#1. Which is true about driving 55 mph in a heavy rainstorm on a highway with a speed limit of 60 mph?

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.


#2. If you are 21 years or older, you may carry a full, sealed, and unopened container of wine:

It is against the law for any person in a motor vehicle on a public roadway to drink alcoholic beverages, or to transport open (unsealed) containers of alcoholic beverages. It is a misdemeanor for a driver in actual physical control of a vehicle to violate the open container law – it is an infraction for passengers. An unsealed alcoholic beverage container may be legally transported in the enclosed trunk compartment or behind the last upright seat of a vehicle without a trunk compartment.


#3. When is it important to turn on your headlights?

Turn on your headlights when driving at night (between sunset and sunrise), or when visibility has been reduced to below 500 feet. The grey hours of twilight and dawn are the most dangerous times of the day. If you must drive in fog, dust storms, or in heavy rain, reduce your speed and use low beam headlights.


#4. Anti-lock brakes are of most use when you are:

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.


#5. Two solid yellow lines mean no passing. Do not cross these lines unless:

Solid yellow lines mean no passing is allowed. Neither lane of traffic can cross the lines unless they are turning (if it is safe to do so).

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.


#6. Before receiving a driver's license, a new driver under 17 years old must hold a Supervised Instruction Permit (SIP):

Under the Graduated Driver’s Licensing (GDL) Program, a teenager under 17 years of age will be required to complete a minimum six-month, violation-free supervised instruction period.


#7. Into which lane should you turn when making a right turn from a one-way street into a two-way street with multiple lanes?

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.


#8. If you are involved in a minor crash without injuries and if you are blocking the flow of traffic, it is your responsibility to:

You may move vehicles that pose a traffic hazard before the police arrive.

Idaho’s Quick Clearance law requires anyone involved in a crash (on an interstate or major divided highway), that does not cause a death or injury, to safely move the vehicle to a shoulder, median or emergency lane.


#9. You approach a stopped school bus with flashing red lights from the opposite direction on a roadway with two lanes going 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 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.


#10. What shape is the road sign that tells you there is a school crossing ahead?

Five-sided sign black on yellow is used only to warn of schools and school crossings. As you approach this sign, slow down and watch out for children, stopping as necessary. New fluorescent yellow-green signs may also be used.

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


#11. It is a hot day. You have a sleeping child under two years in the back seat. Can you park and leave the child alone in the car?

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.


#12. Which light indicates that you must always come to a complete stop at an intersection?

A steady red circular indication means stop. Come to a complete stop before you reach the stop line, crosswalk, or intersection. Remain stopped until the light changes and cross traffic clears the intersection.

You may turn right after stopping and yielding to cross traffic except where posted otherwise. You may turn left into a one-way street after stopping and yielding to cross traffic unless posted as no-left turns allowed.


#13. When changing lanes on a freeway, you should signal for:

Proper signaling may prevent a rear-end collision. Always signal for at least five seconds before making a lane change or exiting a freeway.


#14. A vehicle carrying this sign:

All slow-moving vehicles must display the approved emblem for slow-moving vehicles. This sign has a red perimeter and orange center and is primarily on off road vehicles (implements of husbandry, construction equipment, etc.).

When you are approaching a slow-moving vehicle, you should slow down and approach the vehicle with caution.


#15. Before taking off in freezing weather you should clear ice and snow from your car's:

Before driving, remove ice and snow from your vehicle. Clear all windows, windshield wipers, headlights, and brake lights. Clear ice and snow from your vehicle’s roof so they do not blow off while you’re driving and create hazards for drivers behind you.


#16. 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.


#17. When entering or crossing a highway from a driveway in a residential district:

When entering from an alley, driveway or building, you must stop immediately prior to driving onto a sidewalk or onto the sidewalk area. You must yield to pedestrians and other drivers.


#18. While on the entrance ramp to a freeway, you should:

Once on the ramp, check traffic around you and on the freeway. Signal and begin looking over your left shoulder for a gap in the traffic large enough for your vehicle to fit into without crowding anyone.


#19. To prevent skidding on slippery surfaces, you should:

Be alert to slick road conditions that may cause skidding, especially during the winter. Adjust your speed, as necessary. When you must stop, slow down in advance. Avoid fast or sudden turns. Never hit the brakes so hard you lock the wheels, or you could lose control of your car.


#20. Where is it illegal to park?

Parking is not allowed in front of a public or private driveway (Idaho Statutes Chapter 6, 49-660).


#21. Which is true about tailgating (following another vehicle too closely)?

Most rear-end collisions are caused by vehicles following too closely.


#22. 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.


#23. This sign tells you that:

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


#24. You must stop before railroad tracks:

By law, you must stop when:

  • There is a stop sign.
  • A warning signal tells you a train is approaching.
  • A crossing gate is lowered.
  • A flag person signals the approach of a train.
  • A railroad train emits a signal, indicating that the train is an immediate hazard.
  • An approaching railroad train is plainly visible and is in hazardous proximity to such crossing.

#25. You are about to drive home. You cannot find the glasses you need to wear for safe driving. Which of the following is your best course of action?

If you wear glasses or contacts during the vision screening, a lens restriction will be placed on your driver’s license. If a lens restriction is placed on your driver’s license, you must always wear your glasses or contacts when operating a vehicle or you could be cited and lose your driving privileges for a period of time.

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.
