1. At roughly what speed can hydroplaning begin when a lot of water is lying on the road?
Show answer
Answer C: At speeds as low as about 35 mph
With enough water and less than perfect tread, a tire can start to ride on the water at around 35 mph, well below normal highway speeds.
-
2. Freeway traffic ahead of you has come to a stop. Besides braking early, how can you warn the drivers behind you?
Show answer
Answer B: By switching on the hazard lights for a few seconds
A short burst of hazard lights is a recognized way to tell following traffic that the queue ahead has stopped, and it carries much further back than brake lights. Some states restrict hazard lights on a moving vehicle, so use them only for the moment you are slowing.
-
3. A crash happens directly in front of you and vehicles are blocking both lanes. What should you do?
Show answer
Answer B: Stop at a safe distance, put on the hazards and warn the traffic behind
The greatest danger after a crash is a second collision, so stop short of it and make sure the traffic behind you can see the problem.
-
4. A traffic signal is displaying a flashing red light. How must you treat it?
Show answer
Answer D: Stop completely, then proceed when the way is clear
A flashing red carries the same meaning as a stop sign: come to a full stop, then go only when it is safe.
-
5. How many alcoholic drinks does it take to begin affecting driving ability?
Show answer
Answer C: Even one drink can affect it
A single drink can slow reactions and weaken judgment before you feel any change. Impairment starts long before a person feels drunk.
-
6. You are on a city street with two lanes in your direction, cars parked along the curb and driveways every few yards. Which lane is usually safer?
Show answer
Answer B: The lane farther from the curb, away from opening doors and vehicles pulling out
Most of the hazards on such a street come from the curb side, so the inside lane gives you more space and more time to react.
-
7. A wide crosswalk you are turning across has a refuge island in the middle. What should you assume about people standing on it?
Show answer
Answer D: They may step off the island into your path at any moment
An island is a pause in a crossing, not the end of one, so treat anyone on it as a pedestrian who is still crossing.
-
8. 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.
-
9. You are turning left from a two-way street onto another two-way street. Where should you begin and end the turn?
Show answer
Answer B: Begin in the lane just right of the center line and finish just right of the center line of the new street
You approach a left turn from the lane closest to the center line and enter the new roadway just to the right of its center line, which keeps you clear of oncoming traffic.
-
10. You carry reflective warning triangles in your car. How should they be used after a breakdown?
Show answer
Answer B: Set out behind the vehicle, far enough back to warn traffic before it arrives
A warning device works only if drivers see it in time to react, so it is placed well back along the road they are traveling.
-
11. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
12. How should speed and following distance be adjusted beyond this sign?
Show answer
Answer D: Cut speed and leave a longer gap, because traffic can stop without warning
Traffic in these areas stops and starts unexpectedly and there is little room to steer around a problem, so extra space is what prevents a rear-end collision.
-
13. What do two solid yellow lines down the middle of a two-way road mean?
Show answer
Answer D: Passing is prohibited for traffic in both directions
A double solid yellow line marks a two-direction no-passing zone, so neither direction may cross it to overtake another vehicle.
-
14. Your vehicle has daytime running lights. Why should you still switch on the headlights at dusk?
Show answer
Answer B: Daytime running lights usually do not light the tail lights, so you are hard to see from behind
On many vehicles the daytime running lights illuminate only the front. Without the headlight switch on, the rear of the vehicle stays dark and the dash may still look lit.
-
15. What makes up the total distance needed to bring a vehicle to a stop?
Show answer
Answer A: The distance covered while you perceive the hazard, the distance covered while you react, and the braking distance
Total stopping distance combines the ground covered while you notice the hazard, the ground covered while you move your foot to the brake, and the ground covered while the brakes slow the vehicle.
-
16. How do you avoid the sharp nod at the end of a stop?
Show answer
Answer A: Ease the pedal pressure off slightly just before the vehicle stops
The nod comes from the suspension unloading at the instant the wheels stop. Releasing a little pressure at the end lets the vehicle settle smoothly.
-
17. You are approaching a multilane roundabout. When should you choose your lane?
Show answer
Answer C: Before you enter, using the lane-choice sign on the approach
You select your lane on the approach the way you would at any multilane intersection, then stay in that lane all the way around, because changing lanes inside a roundabout creates side-impact conflicts.
-
18. Why should you not leave the engine running when you walk away from your vehicle?
Show answer
Answer C: Because the vehicle can be stolen or can move on its own
An unattended running vehicle is an easy theft and, if the transmission slips or is knocked out of park, it can roll away with nobody at the wheel.
-
19. The signal ahead turns yellow while you are approaching it. What does the yellow light mean?
Show answer
Answer C: The red is coming; stop if you can do so safely
A steady yellow warns that the red is next. Stop if you can do so safely; enter the intersection only when stopping would be dangerous.
-
20. A flashing red arrow is displayed for your turning lane. What does it require?
Show answer
Answer D: Stopping, then turning when the way is clear
A flashing red arrow is treated like a stop sign for that movement: come to a full stop, then turn when it is safe and no one has to be cut off.
