  1. 1. Why is an underinflated tire especially risky on a long drive in hot weather?

    Show answer

    Answer C: It flexes more, builds up heat and can fail at speed

    A soft tire flexes on every rotation, and that flexing makes heat that the hot road and high speed add to until the tire can come apart.

  2. 2. You are driving at night on an unlit road using low beams. How should you choose your speed?

    Show answer

    Answer C: So you could stop within the distance your headlights light up

    Driving faster than you can stop within the lit area is called overdriving your headlights. Anything beyond the beam is invisible until it is too late to react.

  3. 3. What are front fog lights for?

    Show answer

    Answer D: Adding a low, wide beam close to the car when visibility is poor

    Fog lights throw a low, wide beam under the fog, which is why they are mounted low and are used only in poor visibility.

  4. 4. A sign at the curb reads Tow-Away Zone. What does it mean for you?

    Show answer

    Answer C: That a vehicle left there can be removed at the owner's expense

    In a tow-away zone the vehicle can be removed immediately and the owner pays the towing and storage charges to get it back.

  5. 5. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?

    A white vertical rectangle with a black border and black legend
    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.

  6. 6. The gates at a railroad crossing begin to come down as you approach. What must you do?

    Show answer

    Answer A: Stop and wait until the gates are fully raised and the lights stop flashing

    Once the gates start down you must stop clear of the tracks and wait until they are fully raised and the warning lights have stopped.

  7. 7. A bicyclist ahead of you puts the left arm straight out to the side. What is being signaled?

    Show answer

    Answer B: A left turn or a move to the left

    The left arm held straight out is the bicycle signal for a left turn, so hold back and give the rider room to cross toward the center.

  8. 8. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?

    Show answer

    Answer C: At the opening before the solid line begins

    The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.

  9. 9. Where is the best place in the car for a child safety seat?

    Show answer

    Answer A: In the rear seat, secured either with the belt or with the lower anchors

    The rear seat is furthest from most impacts and from the front airbags, and the seat must be locked in with the belt or the anchors.

  10. 10. You are waiting to turn left across two oncoming lanes when a driver in the near lane stops and waves you through. What should you do?

    Show answer

    Answer D: Turn only after checking the far lane yourself

    The waving driver cannot give away the right of way of the traffic in the second lane, which may not be stopping at all.

  11. 11. A Mississippi resident studying at an out-of-state college renews by mail. Which document must be enclosed?

    Show answer

    Answer D: A notarized letter on college letterhead confirming full-time study

    Mississippi requires a notarized letter from the college, on its letterhead, stating that the applicant is a full-time student.

  12. 12. What is the rule about leaving a child or a pet in a parked vehicle?

    Show answer

    Answer A: Never do it; the inside can turn deadly hot very quickly

    The inside of a parked vehicle heats far faster than the air outside, and cracking a window does not prevent it, so a child or animal must never be left there.

  13. 13. Four vehicles reach a four-way stop from all four directions at the same instant. How is the deadlock resolved?

    Show answer

    Answer C: Each driver yields to the vehicle on the right and they go one by one

    Yielding to the right applies to every driver, so the group untangles itself as drivers take turns rather than moving together.

  14. 14. You brake hard on a wet road and need to steer around a stalled car. How do antilock brakes help you do that?

    Show answer

    Answer B: They stop the wheels locking, so the tires can still turn the vehicle

    Locked wheels slide and cannot change direction. By preventing lockup the system lets you brake at full force and steer at the same time.

  15. 15. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?

    Show answer

    Answer C: At the southern or western edge of the state

    Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.

  16. 16. This sign leads to a crossing that has no gates and no flashing lights. What does that mean for the driver?

    A yellow circle showing a black cross and the letters R R in the side quarters
    Show answer

    Answer D: Nothing will warn of an approaching train, so the driver must check the tracks personally

    At a passive crossing there is no active device to announce a train, so the whole judgment rests on the driver, who must approach slowly enough to stop after looking along the track.

  17. 17. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?

    Show answer

    Answer B: Follow the signs and what you can see

    A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.

  18. 18. Why can a motorcycle ahead of you slow down without any warning light showing?

    Show answer

    Answer B: The rider may slow by downshifting or rolling off

    Riders often lose speed by closing the throttle or changing down, which does not switch on the brake light, so watch the machine itself and keep back.

  19. 19. You are stopped at the yield line of a roundabout when an emergency vehicle comes up behind you with lights and siren. What should you do?

    Show answer

    Answer A: Stay out of the roundabout and pull over to the right of your lane if there is room

    Never enter a roundabout ahead of an emergency vehicle and never stop inside one; wait clear of the entry so the crew can get through.

  20. 20. You are turning right onto a one-way street. Which lane of that street should you enter?

    Show answer

    Answer C: The lane closest to the right curb

    Even though every lane on a one-way street runs your way, a right turn must end in the lane nearest the right curb; you may change lanes afterwards when it is safe.

  21. 21. You are approaching a traffic light that has been green for a long time. How should you treat it?

    Show answer

    Answer C: Expect it to change and be ready to stop

    A light that has been green for a while is called a stale green light. Cover the brake and decide in advance where you could still stop safely.

  22. 22. Besides an authorized emergency vehicle, which stationary vehicle displaying authorized flashing lights triggers Mississippi's move over duty?

    Show answer

    Answer B: A utility service vehicle working on electricity, gas or water lines

    Section 63-3-809 extends the move over duty to stationary recovery vehicles, utility service vehicles, sanitation vehicles and highway maintenance vehicles.

  23. 23. The signal ahead turns yellow while you are approaching it. What does the yellow light mean?

    Show answer

    Answer C: The red is coming; stop if you can do so safely

    A steady yellow warns that the red is next. Stop if you can do so safely; enter the intersection only when stopping would be dangerous.

  24. 24. An orange sign showing the symbol of a person holding a flag or a sign paddle means that

    Show answer

    Answer D: a person is controlling traffic ahead and the driver must obey that person

    The flagger sign warns that a trained flagger is directing traffic further on, and the flagger's instructions govern movement through the work zone.

  25. 25. Some drivers believe they can multitask while driving. What does research show?

    Show answer

    Answer C: The brain switches rapidly between tasks and driving performance suffers

    The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.

  26. 26. An upward-pointing pentagon with a yellow legend and border on a blue background is used as

    Show answer

    Answer D: a county route marker

    The pentagon serves both the school warning series and county route markers, and the blue background with yellow legend identifies the county route version.

  27. 27. The circular sign shape is reserved for which warning?

    Show answer

    Answer C: Advance warning of a highway-rail grade crossing

    A round yellow sign with a black X and the letters RR is the grade crossing advance warning sign, and the circular outline is used for no other message.

  28. 28. The overhead signal above your lane changes to a steady yellow X. What should you do?

    Show answer

    Answer B: Prepare to move out of that lane

    A steady yellow X warns that the lane is about to close, so drivers should get ready to vacate it in favor of an open lane.

  29. 29. A tractor-trailer is backing slowly across the roadway to enter a loading dock. What should you do?

    Show answer

    Answer C: Stop and wait until the truck has finished the maneuver

    A backing truck driver has a very limited view and the trailer can swing unexpectedly. Trying to squeeze past in either direction risks being crushed.

  30. 30. Your vehicle is burning at the roadside. How far away should everyone keep?

    Show answer

    Answer D: At least a hundred feet away from the vehicle and upwind, out of the drifting smoke

    Burning vehicles give off toxic smoke and parts such as tires and struts can burst, so keep a long distance and stay upwind.
