1. 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.
-
2. Traffic is entering the freeway from a ramp ahead of you and you are in the right lane. What should you do?
Show answer
Answer C: Move to another lane if it is safe, or adjust your speed to make room
Merging drivers may have little room to adjust. Helping them in by changing lanes or easing your speed prevents conflicts even though they must legally yield to you.
-
3. What driver education must a Louisiana applicant under 18 complete before a first license?
Show answer
Answer B: Thirty hours of classroom instruction and eight hours of actual driving instruction
An applicant under 18 must complete a driver education course of 30 classroom hours and 8 hours of actual driving instruction, with no more than four driving hours taken in one day.
-
4. The tire pressure monitoring symbol lights up on your dashboard. What is the system telling you?
Show answer
Answer A: At least one tire is significantly underinflated
The system warns when a tire falls well below the recommended pressure. Check all four with a gauge and inflate to the placard figure while they are cold.
-
5. Your wiper blades smear the windshield instead of clearing it. What should you do?
Show answer
Answer C: Replace the blades, because smearing means that the rubber is worn
Worn or hardened rubber cannot wipe cleanly, and blades are cheap compared with driving without a clear view.
-
6. A freeway sign reads BUSES ONLY ON SHOULDER 6 AM TO 9 AM. Who may drive on the shoulder then?
Show answer
Answer A: Only the vehicles named on the sign, during the hours shown
Shoulder running is granted by the sign to the class of vehicle and the hours the sign names, and it does not turn the shoulder into a general travel lane.
-
7. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
-
8. 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.
-
9. What belongs in a basic emergency kit carried in a car?
Show answer
Answer D: A flashlight, a first aid kit, jumper cables and some warning devices
A useful kit lets you see, be seen, treat an injury and restart the vehicle; carrying loose gasoline is a fire risk.
-
10. You are driving through a residential area where parked cars hide the side streets. What is the safest approach?
Show answer
Answer C: Slow down and cover the brake as you pass each opening
Where parked vehicles hide side streets and driveways, lower speed and a covered brake buy the time you lose in sight distance.
-
11. Where may an automated speed enforcement device lawfully operate under Louisiana's school zone rule?
Show answer
Answer B: Only inside a lawfully posted school zone
Louisiana confines automated speed enforcement and mobile speed cameras to school zones that are lawfully posted, and bars citations where the required entrance and exit signage is missing.
-
12. You are approaching the entry of a roundabout and a pedestrian is crossing the marked crosswalk on your approach lane. What must you do?
Show answer
Answer D: Stop before the crosswalk and let the pedestrian cross
Roundabout crosswalks sit a short distance back from the yield line, and drivers must yield there before they ever reach the circulating lanes.
-
13. You are in a marked passing zone but a steady stream of oncoming traffic is coming toward you. What does the broken center line allow?
Show answer
Answer C: A pass only when the road is clear, so you have to stay behind
A passing zone marks where the sight distance is adequate, but it never gives permission to enter a lane that another vehicle is occupying.
-
14. The passenger-side mirror on most vehicles is convex. What does this mean for the driver?
Show answer
Answer D: Vehicles in that mirror are closer than they appear
A convex mirror gives a wider view but shrinks what it shows, so a vehicle looks smaller and therefore farther away than it really is. Allow for this before changing lanes.
-
15. You are driving through a long curve on a road with two lanes in your direction. What is correct?
Show answer
Answer A: Stay within your own lane all the way through, adjusting speed before you enter
Wandering out of your lane in a curve puts you into the path of a vehicle you cannot see, and the slowing belongs before the curve rather than in it.
-
16. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
17. The motorcyclist ahead of you keeps moving from one side of the lane to the other. What should you understand?
Show answer
Answer B: The rider is avoiding surface hazards and staying where drivers can see the bike
Riders shift their lane position to avoid debris, grease strips and potholes and to be seen. That movement is normal and never an invitation to share the lane.
-
18. 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.
-
19. A Louisiana owner's compulsory insurance has been lapsed for 45 days. What reinstatement fee applies?
Show answer
Answer C: 250 dollars
Louisiana charges 100 dollars for a lapse of 1 to 30 days, 250 dollars for a lapse of 31 to 90 days, and 500 dollars once the lapse exceeds 90 days.
-
20. A wheel comes off your car while you are driving. What should you do?
Show answer
Answer A: Hold the wheel firmly, ease off the gas and steer gently to the shoulder
A firm grip and a gradual slowing keep the vehicle straight, while hard or sudden braking makes a damaged corner pull the car out of line.
