1. You are about to pass a large truck on a two-lane highway. Which practice is correct?
Show answer
Answer A: Finish the pass without delay and expect wind turbulence beside the truck
Lingering beside a truck keeps you in its blind spot and exposes you to air turbulence. Pass on the left, keep moving, and move back only when you can see the whole truck in your mirror.
-
2. How does heavy cargo on a roof rack change the way a vehicle handles?
Show answer
Answer D: It raises the center of gravity, so the vehicle tips more in turns and needs gentler steering
Weight carried high makes the vehicle lean more and roll over more easily, and extra weight lengthens stopping distance. Drive slower and steer smoothly with a loaded roof.
-
3. You arrive at an intersection where the traffic signals are completely dark after a power failure. What should you do?
Show answer
Answer A: Treat the intersection as an all-way stop and take turns
When a signal is dark or out of order, drivers on every approach must stop and proceed in turn, exactly as at a four-way stop.
-
4. Where should your hands normally rest on the steering wheel?
Show answer
Answer C: On opposite sides of the wheel, near the 9 and 3 positions
Hands placed opposite each other near the middle of the wheel give smooth, balanced control and keep the arms clear of a deploying air bag.
-
5. What does a broken line indicate, whatever color it is painted?
Show answer
Answer C: That crossing it is permitted
A broken line always describes a permissive condition, and the color then tells the driver whether the traffic beyond it runs the same way or the opposite way.
-
6. 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.
-
7. Why is a U-turn on a one-way street a problem?
Show answer
Answer A: You would end up facing the wrong way against all the traffic
Every lane of a one-way street runs the same way, so turning around leaves you driving head-on against all of the traffic.
-
8. Crossing a parking lot on a hot day, you see a young child alone in a locked car. What should you do?
Show answer
Answer A: Call 911 right away and stay with the vehicle
The inside of a parked car can reach lethal temperatures within minutes, so a child left alone in one is an emergency.
-
9. The divided highway ends warning sign means that
Show answer
Answer D: the median separating the directions ends and the road returns to two-way operation
Beyond this sign opposing traffic is no longer separated by a median, so the driver must keep right and expect vehicles approaching in the adjacent lane.
-
10. How long must an Illinois driver aged 15 to 17 hold an instruction permit before obtaining a driver's license?
Show answer
Answer C: At least nine consecutive months
Illinois requires an instruction permit issued to a driver aged 15 to 17 to be held for at least nine consecutive months before a driver's license may be issued.
-
11. An orange sign reads RIGHT LANE CLOSED AHEAD. What is the correct response?
Show answer
Answer A: Move left in good time and keep a steady pace
The sign is placed well before the taper so that drivers can merge smoothly rather than braking hard where the lane actually closes.
-
12. A motorcycle ahead of you has its turn signal blinking but continues straight through several intersections. What is the likely explanation?
Show answer
Answer D: Motorcycle signals often do not cancel themselves after a turn
Many motorcycle turn signals are not self-cancelling, so a rider may leave one on by mistake. Wait until the rider actually starts to turn before you act on the signal.
-
13. How much following distance should you keep behind a motorcycle?
Show answer
Answer C: At least three to four seconds
A motorcycle can slow or stop very quickly and is easily upset by a surprise, so allow three to four seconds instead of the usual car gap.
-
14. A person in a wheelchair is traveling in the roadway because the sidewalk is blocked by construction. What should you do?
Show answer
Answer B: Pass slowly with plenty of room, or wait
A blocked sidewalk leaves the person no choice but the road, and a chair cannot move aside quickly, so pass wide and slow or wait for room.
-
15. 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.
-
16. 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.
-
17. Where should the lap part of the seat belt sit?
Show answer
Answer C: Low and snug across the hips, touching the tops of both of the thighs
The hip bones can take crash forces, but the abdomen cannot, so the lap belt goes low and tight across the hips.
-
18. Your car is sinking after leaving the road into deep water and two children are in the back. In what order should you act?
