1. A steady green downward arrow is displayed above the lane you are in. What does it tell you?
Show answer
Answer A: You may drive in that lane
A green downward arrow means the lane beneath it is open for travel in your direction.
-
2. A person with a guide dog is standing at the corner facing the street you are about to cross. What should you do?
Show answer
Answer D: Stop well back and wait quietly for them to decide
Blind pedestrians rely on engine sound to judge traffic, so stop back from the crossing and avoid the horn, which only confuses them.
-
3. What do two solid yellow lines down the middle of a two-way road mean?
Show answer
Answer D: Passing is prohibited for traffic in both directions
A double solid yellow line marks a two-direction no-passing zone, so neither direction may cross it to overtake another vehicle.
-
4. What is wrong with steering through a turn using the palm of one hand on the wheel?
Show answer
Answer D: You have less control and cannot correct quickly if something goes wrong
One-handed palming gives poor leverage and slow response. Use hand-to-hand or hand-over-hand steering with both hands so you can react instantly.
-
5. Until what age does Illinois require a child to ride in a rear-facing child restraint system?
Show answer
Answer B: Until age 2, unless the child weighs more than 40 pounds or is more than 40 inches tall
Illinois requires rear-facing restraint until age 2 unless the child weighs more than 40 pounds or measures more than 40 inches.
-
6. You are about to pass a bicyclist on a narrow two-lane road. What is the correct way to do it?
Show answer
Answer A: Wait for a clear gap and move well left, giving the rider wide space
Pass a cyclist as you would a car: wait for clear road, change lane position to leave generous clearance, and return only when the rider is well behind you.
-
7. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
8. Where is a U-turn most clearly unsafe and generally prohibited?
Show answer
Answer D: On a curve or near a hill crest, where other drivers cannot see you
U-turns are barred where approaching drivers cannot see you in time, such as on a curve or near the top of a hill.
-
9. A sign on a divided highway reads Keep Right Except to Pass. What does it require of you?
Show answer
Answer A: Use the left lane only to overtake, then return to a lane on the right
The left lane on such a highway is reserved for overtaking, so a driver who has finished a pass must move back to the right.
-
10. How often must a school bus operating in Illinois undergo a state safety inspection?
Show answer
Answer A: At least every 6 months or 10,000 miles, whichever occurs first
Illinois requires school buses to be inspected at least every 6 months or 10,000 miles, whichever occurs first.
-
11. You are approaching a horse and rider on a country road. What about your horn?
Show answer
Answer C: Do not sound it at all, because the noise can frighten the animal
A startled horse is dangerous to its rider and to you, so pass wide and slow and leave the horn alone.
-
12. A driver ignores this sign and passes on the opposite side. What is the main risk?
Show answer
Answer B: Ending up on the wrong side of a divider, facing traffic coming the other way
The sign settles which side of a fixed divider is the legal one, so taking the other side sends the vehicle into the opposing stream or straight at the obstruction.
-
13. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
14. Well before an intersection, an overhead sign shows a diagram of the lanes with an arrow above each one. What is its purpose?
Show answer
Answer C: To let drivers pick the correct lane in good time
Advance intersection lane control signs display the lane assignment far enough back that drivers can move over calmly instead of at the last moment.
-
15. You are crossing a divided highway with a wide median. How should you treat the two roadways?
Show answer
Answer D: As two intersections, waiting in the median only when your vehicle fits
Each roadway of a divided highway is a separate intersection, and you should wait in the median only if it is long enough to hold your vehicle clear of both roadways.
-
16. The lane you are in is marked with a straight arrow and a right-turn arrow together. What does that mean?
Show answer
Answer D: Drivers in that lane may either go straight or turn right
A lane marked with two arrows serves both movements, so a driver in it may take either one.
-
17. You are turning right on a red light where that is permitted. What does the law require first?
Show answer
Answer B: A full stop, then yielding to traffic and pedestrians
A right turn on red is allowed only after stopping completely and giving way to everyone who has the green, including people in the crosswalk.
-
18. On a long uphill grade a second lane opens on the right and a sign directs slower traffic into it. You are towing a trailer and holding up a line of vehicles. What should you do?
Show answer
Answer A: Move into the right-hand lane and let the faster traffic use the left lane
A climbing lane exists so that slow vehicles can be passed safely, and the slower vehicle is the one that belongs in it.
