1. A driver has to stop for a train at this sign. How far back from the nearest rail should the vehicle be held?
Show answer
Answer C: No closer than roughly fifteen feet
A train and its load overhang the rails, so stopping no closer than about fifteen feet keeps the vehicle outside the space the train actually sweeps.
-
2. When is a driver or rider most likely to need hand and arm signals instead of the vehicle turn signal lamps?
Show answer
Answer D: When the lamps have failed or cannot be seen because of glare or a load
Hand and arm signals replace or reinforce the lamps whenever the lamps do not work or cannot be seen clearly by other road users.
-
3. You are stopped at a stop sign waiting to turn onto a highway where traffic moves at 55 mph. How should you choose your gap?
Show answer
Answer A: Wait for a much larger gap than the one you would accept on a city street
Fast traffic covers ground while you are still accelerating, so the gap that feels adequate at 25 mph is dangerously short at highway speed.
-
4. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
5. A sign on a long downgrade points to a runaway vehicle ramp. What is that ramp for?
Show answer
Answer C: Trucks that have lost braking ability on the grade
A runaway ramp is an escape lane of loose material that stops a heavy vehicle whose brakes have overheated or failed, so it must always be left clear.
-
6. Which headlight setting should you use in dense fog?
Show answer
Answer B: Low beams
High beams reflect off the water droplets in fog and bounce glare back at you, while low beams aim downward and light the road without that mirror effect.
-
7. You have just passed a large truck on the freeway. Why is it dangerous to pull back in front of it and then brake for your exit?
Show answer
Answer B: A loaded truck needs much more distance to stop than a car
A fully loaded tractor-trailer can need the length of a football field or more to stop from highway speed. Cutting in and braking leaves the driver no room to avoid hitting you.
-
8. Mississippi's speed table lists a minimum as well as a maximum for interstates and four-lane state and US highways. What is that minimum?
Show answer
Answer A: 40 mph
Mississippi sets a minimum speed of 40 mph for interstates and four-lane state and US highways so that slow vehicles do not obstruct the flow.
-
9. While you wait for the ambulance at a crash, what is the most useful help you can give?
Show answer
Answer C: Keep the person still and warm, and press down firmly on any heavy bleeding
Keeping an injured person still and warm and controlling bleeding are among the few things a bystander can safely do.
-
10. What do yellow lines painted on a roadway separate?
Show answer
Answer D: Traffic moving in opposite directions
Yellow markings separate opposing streams of traffic, and they also mark the left edge of a divided highway or a one-way roadway.
-
11. Why is parking next to a fire hydrant or in a marked fire lane prohibited?
Show answer
Answer D: It would delay firefighters who need immediate access to the hydrant or the building
Fire hydrants and fire lanes must remain clear at all times so emergency crews can connect hoses and reach a building without delay.
-
12. A fire truck with lights and siren has just passed you and is heading down the same road. How closely may you follow it?
Show answer
Answer B: Well back, because following a responding emergency vehicle closely is illegal
Following a responding emergency vehicle closely is prohibited; the exact minimum distance is set by each state, so stay far enough back to keep the scene and other responders clear.
-
13. The green left-turn arrow ends and a steady red ball comes on for your lane, at an intersection where no turn on red is allowed. What must you do?
Show answer
Answer D: Stop and wait, because no turn is allowed while the red ball is lit
Once a red indication faces your lane and no turn on red is permitted there, the turn is over; only a vehicle already inside the intersection completes its movement.
-
14. A child seat was in the car during a moderate crash. What should be done with it?
Show answer
Answer A: Replace it, because a seat that has been through a crash may be weakened
Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.
-
15. What is worth carrying in the vehicle during a winter trip?
Show answer
Answer A: A blanket, a flashlight, a scraper and a small shovel
A winter kit keeps you warm and visible if you are stopped for hours, and lets you clear glass and dig the wheels out. Hot water can crack cold glass.
-
16. You are stopped at a steady red arrow pointing right, and no sign or state rule permits turning on a red arrow. May you turn right?
