1. Your vehicle has a blind spot warning light in the door mirror. What should that mean for your habits?
Show answer
Answer B: You still check the blind spot yourself, because the system can miss a rider
Blind spot systems are an aid, not a substitute, and a motorcycle or a bicycle can be missed or arrive faster than the sensor expects.
-
2. What happens when alcohol is combined with another drug that also affects the nervous system?
Show answer
Answer B: Impairment is often far greater than either one alone would produce
Combined substances can multiply each other's effects, producing impairment well beyond what a driver would expect from either one taken separately.
-
3. Alcohol is classified as which kind of drug?
Show answer
Answer B: A depressant that slows the central nervous system
As a depressant, alcohol slows the brain and nervous system, which lengthens reaction time and dulls the coordination that driving depends on.
-
4. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
5. On an unlit road, about how far ahead do high beams normally let you see?
Show answer
Answer D: About 350 to 500 feet ahead of the vehicle
High beams light roughly 350 to 500 feet of road and low beams far less, which is why night speeds have to be chosen around the beam, not the limit.
-
6. Your right-turn lane shows a green arrow while the through lanes face a red ball. What does that mean?
Show answer
Answer C: Only the right turn is allowed, and it is protected while the arrow lasts
A green arrow gives a protected movement in that direction only; the red ball still stops the through traffic in the other lanes.
-
7. You realize you have turned the wrong way onto a one-way street. What should you do?
Show answer
Answer A: Pull to the right, stop, and back into the street you came from when clear
Get out of the traffic stream first: pull right and stop, then back out into the street you came from once you can see it is safe.
-
8. What is wrong with slowing to a crawl at a stop sign and then rolling on through?
Show answer
Answer C: It is not a stop, and you may miss a pedestrian or cross traffic
A rolling stop is a violation and it also cuts short the moment you need in order to look carefully in each direction before entering.
-
9. You feel drowsy, so you open a window and turn the radio up. What does that achieve?
Show answer
Answer B: Very little, because the drowsiness comes back
Cold air and loud music are not sleep, so the alerting effect lasts a minute or two and the driver is soon just as sleepy and closer to a lapse.
-
10. A preferential lane sign reads HOV 2+ and lists the hours it applies. During those hours, which vehicles may use the lane?
Show answer
Answer A: Vehicles carrying at least two people, counting the driver
The number on an HOV sign is the minimum number of occupants, driver included, that a vehicle must carry to use the lane while the restriction is in effect.
-
11. What happens when tires are driven underinflated for a long time?
Show answer
Answer D: They wear at the edges, they run hot and they are more likely to fail
An underinflated tire flexes too much, which wears the shoulders and builds up heat that can destroy the tire.
-
12. You are overtaking in a short passing lane on a two-lane road and it is about to end. What must you do?
Show answer
Answer A: Finish the pass and move back to the right before it ends
The added lane ends and the traffic returns to a single lane in each direction, so the pass has to be complete before the pavement runs out.
-
13. An overhead lane-use control signal shows a steady red X above your lane. What does it mean?
Show answer
Answer B: You may not use that lane and must move out of it
A steady red X means the lane below it is closed to you, while a steady yellow X is the warning to prepare to vacate the lane and a downward green arrow means the lane is open.
-
14. You are approaching a marked school crossing and children have started to cross the roadway. What is required?
Show answer
Answer A: Stop and let the children finish crossing the roadway
Drivers give way to people in a marked crossing, stopping if that is what it takes, and children in particular may change direction without warning.
-
15. Your light turns green and a driver on the cross street enters against a red. What should you do?
Show answer
Answer D: Hold back and let that vehicle go through
Giving up a right of way you are entitled to is the only way to avoid a crash with a driver who has already failed to yield.
-
16. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
17. Why is standing water across a road dangerous even when it looks shallow?
Show answer
Answer B: It can hide a washed out roadbed, a deep hole or a missing cover
You cannot see the surface under the water, and floods commonly wash the roadbed away or lift covers off drains.
-
18. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
19. What happens to a Georgia driver under 21 who is convicted of a single 4-point violation?
Show answer
Answer D: The license is suspended
Georgia suspends the license of any driver under 21 who is convicted of any violation worth four points, without waiting for a point total to build up.
-
20. Within what distance of a railroad crossing, bridge or tunnel does Georgia forbid passing?
Show answer
Answer B: 100 feet
Georgia prohibits passing within 100 feet of a railroad crossing, a bridge or a tunnel.
