1. 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.
-
2. 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.
-
3. A deer has just crossed in front of you on a stretch signed for animal crossings. What is the best assumption?
Show answer
Answer B: More animals are likely to follow the first one
Deer travel in groups, so one animal crossing usually means others are about to follow, and a driver should slow and keep scanning both shoulders.
-
4. You are stopped at a stop sign on a two-way stop intersection and the cross street has no stop signs at all. What does that mean for you?
Show answer
Answer A: You yield to all cross traffic no matter how long that takes
At a two-way stop only your direction is controlled, so there is no taking turns; you wait for a gap big enough to enter safely.
-
5. 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.
-
6. Why does this warning matter more on a motorcycle than in a car?
Show answer
Answer B: Because a sudden jolt can unsettle a two-wheeled machine and the rider can lose control
A jolt can push a motorcycle off line or lift a wheel, so a rider slows early, comes slightly off the seat and keeps a relaxed but firm hold on the handlebars.
-
7. Which of these would appear as a symbol on a blue general service sign?
Show answer
Answer A: A hospital
General service signs cover facilities such as hospitals, fuel, food, lodging, camping, telephones and rest areas, all shown in white on blue.
-
8. Apart from a crash causing death or serious injury, what else removes a Louisiana driver's option to refuse a chemical test?
Show answer
Answer D: Having refused on two previous and separate occasions
A driver who has already refused testing on two previous and separate occasions may not lawfully refuse again.
-
9. You get into a heated argument with a passenger while driving. What should you do?
Show answer
Answer D: End the discussion or pull over to finish it
Anger narrows attention and encourages risk, and a conversation you cannot let go of is a passenger you should be parked to talk with.
-
10. You realize you have driven several miles without remembering any of it. What kind of distraction is this?
Show answer
Answer C: Cognitive distraction, because your mind was not on driving
Daydreaming or being lost in thought is a cognitive distraction. Your eyes may be on the road, but your brain is not processing what they see.
-
11. Where should a rear-facing infant seat never be placed?
Show answer
Answer C: In a front seat with an active passenger air bag
A deploying front air bag strikes the back of a rear-facing seat with enormous force. Rear-facing seats belong in the back seat.
-
12. At night you are waiting to turn left and can see only the headlights of an approaching vehicle. Why should you allow a bigger margin?
Show answer
Answer D: Because lights alone make speed and distance hard to judge
With no other visual cues, two points of light give you very little information about how fast the vehicle is closing, so leave extra margin.
-
13. What ceiling does Louisiana's general traffic penalty section set for a second or later offense?
Show answer
Answer D: Up to 500 dollars or 90 days
For a second or later traffic offense Louisiana raises the ceiling to a fine of 500 dollars or 90 days of imprisonment, or both.
-
14. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
15. Your headlights suddenly go out while you are driving at night. What should you do?
Show answer
Answer A: Try the dimmer switch and the headlight switch, turn on the hazard lights and pull off the road
Switching between high and low beams or cycling the light switch sometimes restores the lights. If not, use the hazard and parking lights to get off the road safely.
-
16. Why do young drivers carrying several friends face a higher crash risk?
Show answer
Answer D: Because young passengers are a strong source of distraction and pressure
Crash risk for new drivers rises with each extra young passenger, mainly through distraction and social pressure.
-
17. 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.
-
18. An overhead sign shows that the right lane is EXIT ONLY. What does that mean if you intend to stay on the highway?
Show answer
Answer B: You have to move out of that lane before the exit
An exit only lane leaves the highway completely, so a driver continuing on the highway has to change lanes before it does.
-
19. What should you avoid when a hostile driver pulls alongside you?
Show answer
Answer A: Making eye contact, or answering the gestures in any way at all
Any response, including a look, encourages an aggressive driver, so give none and let the vehicle go.
-
20. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
-
21. You are approaching the crest of a hill and cannot see the road beyond it. What should you do?
Show answer
Answer C: Slow down and keep well to the right
Beyond a blind crest there may be a stopped vehicle, a cyclist or an oncoming driver crossing the center line, so reduce speed and hold your own side.
-
22. Where should you be looking as you back into a parallel parking space?
Show answer
Answer B: Over your shoulder through the rear window, glancing all around
Mirrors and cameras leave blind areas, so turn and look through the rear window while checking the front of your car and both sides as it swings.
