1. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
2. A reduced speed limit posted with this sign and a plaque giving hours is in force
Show answer
Answer C: during the hours shown on the plaque, or while the beacon is flashing
A school speed limit applies during the periods stated on the plaque or while the attached beacon flashes, and the regular limit governs outside those periods.
-
3. On a two-lane road with a broken yellow center line, may you cross it to turn into a driveway on the left?
Show answer
Answer C: Yes, when it is safe and the oncoming lane is clear
A broken center line may be crossed for a pass or for a left turn into a road or a driveway, once the oncoming lane is clear.
-
4. A driver's blood alcohol concentration is below the legal limit, but the driver is visibly impaired. Can the driver be arrested?
Show answer
Answer C: Yes, driving while impaired by alcohol is an offense at any concentration
The per se figure, 0.08 percent in most states and 0.05 percent in Utah, is the level at which impairment is presumed. Impairment shown by driving behavior and field tests is enough on its own, because alcohol affects skills well before that number.
-
5. When is a driver or rider most likely to need hand and arm signals instead of the vehicle turn signal lamps?
Show answer
Answer D: When the lamps have failed or cannot be seen because of glare or a load
Hand and arm signals replace or reinforce the lamps whenever the lamps do not work or cannot be seen clearly by other road users.
-
6. At what tread depth should a tire be replaced?
Show answer
Answer A: When the tread is worn down to 2/32 of an inch
At that depth a tire loses grip quickly, especially on wet roads, and the built in wear bars or the penny test both show when the point has been reached.
-
7. How can you tell a tire has reached its wear limit without measuring it?
Show answer
Answer C: The wear bars across the grooves become level with the tread
Molded bars sit at the bottom of the grooves. Once the surrounding tread has worn down to them, the tire has reached the end of its safe life.
-
8. After an hour on a hot highway your tire pressure reads higher than it did in the morning. What should you do?
Show answer
Answer D: Nothing, because pressure rises when tires heat up
Air expands as the tire warms, so a hot reading is normally above the cold setting. Bleeding air off would leave the tire underinflated once it cooled.
-
9. What does a first conviction in five years for drag racing or reckless stunt driving cost a Georgia driver?
Show answer
Answer C: A 12-month suspension, with reinstatement possible after 120 days
Georgia suspends the license for twelve months on a first drag racing conviction within five years, with reinstatement possible after 120 days.
-
10. In which crash must the police always be notified?
Show answer
Answer D: Any crash in which somebody has been injured or killed, whatever the damage
Injury or death always makes a crash reportable, whatever the amount of vehicle damage or the opinions of the drivers.
-
11. Why does a heavier vehicle need more room to stop than a light one from the same speed?
Show answer
Answer B: Because there is more mass in motion for the tires to slow down
More mass means more energy at the same speed, and the brakes and tires need more distance to get rid of it.
-
12. You are driving on a road covered with a layer of wet fallen leaves. What should you expect?
Show answer
Answer B: As little grip as on ice, plus hidden markings and hidden holes
Wet leaves are as slippery as ice and they hide the lane lines and any potholes underneath, so slow well before curves and stops.
-
13. The driver ahead of you is straddling the lane line and is not signaling. How should you respond?
Show answer
Answer B: Stay back until you can see which lane that driver will take
A vehicle astride the line could move either way, so the only safe place is behind it where both possibilities are still covered.
-
14. You are circulating in the inner lane of a two-lane roundabout, your exit is next, and a vehicle is beside you in the outer lane. What should you do?
Show answer
Answer C: Keep circulating around the island and take that same exit on your next time around
You may not cut across a vehicle in the outer lane; if you cannot exit safely, continue around the circle and try again.
-
15. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
16. Two vehicles meet on a steep, narrow mountain road with no room to pass. Which driver should back up?
Show answer
Answer C: The driver heading downhill, who has more control while reversing
On a narrow mountain road the vehicle facing downhill yields, because backing uphill gives better control than reversing down a grade.
-
17. You arrive at an intersection where the traffic signal is completely dark because of a power failure. How should you proceed?
Show answer
Answer C: Treat the intersection as an all-way stop
When a signal shows no indication at all, drivers on every approach must stop and then take turns, exactly as at an all-way stop.
-
18. Why is repeatedly changing lanes to work through heavy traffic a poor idea?
Show answer
Answer A: It raises the crash risk and saves almost no time
Each lane change adds a conflict with another vehicle, and in congestion the lanes move at similar average speeds, so the gain is negligible.
-
19. When is a Georgia driver declared a Habitual Violator?
Show answer
Answer B: On a third conviction of certain listed offenses within five years
Georgia revokes the license of a driver declared a Habitual Violator, which follows a third conviction from a defined list of offenses inside a five-year window.
-
20. Where among these is parking specifically prohibited?
Show answer
Answer A: On a bridge, in a tunnel or on railroad tracks
Bridges and tunnels have no safe refuge and cannot be widened, and a vehicle left on railroad tracks cannot be avoided by an approaching train.
