1. You are backing a trailer and want its rear to move to the left. Which way should you turn the steering wheel?
Show answer
Answer A: Move the bottom of the wheel to the left, which turns the top to the right
A trailer moves opposite to the tow vehicle's steering when backing. Holding the wheel at the bottom and moving your hand in the direction you want the trailer to go makes this easier.
-
2. A short driver cannot get ten inches between the chest and the steering wheel airbag. What is the answer?
Show answer
Answer D: Move the seat back and tilt the wheel downward, or fit pedal extenders
Distance from the airbag is gained by moving the seat back and aiming the wheel at the chest, using pedal extenders if the pedals are then out of reach.
-
3. Why should you avoid swinging wide to the left before making a right turn in a car?
Show answer
Answer A: Another driver may think you are turning left and try to pass on your right
Swinging left first misleads other road users about your intention and invites someone to move up on your right, exactly where you are about to go.
-
4. You are driving in the left lane at the posted speed limit and a line of vehicles has built up behind you. What should you do?
Show answer
Answer D: Move into a lane on your right when it is safe and let the traffic behind go by
Most states require traffic moving slower than the flow to keep right and reserve the left lane for passing, so a driver holding up a line of vehicles should move right when it is safe rather than block the lane.
-
5. An emergency vehicle with flashing lights and a siren is approaching from behind on a two-way street. What should you do?
Show answer
Answer C: Pull over to the right edge of the road and stop until it passes
Clearing a path by pulling to the right and stopping gives the emergency vehicle a predictable route, while stopping in mid-lane or inside an intersection blocks that path.
-
6. What is the benefit of looking far down the road rather than just ahead of the hood?
Show answer
Answer A: You steer with smaller corrections and you see trouble in plenty of time
A distant view steadies your steering and gives you time to plan, because you meet hazards after you have already seen them.
-
7. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
8. You are approaching a sharp curve. When should you reduce your speed?
Show answer
Answer D: Before you enter the curve, so you can accelerate gently through it
Braking hard inside a curve uses up the traction that is already being demanded for cornering, so the slowing must be finished before you enter.
-
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. You are driving slower than the general flow on a multilane highway. Which lane should you use?
Show answer
Answer D: The right lane, keeping the left lanes free for faster traffic and passing
Slower traffic must keep right so that faster vehicles and overtaking traffic can use the left lanes without weaving between lanes.
-
11. A flagger in a work zone turns a paddle so that the red octagonal face reading STOP is toward you. What must you do?
Show answer
Answer A: Stop completely and wait for the flagger to signal you forward
The STOP face of a flagger paddle requires a complete stop, and you may move again only when the flagger directs you to.
-
12. 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.
-
13. You are stopped at a stop sign waiting to turn onto a highway where traffic moves at 55 mph. How should you choose your gap?
Show answer
Answer A: Wait for a much larger gap than the one you would accept on a city street
Fast traffic covers ground while you are still accelerating, so the gap that feels adequate at 25 mph is dangerously short at highway speed.
-
14. The brake pedal goes to the floor and the vehicle does not slow. What should you try first?
Show answer
Answer C: Pump the pedal quickly to try to build pressure
Most vehicles have a split braking system, so rapid pumping can often build enough pressure to slow you. If it does not, use the parking brake gradually.
-
15. You arrive at an intersection with no signs, no signals and no markings at the same time as a vehicle on the road to your right. What must you do?
Show answer
Answer B: Yield to the vehicle on your right
At an uncontrolled intersection you must yield to a vehicle already in the intersection or approaching from your right.
-
16. 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.
-
17. A marked accessible space is signed as van accessible. What is different about it?
Show answer
Answer B: It has a wider aisle for a ramp or a lift to come out
The extra width beside the space is there so a side ramp or lift can deploy and a wheelchair can get clear of the vehicle.
-
18. A driver slows to walking pace at this sign, never stops rolling and eases into the intersection. How is that treated?
Show answer
Answer B: It is a violation, because the vehicle never came to a complete halt
What is required is a full halt with the wheels no longer turning, so slowing down, however carefully, does not satisfy it.
-
19. You are about to make a three-point turn on a narrow two-way street. What is the first step?
Show answer
Answer B: Pull close to the right edge, signal left and check traffic both ways
A three-point turn starts from a stop at the right edge with a left signal, and you only move once you have checked that both directions are clear.
-
20. You are leaving a private driveway and entering a public street. What are you required to do?
Show answer
Answer B: Stop and yield to traffic on the street and to pedestrians on the sidewalk
A driver entering a roadway from a driveway, alley or private road must stop and yield to traffic on the roadway and to pedestrians on the sidewalk being crossed.
