Question 1 of 30
1. A signal shows a flashing yellow arrow for a left turn. What does that allow?
Show answer & explanation
Correct answer: A. A flashing yellow arrow is a yield-and-turn: you may go left after judging gaps, because oncoming traffic still has a green. It is not a protected arrow. Flash yellow means you choose the gap; solid green arrow means the gap is held for you.
2. What would a NHTSA brake-throttle override require when a pedal is stuck?
Show answer & explanation
Correct answer: A. Official NHTSA FMVSS 124 NPRM text says a brake-throttle override (BTO) system would require that input to the brake pedal in a vehicle must have the capability of overriding input to the accelerator pedal. The leftover shift-to-neutral mnemonic is not on that page; this nearby official stuck-accelerator rulemaking sentence is.
3. Does the posted speed limit stay safe in bad weather, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA speeding guidance says Speed also affects your safety even when you are driving at the speed limit but too fast for road conditions, such as during bad weather, when a road is under repair, or in an area at night that isn’t well lit. The leftover hydroplane-film sentence is not on that page; this nearby official weather-speed rule is.
4. A truck ahead signals a right turn but first swings out toward the left. What should you do?
Show answer & explanation
Correct answer: C. Long vehicles swing wide to make right turns, and the tempting gap on their right closes like a trap once the trailer comes around. Hold back and wait. Do not slide into the right side of a turning truck.
5. You must park on a hill where the road has no curb. Which way should you turn your wheels?
Show answer & explanation
Correct answer: A. With no curb to catch the car, always turn your wheels toward the road's edge, uphill or downhill. A runaway car then rolls off the travel lanes instead of into traffic. No curb: aim for the shoulder.
6. Your 20-year-old cousin is the designated driver tonight in Mississippi. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In Mississippi, drivers under 21 violate the zero-tolerance law once their BAC reaches 0.02%. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
7. On slick or snow-covered roads, what following-distance step does NHTSA list?
Show answer & explanation
Correct answer: A. Official NHTSA winter-driving guidance says On the road, increase your following distance enough so that you’ll have plenty of time to stop for vehicles ahead of you. The leftover count-the-seconds mnemonic is not on that page; this nearby official following-distance sentence is.
8. You merge onto an interstate in Mississippi posted at the state's maximum speed limit. The fastest you may legally drive there is which speed?
Show answer & explanation
Correct answer: C. Mississippi caps highway speed at 70 mph, its statewide maximum. Even on wide-open pavement, the posted number is the ceiling, and rain, fog, or traffic can make a much lower speed the only safe and legal choice.
9. A yellow diamond shows a sideways wind-sock or windswept tree. What risk is ahead?
Show answer & explanation
Correct answer: A. Crosswind warnings mark bridges, cuts, and open plains where gusts shove vans, trucks, and empty trailers. Ease off the gas and keep both hands on the wheel. If you drive something tall, treat the sign as a speed cut.
10. Headlights are required from sunset to sunrise. When else should you turn them on?
Show answer & explanation
Correct answer: B. Wipers on, lights on is the rule many states write down and testers repeat. Lights help others see you as much as they help you see. If the sky is gray or the glass is wet, flip them on.
11. Where is the official Mississippi driver handbook published?
Show answer & explanation
Correct answer: A. The DPS publishes the Mississippi handbook for free. That book is the source the knowledge test is written from. Our questions are original study items grounded in those rules, not a substitute for reading the handbook.
12. A classmate in Mississippi claims the adult DUI line is 0.10%. The official per-se BAC for drivers 21 and older is which value?
Show answer & explanation
Correct answer: C. Your classmate is using an outdated number. Mississippi treats 0.08% as the adult per-se line. Memorize the current figure from the official handbook, not a rumor from an older relative.
13. You are turning left at an intersection on a green light while an oncoming car heads straight toward the intersection. What is the rule?
Show answer & explanation
Correct answer: C. A driver turning left must yield to oncoming vehicles going straight or turning right, crossing only when there is a safe gap. Straight traffic keeps its speed and path, so the turning driver waits. Left turn equals lower priority.
14. A teen walks into a Mississippi Department of Public Safety (DPS) office in Mississippi to apply for a first learner's permit. The office can accept the application once the teen is what age?
Show answer & explanation
Correct answer: B. The DPS accepts learner's permit applications at age 15 in Mississippi. Bring proof of identity, residency, and usually a parent's signature, then pass the knowledge and vision screenings. Age is simply the first box to check.
15. How does the official NHTSA NDR code book label leaving a crash without aiding?
Show answer & explanation
Correct answer: A. Official 23 CFR 1327 Appendix A lists B01 Hit and run—failure to stop and render aid after accident. Related codes cover fatal, injury, and property-damage hit-and-run. State penalties vary; this leftover uses that official national label.
16. A classmate insists everyone must wait until 18 to start driving in Mississippi. The real minimum age for a learner's permit is which of these?