-
23. The light ahead is green but traffic beyond the intersection is backed up. What should you do?
Show answer
Answer B: Wait behind the intersection until there is room to clear it completely
You may not enter an intersection unless you can get completely through it, because stopping inside blocks cross traffic when the signal changes.
-
24. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
25. What is the maximum fine for possessing an open alcoholic beverage container in the passenger area of a vehicle in Louisiana?
Show answer
Answer B: 100 dollars
Louisiana caps the open container fine at 100 dollars plus court costs, and the violation may not be entered on the driving record.
-
26. 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.
-
27. An oncoming driver flashes their headlights while you are waiting to turn left. What should you do?
Show answer
Answer D: Judge the situation yourself, since the flash may mean something else
A flash is not a legal signal and may mean many things, so the decision to turn stays yours and must be based on what you can see.
-
28. 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.
-
29. What is the fine for a first safety belt offense in Louisiana?
Show answer
Answer C: 50 dollars, including all costs of court
A first safety belt conviction in Louisiana costs 50 dollars inclusive of court costs; a second or later one costs 75 dollars, and Orleans Parish adds a further 20 dollars.
-
30. The light ahead is green, but traffic beyond the intersection is backed up so far that you could not clear it. What is the correct action?
Show answer
Answer D: Wait behind the stop line until there is room on the far side
Entering an intersection you cannot clear blocks cross traffic and pedestrians, so you should hold your position until space opens on the other side.
-
31. Two people drink the same amount of alcohol at the same time. Why might their blood alcohol concentrations differ?
Show answer
Answer C: Body weight, gender and food in the stomach affect the concentration
Smaller people and, on average, women reach higher concentrations from the same amount of alcohol, and an empty stomach speeds absorption. Counting drinks alone does not tell you your level.
-
32. You are on an entrance ramp merging onto a freeway. Who has to give way?
Show answer
Answer B: You must yield and fit into a gap in the traffic already on the freeway
Traffic entering a highway must yield to traffic already on it. Use the acceleration lane to match speed and merge into a gap.
-
33. Why is this restriction used so often on a divided road just before a crest or a bend?
Show answer
Answer A: Because a vehicle turning across the median there stays hidden from approaching drivers until it is too late
The maneuver needs a long gap and good visibility, and where sight distance is short an approaching driver has no time to react to a vehicle turning across the road.
-
34. The divided highway ends warning sign means that
Show answer
Answer D: the median separating the directions ends and the road returns to two-way operation
Beyond this sign opposing traffic is no longer separated by a median, so the driver must keep right and expect vehicles approaching in the adjacent lane.
-
35. You have a green left-turn arrow but a pedestrian is still walking in the crosswalk you must cross. What should you do?
Show answer
Answer B: Wait until the crosswalk is clear before turning
A green arrow protects you from other vehicles, but it never removes the duty to yield to a person already in the crosswalk.
-
36. Reaching for a drink in the cup holder is which kind of distraction?
Show answer
Answer A: Manual and visual at the same time
Your hand leaves the wheel and your eyes flick down to find the cup, so a task that feels trivial takes away two of the three things driving needs.
-
37. When is switching traction control off sometimes useful?
Show answer
Answer A: When you need spinning wheels to rock out of deep snow or mud
Rocking a stuck vehicle free needs the wheel spin that the system normally prevents. Switch it back on as soon as you are moving again.
-
38. A separate right-turn lane leads onto the cross street and carries a yield sign. What does it require?
Show answer
Answer D: Slowing and giving way to traffic and people, stopping if needed
A yield requires you to slow, give way to traffic in the lane you are joining and to pedestrians, and stop only if that is what safety demands.
-
39. How do stimulant drugs such as amphetamines or cocaine typically affect driving?
Show answer
Answer D: They can make the driver overconfident and more willing to take risks
Stimulants create a false sense of alertness and encourage aggressive, risky driving. When they wear off, sudden fatigue can follow.
-
40. How should a head restraint be adjusted?
Show answer
Answer D: So the top is at least as high as the back of your head and close behind it
A restraint set at head height and close behind limits how far the head snaps backward in a rear impact, which is what reduces neck injury.
