Great! That is a passing score on the Idaho knowledge test. Try again?
Sorry, this is not a passing score on the Idaho knowledge test. Do you want to try again?
#1. 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.
#2. When an emergency vehicle with flashing lights approaches you in the opposite lane on an undivided highway, you should:
When being approached by an emergency or police vehicle sounding a siren or flashing red or blue lights, you must immediately pull to the nearest curb or the edge of the roadway where it is legal to park and stop. Remain stopped until the emergency vehicle has passed ahead of you.
Remember, you must stop clear of any intersection, including a roundabout. Idaho Statutes 49-625.
#3. How does alcohol affect you?
Alcohol dulls the parts of your brain that control inhibition, judgment, and self-control. After two to four drinks, alcohol begins to impair your reaction time, coordination, and balance. Your vision and ability to judge distance suffers too, making it harder to react to dangers ahead. By making you feel good, alcohol may also give you false confidence. In heavy doses, alcohol can be a mood changer producing sudden shifts in mood all the way from elation to anger.
#4. Before exiting a freeway, you should signal for at least:
Proper signaling may prevent a rear-end collision. Always signal for at least five seconds before making a lane change or exiting a freeway.
#5. When you approach a curve that obstructs your view, you should:
When driving in the mountains, you should stay close to the right edge of the road to be away from oncoming traffic. Sound the horn when approaching any curve on a narrow road where the view is obstructed.
#6. You approach a stopped school bus with flashing red lights from the opposite direction on a roadway with two lanes in each direction. 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 clear 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.
#7. To avoid getting accidentally trapped on a railroad crossing, you should:
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.
#8. You go slower than the average traffic speed on a two-lane highway. Three or more vehicles follow you closely. What should you do?
Any vehicle traveling slower than the normal speed of traffic delaying three or more other vehicles in a rural area or on a two-lane highway must turn off the road wherever safe to let the other vehicles pass.
#9. When entering a freeway from an acceleration lane, you must blend into the flow of traffic:
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.
#10. What does this sign mean?
Low clearance.
When a bridge has an overhead clearance less than 14 feet, this sign is posted indicating the actual legal overhead clearance of a bridge or elevated structure.
#11. When making a left turn at an intersection:
Signals must start at least 100 feet before you turn in business or residential areas.
#12. You approach this road sign. What must you do ahead?
Pedestrian crossing. Watch out for people who might walk or run in front of you. Pedestrians have the right of way and you may have to stop for them. The color of this may be fluorescent yellow/green or yellow.
#13. Parking on the roadside of another parked vehicle (double parking):
Parking is not allowed on the street side of any parked vehicle. (This is known as double parking.)
#14. The best way to avoid last-minute moves when driving is to:
To be a defensive driver, you have to see what is going on. Avoid a fixed, straight-ahead stare that may let you drift off in daydreams. Keep your eyes moving and learn to read the road. Look ahead, to the sides, and behind.
#15. Which is the best method to improve safety when driving at night?
Night driving is more dangerous than daytime driving. You base about 90 percent of your driving choices on what you see. 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.
#16. Which is one factor that significantly affects your stopping distance?
Bad weather can make it harder to see and roads slippery. You will need more distance for stopping when weather conditions are poor.
#17. What does this sign mean?
No turns from this lane. You must go straight through.
#18. From left to right, traffic lights are:
Vertical traffic lights have a red light at the top, a yellow light in the middle, and a green light at the bottom.
Horizontal traffic lights have a red light on the far left, a yellow light in the middle, and a green light on the far right.
#19. You should never stop at the scene of an accident unless:
Someday you may come upon a traffic accident where there are serious injuries and people need help. If police or medical help is already there, do not stop. Move on as officers direct.
#20. In Idaho, car tires must have a minimum tread depth of:
Each tire must have at least 1/32 of tread groove.
Most states require a minimum of 1/16 (2/32) inch tread depth.
#21. What is the background color of a motorist services sign like this?
Guide signs are either white on green for directional and distance, white on blue for motorist services, or white on brown for cultural, historical, or scenic points of interest.
#22. The minimum amount your liability insurance must cover for the injury or death of two or more people is:
All motorized vehicles operated on Idaho roadways, whether registered or not, must carry liability insurance providing the following minimum coverage:
- $25,000 for injury or death of one person.
- $50,000 for injury or death of two or more people. and
- $15,000 for property damage.