-
21. When should you enter a destination into a navigation device?
Show answer
Answer B: Before you start driving, or after parking in a safe place
Programming a route is a visual, manual and mental task at the same time, so it belongs to the moments before the vehicle moves rather than to any point in traffic.
-
22. An exit ramp is separated from the highway by a triangle of pavement painted with white stripes. What may you do there?
Show answer
Answer C: Nothing; keep off it and choose either the lane or the ramp
The striped area between a ramp and the through lanes is not for driving, stopping or last-second changes of direction.
-
23. 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.
-
24. You are slowing to turn right at an intersection and a bicyclist is riding beside your right side in a bike lane. What should you do?
Show answer
Answer D: Let the bicyclist go through the intersection before you begin the turn
Turning across the path of a bicyclist who is going straight causes the classic right-hook crash. The rider continuing straight has the right-of-way over your turn.
-
25. Which trailer lights must work before you drive away?
Show answer
Answer B: The tail lights, brake lights and turn signals
The trailer hides the vehicle lights from anyone behind, so its own tail, brake and turn signals have to work before you move.
-
26. You are on a four-lane divided highway and a vehicle in your lane is stopped waiting to turn left across the median. What is the normal way past?
Show answer
Answer D: Slow down and go by in the lane to the right when it is clear
On a multilane road the free lane beside you is the lawful place to go past a vehicle waiting to turn, and the median is not part of the roadway.
-
27. As speed rises, which part of the total stopping distance grows the fastest?
Show answer
Answer B: The braking distance, which grows far faster than speed itself
Perception and reaction distances grow in step with speed, but braking distance grows roughly with the square of speed, so it dominates at higher speeds.
-
28. 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.
-
29. Two solid white lines separate your lane from the lane beside it. What do they mean?
Show answer
Answer B: Crossing from one lane to the other is prohibited
A solid double white line marks a boundary that road users may not cross, such as the entrance to a preferential lane.
-
30. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
31. What did the Teenage and Adult Driver Responsibility Act create in Georgia, and whom does it cover?
Show answer
Answer D: A graduated licensing program for teens aged 15 to 18
TADRA, enacted in 1997, established Georgia's three-step graduated driver licensing program for drivers aged 15 to 18.
-
32. You are making a legal U-turn at an intersection. Who has the right of way?
Show answer
Answer C: Everyone else, until your turn is complete
A U-turn crosses several paths at once, so you yield to oncoming vehicles, to crossing traffic and to pedestrians before starting it.
-
33. You are traveling in the same direction as a funeral procession and want to get ahead of it. What should you not do?
Show answer
Answer B: Driving in between the vehicles of the procession
Most states prohibit driving into or through a funeral procession, and cutting into the line leaves the drivers behind with no lead vehicle to follow, so go around only where passing is permitted.
-
34. You are entering an angle parking space on your right. What should you do?
Show answer
Answer C: Stay a little left of the space, then turn in between the lines
Keeping a little left of the space gives the front wheels the room to turn in cleanly and leaves your car centered between the lines.
-
35. You are turning left at an intersection just beyond the crest of a hill. What is the added risk?
Show answer
Answer B: Oncoming vehicles appear with very little warning and close quickly
A crest hides approaching traffic until it is close, so the gap you thought was empty can fill in the time the turn takes.
-
36. You leave a brightly lit service area onto a dark rural road. Why should you slow down for a while?
Show answer
Answer C: Your eyes need time to adjust, so at first you see less
Eyes take a few minutes to adapt from bright light to darkness, and during that time you can see much less than your headlights actually show.
-
37. Another driver takes a right of way that was legally yours. What should you do?
Show answer
Answer A: Give way to the other driver and avoid the crash, whatever the law says
Right of way is something you give, not something you take, and being in the right is no protection in a collision.
-
38. What is the minimum vision Georgia accepts for a noncommercial driver's license?
Show answer
Answer B: 20/60 in one eye, with or without corrective lenses, and a horizontal field of at least 140 degrees
Georgia requires 20/60 in at least one eye, corrected or uncorrected, together with a horizontal field of vision of at least 140 degrees.
-
39. The trailer you are towing begins to sway from side to side at highway speed. What should you do?
Show answer
Answer D: Ease off the accelerator, hold the wheel steady and let the speed drop
Sway grows with speed and with sudden inputs. Reducing speed gently while keeping the steering steady lets the trailer settle behind you.
-
40. Warning signs such as stop ahead, yield ahead and signal ahead are installed mainly where
Show answer
Answer B: the traffic control device cannot be seen from far enough away
These advance warning signs are used when a crest, curve or obstruction keeps the stop sign, yield sign or signal from coming into view in time for a driver to react.
