Great! That is a passing score on the Idaho knowledge test. Try again?

New test – new questions

Sorry, this is not a passing score on the Idaho knowledge test. Do you want to try again?

New test – new questions

#1. You are driving on a highway posted for 60 mph. Traffic around you is traveling at 70 mph. You may legally drive:

Your speed should be no faster than 60 mph. It is your responsibility to observe and obey the speed limits.

Continue

#2. At a railroad crossing, trains must be given the right-of-way:

Railroad crossbuck signs can be found at most crossings. They have the same meaning as a yield sign. Trains cannot stop, cars can. It is up to you to protect your life and the lives of your passengers at a railway crossing. The stopping distance for a 150-car freight train traveling 50 mph is 7,000 feet or 1 and 1/3 miles.

Continue

#3. If you see this sign beside your lane:

The Right Turn Only sign tells you that you can only turn right from this lane.

Continue

#4. What does this sign mean?

Cattle crossing.

This sign indicates a point where the stock may cross the road.

Continue

#5. Before placing a rear-facing car seat in the front seat, you must make sure that:

Children in rear-facing car seats should NEVER ride in front of an active passenger air bag.

A child in a rear-facing child-restraint system may only be placed in the front seat if the front passenger air bag is deactivated.

Continue

#6. How do you check your blind spots while driving?

Blind spots are areas near the left and right rear corners of your vehicle that are not visible in your mirrors.

Never rely on your mirrors alone. Before you make any move to the side, quickly turn your head to see if your blind spot is clear. Also avoid driving in someone else’s blind spot. It is as important for other drivers to see you as for you to see them

Continue

#7. This sign is often placed:

Slippery when wet.

Road ahead becomes slippery in wet weather. Slow down under these conditions.

This sign is often located near bridges and overpasses. Ice may form sooner or remain on bridges and overpasses longer, since they are exposed on their undersides and are deprived of ground warmth.

Continue

#8. If it feels like your tires have lost contact with the road you should:

If you are about to drive over a slippery area or you think your car has started to hydroplane:

  • Keep moving in a straight line.
  • Slowly take your foot off the gas pedal.
  • Do not try to stop or turn quickly until your tires are gripping the road again.
Continue

#9. During a light rainfall, when are road pavements usually most hazardous?

Remember, roads are more dangerous at the start of a light rain when road oil and water mix to form a greasy film on the road.

Continue

#10. A school bus with flashing red lights is stopped on the other side of a four-lane roadway with a center turning lane. What should you do?

Stop for a school bus that is loading or unloading students. On a two-lane road, both following and oncoming traffic must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended. You must remain stopped until all children are clear of the roadway and the bus moves again.

On a highway with two or more lanes going each direction, oncoming traffic is not required to stop when meeting a school bus.

Continue

#11. Idaho law requires that you turn on headlights:

Turn on your headlights when driving at night (between sunset and sunrise), or when visibility has been reduced to below 500 feet.

Continue

#12. The holder of a Supervised Instruction Permit (SIP) must be accompanied by a licensed driver who is:

While you are operating a vehicle under the Supervised Instruction Permit (SIP), you must be accompanied by a supervising valid licensed driver at least 21 years old who is occupying the seat beside the driver (no other passengers are allowed in the front seat).

Continue

#13. Never back your car:

Whenever possible, avoid backing in traffic. If you have passed your exit on an interstate, never back or try to turn around. Go on to the next exit.

Continue

#14. When passing another vehicle, you may exceed the speed limit:

Always obey speed limit signs. It is illegal to exceed the speed limit when passing.

Continue

#15. Pedestrians crossing at street corners should be given the right-of-way:

Remember to stop or slow down at an intersection when necessary to yield right-of-way to a pedestrian crossing within a marked or unmarked crosswalk.

Continue

#16. If you are preparing for a right turn and a bicyclist is ahead of you:

If you are preparing for a right turn and a bicyclist is ahead of you, do not assume that you can beat the bicycle to the turn. Misjudgment can result in a broadside crash called the right hook. Avoid right-hook crashes by slowing and remaining behind the bicyclist until he rides past the point where you will turn. On streets with bike lanes, remember that you are turning across a dedicated travel lane. Always look for and expect bicyclists.

