1. What speed does Louisiana law set for a multi-lane divided highway that has partial or no control of access?
Show answer
Answer C: 65 miles per hour
Louisiana places a multi-lane divided highway with partial or no control of access at 65 miles per hour, between the ordinary highway figure and the interstate figure.
-
2. A center lane is marked with a broken yellow line on each side and is controlled by overhead lane signals. How is that lane used?
Show answer
Answer A: It carries traffic one way or the other according to the signals
A reversible lane is marked with broken yellow lines on both sides and its direction of travel is set by the lane control signals above it.
-
3. How does heavy cargo on a roof rack change the way a vehicle handles?
Show answer
Answer D: It raises the center of gravity, so the vehicle tips more in turns and needs gentler steering
Weight carried high makes the vehicle lean more and roll over more easily, and extra weight lengthens stopping distance. Drive slower and steer smoothly with a loaded roof.
-
4. A steady green arrow pointing left is displayed for your turning lane. What does it tell you?
Show answer
Answer D: The turn is protected because conflicting traffic is being held
A steady green arrow gives a protected movement in the direction shown, although you still yield to pedestrians and to any vehicle already inside the intersection.
-
5. You are behind a snow plow working on a highway. What is the correct way to drive?
Show answer
Answer C: Stay well back and do not try to pass it
A plow throws snow, runs wider than its body and works on the poor surface ahead of it, so the cleared road behind it is the safest place to be.
-
6. On an undivided two-lane road you meet a school bus coming toward you with its red lights flashing and its stop arm out. What must you do?
Show answer
Answer C: Stop and wait until the red lights stop flashing
On an undivided road drivers in both directions must stop for a school bus loading or unloading, because children may cross in front of it.
-
7. In near freezing weather, which part of an otherwise clear road is most likely to still be icy?
Show answer
Answer D: A shaded dip under trees or beside a rock cut
Sun clears most of the road, but shaded hollows never warm up and can hold ice long after the rest of the pavement is dry.
-
8. You have a green light and are turning right. Pedestrians are stepping off the curb into the crosswalk you are about to cross. What should you do?
Show answer
Answer B: Wait and let them cross before completing your turn
A green light does not release a turning driver from yielding to pedestrians already in the crosswalk of the street being entered.
-
9. You are driving in fog so thick that you can barely see the vehicle ahead. Which pavement marking is the best guide for staying in your lane?
Show answer
Answer A: The white edge line on the right side of the road
The right edge line keeps you positioned away from oncoming traffic and is easy to follow at low speed. Following tail lights closely tempts you to drive faster than you can see.
-
10. The vehicle you have borrowed is larger and heavier than your own. How should you drive it?
Show answer
Answer B: Allow more room for stopping and for turns until you are used to it
Extra weight and length mean longer stopping distances and wider turns, so give yourself more room until you are used to it.
-
11. What does a marked crosswalk tell a driver approaching a corner?
Show answer
Answer D: Where pedestrians are expected to cross and must be given way
Crosswalk markings show pedestrians where to cross and warn drivers to yield to anyone using the crossing.
-
12. You reach a one-lane bridge and a vehicle is already partway across it coming toward you. What should you do?
Show answer
Answer D: Stop before the bridge and let it come through
A vehicle already on a one-lane bridge has the right of way, and the driver who has not yet entered waits at the approach.
-
13. It is dark, it is raining and you are towing a trailer. How should you set your following gap?
Show answer
Answer B: Add extra seconds for each condition, well beyond three
Each factor that lengthens your stopping distance or shortens your view calls for another second or more, and they add up when several occur together.
-
14. Why is a U-turn on a one-way street a problem?
Show answer
Answer A: You would end up facing the wrong way against all the traffic
Every lane of a one-way street runs the same way, so turning around leaves you driving head-on against all of the traffic.
-
15. Why are drivers required to turn the front wheels when parking on a grade?
Show answer
Answer A: So that a vehicle that starts to roll leaves the traffic lanes instead of entering them
The wheel position is a last line of defense if the parking brake or transmission fails, directing the vehicle into the curb or off the roadway.
-
16. What must you do before changing lanes, in addition to signaling and checking your mirrors?
Show answer
Answer D: Glance over your shoulder to check the blind spot the mirrors do not cover
Mirrors leave an area beside and behind the vehicle that they cannot show, so a quick head check is needed before the vehicle moves sideways.
-
17. What do the numbers on a pedestrian countdown display show?
Show answer
Answer A: The seconds remaining to finish a crossing already under way
The countdown runs during the pedestrian change interval and shows how many seconds are left before the crossing time ends.
-
18. At an intersection where every approach carries this sign, two drivers arrive at exactly the same instant. Which of them goes first?
Show answer
Answer C: The driver on the right
Order of arrival decides who goes first, and when two vehicles arrive together the driver on the right proceeds while the other gives way.
