1. In a work zone, the flagger's instructions conflict with the pavement markings still visible on the road. Which do you follow?
Show answer

-
4. What should you do before leaving a parked vehicle unattended?
Show answer
Answer C: Set the parking brake, place the transmission in park or in gear, switch off the engine and take the key
Securing the vehicle with the parking brake, the transmission and the ignition prevents it from rolling away and from being moved by someone else.
-
5. You are about to pass a long tractor-trailer on a two-lane road. What should you expect?
Show answer
Answer B: You will need more clear road, since the vehicle is much longer
A tractor-trailer can be 70 feet long, so passing it takes more distance and more time than passing a car at the same speed difference.
-
6. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
7. Illinois law generally requires a bicyclist to ride near the right-hand edge of the roadway. In which situation is a cyclist allowed to move away from the edge and use more of the lane?
Show answer
Answer B: When the lane is too narrow for a bicycle and a vehicle to safely travel side by side
Illinois law allows a cyclist to move away from the right-hand edge when the lane is a substandard width lane, too narrow for a bicycle and a vehicle to travel safely side by side.
-
8. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?
Show answer
Answer D: Slow or stop and let the person reach safety
Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.
-
9. School warning signs use which background and legend colors?
Show answer
Answer A: A black legend and border on a fluorescent yellow-green background
School warning signs carry a black legend and border on a fluorescent yellow-green background, a shade chosen so they stand out from ordinary yellow warning signs.
-
10. A lane control sign over one lane shows both a straight arrow and a left arrow. What does it tell drivers in that lane?
Show answer
Answer A: Either movement may be made from that lane
An optional movement lane control sign lists every movement permitted from the lane, so a driver may choose any arrow shown.
-
11. There is a driveway and a side street between you and the corner where you will turn right. When should you signal?
Show answer
Answer C: After passing the openings, so nobody pulls out in front of you
A signal switched on before an opening tells drivers waiting there that you are turning in, and they may pull out into your path.
-
12. What does this sign tell a driver about the road ahead?
Show answer
Answer A: The roadway changes direction ahead, so speed should be reduced before reaching it
It gives advance notice of a change in alignment so the driver can slow down before entering, since braking inside a bend uses up grip that is needed for steering.
-
13. Your low beams light about 250 feet of road, but at your speed you would need more than that to stop. What is that called?
Show answer
Answer D: Overdriving your headlights
When your stopping distance is longer than the stretch of road your headlights show, you cannot react to anything you finally see. Slow down until you can.
-
14. What is the purpose of carrying a first aid kit in your vehicle?
Show answer
Answer D: It lets you treat cuts and bleeding while the help is on its way
A kit is for simple first aid such as controlling bleeding until trained help arrives, not a substitute for calling for that help.
-
15. Why should heavy objects in the passenger compartment be secured?
Show answer
Answer A: Because loose objects fly forward in a crash and can injure the people
Anything loose keeps traveling at the speed of the vehicle when the vehicle stops, so it strikes the occupants with great force.
-
16. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
17. You are stopped in traffic at a red light when an ambulance comes up behind you with its siren on. What is the correct action?
Show answer
Answer D: Stay put until you can move aside legally and safely
You must not run a red light or make an unsafe move to yield; wait, then pull to the side once the way ahead lets you do it safely.
-
18. A square sign with a red field, a wide white horizontal bar and the words DO NOT ENTER tells a driver that
Show answer
Answer B: the roadway ahead must not be entered from that point
The do not enter sign is posted at the end of a one-way roadway or ramp to keep traffic from driving into it against the flow.
-
19. You and a driver coming from the opposite direction reach a four-way stop at the same time and you are both going straight ahead. What happens next?
Show answer
Answer D: Both of you may move off together, because your paths do not cross each other
Opposing vehicles that are both going straight do not cross paths, so they can move off together once the intersection is clear.
-
20. A sign reads REDUCED SPEED LIMIT AHEAD. What does it tell you?
Show answer
Answer D: A lower limit begins further along the road
The sign gives advance notice so a driver can slow gradually, and the new figure takes effect at the speed limit sign that follows.
-
21. In normal operation, which indication always comes between a green and a red on the same signal face?
Show answer
Answer C: A steady yellow
The yellow change interval must follow every green or green arrow, so a signal can never jump straight from green to red.
-
22. You have stopped on the shoulder of a highway and want to rejoin the traffic. What is the correct way?
Show answer
Answer D: Signal, build up speed along the shoulder, then merge into a gap
Entering a fast lane at a slow speed is what causes the conflict, so the shoulder is used to gain speed before the merge in the same way as an acceleration lane.
-
23. On a two-lane road with a broken yellow center line, may you cross it to turn into a driveway on the left?
Show answer
Answer C: Yes, when it is safe and the oncoming lane is clear
A broken center line may be crossed for a pass or for a left turn into a road or a driveway, once the oncoming lane is clear.
-
24. On a clear day with light traffic, a driver stays far below the maximum this sign sets. What can that cause?
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.
-
25. You reach a red light with a sign reading NO TURN ON RED. What may you do?
Show answer
Answer D: Wait for the green; no turn is allowed while the light is red
That sign removes the usual permission to turn on red at the intersection, so you must wait for a green indication.
-
26. In most states, when are headlights required apart from times of poor visibility?
Show answer
Answer A: From about half an hour after sunset to half an hour before sunrise
Most states require lights from about half an hour after sunset until about half an hour before sunrise, and some simply say sunset to sunrise; lights are also required whenever visibility is poor.
-
27. You have a green left-turn arrow but a pedestrian is still walking in the crosswalk you must cross. What should you do?
Show answer
Answer B: Wait until the crosswalk is clear before turning
A green arrow protects you from other vehicles, but it never removes the duty to yield to a person already in the crosswalk.
-
28. 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.
-
29. Your vehicle has a backup camera. What is the right way to use it?
Show answer
Answer C: Use it as an aid, but still turn and look behind you
A camera has a limited field of view and can be dirty or wet, so it supplements looking over your shoulder and using the mirrors rather than replacing them.
-
30. You are on a four-lane divided highway and a vehicle in your lane is stopped waiting to turn left across the median. What is the normal way past?
Show answer
Answer D: Slow down and go by in the lane to the right when it is clear
On a multilane road the free lane beside you is the lawful place to go past a vehicle waiting to turn, and the median is not part of the roadway.
-
31. Which vehicles are subject to Illinois' diesel vehicle emissions inspection program?
Show answer
Answer A: Diesel vehicles registered for a gross weight of more than 16,000 pounds and at least two model years old, in affected areas
Illinois requires diesel vehicles registered for a gross weight of more than 16,000 pounds and at least two model years old to undergo emissions inspection in affected areas.
-
32. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
33. Rain is heavy enough that you have your windshield wipers running. What else should you switch on?
Show answer
Answer A: Your headlights, so you can see and others can see you
Rain heavy enough to need wipers also cuts how far away you can be seen, so the headlights belong on. Many states write this into law as a wipers on, lights on rule.
-
34. Under Illinois' Road Safety and Fairness Act, how often must a driver aged 79 or 80 renew a driver's license, and is a road test required?
Show answer
Answer C: Every four years, in person, with a vision test but no road test
The Road Safety and Fairness Act keeps the standard four-year renewal cycle for drivers aged 79-80 and requires only a vision test, not a road test.
-
35. A center lane is marked with a broken yellow line on each side and is controlled by overhead lane signals. How is that lane used?
Show answer
Answer A: It carries traffic one way or the other according to the signals
A reversible lane is marked with broken yellow lines on both sides and its direction of travel is set by the lane control signals above it.
