against 100 dollars for 11 to 15 mph over.
-
11. You are making a U-turn at a signal on a green left arrow. Who must you still watch for?
Show answer
Answer D: People in the crosswalk you will cross as you come around
Even a protected arrow does not clear the crosswalk, and a U-turn sweeps across a crosswalk that pedestrians may already be using.
-
12. A sign showing a walking figure inside a red circle with a diagonal slash stands at the start of a bridge. What does it mean?
Show answer
Answer C: People on foot may not use that roadway
The no pedestrians sign excludes people on foot from that roadway altogether, which is common on high-speed bridges and freeways.
-
13. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
14. You are behind three slow vehicles on a two-lane road and the way ahead looks clear. What is the sound decision?
Show answer
Answer D: Pass one vehicle at a time, if the road allows it
Passing several vehicles in one move keeps you in the oncoming lane far too long and leaves nowhere to go if a vehicle appears.
-
15. A motorcycle ahead of you has its turn signal blinking but continues straight through several intersections. What is the likely explanation?
Show answer
Answer D: Motorcycle signals often do not cancel themselves after a turn
Many motorcycle turn signals are not self-cancelling, so a rider may leave one on by mistake. Wait until the rider actually starts to turn before you act on the signal.
-
16. A pedestrian using a white cane or walking with a guide dog starts to cross the street ahead of you. What must you do?
Show answer
Answer A: Yield and stay stopped until the person has finished crossing
A white cane or guide dog identifies a pedestrian who may not be able to see your vehicle, so you must yield and wait rather than maneuver around the person. The horn can confuse the pedestrian or the dog.
-
17. 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.
-
18. What should you check on the hitch before towing a trailer?
Show answer
Answer B: That the coupler is locked and the safety chains are crossed underneath
The coupler must be latched and pinned, and the chains crossed under the tongue so they cradle it if the coupling lets go.
-
19. Your engine stalls while you are driving in traffic. What is the correct response?
Show answer
Answer A: Shift to neutral, try to restart it, and steer and brake toward the side of the road
With the engine off, power steering and power brake assistance fade, so steering and braking take more effort but still work. Neutral lets you attempt a restart while you coast to safety.
-
20. Travelling at about 55 mph on dry pavement, roughly how much room does an average car need to perceive, react and stop?
Show answer
Answer D: About 300 feet, close to the length of a football field
Reaction distance plus braking distance at 55 mph comes to roughly 300 feet on good dry pavement, and considerably more on a wet or loose surface.
-
21. The red brake warning light stays on after you release the parking brake. What should you do?
Show answer
Answer D: Stop safely and have the brakes checked before driving on
With the parking brake released, that light points to low fluid or a fault in one half of the braking system, which can leave you with very little braking.
-
22. 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.
-
23. A yellow diamond shows the two edges of the road pinching toward each other. What does it mean?
Show answer
Answer B: The pavement gets narrower but the lanes continue
The road narrows sign warns that the traveled way becomes tighter, leaving less room beside passing vehicles even though no lane is dropped.
-
24. You are stopped in slow traffic and a motorcycle comes up between the lanes. What should you do?
Show answer
Answer D: Hold your position and avoid any sudden lane change
The danger to a rider between lanes comes from a vehicle moving sideways without warning, so staying predictable is what protects them.
-
25. You must slow suddenly on a highway and a vehicle is following close behind you. What helps prevent a rear-end collision?
Show answer
Answer D: Tapping the brake pedal early so your brake lights flash a warning
Early brake light flashes give the driver behind more time to react, and slowing gradually instead of suddenly reduces the chance of being struck.