-
19. 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.
-
20. Permanent signs must be retroreflective or lighted so that
Show answer
Answer A: they show the same shape and color at night as by day
Retroreflective sheeting throws headlight light back to the driver, so a sign keeps its daytime shape and color after dark.
-
21. A Louisiana driver over 21 tests at 0.10 percent for the second time within five years. How long is the administrative suspension?
Show answer
Answer C: 365 days
A reading of 0.08 to 0.14 percent costs 180 days on a first submission but 365 days when it is a second within five years.
-
22. A broken white line separates your lane from the lane on your right. What does it permit?
Show answer
Answer C: Changing lanes when it is safe to do so
A normal broken white line marks a boundary between lanes traveling the same way that road users may cross when it is safe.
-
23. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
24. Absent a posted speed zone, what is the statutory maximum speed on an ordinary Louisiana highway?
Show answer
Answer D: 55 miles per hour
Louisiana's default statutory ceiling on a highway is 55 miles per hour; higher figures apply only to interstates, controlled access highways and multi-lane divided highways, or where a speed zone has been established.
-
25. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
-
26. What is the correct relationship between air bags and seat belts?
Show answer
Answer B: Air bags are designed to work together with seat belts, not instead of them
An air bag is a supplemental restraint that cushions one impact, while the belt keeps you in position so the bag can work and protects you in rollovers and secondary impacts.
-
27. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
-
28. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
29. What does a yield sign require of a driver?
Show answer
Answer A: Slow down, and stop when necessary, so conflicting traffic can go first
A yield sign obliges the driver to reduce to a speed suited to conditions and to stop when needed so that conflicting traffic or pedestrians are not interfered with.
-
30. Why does the situation ahead of this sign deserve extra care from a motorcyclist?
Show answer
Answer C: Because a narrow machine is easy to overlook in a mirror or a blind spot
A motorcycle fills very little of a mirror and disappears easily into a blind spot, so the rider should adjust speed and lane position to stay visible where the streams come together.
-
31. In a work zone one lane sits an inch or two lower than the lane beside it. How should you change lanes?
Show answer
Answer C: Slow down and cross the edge at a shallow angle, holding the wheel firmly
A vertical edge between lanes can catch a tire and jerk the steering. Crossing slowly at a shallow angle lets the wheel climb without grabbing.
-
32. You have begun to move into the next lane when the gap you were aiming for closes. What is the safest action?
Show answer
Answer C: Return to your own lane, cancel the signal and wait for a better gap
An unfinished lane change leaves you in a space that no longer exists, and the lane you came from is still yours.
-
33. Where is a three-point turn most clearly a bad idea?
Show answer
Answer A: On a busy street near a curve, where approaching drivers cannot see you
The maneuver leaves you blocking the road for several seconds, so it needs light traffic and a long clear view; a blind curve gives neither.
-
34. The lights at a highway-rail grade crossing begin to flash red as you approach. What must you do?
Show answer
Answer B: Stop short of the tracks and wait until the lights stop and no train is near
Flashing red lights at a crossing require a stop clear of the tracks, and you may proceed only once the lights have stopped, any gates are fully raised and no train is approaching.
-
35. Where does the restriction that starts at this sign come to an end?
Show answer
Answer D: Where the centerline markings show that overtaking is allowed again
The sign marks the start of the restricted section, and the centerline markings along the road show how far it runs and where overtaking becomes lawful again.
-
36. You are on a one-way street with two marked lanes. May you pass a slower vehicle on the right?
Show answer
Answer A: Yes, using the right lane, provided that the move is safe and signaled
On a roadway with two or more marked lanes in your direction, moving into the free lane and going by is a normal lane change rather than an unlawful pass.
-
37. Which ability does alcohol usually affect first?
Show answer
Answer A: Judgment and self control
Alcohol reduces judgment and inhibition before a drinker notices any clumsiness, which is why an impaired driver often feels perfectly capable while already driving worse.
-
38. A Louisiana driver over 21 submits to a test and registers 0.15 percent. What administrative suspension follows?
Show answer
Answer C: Two years, or 730 days
Results of 0.08 to 0.149 percent bring a 180 day suspension, while a result of 0.15 percent or higher brings a two year suspension.
-
39. The rear of your vehicle begins to slide sideways on a slippery surface. What is the correct correction?
Show answer
Answer C: Ease off the accelerator and steer in the direction you want the front of the vehicle to go
Looking and steering toward your intended path lines the front wheels up with the direction of travel, while sudden braking or a sharp opposite input usually makes the slide worse.
-
40. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?
Show answer
Answer B: Obstruction of the normal flow of traffic, which is prohibited in itself
Driving so slowly that other traffic is impeded is an offense in its own right when nothing about safety, weather or the road calls for it.