-
21. Why is it often safer to back into a parking space than to back out of one?
Show answer
Answer D: Because you leave the space going forward, with a clear view
Backing into the space puts the difficult maneuver where you are stopped and looking around, and lets you drive out facing the traffic and pedestrians.
-
22. What does a flashing yellow traffic light mean?
Show answer
Answer B: Slow down and proceed with caution
A flashing yellow lets you enter the intersection cautiously after yielding to pedestrians and to conflicting traffic that is already there.
-
23. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
24. You are making a U-turn at a signal on a green left arrow. Who must you still watch for?
Show answer
Answer D: People in the crosswalk you will cross as you come around
Even a protected arrow does not clear the crosswalk, and a U-turn sweeps across a crosswalk that pedestrians may already be using.
-
25. A reduced speed limit posted with this sign and a plaque giving hours is in force
Show answer
Answer C: during the hours shown on the plaque, or while the beacon is flashing
A school speed limit applies during the periods stated on the plaque or while the attached beacon flashes, and the regular limit governs outside those periods.
-
26. Your car begins to lose power on a freeway and you must stop. Where should you try to bring it to a halt?
Show answer
Answer A: As far off the right side of the road as you can get, beyond the edge line
A disabled vehicle should be moved completely clear of the travel lanes, on the right, so that traffic can pass without changing course.
-
27. An orange background with a black legend on a sign indicates
Show answer
Answer B: a temporary traffic control or work zone situation
Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.
-
28. On what basis may the Louisiana Department of Transportation and Development set a speed limit different from the statutory one?
Show answer
Answer A: An engineering and traffic investigation of the road in question
Louisiana lets the department declare a different reasonable and safe maximum where an engineering and traffic investigation shows the statutory figure is greater or less than is safe.
-
29. 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.
-
30. Why are sign shapes and colors standardized across the whole country?
Show answer
Answer D: So a driver knows the kind of message before reading it
Uniform shapes and colors let a driver classify a sign as regulatory, warning or guide from a distance, before the legend can be read.
-
31. What is the right speed for a normal right turn at a city corner?
Show answer
Answer C: Slow enough to hold your lane and stop for a pedestrian
A city right turn is tight and crosses a crosswalk, so the correct speed is one that keeps you inside your lane and still allows a stop.
-
32. You are approaching a yield sign on a ramp that joins a busy street. What does the sign require?
Show answer
Answer A: Slow down, be ready to stop, and let the other traffic go first
A yield sign means you must slow, be prepared to stop and give way to traffic on the road you are entering; a full stop is required only when traffic makes it necessary.
-
33. Some crosswalks are marked with two transverse lines and others with a row of wide bars laid along the direction of travel. Why is the second pattern used?
Show answer
Answer B: It is far easier for an approaching driver to see
Longitudinal bar patterns are used where extra visibility is wanted, such as an uncontrolled crossing or one near a school, because they show up much better from a car.
-
34. The left-turn signal facing you shows a flashing yellow arrow. What does it mean?
Show answer
Answer C: You may turn left after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow permits a left turn but gives no protection, so you must yield to oncoming vehicles and to people in the crosswalk.
-
35. A farm implement ahead of you on a two-lane road is wider than its own lane. What should you do?
Show answer
Answer D: Hang back until you can see past it and pass only with a clear road
Wide equipment hides the road ahead and may extend farther across the center line than it appears, so the pass needs more room and a much better view.
-
36. A pedestrian using a white cane or walking with a guide dog starts to cross the street ahead of you. What must you do?
Show answer
Answer A: Yield and stay stopped until the person has finished crossing
A white cane or guide dog identifies a pedestrian who may not be able to see your vehicle, so you must yield and wait rather than maneuver around the person. The horn can confuse the pedestrian or the dog.
-
37. A pedestrian signal displays a steady walking person symbol. What does it mean for a pedestrian at that corner?
Show answer
Answer B: The pedestrian may start crossing in the direction of the signal
The steady walking person permits a pedestrian to begin the crossing, while still yielding to vehicles already lawfully in the intersection.
-
38. Why should you make sure your turn signal has stopped flashing after a lane change?
Show answer
Answer A: A signal left flashing tells other drivers that you intend to move again
Other drivers act on your signals, so one that is left on gives them false information about what you are about to do.
-
39. A SHOULDER DROP OFF sign warns that
Show answer
Answer B: there is a step down from the pavement to the shoulder
The sign is used where the edge of the pavement stands several inches above the shoulder, which can grab a wheel and pull the vehicle sideways.
-
40. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
