#1. Even if you do not see other vehicles around, you should signal:

Always signal before every lane change and before pulling away from the curb, even when you do not see other vehicles around.


#2. Which is generally true about 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.


#3. You are driving on a four-lane highway with no signs or markings to control turning. From which lane should you make a right turn?

Give your signal 100 feet before the turn and approach the intersection in the right-hand lane, staying as close to the right curb as is reasonable. Yield the right of way to pedestrians and vehicles that have the right of way. Watch for bicycles that are approaching from the right between your vehicle and the curb. Then turn into the right-hand lane of the cross street. Do not swing wide.


#4. Which of these statements about motorcycles is true?

Allow more than three seconds following distance between your vehicle and a motorcycle. This allows you and the motorcyclist enough time to maneuver or stop in an emergency.


#5. If you pull off the road and stop because of heavy fog, you should:

It is safest not to drive in fog, dust storms, or in heavy rain. If you must drive during these conditions, reduce your speed. If conditions get too bad, pull off the road and stop. Do not creep along – somebody else may crash into you. Also avoid using your four-way flashers while moving – other drivers may think you have stopped.


#6. When parking on a public road, you must park parallel to and within:

When parking on a public road, you must park parallel to and within 18 inches of the curb or edge of the roadway, facing in the same direction as traffic on your side of the road.


#7. Driving between vehicles of a funeral procession is only allowed:

If you see a funeral procession on the road, do not drive between or join vehicles in the formation unless you are authorized to do so by a police officer.


#8. Driving under the influence of a drug that impairs your ability to drive safely is:

Remember, it is illegal to drive under the influence of any drug which impairs your ability to drive safely. If you have to drive, you should avoid taking any drug that might hamper your ability to operate your vehicle.

When your doctor writes out a prescription, ask the doctor if it will make you drowsy or otherwise affect your driving. If so, let someone else drive while you are taking the drug.

Over-the-counter drugs include such things as pain relievers, lozenges, and cough and cold remedies. By law, these drugs must provide directions for use. Read the label. If driving is discouraged, don’t get behind the wheel.


#9. What does this sign mean?

Reduction of lanes (Lane ends). There will be fewer lanes ahead. Two lanes of traffic will soon become one lane of traffic. Right lane traffic must yield when merging.


#10. The following equipment is allowed on your car, except:

Equipment that is not allowed:

  • Red or blue emergency lights. These are authorized for emergency vehicles only.
  • Sirens, bells, and whistles.
  • Any muffler cut-out or bypass that makes the exhaust system amplify or increase noise.
  • More than two spotlights.
  • More than two auxiliary lights in front.
  • More than two fog lights in front.
  • More than two cowl or fender lights.

#11. You need to pass a bicyclist ahead. Which is the best thing to do?

To increase the safety margin when passing a bicyclist, move into the left lane if possible. If you are not able to change lanes, pass with as much clearance as possible – a safe margin is at least three feet.


#12. Which of the following must you obey over the other three?

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.


#13. When driving in a fog, you should:

It is safest not to drive in fog, dust storms, or in heavy rain. If you must drive during these conditions, reduce your speed, and dim your lights to low beam.

Light from high beams will reflect back, causing glare and making it more difficult to see ahead.


#14. The eight-sided shape is used for which road signs?

The stop sign is the only eight-sided traffic sign. It means that you must come to a complete stop before entering the intersection ahead and yield to traffic close enough to be an immediate hazard. If there is a crosswalk, stop before entering it.

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


#15. On which side should you pass a vertical panel like this?

If the stripes angle down to the right, go to the right. If the stripes angle to the left, go to the left.


#16. If there are two railroad tracks next to each other:

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.


#17. You can drive off the roadway to pass another vehicle on the right:

You may pass a vehicle on the right only in certain situations, and only if you can do so safely. Such a movement shall not be made by driving off the pavement or roadway.


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

At speeds up to 35 miles per hour, most tires grip the road surface even when it is wet. As speed increases, the tires cannot grip the road as well. Replace tires as soon as they become worn and keep tires properly inflated. In Idaho, tires must have at least 1/32 inches of tread on them


#19. A traffic signal with a yellow arrow means:

A yellow circular indication warns that the signal is about to change to red. This means that the time to make a protected turn is ending. 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.


#20. Leaving a sleeping baby inside a car is:

When it is hot outside, do not leave children or pets in a vehicle unattended.

On hot summer days, the inside of a car can become dangerously hot in a short period of time. One study found that with the windows up and the temperature outside at 94 degrees, the inside of a car can heat to 120 degrees in just 30 minutes, and up to 132 degrees after one hour.


#21. What is this sign?

This is a regulatory Speed Limit sign. It shows the minimum speed you are allowed to travel.


#22. When your gas pedal sticks:

Keep your eyes on the road. Push the clutch in on a manual transmission or push the gear shift lever of an automatic transmission into neutral and brake to a safe stop. Then turn the ignition off. Never turn your vehicle’s ignition to the lock position while it is still in motion because the steering will lock, and you will not be able to steer the vehicle.

If you have time and are driving at a slow speed, lightly tap the accelerator pedal a few times to see if your engine speed returns to normal. If tapping fails, try prying it up with your toe.


#23. What does the markings in center lane (B) mean?

Always use traffic lanes as they are defined by pavement markings and road signs. When a lane is marked with a straight arrow and the word ONLY, you must proceed straight ahead.

When a lane is marked with both a curved and straight arrow, turning or proceeding straight ahead is allowed. Vehicles turning must remain in their lane of travel until after completing the turn.


#24. 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.


#25. You are driving 40 mph in a heavy rainstorm on a highway with a speed limit of 50 mph. You can be cited for driving too fast:

Idaho law has a basic rule requiring you to drive at a speed that is reasonable and prudent at all times. If you drive too fast for existing conditions – even if you are driving under the posted speed limit – you are violating the basic rule law.

This applies to all streets and highways where maximum speed limits are set by law or posted. Whenever you are driving, you need to think about how your speed affects other traffic (including pedestrians and bicycle riders). You also need to think about the road surface (the presence of ice, snow, rain, or rough pavement), hazards at intersections, visibility, oncoming traffic, curves, and any other conditions that may affect safety.

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.
