1. 1. If another road user is not following the right-of-way rules, what should a driver do?

   1. Accelerate to establish control of the intersection
   2. Insist on proceeding because the law gives the driver priority
   3. Let that road user proceed even when the driver is legally entitled to go
   4. Stop in the travel lane and confront the other road user
   Show answer

   Let that road user proceed even when the driver is legally entitled to go. Louisiana explains that right-of-way rules identify who must yield, but they do not make a collision impossible or grant permission to force a conflict. If another driver or pedestrian fails to follow the rules, let that person have the right-of-way even when it belongs to you. Insisting, accelerating, or confronting someone increases the chance of a crash. Scan for mistakes, slow when needed, and preserve a clear escape path. Legal priority is useful for orderly traffic, but avoiding impact remains the immediate safety decision.

2. 2. What kind of information does a yellow diamond-shaped roadway sign provide?

   1. A regulatory command such as a posted speed limit
   2. A warning about an upcoming condition or hazard
   3. A guide to lodging, food, or fuel
   4. A route number for an interstate highway
   Show answer

   A warning about an upcoming condition or hazard. The yellow diamond category warns about conditions ahead, including curves, side roads, traffic flow, or another hazard. It gives the driver time to prepare, but it is not itself a speed-limit command. Service signs identify places such as fuel or lodging, and route shields identify road systems. Use the warning as a prompt to scan, reduce speed when needed, and follow any later regulatory sign or pavement marking.

3. 3. What do double solid yellow lines mark on a roadway with four or more lanes?

   1. A shared lane reserved for travel in either direction
   2. A lane where passing is required before the next intersection
   3. The edge of a one-way roadway where vehicles may park
   4. The center of the roadway, where crossing to pass is prohibited
   Show answer

   The center of the roadway, where crossing to pass is prohibited. Double solid yellow lines mark the center of a roadway with four or more lanes. A driver may cross them to make a turn, but may not cross them to pass. The choice describing a shared lane confuses these markings with the special center turn lane, which uses a different solid-and-dashed pattern. Treat the double solid lines as a barrier to overtaking, then look for a legal opening or turn location before crossing them.

4. 4. How should a driver use a roundabout after entering it?

   
   1. Do not stop inside; traffic already in the roundabout has the right-of-way
   2. Stop inside whenever another vehicle approaches from the right
   3. Drive clockwise against the circulating traffic to reach the exit
   4. Change lanes repeatedly until the desired exit appears
   Show answer

   Do not stop inside; traffic already in the roundabout has the right-of-way. Once inside a roundabout, do not stop, and remember that the vehicle circulating there has the right-of-way. Drivers yield to the left before entering, then follow signs and prepare for the chosen exit. Stopping inside disrupts the circle, and traveling against the circulation direction creates a head-on conflict. Repeated lane changes add unnecessary risk. Enter slowly, maintain a steady path, check the mirror before exiting, and use the turn signal as you leave.

5. 5. Which condition requires a Louisiana driver to stop at a railroad crossing?

   1. A lowered crossing gate
   2. A clear track with no warning device active
   3. A green traffic light on a nearby street
   4. A vehicle parked more than 100 feet away
   Show answer

   A lowered crossing gate. A lowered crossing gate is one of the conditions that requires a stop at a Louisiana railroad crossing. The guide also identifies a flashing signal with an approaching train and several train-warning conditions. A clear track does not cancel an active gate, and a nearby green light or a distant parked vehicle does not determine whether the rail crossing is safe. Stop before the gate, remain stopped until it is raised, and never drive around it. The key cue is the crossing control itself: an active gate means stop and wait.

6. 6. By how much can proper tire inflation improve gas mileage, according to the Louisiana guide?

   1. Not at all
   2. About 25 percent
   3. As much as 3.3 percent
   4. About 50 percent
   Show answer

   As much as 3.3 percent. Keeping your tires properly inflated can improve gas mileage by as much as 3.3 percent, and tires need at least 1/16 of an inch of tread depth. Underinflated tires also overheat and wear on the edges, and understeer, where the front tires lose traction before the rear in a corner, gets worse. Check pressure monthly when the tires are cold.

7. 7. An impaired Louisiana driver injures someone, but not seriously. What is the penalty for vehicle negligent injury?

   1. A fine of not more than $1,000 or not more than six months in prison, or both
   2. 5 to 30 years in prison
   3. A fine up to $2,000 or up to five years
   4. No penalty if the injury is minor
   Show answer

   A fine of not more than $1,000 or not more than six months in prison, or both. Vehicle negligent injury, under R.S. 14:39.1, is injuring someone while under the influence of alcohol or drugs or with a BAC of 0.08% or more. Penalties include a fine of not more than $1,000 or imprisonment for not more than six months, or both. Up to $2,000 or five years is not this offense's penalty, and serious bodily injury is charged as a separate, more serious crime. Five to 30 years is for vehicular homicide. A minor injury is still a crime.