-
21. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
22. Apart from other vehicles, who else must a driver let go first at this sign?
Show answer
Answer A: Pedestrians and cyclists already in or entering the crossing
The duty to give way covers every road user who has the right of way at that point, including people walking or cycling across the driver's path.
-
23. You want to turn left at an intersection with no signs or signals and a vehicle is coming straight toward you from the opposite direction. What must you do?
Show answer
Answer C: Yield and turn after the oncoming vehicle has passed
A driver turning left always gives way to oncoming traffic that is close enough to be a hazard, whether or not the intersection is controlled.
-
24. A lane along the right edge is set off by a solid white line and marked with a bicycle symbol. How should a driver treat it?
Show answer
Answer B: Stay out of it except for the short distance needed to turn or cross where that is allowed
A marked bicycle lane is set aside for bicycle traffic, and motor vehicles may enter it only briefly where turning or crossing is permitted.
-
25. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?
Show answer
Answer D: Slow or stop and let the person reach safety
Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.
-
26. A driver is thinking about overtaking a slower vehicle and sees this sign a short distance ahead. What does it mean for that pass?
Show answer
Answer B: The pass must be finished before the restricted section begins
The sign marks the start of a section where passing is prohibited, so a driver may not be on the left side of the road beyond it; any pass has to be completed before that point or not started at all.
-
27. In a work zone a flagger signals you to stop, but the sign beside the road says the lane is open. What should you do?
Show answer
Answer C: Obey the flagger
A flagger controls the work zone in real time and the instruction outranks the signs and markings, which cannot reflect what is happening at that moment.
-
28. The lane you are in has a right-turn-only arrow painted on the pavement. What must you do?
Show answer
Answer C: Turn right, because a lane-use arrow is a legal requirement
Lane-use arrows painted on the pavement are regulatory markings, so a driver in that lane must travel in the direction shown.
-
29. A driver ahead brakes for no reason you can see, again and again. What should you do?
Show answer
Answer B: Increase your following distance and be ready for yet another stop
Unexplained braking tells you the driver is unsure or distracted, so the safe answer is more room, not less.
-
30. How does alcohol typically affect a driver's vision?
Show answer
Answer D: It blurs vision, weakens night vision and narrows attention to the sides
Alcohol slows the eye muscles and the brain's processing of what is seen, degrading focus, night vision, depth perception and awareness of movement at the edges of the field of view.
-
31. The steering suddenly becomes very heavy while you are driving. What has happened and what should you do?
Show answer
Answer C: The power steering has failed, so steer with more effort and pull over
Loss of power assistance leaves the steering usable but very heavy. Keep both hands on the wheel, slow gradually and pull off the road to check it.
-
32. Which children must ride in a child passenger restraining system in Georgia?
Show answer
Answer D: Every child under eight, in a system suited to height and weight
Georgia requires a driver carrying a child under eight to use a child passenger restraining system appropriate to that child's height and weight and meeting Federal Motor Vehicle Safety Standard 213.
-
33. How does a full load of passengers and luggage affect your braking?
Show answer
Answer B: It lengthens the stopping distance, so you should brake earlier
More weight means more energy to get rid of, so a loaded vehicle takes longer to stop and needs earlier, gentler braking.
-
34. A driver's destination lies along the street to the right, and this sign stands at that corner. How should the driver reach it?
Show answer
Answer D: By going on and using a later intersection where turning is allowed
When a movement is barred at one corner the driver has to reroute, normally by continuing and coming back to the destination from a permitted approach.
-
35. How much clear road do driver manuals say you need before starting a pass at highway speed on a two-lane road?
Show answer
Answer C: Enough to complete the pass and return, roughly ten to twelve seconds of travel
At highway speed the whole maneuver of pulling out, overtaking and returning takes roughly ten to twelve seconds, and every foot of that has to be visible before you start.
-
36. What does a blood alcohol concentration of 0.08 mean for the driver of a car?
Show answer
Answer B: It is the level almost every state treats as legally intoxicated
In almost every state a driver at 0.08 or above is legally intoxicated whatever the driver seems like, but impairment starts well before that level is reached.
-
37. A diamond-shaped sign is used to
Show answer
Answer A: warn of a condition on or next to the road that may call for caution
The diamond is the standard shape of the warning series, which alerts drivers to conditions that would otherwise not be obvious in time to react.
-
38. 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.
-
39. What do yellow lines painted on a roadway separate?
Show answer
Answer D: Traffic moving in opposite directions
Yellow markings separate opposing streams of traffic, and they also mark the left edge of a divided highway or a one-way roadway.
-
40. A small yellow plaque showing a speed number below a curve warning sign gives
Show answer
Answer C: the speed recommended for the condition being warned about
The advisory speed plaque belongs to the warning series and states the speed judged safe for the condition ahead under good circumstances, not a regulatory limit.
