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 approaching a stopped school bus on your side of an undivided highway with four lanes. The bus is flashing its red lights. You must:

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.


#2. If you are on the main road when you see this sign:

Merge sign. If you are on the main road and see this sign, be prepared for other cars and trucks entering into your lane.


#3. Bicyclists must ride:

Bicyclists are required to ride with the flow of traffic.


#4. A traffic signal showing a steady yellow light means:

A yellow circular indication warns that the signal is about to change to red. If you have not entered the intersection and can come to a safe stop, you should do so. If you are already in the intersection, you should continue moving and clear it safely.


#5. An Administrative License Suspension is imposed by:

If you are arrested for operating a motor vehicle while under the influence of alcohol or other intoxicating substances and you fail an evidentiary test by having an alcohol concentration over the legal limit, a peace officer will serve you with a Notice of Suspension. This notice is an Idaho Transportation Department imposed administrative driver’s license suspension (ALS).


#6. Your high-beam headlights will normally let you see at least:

High beams allow the driver to see people and vehicles at least 350 feet away. Low beams light the roadway at least 100 feet ahead.


#7. As a safe driving practice you should check your rear-view mirrors:

Avoid a fixed, straight-ahead stare. Check the traffic behind you frequently – several times a minute – so you will know if somebody is tailgating, coming up too fast or trying to pass.


#8. You approach this road sign. What should you expect?

Two-way Traffic.

Keep to the right because you are leaving a one-way street and are entering a two-way street. The sign is also used to remind drivers they are on a two-way road.

Remember, you should drive in the right-hand lane and expect oncoming traffic in the left-hand lane.


#9. If required to file an SR-22 after certain serious offenses (like driving under the influence), this certificate must be on file for:

An SR-22 is a certified statement of liability insurance coverage from your insurer.

If your license was suspended for certain serious offenses, (reckless driving, driving under the influence, etc.) you must provide proof, for three years, that you are able to meet financial obligations arising from any accident.

If you violate Idaho’s no-insurance laws, you will – for a first offense – be required to provide proof of financial responsibility for one year. If you commit a second offense in a five-year period, you will be required to provide proof of financial responsibility for three years.


#10. When proceeding through or turning at an intersection, you should:

When proceeding through or turning at an intersection, always scan the corners of the intersection more than once. An approaching cyclist can easily travel 50 to 100 feet in a few seconds, so what you saw on your first look may change. Looking one last time before proceeding is a good safety practice.


#11. If you hit an unattended vehicle, you must:

You must make a reasonable effort to find the owner of an unattended vehicle or other property damaged in an accident in which you are involved. If the owner cannot be located, leave a note telling about the accident, your name, address, and license plate number. You must also notify police if the damage was more than $1,500 or someone was injured.


#12. Which is true about unattended vehicles on the traveled portion of a highway?

Unattended vehicles on the traveled portion of a highway at any time create a potential danger to public safety and are subject to immediate removal (towing).


#13. Where will you find a sign with this shape?

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.


#14. You exit from a garage and there is a sidewalk before you enter the street. You must:

You must stop immediately prior to driving onto a sidewalk or onto the sidewalk area.

Remember, when entering a street from an alley, driveway, or garage, you must stop and yield to pedestrians and other drivers.


#15. Which is one factor that greatly affects your stopping distance?

You will need more distance for stopping when road conditions are poor. Wet roads can be as dangerous as icy roads. Always reduce your speed in wet weather.


#16. 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).


#17. A HAWK signal is showing a flashing yellow light. What will the next signal be?

HAWK stands for High-Intensity Activated CrossWalk. It is a new kind of signal designed to help pedestrians cross busy streets.

The signal light is unlit until the pedestrian pushes the crosswalk button, then it turns to a flashing yellow light that warns drivers approaching the crosswalk to slow down.

The flashing yellow light is followed by a solid yellow light, telling drivers to prepare to stop. The signal changes to solid red lights indicating to drivers to stop at the stop line.

The light will then begin flashing red. This allows drivers to treat the flashing light like a stop sign. Normal vehicle traffic can resume when the light turns dark again.


#18. An important reminder for safe night driving is to:

At night, your vision is reduced. To make sure you have time to react to danger, always drive slowly enough so you can stop within the distance you can see ahead.

This distance is about 350 feet when using the high beams of your headlights, and about 100 feet when using the low beams.


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

Never start across tracks unless there is room on the other side for your vehicle.

Stop if you cannot cross and completely clear the tracks. Never stop on the tracks.


#20. How does smoking marijuana affect a driver?

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.


#21. What does this sign mean?

This is a regulatory No U-turn sign. It means that you are not allowed to make a U-turn.


#22. If you see a traffic accident ahead and police has arrived, you should:

Do not stop at an accident unless you are involved or if emergency help has not yet arrived. If police and emergency vehicles have arrived, use good judgment. Reduce your speed and drive carefully. Look out for people and equipment in the road. Do not stop or slow down to sightsee.


#23. Which is the first thing you should do when your car starts to skid?

Think before you act. Often, an instinctive reaction, such as slamming on your brakes while skidding, may be the wrong thing to do.

When a skid starts, do not panic, and do not hit the brake. Immediately take your foot off the gas pedal and let the car slow gradually. Look down the road and steer in the direction of the skid. For example, if your rear wheels slide to the right, turn your front wheels toward the right.


#24. Crossing a solid centerline is permitted:

The ONLY time a driver is permitted to cross a double yellow line is when turning left into a driveway or entrance to a business.


#25. Which is true about merging onto a freeway?

Adjust your speed here to match highway traffic. You must blend into the flow of traffic on the freeway’s outside lane. Once you are traveling at the speed of traffic, you can make a simple lane change, merge with the flow of vehicles, and turn off your turn signal.

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.

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.