Show answer
Answer A: No, you must wait until the red arrow goes out and a green signal appears
A steady red arrow prohibits the movement it points to until a signal permitting it appears. Only a posted sign or a specific state rule allows a turn on a red arrow after a complete stop, so without one you must wait.
-
17. A row of solid white triangles points toward you across your lane. What does it mark?
Show answer
Answer A: The place to yield to traffic or people ahead
A yield line of triangles shows drivers exactly where to give way, and it is used at roundabouts and at midblock crosswalks.
-
18. Where in the United States may a motorcycle ride between lanes of traffic?
Show answer
Answer C: Only where a state has specifically authorized it
Riding between lanes is prohibited in most states and permitted only where a state law expressly allows it, so a rider must know the rule for the state being ridden in.
-
19. What is meant by keeping a space cushion?
Show answer
Answer C: Keeping open space on all sides of your vehicle so you always have somewhere to go
Open space ahead, behind and to the sides gives you time to react and an escape path when a hazard appears, which is the core idea of defensive driving.
-
20. Your right wheels drop off the edge of the pavement onto a soft shoulder. What should you do?
Show answer
Answer C: Ease off the accelerator, hold the wheel straight and steer back gently once you have slowed
Yanking the wheel while the tires are pressed against a pavement lip can throw the vehicle across the road, so slow down first and then make a gentle correction.
-
21. You have begun to move into the next lane when the gap you were aiming for closes. What is the safest action?
Show answer
Answer C: Return to your own lane, cancel the signal and wait for a better gap
An unfinished lane change leaves you in a space that no longer exists, and the lane you came from is still yours.
-
22. You drive onto a section where the top layer has been milled off and the surface is grooved. How will it feel?
Show answer
Answer C: The steering may wander, so hold the wheel firmly and slow down
Grooves cut into the pavement tug at the tires and make the steering feel restless. A firm grip and a lower speed keep the vehicle tracking straight.
-
23. A sign on a long descent points to a RUNAWAY TRUCK RAMP a mile ahead. What is that ramp for?
Show answer
Answer C: Stopping a vehicle whose brakes have failed
An escape ramp climbs into deep gravel or sand to bring a vehicle with failed brakes to a halt, so no one should stop or park in it.
-
24. You come to a place where a storm has dropped a power line across the road ahead. What should you do?
Show answer
Answer B: Stop well back, keep everyone away from it and report it to the police
A downed line may be live and can energize the ground around it, so keep well clear and let the utility or the police handle it.
-
25. Your light turns green and a driver on the cross street enters against a red. What should you do?
Show answer
Answer D: Hold back and let that vehicle go through
Giving up a right of way you are entitled to is the only way to avoid a crash with a driver who has already failed to yield.
-
26. Which surfaces usually offer less grip than the pavement around them when wet?
Show answer
Answer B: Painted markings, metal plates and bridge decks
Paint, steel and bridge decks all shed grip when wet or cold, so brake before you reach them rather than on top of them.
-
27. You have stopped at a stop line but parked cars hide the cross street. What comes next?
Show answer
Answer C: Edge forward to where you can see, stopping again if needed
The legal stop at the line is only the first stop; you then move up slowly to a point where you can see, and stop again if traffic requires it.
-
28. At roughly what speed can hydroplaning begin when a lot of water is lying on the road?
Show answer
Answer C: At speeds as low as about 35 mph
With enough water and less than perfect tread, a tire can start to ride on the water at around 35 mph, well below normal highway speeds.
-
29. A signal on an entrance ramp changes from red to green and lets one vehicle at a time onto the highway. What should you do?
Show answer
Answer A: Stop on the red and go on the green, one vehicle for each green
A ramp meter spaces vehicles out so they join the highway one at a time instead of arriving as a group, and it is a traffic signal like any other.
-
30. A steady red arrow is displayed for your left-turn lane at a two-way intersection. What must you do?
Show answer
Answer C: Stop and remain stopped until an indication permits the turn
A steady red arrow prohibits the movement it points to, so the driver stops and waits for a green arrow, a flashing yellow arrow or another indication that permits the turn.
