#1. Under Idaho Point System, you will receive a warning letter when you:

Under the point system, the department may take the following action(s) against you:

  • 8 to 11 points in any 12 months: Warning letter
  • 12 to 17 points in any 12 months: 30-day suspension
  • 18 to 23 points in any 24 months: 90-day suspension
  • 24 or more points in any 36 months: 6-month suspension.

#2. Always allow extra room in front of your vehicle when:

Be careful when you are towing a trailer or carrying a heavy load. Large or heavy vehicles cannot stop as quickly as smaller vehicles.


#3. You must obey directions, signals, and instructions from:

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.


#4. What does this sign mean?

Divided highway ends.

The divided road ends ahead. Two-way traffic will no longer be divided by a center island. You will be on an undivided roadway with two-way traffic. Watch out for oncoming cars.


#5. You meet a school bus that has stopped on the other side of the highway. The bus activates its flashing lights. When are you allowed to proceed without stopping?

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.


#6. Which road signs have the shape of an upside-down triangle?

This is a yield sign.

The yield sign means you must slow down and yield the right-of-way to other vehicles and pedestrians in the intersection you are crossing or roadway you are entering. If necessary, stop before crossing the intersection or entering the roadway.

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


#7. When it is safe to do so, a dashed yellow center line may be crossed:

A dashed yellow line means that vehicles can cross the line if it is safe to do so.


#8. What should you expect ahead when you see a warning sign with arrows in a circle pattern?

The most common sign seen when approaching a roundabout is a warning sign with an arrow in a circle pattern. When an advisory speed panel is posted below the sign, slow down to the recommended speed.


#9. Which is the best thing to do if you start to feel drowsy while driving?

Stop driving when you feel drowsy. Pull off the highway at the first rest stop or service area. A cup of coffee and a bit of stretching may be enough to wake you. If you are really sleepy, get off the road and take a nap.


#10. When you park your car on the same side as an entrance to a fire station, you must keep this distance from the driveway entrance:

Do not park within 20 feet of a fire station driveway.


#11. Moving into the same lane alongside a motorcycle:

Motorcycles are entitled to the same full lane width as all other vehicles. Never move into the same lane alongside a motorcycle, even if the lane is wide and the motorcyclist is riding far to one side.


#12. Drivers are often temporarily blinded at night by which of the following?

Glare from other vehicles make night driving hazardous. Avoid looking into the headlights of oncoming vehicles. Instead, shift your eyes down to the lower right side of your traffic lane. This keeps the light from hitting your eyes directly.


#13. Your brake lights tell other drivers that you:

When slowing down or stopping, you must give a signal to other drivers. You may use either an arm signal or the brake-operated signal lights on the rear of your vehicle.


#14. When backing up or reversing your car:

Backing requires extra caution because it is difficult for drivers to see behind their vehicles. Here are some rules you should follow whenever you have to back up:

  • Check behind the vehicle before you get in. Children or small objects are hard to see from the driver’s seat.
  • Put your right arm on the back of the seat and look over your shoulder directly through the rear window. Do not rely on your mirrors.
  • Back slowly. Your vehicle is more difficult to control while backing. Continue looking back until you come to a complete stop.

#15. If your car starts to skid, you can make the skid worse if you:

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.


#16. When must you use your headlights?

Turn on your headlights when driving between sunset and sunrise, or when visibility has been reduced to below 500 feet. (49-903.)


#17. A car passenger less than two years of age must:

Idaho law requires anyone carrying children 6 years of age or younger in a non-commercial motor vehicle to properly protect children in approved child car safety seats.

The law applies to cars manufactured with car safety belts after January 1, 1966.


#18. 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.


#19. In general, studded snow tires are allowed during winter months until:

Studded snow tires may be used only from October 1 to April 30.

Some years, the Idaho Transportation Department adjusts the dates due to weather conditions.


#20. The shape of a do not enter sign is:

The Do Not Enter sign tells you that the road or street ahead is for one-way traffic traveling in the opposite direction. You may not enter this section of roadway from the direction you are traveling.


#21. A flashing red traffic signal at an intersection has the same meaning as:

A flashing red indication means stop. You must come to a complete stop, yield to cross traffic or pedestrians, and then proceed when the way is clear.


