#1. When driving in fog, it is not advisable to:

If you must drive in fog, reduce your speed. Turn off the cruise control if in use and increase your following distance. Drive with your headlights set on dim (low beams), or use fog lights. Never overdrive your headlights.


#2. You may park on the roadside of another parked vehicle (double park):

Stopping, standing or parking is prohibited on the roadway side of any parked vehicle (double parking).


#3. If you are involved in a crash with injuries, you must notify the police:

Notify the police immediately. Many towns and cities require a report if a crash occurs within their limits. If an officer is not at the scene of the crash, a report must be made at the nearest police station as soon as possible. If in a rural area, the county sheriff or Illinois State Police must be notified. If the driver is unable to make the report and there is a passenger, the passenger must make the report.


#4. If you see a pedestrian with a white cane at a crosswalk, you should:

You must always give blind persons the right-of-way, even if the traffic signals or other right-of-way rules are not in their favor.


#5. Where is passing another vehicle on two-lane, two-way roads not allowed?

Passing on a two-lane, two-way roadway is not allowed:

  • On a hill or curve where it is not possible to see oncoming vehicles.
  • Within 100 feet of an intersection or railroad crossing.
  • When the view is blocked within 100 feet of any bridge, viaduct or tunnel.
  • When a vehicle has stopped at a crosswalk or intersection to allow a pedestrian to cross.
  • In a construction zone. All constructions zones in Illinois are no passing zones.
  • In an area marked for no passing by a solid yellow line on your side of the center of the roadway or a do not pass or no passing zone sign.

#6. True or false? When entering a highway construction area, a driver should discontinue wireless/cellphone use.

Don’t use your cellphone in work zones. Illinois law requires motorists to discontinue wireless/cellphone use (unless using a hands-free device that may include the use of a single-sided headset).


#7. What is true about seat belts?

In a collision, seat belts reduce the force of impact against the interior. Seat belts also keep you inside the car and safer. They help you stay in position to control your car.


#8. Drivers may pass on a two-lane roadway marked with a single solid yellow line on their side of the center line.

No passing lines are solid yellow lines on roads where traffic moves in opposite directions. The lines indicate zones where passing is not allowed. When there is a solid and a broken yellow line separating two lanes of traffic moving in opposite directions, a driver may pass only when the broken yellow line is nearest the driver’s lane.


#9. When turning left from a two-way street onto a one-way street, you should complete the turn in:

To turn left from a two-way road onto a one-way road, approach the turn with your left wheels close to the center line of the road. Make the turn before reaching the center of the intersection, and enter the left lane of the one-way road.


#10. When passing a stopped emergency vehicle with flashing lights activated, you should:

When approaching a stationary emergency vehicle using visual signals, Illinois law requires motorists to yield, change to a lane away from the emergency vehicle and proceed with caution. If a lane change is not possible, reduce speed and proceed with caution.


#11. You approach a railroad crossing. There is heavy traffic ahead. You must stop before the crossing when:

Never move onto a railroad track unless you are certain you can drive across safely. Be careful not to get trapped on railroad tracks by a line of vehicles backed up by a traffic signal.


#12. When you meet a truck coming from the opposite direction on a two-way road, you should:

When you meet a truck coming from the opposite direction, keep as far as possible to the right side of the road to avoid being sideswiped and to reduce the wind turbulence between you and the truck. The turbulence pushes vehicles apart. It does not suck them together.


#13. If you have a tire blowout while driving, you should:

A thumping sound may be a warning of a blowout. If this happens, ease your foot off the gas pedal and keep a firm grasp on the steering wheel. Do not brake suddenly. When you have full control, pull safely off the roadway and check your tires.


#14. Of all motorcycle crashes, about 20 percent occur at intersections.

More than 50 percent of all motorcycle crashes occur at intersections. The most common situation occurs when an oncoming automobile makes a left turn in front of a motorcycle. A vehicle driver should watch for motorcycles before turning and yield the right of way. A driver should be particularly careful when making a left turn across lanes of oncoming traffic and should wait to be sure of the motorcycle operator’s intent before proceeding to make a left turn.

Drivers involved in crashes often report not seeing the motorcycle or seeing it too late to avoid a collision.


#15. Why is it important to know what kind of braking system your vehicle has?

Knowing how to apply your brakes in an emergency situation may save your life. Conventional and anti-lock brakes (ABS) are used differently, so it is important to know what kind of braking system your vehicle has.


#16. This sign (a steady yellow X) means:

Special lights sometimes are used over each lane on highways and expressways. They are used most often to change the flow of traffic during certain hours of the day.

A green arrow means the lane may be used, but all other signs and signals must be obeyed.

A steady yellow X means the signal is going to change to red. Leave this lane safely before the red X appears.

A red X means the lane is closed. Never drive in this lane.

