Passing on the left is prohibited when approaching a grade or a curve where your view is obstructed. Passing is also prohibited within 100 feet of a railroad crossing, unless otherwise indicated by traffic-control devices.

You must stop for a school bus that is loading or unloading students.


#12. When two vehicles from different directions arrive at the same time at an intersection where there are no signs or signals, which one must yield?

At an unmarked or uncontrolled intersection (no signs or signals), the vehicle that arrives first, goes first. If two vehicles arrive at the same time, the vehicle on the left must yield to the vehicle on the right.


#13. If you are involved in a collision, you must:

Stop as near to the scene as possible without blocking traffic. You may move vehicles that pose a traffic hazard before the police arrive.

Do not try to move an injured person from a wrecked vehicle unless you have the necessary medical training or there is an immediate danger, such as fire.

Bells, sirens, and whistles may be used only by emergency vehicles.


#17. You should check your rearview mirrors:

#19. 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.


#20. When making a U-turn near a hill or curve, the law requires that you:

When making a U-turn near a hill or curve, the law requires that you be able to see 500 feet in either direction.

U-turns are not legal everywhere, so first look for prohibiting signs. U-turns are always prohibited in no-passing zones.


#21. After a train has passed at a railroad crossing with more than one track, you should:

After a train passes, watch out for a second train. Do not start up until you’re sure no train is approaching on another track.


#22. In general, large trucks:

Generally speaking, the bigger vehicles are:

  • The bigger their blind spots.
  • The more room they need to turn or change lanes.
  • The longer it takes them to stop.
  • The longer it takes them to pass.
  • The more likely you’re going to be the loser in a collision.

Safely sharing the road with large trucks and buses requires knowledge of their special limitations. When you are near large vehicles on the road, pay special attention.


#23. Anti-lock brakes are most effective when you:

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.


#24. In most situations, you can park legally:

Never park or leave your vehicle unattended on a bridge, on a crosswalk or within 30 feet of a stop sign. Parking on a hill is allowed if you are far enough from any travel lane to avoid interfering with traffic and visible to vehicles approaching from either direction.

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.

Idaho Driver License - Testing

Your First Idaho Driver’s License

Before DMV issues your first Idaho driver’s license, you must be at least 15 years old.

A parent or legal guardian must certify that fifty (50) hours of driving were completed (10 of which were at night), and grant permission to issue the license.

The first license comes with some restrictions:

  Night curfew

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.