#22. If you need to turn around on a freeway, you should:

Freeway median crossovers are for highway maintenance or emergency vehicle use only. It is illegal for any other vehicles to use them. If you need to get off the freeway or change directions, wait until the next exit to do so.


#23. In this situation (approaching the bicyclist from behind), you should:

To increase the safety margin when passing a bicyclist, move into the left lane if possible. If you do not have adequate space to pass a bicyclist, slow to the speed of the cyclist and follow him or her until you do have the room needed to pass. Do not tailgate the bicyclist.

In this situation passing on the other half of the roadway is unsafe. These are usually brief stretches of narrow roadway where it is unsafe for a motorist to pass a bicyclist.


#24. What should you do when you approach a railroad crossing and see a vehicle with this sign ahead?

Watch out for vehicles that must stop at crossings, be prepared to stop if you are following one.

All vehicles carrying hazardous materials must stop at all railroad crossings.

A school bus or transit bus must also come to a complete stop before crossing any railroad track.


#25. If you are less than 21 years, you may transport a full, sealed, and unopened container of wine:

It is illegal in Idaho for anyone under the age of 21 to possess, purchase, and attempt to purchase alcoholic beverages.

The Idaho DMV Test

Quick facts about the Idaho written test for your Driver’s License:

  Number of Questions: 40
  Correct answers needed: 34
  Passing score: 85 percent
  Time limit:
  Earliest retest upon failure: 3 days

This Idaho License Sample Test

While the real Idaho knowledge examination has 40 questions for you to answer, this practice test is limited to 25 questions in each set. To make sure you cover all items in the Idaho Driver’s Manual , you should take at least a handful of practice tests.

Each set of questions is randomly created from a large pool of DMV questions.

With every answer there is a quick feedback so you will know if your answer was correct or not. In case you got it wrong there is also a brief explanation to the correct answer.

The practice test is designed to help you study and give you an idea of the kind of questions DMV will ask on the real examination. Try to use the test as a learning tool and not only as a way of memorizing important questions and answers.

While the questions cover all important items in the Idaho Driver’s Manual, they are not inclusive of all questions that can be asked on the official knowledge test. Since both the practice test and the real test are random, you will never know which questions you will get. But the more you practice, the more you will cover, and the more likely it is that you will pass the real examination.

Idaho Graduated Driver Licensing System

The Idaho Graduated Driver Licensing (GDL) system affects all new drivers under 17 years.

Driver Training Class

If you are at least 14 1/2 years old and get for your first permit application approved, DMV issues a Driver Training (DT) permit. With this permit you can attend any public school or private driver’s training program. You must have this permit before taking any training class.

An approved training class consists of:

    30 hours of classroom instruction
    Six (6) hours of behind-the-wheel instruction
    Six (6) hours in-car observation

If you attend a training class through a public school, the minimum training period is 30 days. If you take a class from a commercial school, there is no minimum training period.

During this training period, you are only allowed to drive with a certified driver instructor.

When the training class is completed, your permit becomes a Supervised Instruction Permit (SIP).

Supervised Instruction Permit (SIP)

With the SIP in your hand you can practice driving with 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).

You must complete a supervised driving period, which must include:

    No less than six calendar months of violation-free supervised driving
    50 hours of supervised driving, of which 10 must be at night

Under no circumstances can you practice driving on your own.

Things to Know about the Knowledge Test

You must pass the knowledge test and a road skills test before DMV issues your Driver’s License.

As mentioned above, the knowledge test is a 40-question examination with a passing score of 85% (34 correct answers).

Should you fail the test, you must wait at least 3 days before you can take the test again. You must also pay the testing fee each time you take the test.

The knowledge test is available in the following languages:

  American Sign Language (ASL)


Expect the test to take about 15-25 minutes.

Read all questions and answers choices all the way through. Be alert to questions that have “All of the above” or “None of the above” as one of the alternatives.

When “All of the above” is used, all alternatives can be correct – not just the first one that you spot! It can be tricky to get these questions right, so read carefully.

If you are under 16 years, you can drive during daylight hours only. This does not apply if you are accompanied by a licensed driver who is at least 21 years of age and sitting beside you.

  Passenger restriction

If you are under 17 years, there is a passenger restriction during the first six months. You may drive with only one passenger under 17 years, unless the passengers are related to the driver by blood, adoption, or marriage.