The certificate or proof of liability insurance (paper or electronic) must be carried by the operator or be present in every motor vehicle operated within Idaho.
#23. You want to turn left ahead. There is a shared left turn lane in the center of the road. What should you do?
Do not move into the lane too soon. The longer you stay in the lane, the more likely you will meet someone coming in the opposite direction. Do not use any other lane for the turn.
#24. If you need glasses to read traffic signs and vehicle number plates, you must wear your glasses:
If contact lenses or glasses are used to pass the screening, they will be required while driving.
#25. A funeral procession is proceeding through a red traffic-control device and crossing your path at an intersection. What should you do?
You may not enter an intersection when the procession is proceeding through (regardless of the color of the traffic light) unless you can do so without crossing the path of the procession. Always give funeral processions the right of way.

This Idaho Practice Test
We have designed these practice tests 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 to the traffic laws in the state of Idaho. It is, however, shorter than the actual knowledge test. We recommend taking at least a handful of tests to cover all items in the driver’s manual.
After each question, you will see the correct answer. If you answered a question incorrectly, there is a brief explanation for each question. Use the explanation to find more information in the Idaho Driver’s Manual.
Remember, the actual examination and this Idaho practice test aim to check your knowledge of Idaho traffic laws, highway signs by shape and symbol, traffic signals, pavement markings, and equipment required on motor vehicles.
A practice test is not a cheat sheet and does not include all questions on the official knowledge test. Before taking the official test, you must study the Idaho Driver’s Manual.
The practice test, however, helps you prepare as much as possible and predict how likely you are to pass the Idaho knowledge examination.
1 Get the Driver’s Manual
Your first step is to get the latest version of the Driver’s Handbook from itd.idaho.gov. It would help if you only used the practice tests to verify your progress after studying the manual. Do not use the practice test as a replacement for the manual.
In the Driver’s Manual, you can find all the questions and answers you need to pass the written test for a class D license or instruction permit. It remains your best friend when studying for your first instruction permit.
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%, higher than in many other states. Only Maryland and Virginia have higher passing scores
You must correctly answer 34 out of the 40 questions, meaning you can only miss 6. With a poorly designed test and a high passing score, the Idaho knowledge test can be one of the hardest to pass, especially if you haven’t completed a classroom course.
It will help if you 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 tends to use four choices for each test question. 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.
Idah still uses “All of the above” as one alternative, meaning all alternatives can be correct, a test practice no other states use today.
A nervous test taker may identify the first alternative as correct and read no further.
The same is true for: “Both of the above.”
Remember to read all choices carefully.
You may also see “None of the above” as the last choice. This alternative is also a poorly designed question since it doesn’t check if you know the correct answer.
Even if it is less common, you may see a negative question that contains the word not or never. In this case, 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 ensuring 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, meaning you cannot use any aid (written, audio, or electronic) while taking the exam.
If you fail the knowledge examination, you must wait at least three days before you can retake it. You must pay a new fee each time you take 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 old, you must complete a driver training program and comply with the Graduated Driver Licensing (GDL) Program requirements. 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.
You must pass a Class D written knowledge test when transferring from another state, U.S. Territory, or the District of Columbia. Unlike many other states, DMV does not waive the written test for drivers with out-of-state driver’s licenses.
You must also pass all tests with a foreign driver’s license.
If you let your Idaho Driver’s license expire for 25 months or more, you must also retake the knowledge test.
Idaho Graduated Driver’s License (GDL) program
Anyone under 17 years who applies for their first driver’s license in Idaho must 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 the Driver Training (DT) and the Supervised Instruction Permit (SIP). They allow anyone at least 14 1/2 years and under 17 to attend public school or a 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 enrolled in a training class, the DT permit allows you to drive while a training instructor supervises. When you have completed the program, the instructor will release the permit, and it becomes a Supervised Instruction Permit.
In this next phase, you can practice your driving skills when accompanied by any licensed driver at least 21 years old and 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 violate any traffic laws while you practice driving under this program, DMV will cancel your SIP. After the cancellation, you must reapply for a new SIP, and the six months of supervised driving start over again.
Only after meeting these requirements under GDL will you be allowed to take the Idaho knowledge test.
You can schedule your road skills test if you pass the knowledge test.
After passing all tests, DMV will issue an Idaho Driver’s License.