Show answer
Answer D: Free yourself from the belt first, then release the children, the oldest one first
You cannot help anyone while you are still belted in, and the oldest child released first needs the least help getting out.
-
19. 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.
-
20. You want to turn left at an intersection with no signs or signals and a vehicle is coming straight toward you from the opposite direction. What must you do?
Show answer
Answer C: Yield and turn after the oncoming vehicle has passed
A driver turning left always gives way to oncoming traffic that is close enough to be a hazard, whether or not the intersection is controlled.
-
21. A driver's blood alcohol concentration is below the legal limit, but the driver is visibly impaired. Can the driver be arrested?
Show answer
Answer C: Yes, driving while impaired by alcohol is an offense at any concentration
The per se figure, 0.08 percent in most states and 0.05 percent in Utah, is the level at which impairment is presumed. Impairment shown by driving behavior and field tests is enough on its own, because alcohol affects skills well before that number.
-
22. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
23. What is sensible when you drive in an unfamiliar town for the first time?
Show answer
Answer C: Drive a little slower and give yourself more time to read the signs
In unfamiliar surroundings you need longer to take in signs, junctions and markings, and lower speed buys that time.
-
24. Warning signs such as stop ahead, yield ahead and signal ahead are installed mainly where
Show answer
Answer B: the traffic control device cannot be seen from far enough away
These advance warning signs are used when a crest, curve or obstruction keeps the stop sign, yield sign or signal from coming into view in time for a driver to react.
-
25. Some toll facilities use signs and markings with a purple background or a purple stripe. What do they identify?
Show answer
Answer D: Lanes reserved for vehicles with an electronic toll account
Purple is assigned to lanes and ramps restricted to vehicles with a registered electronic toll collection account, so drivers without one must stay out.
-
26. A large electronic advertising sign beside the road catches your eye. What should you do?
Show answer
Answer A: Glance briefly and return your eyes to the road
Bright changing displays are designed to hold attention, so treat them like any roadside object and give them no more than a brief glance.
-
27. Under Illinois' basic speed law, in which of these situations must a driver reduce speed below the posted limit even without a separate warning sign?
Show answer
Answer D: When approaching and going around a curve, or approaching a hill crest
Illinois' basic speed law requires drivers to reduce speed when approaching and going around a curve or approaching a hill crest, among other listed hazards.
-
28. May you park across the entrance to a fire station?
Show answer
Answer D: No, an emergency exit must never be blocked
Emergency vehicles must be able to leave the moment a call comes in, so their entrances and exits are kept clear at all hours.
-
29. Why are motorcycles so often missed by other drivers?
Show answer
Answer C: Their narrow shape is easily hidden in traffic
A motorcycle presents a narrow outline that disappears behind pillars, mirrors and other vehicles, and it is harder to judge its speed and distance.
-
30. As a driver keeps drinking, in what order are driving abilities usually lost?
Show answer
Answer C: Judgment, then vision, reaction time and coordination
Alcohol reaches the parts of the brain that handle judgment first, and only later does it visibly affect sight, reactions and muscle control.
-
31. An entrance ramp joins a highway just before an exit ramp leaves it. What should you expect in that short section?
Show answer
Answer D: Vehicles crossing paths as some enter and others leave
In a weaving section entering traffic moves left while exiting traffic moves right over the same short stretch, so lane changes there need extra room and extra care.
-
32. Which sign tells you that the vehicles ahead are part of a funeral procession?
Show answer
Answer C: Headlights burning in daylight, with small flags or markers on the vehicles
Processions are normally identified by daytime headlights, hazard lights and flags or windshield markers, not by emergency lights or sirens.
-
33. May you park in front of a public or private driveway?
Show answer
Answer A: No, blocking a driveway is prohibited even for a short time
Parking in front of a driveway blocks the property owner from entering or leaving, and the prohibition does not depend on how long you stay.
-
34. What is the only reliable remedy for a driver who is sleepy?
Show answer
Answer A: Sleep
Caffeine, fresh air and noise may make you feel alert for a few minutes, but they do not remove the need for sleep. Stop somewhere safe and rest.
-
35. 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.