8. 8. What must a driver do when an emergency vehicle sounds a siren and flashes warning lights?

   
   1. Pull to the right edge clear of intersections and stop
   2. Continue driving if the emergency vehicle is in another lane
   3. Stop in the middle of the nearest intersection
   4. Follow closely so other traffic moves aside
   Show answer

   Pull to the right edge clear of intersections and stop. The Louisiana rule requires drivers to yield to an emergency vehicle using both a siren and flashing warning lights. Pull to the right edge of the roadway, clear of intersections, and remain stopped until the vehicle passes. Stopping in an intersection can obstruct the emergency response, while following closely is unlawful and dangerous. The rule applies to traffic in both directions, so an approaching vehicle does not become someone else's problem merely because it is not directly behind you. Look for additional emergency vehicles before moving again.

9. 9. What causes hydroplaning as speed rises on a wet roadway?

   1. The brakes lock because the road is too dry
   2. The engine becomes flooded by rainwater
   3. The tires ride up on a layer of water and lose pavement contact
   4. The steering wheel automatically turns toward the shoulder
   Show answer

   The tires ride up on a layer of water and lose pavement contact. Hydroplaning begins when water cannot be removed from the roadway quickly enough by the tires. The tires then ride up on the water like skis, reducing or eliminating contact with the pavement. That loss of contact means the driver cannot rely on normal braking, acceleration, or steering. The explanation involving a flooded engine confuses a roadway traction problem with a mechanical problem. Reduce speed on wet roads, maintain recommended tire pressure, and keep usable tread so water can escape through the grooves.

10. 10. Using Louisiana's following-distance method, what gap should a driver maintain in ordinary conditions?

    1. At least ten car lengths at every speed
    2. Exactly one second behind the vehicle ahead
    3. At least three seconds behind the vehicle ahead
    4. No gap is needed when traffic is moving
    Show answer

    At least three seconds behind the vehicle ahead. The manual's ordinary benchmark is the three-second rule, which works at any speed. Pick a fixed object beyond the vehicle ahead, begin counting when that vehicle passes it, and make sure your vehicle takes at least three seconds to reach the same point. A one-second gap leaves little time for a sudden stop, while a car-length measurement changes meaning as speed changes. Ten car lengths is not the handbook's test. If you reach the checkpoint too soon, ease off and repeat the count at another object until the full time cushion is present.

11. 11. What is a two way left turn lane intended for?

    
    1. Parking while waiting for a gap
    2. Passing slower traffic in either direction
    3. Traveling straight through an intersection
    4. Left turn maneuvers only
    Show answer

    Left turn maneuvers only. The center lane marked with solid and dashed yellow lines is shared by traffic from both directions, but its use is limited to left turns. It is not a travel lane, passing lane, or parking area. Enter it only when preparing for a left turn, check for opposing users, and leave it promptly. Using the lane to continue straight can place two vehicles on a collision path because both directions may enter it. Read the marking as a narrow turning space, not an extra lane for through movement.

12. 12. During what hours is an intermediate licensee generally prohibited from driving in Louisiana?

    1. 11:00 p.m. to 5:00 a.m.
    2. 9:00 p.m. to 6:00 a.m.
    3. 10:00 p.m. to 4:00 a.m.
    4. Midnight to 7:00 a.m.
    Show answer

    11:00 p.m. to 5:00 a.m.. An intermediate licensee generally may not drive from 11:00 p.m. through 5:00 a.m. The manual allows an exception when the driver is accompanied by a licensed adult at least 21 or a sibling at least 18. The separate passenger restriction begins at 6:00 p.m., which can make that time appear in another rule, but it does not change the driving curfew. Before a late trip, identify whether the issue is the curfew or passenger limit and confirm that the listed adult or sibling exception applies.

13. 13. What action is prohibited by a red slash over a U-shaped arrow?

    
    1. Turning right at the next intersection
    2. Making a U-turn
    3. Passing a slower vehicle on a straight road
    4. Entering a one-way street in the arrow's direction
    Show answer

    Making a U-turn. A red circle with a red slash identifies a regulatory sign that prohibits the action represented by the symbol. On the pictured sign, the symbol shows a U turn, so the barred maneuver is turning around. The slash does not automatically prohibit a right turn, ordinary passing, or travel in the permitted direction on a one way street. Read the symbol first, then obey any other signs or markings governing the lane. The visual cue is the red slash crossing the maneuver that drivers must not make.