Continue

#17. You have stopped at an intersection. The traffic light turns green, but there are still vehicles in the intersection. You should:

Remember, you may proceed only if the intersection is clear. You should not enter the intersection unless there is sufficient space on the other side of the intersection for your vehicle to completely pass through, so you are not blocking the intersection, regardless of a traffic control signal to proceed.

Continue

#18. When can you legally park your car in front of a private driveway?

Parking is not allowed in front of a public or private driveway (Idaho Statutes Chapter 6, 49-660).

Continue

#19. Anti-lock brakes are of most use when you are:

Be sure to read the vehicle owner’s manual on how to use the anti-lock braking system (ABS). Anti-lock brakes allow you to retain full steering control during hard braking and on slippery surfaces.

During an emergency stop that requires hard braking, apply continuous pressure on the brake pedal. Do not pump the brake pedal as this will defeat the system’s design, reduce the effectiveness of the ABS, and increase the distance required to stop the vehicle.

Do not be concerned by the noise and pulsation, because this is normal for ABS.

Continue

#20. The use of marijuana often affect a driver's:

Marijuana is a mild hallucinogen that delays a driver’s response to sights and sounds so it takes longer to react to a dangerous situation. Marijuana causes a severe loss of night vision that is compounded by vehicles with tinted windshields. Together, the two can cause a combined loss of up to 70% of night vision.

Continue

#21. Round signs always indicate a:

Round sign black on yellow is used as an advance warning that you are approaching a highway-rail intersection. When you come to this sign, slow down.

You should learn to recognize road signs by color and shape as well as the messages or symbols they carry.

Continue

#22. Signals and directions from a flag person in a construction zone:

Traffic control devices include traffic signals, signs, and pavement markings. Traffic control may also be provided by law enforcement officers, highway personnel or school crossing guards. You must obey directions given by them – even when they conflict with existing signs or signals.

Continue

Always signal for at least five seconds before making a lane change or exiting a freeway.

Continue

#24. A vehicle carrying this sign:

All slow-moving vehicles must display the approved emblem for slow-moving vehicles. This sign has a red perimeter and orange center and is primarily on off road vehicles (implements of husbandry, construction equipment, etc.).

When you are approaching a slow-moving vehicle, you should slow down and approach the vehicle with caution.

Continue

This Idaho Practice Test

This practice test is designed to help you study for and pass the knowledge examination for a Class D (Non-Commercial) license or instruction permit in Idaho.

It has 25 questions drawn from a large bank of DMV questions and answers. Each one is specific for the traffic laws in the state of Idaho. It is, however, shorter than the real knowledge test. It is recommended that you take at least a handful of tests to cover all items in the driver’s manual.

After each question, you will be shown the correct answer. In case your answer is incorrect, there is also a brief explanation to the correct answer. Use the explanation to look up more information in the Idaho Driver’s Manual.

Remember, the purpose of the real examination and this Idaho practice test is to check your knowledge of Idaho traffic laws, highway signs by shape and symbol, traffic signals, pavement markings, and equipment required on motor vehicles.

It is not designed to be a cheat sheet and it may not be inclusive of all questions asked on the official knowledge test. Be sure to always study the Idaho Driver’s Manual before taking the official test.

The practice test, however, help you prepare as much as possible and predict how likely you are to pass the real knowledge examination.

Idaho Driver's Handbook

1   Get the Driver’s Manual

Your first step is to get the latest version of the Driver’s Handbook from itd.idaho.gov. You should use the practice tests to verify your progress only after studying the manual. Do not use the practice test as a replacement for the manual.

You can find all questions and answers you need to pass the written test for a class D license or instruction permit in the Driver’s Manual. It remains your best friend when studying for your first instruction permit.

We help you pass your Idaho Knowledge Test

Aim for a High Score on Each Practice Test

The number of questions on the real test in Idaho is 40 and the passing score is 85%, which is higher than in many other states. Only Maryland and Virginia have higher passing scores

You must correctly answer 34 out of the 40 questions, which means you can only miss 6 of them. In combination with a poor designed test and a high passing score, Idaho knowledge test can be one of the hardest to pass, especially if you haven’t completed a classroom course.

This is why you should aim for the highest possible score on the practice tests. Take as many tests as you need, as often as you like.

On each test, you should make sure you truly understand why an answer is correct and why other options are incorrect.

