1. What is the maximum speed limit for passenger vehicles on Mississippi interstate highways?
Show answer
Answer C: 70 mph
Mississippi sets the interstate maximum for passenger automobiles at 70 mph, and the manual states it applies both day and night.
-
2. You are towing a loaded trailer for the first time. How should you drive?
Show answer
Answer A: Slow earlier and keep a longer following gap
A trailer adds weight and length, so stopping takes longer and every maneuver needs more room and more warning.
-
3. In a work zone a flagger is directing traffic in a way that conflicts with the posted signs. Whom do you follow?
Show answer
Answer B: The flagger's directions
A flagger controls traffic through a work area that changes from day to day, and those instructions take precedence over the fixed signs and markings in that zone.
-
4. What is the first thing to do once your disabled vehicle is stopped on the shoulder?
Show answer
Answer A: Switch on the hazard warning lights so other drivers can see the vehicle
Hazard lights are the fastest way to make a stopped vehicle visible, and everything else can follow once traffic has been warned.
-
5. The only person offering you a ride home has been drinking. What should you do?
Show answer
Answer B: Do not get in; find another way home
A passenger in an impaired driver's vehicle shares all of the risk and can do nothing about it from the seat, so the only safe answer is another ride.
-
6. 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.
-
7. About how far ahead do low beam headlights let you see on a dark road?
Show answer
Answer B: About 250 feet
Low beams light roughly 250 feet of road, and high beams roughly 350 to 500 feet, which sets the limit on a safe night speed.
-
8. 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.
-
9. Your vehicle stalls on railroad tracks and you see a train approaching. What should you do?
Show answer
Answer D: Get everyone out and run toward the train at an angle away from the tracks
Leave the vehicle at once. Running toward the oncoming train and away from the tracks keeps you clear of the wreckage, which is thrown forward in the direction the train is moving.
-
10. On an overhead guide sign, the small exit number panel sits above the left-hand end rather than the right. What does that placement tell you?
Show answer
Answer A: The exit leaves from the left side of the roadway
The exit number plaque is placed on the side from which the ramp leaves, which gives advance notice of the unusual left-hand exit.
-
11. 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.
-
12. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
13. 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.
-
14. What do zero tolerance laws mean for a driver who is under 21?
Show answer
Answer B: They commit a violation at an alcohol level far below the adult limit
Drivers under 21 may not legally drink, so every state sets a limit far below the adult one and treats even a trace reading as a violation. The exact figure is set by each state, and the penalty usually includes losing the license.
-
15. Three Mississippi children who need booster seats ride in a car whose rear seat has only two lap and shoulder belts. What does the law require?
Show answer
Answer A: Only the two children in the lap and shoulder belt seats need boosters
Where more than two children who need boosters travel and the rear seat has only two lap and shoulder belts, only the children in those seats need a booster; the others may use a lap belt.
-
16. Your vehicle has broken down at night on a rural road and your phone has no signal. What is the safest thing to do?
Show answer
Answer C: Stay with the vehicle, keep the hazard lights on and wait for help
A lit vehicle is far easier to find than a person walking in the dark, and running the engine while you sleep risks carbon monoxide.
-
17. You are stopped at a stop sign where your road ends at a two-way through street and you plan to turn left. What must you yield to?
Show answer
Answer B: Traffic from both directions and any pedestrians crossing
A left turn from the stem of a T crosses the near lane and joins the far one, so you give way to traffic in both directions and to pedestrians.
-
18. 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.
-
19. How does braking distance change if you double your speed?
Show answer
Answer D: It grows much more than twice as long
Braking distance increases with the square of speed, so doubling speed roughly quadruples the distance needed to stop.
-
20. You are parked legally, but a police officer tells you to move the vehicle. What should you do?
Show answer
Answer B: Move it as directed, because an officer overrides the signs
Directions from a police officer or a firefighter take precedence over signs and markings, whether they are directing traffic or clearing a street.
-
21. Someone has stepped into a marked crosswalk in the middle of a block ahead of you. What should you do?
Show answer
Answer A: Slow down, stop before the markings and let the person cross the street
A marked mid-block crosswalk carries the same duty as one at a corner: give way to the person crossing, stopping if that is what letting them cross safely takes.
-
22. 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.
-
23. You are stopped in traffic at a red light when an ambulance comes up behind you with its siren on. What is the correct action?
Show answer
Answer D: Stay put until you can move aside legally and safely
You must not run a red light or make an unsafe move to yield; wait, then pull to the side once the way ahead lets you do it safely.
-
24. You have started to pass and you see the no-passing zone beginning ahead. What should you do?
Show answer
Answer D: Ease off, drop back and return to your own lane
A pass must be completed before the no-passing zone starts. If it will not fit, abandon it and slot back in behind.
-
25. A driver holds a steady highway speed into the section this sign warns about. What is the most likely result?
Show answer
Answer B: The vehicle runs wide toward the outside and can cross into another lane or leave the pavement
Holding speed into a change of alignment asks the tires for more side grip than they can supply, so the vehicle runs wide and the driver is left with less room to correct.
-
26. A regulatory sign posted at the start of a road reads LENGTH LIMIT 30 FEET. What does it control?
Show answer
Answer B: The overall length of vehicle allowed on that road
Some states post a length limit where tight curves or narrow structures lie ahead; it bars vehicles or combinations longer than the figure shown from using that road.
-
27. A truck passes you in heavy rain and its spray blanks out your windshield. What should you do?
Show answer
Answer B: Hold the wheel steady, ease off slightly and let the wipers clear it
The blackout lasts a second or two. Keeping your line and easing off is far safer than braking hard or steering blind toward the shoulder.
-
28. In Mississippi, a child under what age must be secured in a child passenger restraint device?
Show answer
Answer B: Under 4 years old
Mississippi requires children under four years old to ride in a child passenger restraint device meeting applicable safety standards.
-
29. What is the safe way to carry a dog in a car?
Show answer
Answer C: In a secured crate, or in a harness attached to a seat belt anchor
An unrestrained animal distracts the driver and becomes a heavy projectile in a crash, so it should be crated or harnessed.
-
30. Visibility drops suddenly and you decide to leave the highway. What is the safest way to do it?
Show answer
Answer A: Take the next exit or a wide pull off, well clear of the traffic lanes
Get right off the traveled way, and off the shoulder too if you can, because vehicles in poor visibility often drift onto the shoulder.