-
19. When a school bus stops on a one-way Illinois roadway to load or unload pupils, how many lanes of traffic must stop?
Show answer
Answer A: All lanes of traffic, regardless of the number of lanes
On a one-way Illinois roadway, all lanes of traffic must stop for a loading or unloading school bus, regardless of how many lanes exist.
-
20. You want to reverse direction but the street is too narrow for a U-turn. What is the alternative?
Show answer
Answer D: Make a three-point turn, or go around the block in heavy traffic
Where there is not enough width for a U-turn, the three-point turn does the job in stages, and on a busy street going around the block is safer still.
-
21. The vehicle ahead of you has pulled out to pass a truck. May you follow it out and pass as well?
Show answer
Answer B: No, wait until it is done and judge the road for yourself
You cannot see past the vehicle ahead of you, and if it has to abort the pass there is nowhere for either of you to go.
-
22. 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.
-
23. How is the yield sign shaped and colored?
Show answer
Answer C: A downward-pointing triangle with a wide red border and a red legend on white
The yield sign is a downward-pointing equilateral triangle with a wide red border and the legend in red on a white background, an outline used for no other message.
-
24. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
-
25. How should the outside mirrors be aimed to reduce your blind spots?
Show answer
Answer A: Outward, so each one covers the lane beside you rather than repeating the inside mirror
Mirrors aimed too far inward show you the same road three times and leave a large gap beside the vehicle, so aiming them outward shrinks the blind spot.
-
26. Traffic is backed up on the far side of a railroad crossing. What should you do before driving onto the tracks?
Show answer
Answer D: Wait behind the tracks until there is room to clear them completely
Never enter a crossing until you are certain you can drive completely across without stopping, because a vehicle trapped on the tracks cannot get out of a train's way.
-
27. You are following a large truck on a two-lane road and cannot see past it. What should you do before deciding to pass?
Show answer
Answer D: Drop back so that your view of the road ahead opens up
Distance is what buys you a view around a large vehicle, and no decision to pass can be made from a position where you cannot see.
-
28. As a general rule, how far should you travel along a center two-way left-turn lane before you turn?
Show answer
Answer C: Only a short distance, just enough to slow down and wait for a gap
The center lane is for making or preparing a left turn, so you enter it only shortly before the turn and never travel along it as a through lane; several states set a specific limit such as 200 or 300 feet.
-
29. You are starting from a stop on a snowy, icy street and the drive wheels begin to spin. What should you do?
Show answer
Answer C: Ease off the accelerator and start again more gently
Spinning tires polish the surface and dig in. Very gentle pressure on the accelerator, and a higher gear if you have one, gives the tires the best chance to grip.
-
30. This sign leads to a crossing that has no gates and no flashing lights. What does that mean for the driver?
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.
-
31. You have loaded the trunk heavily. Why might oncoming drivers flash their lights at you at night?
Show answer
Answer D: The rear sits lower, so your headlights point higher and dazzle them
Weight in the back tips the vehicle nose up and lifts the beam pattern, so low beams shine into the eyes of drivers coming the other way.
-
32. A power line has fallen across your vehicle after a crash. What should you do?
Show answer
Answer C: Stay inside and wait for utility workers unless fire forces you out
The vehicle body may be energized, and touching it and the ground at the same time can be fatal. If you must leave because of fire, jump clear with both feet together and shuffle away.
-
33. Unless otherwise posted, what is the Illinois speed limit in a city or town area?
Show answer
Answer B: 30 miles per hour
Illinois sets a default of 30 miles per hour in city and town areas and 15 miles per hour in alleys, though municipalities may post different limits.
-
34. Once you are moving, which way of using a navigation device costs you the least attention?
Show answer
Answer B: Listening to the spoken directions
Voice guidance lets you keep your eyes on the road, while anything that needs the screen takes glances that add up over a trip.
-
35. What does Illinois law generally prohibit regarding open alcoholic beverages inside a vehicle's passenger compartment?
Show answer
Answer A: Having any open alcoholic beverage or cannabis in the passenger compartment, unless it is in its original sealed container
Illinois generally prohibits any open alcoholic beverage or cannabis in a vehicle's passenger compartment, except when it remains in its original container with the seal unbroken.