Known Issues with the Idaho Knowledge Test

Idaho DMV tend to use four choices to each test questions. It is usually difficult to develop more than three plausible alternatives on a DMV test, which means that the fourth choice can be nonsense. This makes the test longer without making it better. On a lengthy test, it can be easy to skip reading all of the choices carefully enough.

Idaho DMV also has a disclaimer at the beginning of the test saying that there may be more than one correct answer and that you must select the best answer.

This is due to the fact that they still use “All of the above” as one alternative. In this type of question, all of the alternatives can be correct.

A nervous test taker may identify the first alternative as correct and read no further.

The same hold true for “Both of the above”.

Remember to always read through all choices. Often, all of the choices are actually correct – but not always!

You may also see “None of the above” as the last choice. This is also considered a bad testing design since it doesn’t check if you know what the correct answer is.

Even if it is less common, you may see a negative question that contains the word not or never. With such a question you must look for an incorrect statement. It is easy to forget this and pick the correct statement instead.

You can overcome these flaws by not rushing through the test, being alert, and make sure you read everything.

More about the Idaho Knowledge Test

The test is available in English, Arabic, Chinese, Farsi, French, Korean, Russian, Serbo-Croatian, Spanish, Vietnamese and ASL (American Sign Language).

It is a closed-book test, which means that you cannot use any kind aids (written, audio, or electronic) while taking the exam.

If you fail the knowledge examination, you must wait at least three days before you can take it again. A new fee is required each time you attempt the test.

Who Must Take the Idaho Knowledge Test?

All new drivers applying for an original driver’s license must pass the knowledge exam.

If you are under 17 years, you must successfully complete a driver training program and comply with the requirements of the Graduated Driver Licensing (GDL) Program. After the supervised instruction period, you must take and pass the written knowledge test before receiving your driver’s license.

If you are 17 years or older, the GDL requirements don’t apply. You start the application process by taking the written knowledge test and a vision screening at a county sheriff’s office.

When transferring from another state, U.S. Territory, or the District of Columbia, you must pass a Class D written knowledge test, even if you have been licensed in Idaho before. Unlike many other states, the written DMV test is not waived for drivers who hold an out-of-state driver’s license.

You must also pass all tests if you hold a foreign driver’s license.

If you let your Idaho Driver’s license expire for 25 months or more, you must also take the knowledge test again.



Idaho Graduated Driver’s License (GDL) program

Anyone under 17 years who applies for their first driver’s license in Idaho must successfully complete an approved driver’s training program and comply with the requirements of the GDL Program.

Unlike other states, Idaho does not require you to pass the written test before issuing a permit under this program (the test comes later).

The first permits are known as the Driver Training (DT) permit and the Supervised Instruction Permit (SIP). They allow anyone at least 14 1/2 years and under 17 years of age to attend any public school or private driver’s training program. You must have your DT permit before taking any DT class.

The training program consists of a required 1,800 minutes (30 hours) of classroom instruction, 360 minutes (6 hours) of in-car observation in a DT car, and 360 minutes (6 hours) of behind the wheel driving with a DT instructor.

While you are enrolled in a training class, the DT permit allows you to drive only while supervised by a training instructor. When you have successfully completed the program, the instructor will release the permit and it know becomes a Supervised Instruction Permit.

In this next phase, you can practice your driving skills when accompanied by any licensed driver who is at least 21 years and who is occupying the front seat beside you (no other passengers are allowed in the front seat).

While You Hold an Idaho Supervised Instruction Permit

You cannot drive alone. You must always be supervised by an adult at least 21 years with a valid driver’s license.

All passengers must wear seat belts or child restraints. Only the supervising driver can sit beside you in the front seat.

You must observe all laws regarding alcohol and other intoxicating substances.

You must complete a minimum 6-month, violation-free supervised instruction period and log at least 50 hours of driving practice. 10 of these 50 hours must be at night.

If you are convicted of violating any traffic laws while you practice driving under this program, the SIP will be canceled. After a cancellation, you must reapply for a new SIP. The 6-month period of supervised driving starts over again.

Idaho Driver's License

Only after meeting all of these requirements under GDL will you be allowed to take the Idaho knowledge test.

If you pass the knowledge test, you can schedule your road skills test.

After passing all tests, DMV will issue an Idaho Driver’s License.