Show answer & explanation
Correct answer: D. Your classmate is wrong: Mississippi grants learner's permits at 15. Starting earlier gives you months of supervised practice while risk is lowest. When rules feel fuzzy, confirm them in the official state driver handbook.
17. A traffic officer directs you to proceed over a Mississippi railroad crossing. What should you do?
Show answer & explanation
Correct answer: A. Mississippi says if a traffic officer directs you to proceed over a railroad crossing, follow the order immediately. That is the exception to the usual “never beat a train” rule. Still look both ways as you cross.
18. You are 25 and had wine at a dinner party in Mississippi. Before driving home, you check the law. At what BAC does driving become illegal for you?
Show answer & explanation
Correct answer: D. For adult drivers in Mississippi, driving is illegal at a BAC of 0.08% or above. Because impairment starts before the limit, the safest plan after drinking is a ride share, taxi, or sober designated driver.
19. A yellow diamond sign shows a truck tilted nose-down on a black slope. You are about to descend a long, steep grade. What is the proper technique?
Show answer & explanation
Correct answer: C. On a steep downgrade, shift to a lower gear before descending so engine braking holds your speed, and use the brakes sparingly. Constant braking overheats the pads until they fade and fail. Gears save brakes; brakes alone can quit.
20. When a vehicle with flashing lights is stopped on or next to a roadway, what does official NHTSA Move Over guidance say drivers should do?
Show answer & explanation
Correct answer: A. Official NHTSA Move Over guidance says all 50 states have Move Over laws. When a vehicle with flashing lights is stopped on or next to a roadway, drivers approaching the vehicle should change into a lane not immediately adjacent to the vehicle, or slow down to a reasonable speed if you’re unable to safely make a lane change.
21. On a multilane highway, white lines separate the lanes. What does the white color tell you about the traffic around you?
Show answer & explanation
Correct answer: B. White lines divide lanes of traffic that flow the same way, while yellow divides opposing flows. Reading line color at a glance tells you instantly where oncoming cars can be. White means with you, yellow means toward you.
22. A work zone is posted 45 mph with workers on foot beside the cones. Why should you treat that number as a hard ceiling?
Show answer & explanation
Correct answer: A. Work-zone limits protect people standing inches from traffic, and many states double the fine. Slow to the posted number before the first cone. Orange zone, orange alert: the speed is real and the penalty is steeper.
23. Mississippi enforces 'zero tolerance' for underage drinking and driving. In practice, a driver under 21 violates this law at what BAC?
Show answer & explanation
Correct answer: A. Zero tolerance in Mississippi means the under-21 line sits at 0.02%, so even one drink can end in a suspended license. The memory hook is simple: under 21 means zero drinks before you drive.
24. You approach a malfunctioning Mississippi traffic light. What should you do?
Show answer & explanation
Correct answer: A. Mississippi warns that you will sometimes encounter a malfunctioning traffic light. Slow down, use caution, and yield. Do not assume a dark or stuck head is yours to take. The flashing-yellow chapter sits next to that warning for a reason.
25. If your car stalls on a railroad track, what does NHTSA say to do first?
Show answer & explanation
Correct answer: A. Official NHTSA railroad-crossing guidance says If your car stalls on a track, quickly get everyone out — even if you don’t see a train coming. Run away from the tracks and your car to avoid being hit by flying debris. Call the number on the blue emergency notification system sign.
26. Signs on Mississippi highways vary from road to road, but the law sets one absolute top limit for the fastest routes. That limit is which value?
Show answer & explanation
Correct answer: D. By statute, 70 mph is the fastest any Mississippi road can be posted. Below that ceiling, engineers set each road's limit for its design and traffic, which is why the posted sign on your road governs.
27. Can a small amount of alcohol affect driving, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA drunk-driving guidance says even a small amount of alcohol can affect driving ability. Even small amounts of alcohol affect one’s brain and the ability to drive. Testers invent leftover one-beer-is-nothing courtesy.
28. A freeway lane is marked with white diamond symbols, and a sign says the lane is for high-occupancy vehicles (HOV 2+). Who may drive in it during the posted hours?
Show answer & explanation
Correct answer: B. Diamond-marked HOV lanes are reserved for vehicles meeting the posted occupancy, like two or more people in an HOV 2+ lane. Rewarding shared rides moves more people in fewer cars. The diamond means special rules, so read the sign before entering.
29. A center lane is bordered on each side by a solid yellow line with a broken yellow line inside it, and white left-turn arrows are painted for both directions. How may you use this lane?
Show answer & explanation
Correct answer: A. A two-way left-turn lane is shared by both directions for left turns only. Enter just before your turn, watch for opposing drivers using the same lane, and never travel or pass in it. Turn, do not cruise.
30. In Mississippi, how close to a fire hydrant may you legally park?
Show answer & explanation
Correct answer: A. Mississippi bans parking within ten feet of a fire hydrant so crews can hook hoses instantly during a fire; a blocked hydrant costs precious seconds. Picture one car length of clear curb around every hydrant.