-
21. How is the Georgia knowledge exam for a Class C or D credential structured?
Show answer
Answer B: Two parts of 20 items each, with 15 correct answers needed on each part
Georgia splits the exam into a road signs test and a road rules test, each with 20 items, and requires 15 correct answers on each part.
-
22. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
23. What does a broken line indicate, whatever color it is painted?
Show answer
Answer C: That crossing it is permitted
A broken line always describes a permissive condition, and the color then tells the driver whether the traffic beyond it runs the same way or the opposite way.
-
24. What are front fog lights for?
Show answer
Answer D: Adding a low, wide beam close to the car when visibility is poor
Fog lights throw a low, wide beam under the fog, which is why they are mounted low and are used only in poor visibility.
-
25. Which common non-prescription medicine is most likely to make a driver drowsy?
Show answer
Answer C: A cold or allergy remedy containing an antihistamine
Antihistamines in cold and allergy remedies are a leading cause of drowsiness behind the wheel, which is why the label carries a warning.
-
26. 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.
-
27. Which statement best describes what the basic speed law requires of you?
Show answer
Answer C: That you never drive faster than is reasonable and safe for the conditions
Nearly every state has a basic speed law that makes the conditions the real limit: weather, traffic, light and road surface can all require a speed well below the posted number.
-
28. The traffic signal is green, but the crossing lights on the tracks inside the intersection begin to flash. What must you do?
Show answer
Answer C: Stop clear of the tracks and wait, even though the signal is green
Active crossing warning devices outrank the green indication, so you stop short of the rails and wait until the warning stops.
-
29. On a multi-lane street, a yield line is painted well back from an unsignalized crosswalk rather than right at it. Why?
Show answer
Answer D: So drivers in the other lanes can see the pedestrian
Setting the yield line back keeps a stopped vehicle from hiding a crossing pedestrian from drivers in the next lane, which is a common cause of these crashes.
-
30. What is a driver being warned about here?
Show answer
Answer B: The pavement ahead carries vehicles traveling in the opposite direction
Beyond this point vehicles come the other way on the same pavement, which commonly happens where a one-way section or a separated stretch comes to an end.
-
31. You and the driver facing you both have stop signs at a two-way stop. You are going straight and that driver is turning left. Who has the right of way?
Show answer
Answer B: You do, and the turning driver must wait
Between two opposing drivers who both stopped, the one going straight goes first and the left-turning driver yields.
-
32. Your right wheels have dropped onto a soft shoulder. Why should you not steer straight back onto the pavement?
Show answer
Answer A: The tires can catch the pavement edge and throw you across the road
A tire pressed against the edge of the pavement climbs it suddenly, and at speed that jolt can send the vehicle across the center line.
-
33. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
34. A train has just passed a crossing that carries more than one set of tracks. What should you do?
Show answer
Answer B: Wait until the warning devices stop and you can see clearly along every track
A passing train can hide a second one coming on another track, so wait for the signals to clear and check each track before moving.
-
35. A strong wind is blowing across an open stretch of road. Besides the gusts, what else should you watch for?
Show answer
Answer A: Branches, dust and loose objects blown into your path
High wind strips branches, litter and dust onto the roadway and can push other vehicles out of their lane, so scan much further ahead than usual.
-
36. Where is a strong crosswind most likely to hit you suddenly?
Show answer
Answer D: Coming out of a tunnel or a cut onto an open bridge
Gusts arrive the moment you leave shelter, which is why bridge approaches and the ends of cuts and tunnels catch drivers out.
-
37. What does a traction control system do?
Show answer
Answer A: It limits wheel spin when you accelerate
Traction control cuts power or brakes a spinning wheel so the tires can grip when you pull away or accelerate on a slippery surface.
-
38. The passenger-side mirror on most vehicles is convex. What does this mean for the driver?
Show answer
Answer D: Vehicles in that mirror are closer than they appear
A convex mirror gives a wider view but shrinks what it shows, so a vehicle looks smaller and therefore farther away than it really is. Allow for this before changing lanes.
-
39. How do strong emotions affect driving?
Show answer
Answer B: They narrow your attention and make risky decisions more likely
Anger, worry and excitement all take attention away from the driving task and push drivers toward decisions they would not normally make.
-
40. You are approaching a yield sign on a ramp that joins a busy street. What does the sign require?
Show answer
Answer A: Slow down, be ready to stop, and let the other traffic go first
A yield sign means you must slow, be prepared to stop and give way to traffic on the road you are entering; a full stop is required only when traffic makes it necessary.
