#1. When driving on a slippery surface such as snow or ice, you should:

Reduce your speed. Allow extra space between your car and the car ahead. Do not brake or turn suddenly. Use a low gear when going down steep hills. Be careful on bridges and overpasses. These areas freeze first and dry out last.


#2. There is a large truck ahead of you. It signals a right turn. What is the main reason for you to stay back and not pass the truck?

Pay close attention to turn signals, and give large vehicles plenty of room to maneuver and make turns. Large vehicles make wide right turns and sometimes leave an open space to the right just before the turn.

If a large vehicle appears to be turning in one direction, it may actually be turning in the other but first swinging wide.


#3. When following motorcycles on streets with streetcar or railroad tracks, you should:

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.


#4. What is true about seat belts?

Safety belts must be worn by all drivers and passengers age 8 and over. It is the responsibility of the driver to ensure ALL passengers obey the safety belt law.


#5. You are within an intersection waiting to make a left turn. The traffic signal light turns red. What should you do?

If you are within the intersection, continue through carefully. Do not back up or block the intersection.


#6. When making a left turn into a two-way street with multiple lanes, it is generally wrong to:

When making a left turn, do not turn from or enter the right-hand lane. Make the turn so that you enter the passing lane of a four-lane highway. When traffic permits, move to the right, out of the passing lane.

This question asked what is wrong to do.


#7. Does a posted speed limit of 70 mph mean that you may drive 70 mph on that highway under all conditions?

You may drive at the maximum allowable speed only under safe conditions. You must be aware that there may always be dangers present due to pedestrians, traffic, weather, mechanical problems or road conditions.


#8. If your speed is 45 mph, how far will your car travel in three seconds?

If your speed is 45 mph, your car will travel 198 feet in three seconds.


#9. When entering or crossing a road from a driveway in an urban area:

In urban areas, drivers must come to a complete stop when moving out of an alley, building, private road or driveway and before entering the sidewalk area. If there is no sidewalk, stop at a point nearest the street or roadway where there is a view of approaching traffic. After stopping, yield the right of way to pedestrians and all vehicles.


#10. You approach this vehicle from behind. It is keeping an exceptionally low speed. What should you do?

A broken yellow line indicates that passing on the left is permitted when the way ahead is clear. Overtaking and passing should be done with care because of oncoming traffic.


#11. You go to a social event and need to drive a short time after. Which is the best precaution to take?

Drinking even a small amount of alcohol increases your chances of causing a crash. Do not drink and drive.

If you have been drinking, let somebody else drive


#12. What does this pattern on an arrow board mean?

There is a work area ahead. Drive with extra caution.

Arrow boards warn the motorist of an upcoming lane closure, or caution when construction is ahead.


#13. If you are convicted of leaving the scene of a crash that injured another person, it will:

Offenses for which your driver’s license may be revoked include leaving the scene of a crash that killed or injured someone (minimum three-year revocation).


#14. A person can park and leave a car:

Never park or leave your vehicle in front of a driveway, on a bridge or on a crosswalk. Vehicles displaying license plates or parking placards for persons with disabilities may park in spaces reserved for persons with disabilities. The authorized holder of the parking placard or plates must be present and must enter or exit the vehicle at the time the parking privileges are being used.


#15. Driving at night with parking lights instead of headlights is:

When the law requires vehicles to have their headlights on, it is illegal to use only the parking lights.


#16. Compared to other roadway users, motorcyclists:

Motorcycle riders have the same rights and responsibilities as other roadway users.


#17. 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.


#18. You must always stop before a railroad crossing if:

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.


#19. When passing another vehicle on a two-lane highway, you must:

Look ahead and behind to determine when it is safe to pass. Give a left-turn signal so the driver behind you will know that you are about to pull out and pass.


#20. If your car starts to skid, what is the most common cause?

Unsafe speed is the most common cause of skidding accidents.

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.