-
21. Why should the washer reservoir hold proper washer fluid rather than plain water in winter?
Show answer
Answer D: Water freezes and it leaves you with no way at all to clean the glass
Washer fluid contains antifreeze, so it still works in the cold, whereas water freezes in the reservoir and the lines.
-
22. Is it acceptable to watch a video on a screen positioned where you can see it while driving?
Show answer
Answer B: No, the screen pulls your eyes and attention away from the road
Moving pictures are among the strongest visual distractions. Video screens must be out of the driver's view while the vehicle is moving.
-
23. You are using the parking brake to slow a vehicle whose brakes have failed. How should you apply it?
Show answer
Answer D: Gradually, holding the release so you can let it off if the rear slides
The parking brake works on two wheels only, so applying it hard can lock them and spin the vehicle. Keep the release held so you can back it off instantly.
-
24. You are in a passing zone that continues over the crest of a hill ahead. May you start a pass?
Show answer
Answer B: Only if you can finish it well before the crest
Beyond the crest you cannot see oncoming traffic, so any part of the pass that happens there is being made blind.
-
25. A tractor-trailer is backing slowly across the roadway to enter a loading dock. What should you do?
Show answer
Answer C: Stop and wait until the truck has finished the maneuver
A backing truck driver has a very limited view and the trailer can swing unexpectedly. Trying to squeeze past in either direction risks being crushed.
-
26. Which vehicles are excepted from Georgia's child restraint requirement?
Show answer
Answer A: Taxicabs and public transit vehicles
Georgia's child restraint requirement applies to every driver carrying a child under eight except in a taxicab or a public transit vehicle.
-
27. The sun is low behind you and shining into the eyes of oncoming drivers. What should you do?
Show answer
Answer C: Turn on your headlights and expect oncoming drivers not to see you
Drivers facing the low sun may not see you at all, so make yourself as visible as possible and give way rather than insisting on your right of way.
-
28. When is passing another vehicle on the right generally permitted?
Show answer
Answer C: When the road has two or more lanes in your direction, or the vehicle ahead is turning left and there is room without leaving the pavement
Passing on the right is limited to situations where a lawful lane exists for it or the vehicle ahead is turning left, and it may never be done by driving onto the shoulder.
-
29. Some states allow a left turn against a red light. Which movement is it?
Show answer
Answer A: A left turn from a one-way street onto another one-way street
The movement generally allowed on red is one-way to one-way, because the turn does not cross any lane of oncoming traffic; a few states also extend it to a two-way street turning onto a one-way street.
-
30. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
31. You reach a T intersection where the cross street has a ONE WAY sign pointing to the right. What may you do?
Show answer
Answer B: Turn right only, because the street carries traffic in that direction
The arrow shows the only direction traffic may travel, so the only legal movement from the terminating road is a right turn.
-
32. Why is an underinflated tire especially risky on a long drive in hot weather?
Show answer
Answer C: It flexes more, builds up heat and can fail at speed
A soft tire flexes on every rotation, and that flexing makes heat that the hot road and high speed add to until the tire can come apart.
-
33. A driver sees this sign on a quiet road with no other traffic in either direction. What is the correct response?
Show answer
Answer C: Slow down, look and listen for a train, and be ready to stop
The sign gives advance notice of a highway-rail grade crossing, so the driver reduces speed, checks both directions along the tracks and keeps enough room to stop short of the rails.
-
34. A driver passes this sign and the signal beyond it is already showing green. What is the safest response?
Show answer
Answer C: Ease off the accelerator and be ready to stop, because an indication that has been showing for a while is about to change
A signal that has been displaying the same indication for some time is close to changing, so arriving at a controlled speed with the brake covered is safer than accelerating to beat it.
-
35. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
36. At an intersection that uses a lagging left turn, when is the left-turn arrow displayed?
Show answer
Answer B: After the through movement has run
A lagging left turn phase runs at the end of the green rather than the start, so a driver waiting to turn should not assume the arrow has been missed.
-
37. How old must the responsible adult who signs a Georgia minor's application be?
Show answer
Answer A: At least 18 years old
Georgia requires the responsible adult who signs for a minor to be at least 18; that person may be a parent, guardian, certified instructor, social worker or shelter employee.
-
38. Why would a restriction like this one be applied to a stretch of road?
Show answer
Answer A: Because there is not enough visible road ahead to complete a pass safely
Limits on overtaking are set where a hill, a curve or an obstruction leaves too little sight distance for a driver to pull out, pass and return before meeting oncoming traffic.
-
39. What penalty does Georgia attach to driving so slowly that it impedes the normal movement of traffic?
Show answer
Answer B: A fine of up to $1,000 and three points on the driving record
Georgia punishes impeding traffic with a fine of up to $1,000 and three points, except where the reduced speed is necessary for safe operation.
-
40. You are traveling at 55 mph and see a vehicle ahead moving at about 15 mph. What is the hazard?
Show answer
Answer A: You reach it far sooner than you expect
At a 40 mph difference you cover the gap in a few seconds, which is why drivers strike slow vehicles they saw in plenty of time.