14. 14. What BAC is the Louisiana legal limit for a driver age 21 or older?

    1. 0.15%
    2. 0.02%
    3. 0.04%
    4. 0.08%
    Show answer

    0.08%. For a driver who is 21 or older, Louisiana lists 0.08% as the legal BAC limit. The 0.02% figure applies to drivers 20 and younger, while 0.04% applies when operating a commercial motor vehicle. The 0.15% choice is not the ordinary adult threshold; it is a higher BAC level tied to a more severe administrative suspension after testing. The practical cue is to identify the driver's age and vehicle category before choosing a number. Alcohol can impair driving before the listed limit, so the safest plan is not to drive after drinking.

15. 15. How fast should a driver generally travel inside a Louisiana roundabout?

    1. The posted highway speed
    2. 35 mph or less
    3. 15 mph or less
    4. At least 25 mph
    Show answer

    15 mph or less. The guide says speeds of 15 mph or less are adequate inside a roundabout. The 35 mph option is associated with a different speed rule in the manual, not the circular intersection. Using the ordinary highway limit would ignore the tight geometry and conflict points of the roundabout, while a minimum speed is not required. The cue is the word inside: reduce speed before entering and maintain a slow pace through the circle.

16. 16. What is a driver required to do when a high-speed road has a posted minimum speed?

    1. Ignore the minimum when traffic is light
    2. Stay below the minimum to conserve fuel
    3. Use the shoulder whenever traveling at the minimum
    4. Travel at least the posted minimum unless conditions require otherwise
    Show answer

    Travel at least the posted minimum unless conditions require otherwise. Some high-speed roads post a minimum speed, and drivers are legally required to travel at least that fast so they do not become a hazard to other drivers. Light traffic does not erase the sign, and using the shoulder is not the stated solution. Conservation of fuel is not a reason to obstruct normal traffic. The cue is the word minimum: it marks the slowest lawful pace for ordinary conditions, subject to any need to slow for safety.

17. 17. What information is commonly provided by a blue service sign?

    1. A prohibition against passing
    2. The location of services such as gas stations or hospitals
    3. A warning about a curve or slippery pavement
    4. The maximum speed allowed on the road
    Show answer

    The location of services such as gas stations or hospitals. Blue service signs direct travelers to useful facilities, including rest areas, gas stations, hotels, and hospitals. They are informational rather than warnings, prohibitions, or speed commands. No-passing rules belong to regulatory or warning signs, curves and slippery pavement are hazard messages, and maximum speed is posted on a regulatory sign. A simple roadside cue is color plus purpose: blue helps locate a service. Follow the symbol or wording and make any exit or turn safely.

18. 18. What must other drivers do when encountering a funeral procession?

    1. Pass the procession on the shoulder
    2. Enter the line whenever a gap appears
    3. Use the horn to make the procession stop
    4. Yield the right-of-way to the vehicles in the procession
    Show answer

    Yield the right-of-way to the vehicles in the procession. Louisiana requires all motor-vehicle operators to yield the right-of-way to vehicles participating in a funeral procession. Entering a gap, forcing the line to stop, or passing on the shoulder disrupts the procession and creates unpredictable movements. Slow down, remain patient, and wait until the procession has passed before proceeding. The guide also notes that procession vehicles use headlights and emergency lights, which can help identify the group. Treat the line as a continuous movement rather than as separate vehicles that can be cut between.

19. 19. A Louisiana student who is 16 withdraws from school before graduating. What can happen?

    1. Nothing, because school is unrelated to driving
    2. The driving privilege can be lost
    3. Only a fine is charged
    4. The license is upgraded
    Show answer

    The driving privilege can be lost. The guide lists withdrawing from school before graduation, if you are 15 but less than 18, or being found habitually absent or tardy, as a way to lose the driving privilege. So school status does matter for young drivers. A fine alone is not the listed outcome, and nothing about leaving school upgrades a license. Staying enrolled and attending regularly is part of keeping the privilege for drivers in this age range, alongside safe driving.

20. 20. A Louisiana driver has a BAC of 0.20% at 2:00 a.m. About what will it still be at noon?

    1. 0.00%
    2. About 0.05%
    3. 0.15%
    4. About 0.10%
    Show answer

    About 0.05%. The guide says the body processes about 0.015% of alcohol per hour. Its own example: a BAC of 0.20% at 2:00 a.m. will be more than 0.10% at 8:00 a.m. and still 0.05% at noon the next day. So the driver is not sober by noon, and 0.00% is wrong. About 0.10% is the 8:00 a.m. figure, and 0.15% would mean almost no alcohol was processed. Only time lowers BAC.