A flashing yellow arrow or flashing X means that the lane may be used for approaching and making a left turn. Such a lane may also display white two-way left-turn arrows or a white one-way left-turn arrow.


#17. What should you do when following a motorcycle on gravel roads?

A driver should allow a greater following distance when behind a motorcycle so the motorcyclist has enough time to maneuver in an emergency. Motorcycles react differently to traffic, weather and road conditions than cars. Riders may respond in ways a vehicle driver does not expect. Wet or icy roads impair a motorcyclist’s ability to brake and maneuver. Wind gusts, both natural and those created by large passing vehicles, can move a motorcycle across an entire lane if the rider is not prepared. Potholes or railroad tracks often require motorcyclists to change positions within their lane. Gravel roads decrease traction and may cause a rider to slow down or brake where a car would not.


#18. Unless otherwise posted, what is the legal speed limit in school zones?

Speed Limit in school zones is 20 mph (school days between 7 a.m. and 4 p.m. when children are present and signs are posted).


#19. What does the Implied Consent law mean?

When driving on Illinois roadways, you automatically consent to submit to certain tests. These can include breath, blood and/or urine tests to determine if you were drinking or using any other drug or intoxicating compound before or while driving. A doctor or registered nurse must perform the blood test. You may have a qualified person of your own choosing administer more tests at your own expense.


#20. When approaching another vehicle from behind at night, at what distance should you dim your headlights?

Bright lights must be dimmed 500 feet before meeting an oncoming vehicle or 300 feet before passing a vehicle.

The second part has 20 multiple-choice or true-false questions about Illinois traffic laws and safe driving techniques.

This practice test addresses the second part of the written examination.

How hard is the Illinois Permit Test?

The failure rate on the Maryland permit test is about 10%, which means that only one out of 10 fails the test the first time.

Test difficulty is graded very easy, which doesn’t mean that should not do your best to prepare for the examination.

How to Study for the Illinois Written Test

1   Download the manual Rules of the Road .

“Rules of the road” describes all rules and traffic laws you must learn to pass your written knowledge examination. All answers to test questions are found in this manual.

You can get your copy from any service center or download a PDF-version online.

The booklet is written with the knowledge examination in mind. The language is simplified and does not cover all laws or explain every possible situation that you may face while driving on Illinois highways. It is intended as a tool for new drivers to help them learn the essential driving rules and help them pass the knowledge test.

Everything in the manual is there for a reason and you should expect questions to be drawn from all parts of the manual.

2   Use practice tests as a supplement to the manual.

These practice tests are a supplement to the manual. They don’t replace the manual.

It may be tempting to skip reading the manual and try to learn all rules from the practice tests only.

Even if practice tests and cheat sheets cover all important items on the written examination, test questions and answers don’t always put facts in a context. By reading the manual you will get a better understanding of safety rules and why you should use them.

This practice test and the signs identification test are randomized, which means that questions are drawn from a larger bank of test questions. Every time you take the test it will be slightly different and show you new questions.

Don’t forget to take both the sign identification test and the rules test when you prepare for your exam.

3   Give it time.

Whenever you learn something new, your brain needs time to absorb all the new information.

The more you spread out your study sessions over time, the better the information will stick for the exam and for your future driving.

You should also try to be active when studying for your permit test.

By quizzing yourself or have someone else ask questions, you can answer with your own words which improves learning. It is also an advantage to engage in discussions about traffic laws. Again, you will be able to put your own words to important facts about driving

Here are some common subjects you may want to discuss in a classroom or with family and friends:

    What are some major contributory factors to accidents?
    Why do teen drivers have a higher accident rate?
    What does the right of way mean?
    What is distracted driving?

What You Should Know about the Test

  You are allowed three attempts to pass.

Within one year from the date you paid the application fee you have three attempts to pass the knowledge test. A new application fee is required for additional attempts.

  Don’t try to cheat.

An examiner will give you a warning if you bring papers or books to the testing area. They will also interfere if you pick up your cell phone while taking the exam. Taking photos of test questions is considered cheating.

If you are found cheating, the test is marked as a failure and you will be prohibited from retaking it for 30 days.

Taking the test for another person is a criminal offense punishable by a fine and a mandatory minimum seven days in jail.

  There is no time limit.

The test is not timed, and the average test taker finishes in about 15 minutes. It still gives you plenty of time to read every question twice.

Test takers who fail the test often argues that they didn’t read a question all the way through and picked the wrong answer by mistake.

It is a good idea to carefully read every question and all choices. Don’t be overconfident and pick the first answer that looks right. Check to make sure your answer makes sense.

  Aim for a passing score on both parts of the test.

New drivers usually fails on the second part of the test. Use practice tests until you can comfortably reach a full score on both parts.

  It may not be over just because you passed.

You must take a knowledge test every 8 years to renew your license, unless you have a clean driving record with no traffic convictions.

Bookmark these tests and you can return to them when it is time to take the exam again.
